Watching the screen

Television was a revolution of technology. The majority of the families have a television at home.

On one hand it’s very useful because you can watch the news the weather forecast… If you are bored you can follow series, you can see films and cartoons (for the children) and you can listen to music too. If you don’t like one channel because you can’t put up with the host, the actor or the program you can change it and watch anther one, but if you like it you can keep on watching it. You can find out about information in documental too.

But on the other hand, it’s prejudicial for different reasons. It can be harmful for your eyes and sometimes it make to you don’t meeting your friend or don’t doing sports, call off something, because you want to stay in the sofa or in the bed watching the serial o watching a film eating and this makes you become fat.

To sum up, watching TV is a great entertainment, but you must be careful with the time you spend watching it. Sara

Computers world

Computers are a very useful invention. There have got a lot of advantages;

on the one hand, you can do a lot of things. You can write with a very good

presentation, you can paint, you can see photos with high quality, you can

easily create presentations and furthermore you can download more specific

programs to design, to calculate, to organize you… Moreover, through

computers you can surf the internet! And I think this is a fantastic advantage.

Computers have a place to introduce CD’s too, so you can do things such as

listen to music, watch films or play videogames.

On the other hand they can also prejudice you. Computers can create high

addiction if you don’t use it correctly. There are people that stay to many

hours in front of it. It can create vision problems too. In addition, if you don’t

copy your computer’s information in a pen or a disk, if your computer breaks

down, you will lose it all.

In conclusion, computers can be a fantastic work tool only if you use it

correctly. Gemma

Youtube

Youtube is a good invention. On the

one hand, It allows million of

people to see videos of an almost

unlimited duration. But the videos

that there are hung are very

controlled. If they contain

pornography or similar things they

eliminate them. Another of the

good things that it has, is that it allows you to earn money if you have

many visits. For example the youtuber “HolaSoyGerman” wins €260.000

per month.

On the other hand, it has bad things. First, the people are bothered by the

ads that they show before some videos. Secondly, there are videos that

cannot be reproduced in certain countries. And finally it threatens the

people’s privacy.. However, if it is used correctly it does not turn out to be

dangerous, but if it is not watched, it can be dangerous. Ferran

Thumbs up

Many people spend a lot of their time on a videogame, but have you ever

been playing videogames for a long time in a day? Have you? If you have

done it, you’re addicted.

On the one hand, when children are bored, they can play in order to don’t

feel bored. Videogames increases meeting new friend via internet and you

can play with people around the world. Children concentrate on doing one

task; they coordinate hands and sight and grow skills.

On the other hand, the videogames are so dangerous, because children are

addicted and they want to play all the time. Most of the videogames are

about war or crimes. They think that play with videogames is a priority.

Children who play can be fat and have health problems, vision problems and

photosensible epilepsy. Videogames increase hyperactivity.

FACEBOOK, GOSSIP SOCIAL

NETWORK

Facebook is a social network that you can use to communicate

with people and see all the photos.

On the one hand, Facebook is a social network where you can

see the people that isn’t here. Also if you haven’t seen one

person, you can talk to her or him and see photos. You can

gossip and look at all their photos and posts.

On the other hand, Facebook has disadvantages. For example,

someone you don’t know can make up a story and cheat on you.

Also all the people can see you. This is dangerous. In addition,

you can become addicted to it.

To sum up, Facebook is a good invention. However, if you abuse

or misuse it, you can become addicted. You have to use it

carefully. Sandra

VIDEOGAMES Videogames have revolutionized the world of the technology.

On the one hand, videogames are very funny and they are a

good leisure activity, and it is a means of communication,

because they have an option of online. The online game is an

invention that allows people to play with people around the

world. The best videogame of 2013 is GTA (Grant theft auto)

which has made a profit of 800 million dollars.

On the other hand there are disadvantages connected to

videogames, as for example epilepsy, photo sensitivity and

illnesses that effect the eyes.

And if you play too much they can produce obesity, headaches…

The conclusion of videogames is that it’s funny’s but playing too

much is bad for your health. Edgar

MEETING E-FRIENDS

Facebook is one of the most well-known social networks. It’s very

simple: with only your e-mail, and if you are 13 years old you can use it.

There are more than 400 million users in the word.

On the one hand, Facebook is a very important invention because you

can meet or chat with people around the world, and that’s incredible. You can publish

all the things you do during the day, share photos, gossip other people…If you want,

with Facebook you can search events, jobs or things like that.

On the other hand, Facebook can be dangerous. All the people can see you and can

know everything about you. So that is very dangerous! You have to control what you

share and what people you invite to be your e-friend. It’s also dangerous because if

you don’t set your profile private, the images that you have, can be expanded around

the word, or be used for strange things.

