DELHI PUBLIC SCHOOL, BHILAI (C.G.)

Time: 1.30 hrs. PRE MID-TERM EXAMINATION 17.07.18

Class: X ENGLISH COMMUNICATIVE M.M:40

SECTION-A [READING] [8]

1. Read the passage carefully and answer the questions that follow: (8 1=8)

1. Handwriting is the writing created by a person with a writing utensil such as a pen or a

pencil. It is interesting to note that each person‟s handwriting is unique and is used in fields

like medicine, psychology, criminology and personality development etc. Furthermore, the

deterioration of a person‟s handwriting is also a symptom or result of certain diseases while a

good one shows sound health.

2. Handwriting is the index of mind and even personality. It aids presentation especially during

student life and then as one of the remarkable qualities throughout our professional life.

However, it is saddening to note that two important aspects of education namely drawing and

handwriting are losing their grip now. Why? Because children prefer to take „snaps‟ and

„text‟ messages in place of them, thanks to our Hi-tech world.

3. Now, let us talk of some famous personalities and their handwriting. It is surprising that the

science of graphology of handwriting analysis reveals every facet of the writer‟s

personality-level of integrity, physical and mental health and even intelligence. While

analysts say that Barack Obama exudes grace, fluidity, charm and wit in his handwriting,

Putin is very fast and restless. Both of them however, exhibit remarkable leadership qualities

in their own ways as is evident from their unique writing styles. Interestingly, the father of

our nation, Mohandas Karam Chand Gandhi was always worried for his poor handwriting.

4. However, trends are changing fast. Now, in today‟s “do-it-yourself” and “get-it-done fast”

world, handwriting has become less important. Still, clarity of words, organization, proper

spacing, paragraph structuring are some important characteristics of a good handwriting.

Whether a person is fidgety, stable balanced, reckless, isolationist or social, this all is shown

by the handwriting. So next time, when you write something, scatter pearls on your notebook;

use quality writing utensils; focus on your metholodgy and indent in writing. I am sure you

are going to be happy.

(a) Why have drawing and handwriting become less important these days?

(b) Enlist two fields in which handwriting becomes a part of study and research.

(c) How is handwriting related with the health of an individual?

(d) Whose handwriting is more presentable, Putin or Obama? Justify your answer.

(e) What does handwriting reveal about an individual‟s personality?

(f) How has the author described today‟s world in the last paragraph?

(g) Find the word from the 1st para which means degradation or disintegration.

(h) Find the word from the passage which mean the same as „distinctive‟. (para 3)

SECTION-B [WRITING AND GRAMMAR] [20]

2. You have observed that modern lifestyles in cities have made people follow the principle „Late to

sleep and late to rise‟ instead of the other way round. As you understand the harm to a person‟s

health due to this, write a letter to the Editor of a national daily making people aware of the

problems that arise. Use ideas from the MCB unit on „Health and Medicine‟. You are Noor/Niket

of 106, Karol Bagh, Delhi. (100-120 words) (8)
