Questions 1 - 2

Read the text below carefully and answer the questions that follow.

Microbiological control agents like bacteria produce toxinsthat kill larvae as well as adult mosquitoes when mixed with

insecticides. However, through environmental management

mosquitoes can be exterminated by modifying the

environment to make it unsuitable for mosquito breeding.

B They modify the environment for mosquitoes

C They produce a poisonous substance that can kill mosquitoes

2 What does the word exterminated in the passage mean?

A eradicated

D extinguished

Question 3

Read the text below and answer the following question.

A research has found out that those who eat fish high in omega-3

fatty acids would score lower on measurements of hostility, including

Questions 5 - 6

Read the text below carefully and answer the questions that follow.

Gold, a precious metal, is prized for two important characteristics. First of all,

gold has a lustrous beauty that is resistant to corrosion. Therefore, it is suitable

for jewellery, coins and ornamental purposes. Another important characteristics of

gold is its usefulness to industry and science. For many years, it has been used in

hundreds of industrial applications. The most recent is in astronauts suits.

5 Gold is suitable for jewellery, coins and ornaments because

A of its lustrous beauty

B it is resistant to chemical damage

C it does not need to be polished

6 We can conclude from the text that gold is valued for

A its usefulness to industry and science

B not only for its beauty but also its utility

C its beauty that remains forever

Questions 7 - 8

Read the following text and answer the questions below.

Some rivers start life as springs. Others are fed by melting glaciers. Most rivers come

from the rain and snow that falls uplands. Water runs along the surface in small rivulets.

These rivulets may join to form a small stream. This will then begin to erode a valley.

The valley-sides themselves provide slopes for other tributary streams to flow down.As the amount of water increases, the river grows bigger. At the end of its journey,

the river flows to the sea.

7 Rivers do not originate from

A rain and snow

B springs and glaciers

C streams and rivulets

8 Which of the following shows the correct sequence for the journey of a river?

A Snow river stream rivulets sea

B Springs river rivulets stream sea

C Rain stream river rivulets sea

D Melting glaciers rivulets stream river sea

Questions 9 - 10

Read the text below carefully and then answer the questions that follow.

Firefighters Take The Heat, No Sweat

What good is a protective vest if it heats the body so much that firefighters get too hot to carry

out their work? Now, there is a new vest designed by Australian scientists. It is to be worn under

bulky protective clothing. It has a series of pipes with vapour-filled cavities that soak up the heat

and releases it via a vent. This new jacket lets wearers work four times longer in temperatures

above 95 C.

9 How does this vest help firefighters?

A It reflects heat

B It is worn under bulky clothing

C It is designed by Australian scientists

D It lets wearer work in very high temperatures

10 The following are parts of the design that enable heat to be removed from the vest EXCEPT

A pipesB vents

C water-vapour

D bulky clothing

Questions 11 - 12

Read the text below carefully and then answer the questions that follow.

The Burner That Wont Burn You

Weve all done it: cook and serve dinner, then realise hours later that we left the

stove on. Now there is a stove that eliminates the potential danger . Take the pot

off the burner and it automatically turns off after 60 seconds.

B touch

C contact

Question 13

Read the text below carefully and then answer the question that follows.

13 This discovery would lead to the production of

A cloned crops

B artificial crops

C engineering crops

D genetically modified crops

Question 14


Vines have light-sensitive and touch-sensitive hormones. To twine around a branch, the cells on

the side facing away from the branch grow longer, allowing the vine to curl toward the branch.

6

After years of scrutinising Arabidopsis thaliana, a skinny plant in the mustard family,

biologists have found the sequence of chemicals that make up its genetic code. Researchers say

that it is a landmark step towards finding genes that can manipulate and create crops with better

quality.


7/14

14 What enables vines to climb branches?

A Special cells C Touch-sensitive hormones

B Strong vines D Light-sensitive hormones

Question 15


Understanding plant genes can have important effects on medicine for humans. Because many

medicines are derived from plants, manipulating plant genes might produce more powerful

treatments.

B medicines D plant combinations

Question 16


A microchip is a collection of thousands of electrical 16 We can conclude from the text