In conclusion, Facebook can be a very good social network, but you have to be

conscious what things you do and watch. Mariona

INSTAGRAM

Instagram is a powerful invention to share your day by day by posting

photos and videos. Everybody I know has an account on this social

network.

On one hand you can share photos with your friends. You can also gossip

other people you want to know or you know. Furthermore you can find

amazing photos from professional accounts. Last but not least

communication between people has become very visual and we don’t

need words anymore.

On the other hand if you haven’t got you profile with privacy someone can

save your photos or videos. What is more you can become addicted. You

can also have health problems if you stay all day using it. For example you

can have a pain neck or your eyes can be affected.

In conclusion this App is amazing if you know how to use it. Júlia

Mobile Phones

On the one hand, the mobile phone is a useful invention. For example to speak with

whom you want where you want even when you are walking. You can call rapidly in

case of an emergency. It facilitates the communication with people that you do not

have nearby. It Is comfortable The battery lasts more in comparison of the first ones

Bye,bye traditional books

So many people believe that the new technology is better than the

traditional things. Nowadays, e-books are becoming very popular, but the

new technology has a lot of problems.

One of the good points of e-book is that they are light and they are

handful. For example, if you travel a lot it’s good to have place in you

baggage and don’t have an excess baggage. Furthermore, an e-book it’s

cheaper than a traditional book; you have only to pay half than a paper

book. In addition, if you want to buy an e-book it’s immediately and you

don’t have to move to a library or if you want to read a book at night and

you have to wait until the library opens the next morning.

On the other hand, e-books have to been charged and that means that you

have to remember every night to charge it. Moreover, if you read without

light you can get health problems; for example, the e-book has an own light

and so many people reads at night and the turn off the light and reads only

with the e-book’s light. Last but not least, many people prefer a traditional

book because for the smell and the touch of the paper and you don’t have

that on an e-book.

In conclusion, the e-books are becoming popular and they are growing the

sales. As far as I’m concerned, I prefer traditional books but I think that

e-books are good, too. Anna

A USEFUL TOOL

Everybody knows that computers are a great invention in this century: a very useful

tool that also includes many problems and disadvantages.

On the one hand, computers are a very modern and useful invention. People use them

to connect with others that live far away and also to connect to social networks such

as Facebook or Twitter. You can also play games, take pictures, search for information

and keep up with the news around the world.

On the other hand, there are also many disadvantages. It isn’t a very secure tool

because experienced hackers can enter your computer and discover your information.

There are also many social networks that promote communication between people.

However they invite people to let all their information around the internet, where

everybody can see it.

In conclusion, a computer is a very important tool nowadays, but people have to be

careful where they enter around the internet to avoid problems or hackings. Clara

SPEAK AND WRITE TO THE PEOPLE

Mobile phones are one of the most important inventions of the world. Nowadays all of us are

connected to mobile phones.

On the one hand, the mobile phone is useful invention because if something happens you can talk

to your family or anyone of your contacts. For example imagine if you are in the street and you

can’t find your destination; you can phone your friend with your mobile phone, but if you don’t

Page 11: Useful Inventions

phone your friend you can use some social networks, for example: whatsapp, snapchat, line,

etc..

But on the other hand, there are some problems with mobile phones. For example, some people

in Europe and North America can’t avoid chatting for long hours. Nowadays there is a problem

that we should change. For example you are with your friends in a bar and there are some

friends that there are with their mobile phone instead of speaking with other people.

In conclusion, the mobile phone is very good for an emergency or to find out some information,

but we must give up our addiction with that object. Joan

Videogames

Videogames have become really popular in the 21st century, and

most teenagers play or have played them. But, are they always

good?

On the one hand, videogames can entertain you for hours and let you

meet your friends while you are at home. You can also meet people

from other countries and try to speak their language with them. If

they are kind, you can even make new friends.

On the other hand, videogames can entertain you for “too long”, so

you can develop and addiction to them. In a similar way drugs do,

Page 12: Useful Inventions

they can isolate you and make you stop meeting with your friends in

real life, or even make you lose them. This is why you should pact

with them when to meet in videogames but also when to meet in real

life. Another problem with online videogames is that the people you

meet there can be less friendly than you expected, so you can argue

with them instead of having fun.

To sum up, videogames are a good option of entertainment and in a

social way too; but you should try to not spend too much time

playing them and find other ways of entertainment to keep you away

from the risk of an addiction. Enric

MOBILE PHONES

The mobile phone is a good invention because we use it to talk with your

family and friends or for an emergency.

The advantage of the mobile phone is that we use it to talk to other

people: family, friends, with people of the job… Also, when somebody

came up with “watsapp”, we have used the mobile even more,

because we write to a lot of people and have a lot of conversations.

Talking to many people at the same time is good, as it is sharing photos.

The mobile phone is a good technological tool but it has disadvantages,

too.

One disadvantage is that the mobile creates a lot of addictions over all

for the adolescents and for their parents. Another problem that they

have is that sometimes people share a lot of photos that can be

inconvenient for other

people. This problem is

rising among

adolescents. Also in the

mobile phone the people

have “Facebook” and

“Instagram” and they

can create an addiction

with these tools.

In the end you should be

careful with the mobile phone and you should use the “watsapp” not all

day long. It is a good technology for your communication. Maria

SOCIAL NETWORKS

MEETING E-FRIENDS

Whatssap is an app for mobile phones which a lot of people use. On the one hand, it’s

very good because you can talk to your friends or to your family at any moment and

the message is immediate. Also you can send photos, videos, contacts, localizations,

etc.

On the other hand, it causes a lot of addiction. Nowadays, a lot of young people use

whatssapp at every moment. This influences the people. For example, if you go

walking to the city, you come across with a lot of people that is using a mobile phone

and probably whatssapp. Also influences the oral communication because a lot of

people give up meeting and start chatting by whatssapp. It is also very difficult to give

up whatssapp because it causes a lot of addiction.

To sum up, whatssapp is very good because you can talk to people immediately but

also causes a lot of addiction. Paula

The mobile phone and the friends

On the one hand, the message with mobiles (whatsapp) are a very good invention among the

young people ,because communicating with friends is okay .Another advantage of whasapp is

that you talk at the moment and you can talk to 20 people at the same time everywhere in the

world

But on other hand to make out is horrible because people through whatsapp say a lot of trifles

and after in the face can’t say anything. The boys are very shy in person and a lot of boys do

not do sports but they stay at home using whasapp.

In conclusion, whasapp is a very good invetin but not so good in nowadays society. Mario

MOBILE PHONE, CONNECTING PEOPLE:

One the one hand, mobiles phones are inevitable in our lives. Actually, 90% of

the population have Mobile phones. It is a good invention for communication,

because you can talk to people around the world. It is a good working tool too.

There are people that wouldn’t be able to work if they didn’t have a Mobile

phone. For example, if you want to watch a series and you are in one place that

doesn’t have a tv, with your mobile you can watch it.

On the other hand, there are disadvantatges to the mobiles phones. There are

people that they can find where you are trough the mobile phone. The mobiles

phones produce negative waves. Because of this experts recommended not to

use it a lot, and not to sleep near mobiles phones.

In conclusion, mobiles phones are good but you wouldn’t use it a lot because

they produce negative effects for our health. Laura

Today’s Music: Innovative or boring?

Some people say that today’s music is all the same. I’m here to tell you the advantages and

disadvantages of the music of my generation.

On the one hand, most of the people that are against this music, say that all the songs are

equal, boring and the same type. That is wrong, because there are some groups like Hollywood

Undead, some songs of Imagine Dragons, Porta, Daft Punk… that are very different. Nowadays

the variation of the music has increased a lot; even there have been formed new types of

music like techno or dubstep, for example.

Also, there are people that think that their generation music was such better than now, but

this is hypocritical because some songs of their music is the same type, but without so many

electronic instruments.

I’m not saying that my generation music is better than the others, so don’t misunderstand. On

the other hand, there are some disadvantages of today’s music.

In the past, freedom to express yourself by singing for example, was more controlled than

now. I think that is good to express yourself, but there are some people that exchange the

concept of freedom to express yourself with freedom to insult everyone that you want or to be

too sincere. These types of people often write songs attacking a group of people with different

ideologies (political, religious…) with no reason.

It’s true that there are some singers that are very similar, like Rihanna, Katy Perry, Shakira…

Apart of this, I think that people shouldn’t globalize a type of music because of the age of its

creation. Ingrid

MOBILE PHONES AT SCHOOL

In my school, we aren’t allowed to use mobile phones, but I think that we

should be allowed to use mobiles phones during break time.

On the one hand teenagers can listen to music, speak with others boys or

family. Teenagers are happier if they listen to music.

On the other hand teenagers tend to talk less face to face and more

through Mobile phones. They can take embarassing photos at teachers or

students and the students would use mobile phones in class and disturb.

They can cheat in exams and pass with good marks but in fact they don’t

know anything. Arnau

Mobile phones

Mobile phone are useful to make a calls, connect in internet, speak with your friends and know the new news...

In recent years the communication with phones has improved a lot. Nowadays people totally depend on their phones.

Different brands of mobiles are Iphone, Samsung, Blackberry, Sony, Lg, Huawei…

Iphones are the most sold brands of telephones, more than others brands.

Advantages disadvantages

-listen to music -get distracted -speak with your friends - your privacy -search in the internet -bad habits

- Search for information Anna

Page 17: Useful Inventions

SOCIAL NETWORKS YES OR NOT ?

Everybody has an account in a social network: Facebook, Instagram,

Twitter, Digg, Flickr, Linked, Messenger... Is this is good or bad?

Social networks facilitate open communication, leading to information

discovery and delivery. It also allows employees to discuss ideas, post

news, ask questions and share links. It also improves business reputation

and client base with minimal use of advertising. For companies social

networks expand market research. For individuals, it is a bit different. You

can keep in touch with other people who are far from you. You can upload

photographs, videos and share what you are doing.

On the other hand, people who you don’t know may see your

photographs and videos and they may know where you live or where you

play football, for example. It’s difficult to control what children see on the

internet and people can cheat on them. Videogames offered by social

networks may be dangerous and you spend too much time. Social

networks open up the possibility for hackers to commit fraud and launch

spam and virus attacks. Ale

MOBILE PHONES

Mobile phones have evolutionated a lot from the first model to nowadays.

Page 18: Useful Inventions

On the one hand, I think that they’re very useful, because you can use them to call whoever you want at any moment you need to. Also, we can use mobile phones to search different things on the internet, chat by WhatsApp, take photos to remember happy moments… Mobile phones are also used by many people to keep up with important things such as the latest news, play games or listen to music. On the other hand, mobile phones also have disadvantages. Some people get very obsessed with mobile phones and it seems that they can’t live without them. We forget out obligations and we waste a lot of time using the mobile phone. We must learn to sort out our schedule and do, first of all, our obligations and then, if we have free time, use the mobile phone. Maria

The two faces of television

I could live without television but some people couldn’t. This could be a good or a bad thing:

On the one hand, the TV in a useful invention. Is used to keep up with things such as the latest

news, play video games, watch films, listening to the radio-TV…. Also is an entertainment for

people because you can watch all kind of TV shows, films, documentaries… This it means that

you can always watch what you want.

On the other hand, there are disadvantages to the TV such as there are inappropriate

programs that children shouldn’t watch and also is not healthy because children spend many

time watching TV and less time doing homework, exercise and healthy things. In addition,

people might give up buying newspapers.

To sum up, the TV is useful and people will keep on using it. However, it can become a

problem if is not used right. Esther

About videogames.

On the one hand, videogames have positive things such as develop the overcoming

instinct, increase their speed of thinking, stimulate concentration, develop reflexes and

mental agility and improve hand coordination. People think that videogames could

affect your relations with people but promote teamwork in the case of multi-player

games, and you can obtain new relationships by the games. There are other reasons to

play videogames, for example, to disconnect of fatigue of a day's work or played in

family, can help strengthen ties and have a fun afternoon.

On the other hand, videogames can be very bad if you haven’t got control over them:

you can become an addict, giving constant displays of anxiety and nervousness. This

dependence also makes you stop and interact with your friends and pay attention to

your environment. In addition, children may be exposed to content not suitable for

their age, because some games contain scenes of sex, violence, use foul language…

You also have risk of overweight or obese for have a sedentary life. Earlier I talked

about the new social relations, but to connect with other players across internet, you

can meet undesirable people or provide information which should not. Another bad

reason is that consoles and videogames could be very expensive.

In conclusion, most the people that don’t like videogames are the parents, because

they think that videogames produce addiction or increase violence instinct in their

children but it all depends on the type of game you buy to your child. For example,

there are a lot of educative games that helps to your child in the school. Finally, I can

say that videogames are one of the best ways to have a good time. Pau

I LOVE TV PROGRAMMES

TV is present in our lives. Nowadays, in every homes there is at least one TV.

On the one hand, TV is a machine for entertainment. For example, if you don’t

know what to do in a free afternoon or in a free night, you can watch some TV

programmes that you like, such as a comedy programme or a quiz show. It is a

topic for conversation; with your friends you can comment a chapter of some

serial, film or any programme. TV is useful for spend time with your family all

together without worries.

On the other hand, TV for example, at night, after your dinner you watch TV and

it’s very difficult to give up watching TV. Also, a child can turn on the TV and

come across an inconvenient programme like a scary film.

The time you spend watching television could be used to do sport, study or do

something useful.

Page 20: Useful Inventions

To sum up, TV is an entertainment for us when we are relaxing but also it is a

waste of time. Nàdia

Mobile phones Nowadays everybody has a mobile phone. Even there are people that have two

mobile phones, the mobile from the job and the particular mobile phone. Is this

good or bad?

On the one hand, mobile phones are necessary in our lives. For example if you

are lost you have the mobile phone to communicate with your friends, your

family, the police… It is also an advantage that you can send instant messages

without the need to stay at home with your computer.

On the other hand, there are disadvantages to the mobile phones. If you meet

with your friends, the most of the time you talk to people using your mobile

phone but sometimes you forget talk to people face to face.

In conclusion, the mobile phone is a way to communicate for emergency but not

in excess for silly things. Andrea

Page 21: Useful Inventions

SOCIAL NETWORKS ARE

BAD AND GOOD

On the one hand social networks are good because you can communicate

with people that are far from you, and the communication is very fast.

Also you can find work and a lot of information. However, the most usual

function is to communicate with other people, especially adolescents.

One the other hand social networking can be bad both for those who use

them and for those who handle them because a lot of people use social

networks to know (gossip) everything about you especially by Facebook,

given that you can upload photos where you stayed. There have been

cases in which social networks have been used to kidnap children.

In conclusion, you have to use social networks cautiously. Sergi

Page 22: Useful Inventions

Social networks Nowadays people have an account in some social networks. On

the one hand, it is important for entertainment. If you don’t have

any friends you can meet friends. But when you are an old man,

you don’t remember the password of your account or you log off

to the social networks.

On the other hand you don’t know who you are talking to.

Perhaps he/she is a pederast. You can talk to your friends from

your home and it is very comfortable. You talk to people using

the social networks but sometimes you forget talk to people face

to face. But one problem is that in social networks there are

hackers and assassins. But if you have privacy policy is correct,

people you don’t know can’t see your account. Jimmy

MOBILE PHONES

Mobile phones are a useful invention. For example if you have an accident

you can call your mother or in an emergency. You can look for information

on the internet and send messages to your family and your friends and you

can phone to say anything. You can

use mobile phones to do wrong

things like jokes to people or make

up stories, or see something not

allowed for children on the

internet or use a wrong vocabulary

to talk with your friends. And you

can send photos and videos to the

people and connect to the social

networks. Using mobile phones for

long is bad for your health and sometimes you are more agresive and mobile

phones create adiction and is good give up mobile phones. Vladi

FACEBOOK

On the one hand, social networks are useful to spend time on the computer, chatting and

showing photos to your friends. For example, if you have a meeting you can speak to your

friends on the internet, and if you have a friend in another country you can contact with him.

You can upload photos of what you have been doing on your week. It’s a good source of gossip

too. You can know who is with that boy or ho has been partying.

On the other hand, it can be dangerous. Sometimes you don’t know who you are talking to.

This means that they might tell you information that it isn’t true. You never can trust someone

on social networks. You can be cheated and they can also take personal information from you.

This information can be used against you, and you can be in a trouble. You have to be careful

with who you’re speaking and what kind of photos do you send.

In conclusion, the social networks are very useful if you know how to use it, but it can become

a problem if you don’t used sensibly. Laura

Page 24: Useful Inventions

MOBILE PHONES On the one hand, mobile phones are a useful invention. For example, if you have an accident you

can call the police, the fire brigade or your family. You can also call or send text messages to

your friends and people you know. Mobile phones is also used by many people to send photos to

their friends.

On the other hand, there are disadvantages to the mobile phones. For example, using a mobile

phone for long periods is thought to be bad for your health, and sometimes it is difficult to control

the time you are spending in mobile phones. In addition, people might give up sending letters and

or talking face to face.

In conclusion, mobile phones are very useful and people keep on using they. However, people

waste a lot of time with mobile phones, but they are a very good solution in particular cases. Alex

MOBILE PHONES

The mobile phone has changed the form in which we work and we live our

lives. Every time there are more people who use the mobile phone to

work and for that reason the great demand of the product. Mobile phones

are very useful nowadays, but not in excess.

On the one hand, they permit to keep in touch with many people, it is a

useful tool. One of the main advantages of the mobile phone is that you

can call to any part of the world. Another advantage is that you always can

be located with this device if you have any emergency.

Page 25: Useful Inventions

On the other hand would be sometimes the unnecessary use that young

people give to the mobile phone, they become addict. Another

disadvantage would be the lack of time in our lives and for that reason we

depend more on the telephone.

I really think that it is a great invention, according to the use that we want

to give to phone. Utility or dependency? That is the great problem. If we

use it responsibly that will make our lives easier. Robert
