ATOMIC ENERGY EDUCATION SOCIETY HALF-YEARLY EXAMINATION (2018-19)

CLASS: VIII DATE OF EXAM: 26-09-18 TIME: 3 HOURS SUBJECT: ENGLISH MARKS: 80 ----------------------------------------------------------------------------------------------------------------

General Instructions:

This paper contains four sections.

Section A-Reading 20

Section B- Writing 20

Section C- Grammar 15

Section D- Literature 25

All questions are compulsory.

SECTION - A (READING)

Q1. Read the following passage and answer the questions that follow.

WATER: LIFE’S MAIN SOURCE

Man does not live by food alone. Water is vital to human health and fitness. Although it is not

a nutrient per se as are carbohydrates, fats, proteins, vitamins and minerals. It, in fact, is a key

nutrient in as much as no life is possible without it. Whereas we can do for weeks without

food , we cannot live without water longer than a couple of days.

Water approximates 60 per cent of the body weight of human adults. The total amount of

water in a man weighing 70 kilograms is approximately a little over 40 litres.It is an excellent

solvent-more substances are soluble in water than in any other liquid known so far. This

makes it an ideal constituent of the body fluids which sustain life supporting chemical

reactions. It dissolves varied products of digestion and transports them to the rest of the body.

Likewise, it dissolves diverse metabolic wastes and helps drain them out of the body.

Besides, it performs variety of functions-some well-known and well understood while other

not so well appreciated yet vital. The no less important role of water is to distribute/dissipate

the body heat efficiently, thereby regulating body‟s temperature. Water accomplishes this

role ideally because it has high thermal conductivity ensuring rapid heat transfer from one

part to the other.

Above all, water has a high specific heat, implying that it takes a lot of heat to raise the

temperature of water and likewise much heat must be lost to lower its temperature.

Drinking a lot of water is an inexpensive way to stay healthy. Even excess of water is

harmless. Water therapy-drinking a litre or so the first thing in the morning is kidney-

friendly.

The water regulation in the body is affected by hypothalamus in two ways

i e., (i) by creating the sensation of thirst which makes us drink water and

(ii) by controlling the excretion of water as urine. If water regulation fails, medical

emergency ensues.

Q.2 Read the following passage carefully and answer the questions that follow.

BLUE WHALES ---THE LARGEST ANIMALS

Blue whales are the largest of animals known, either living or extinct. About six metres long

at birth, they grow rapidly-at peak rates they can gain up to three kilos in an hour and

consume up to 90 kilos a day of fat-rich breast milk to reach up to 30 metres on maturity.

Their social grouping is usually small, involving only pairs or a few individuals. They have

no vocal cords, so their repetitive moaning, rumbling calls are made by vibrating nasal air

sacs-a bit like the sound made when humans snore or blow their noses. Their calls are of

such low frequency that they‟re mostly inaudible to human ears, but they can reach188

decibels (far louder than a screaming jet engine or even rock music at peak intensity) and

can be detected up to 400 kilometres away.

Despite its incredible size, few people have ever seen a blue whale. Official records show a

mere 35 sightings in Australian waters between 1887 and 1999. Whaling is the reason:

species after species were drastically over-hunted. Hump-back whales, blue whales, fin

whales, sei whales and minke whales were targeted in turn as catches declined. Official

estimates are that the original Southern Hemisphere blue whale population was once about

225,000 but only a few thousand remain.

The tell-tale burst of white spray cannons nine metres into the air when the whales exhale

from twin blowholes atop their heads. Blue whales feed almost exclusively on swarms of

krill, tiny prawns-like animals, scooping up several tonnes a day.

In one mighty mouthful these animals swallow as much as 50 cubic meters of water. It will

slowly force all that water out through the baleen plates—stiff, feathery combs attached to its

upper jaw. The plates filter out the thousands of krill it has just taken in with all that water.

Then it will scrape off the krill with its tongue and that‟s breakfast, lunch and dinner for a

blue whale.

Blue whales are still highly vulnerable. Large-scale commercial krill harvesting would

deplete their sole food supply. Many blues must also deal with busy shipping traffic and other

underwater noise issues like marine seismic exploration for oil and gas and navy sonar and

submarine testing.

Page 3 of 6

Whales rely heavily on sound to communicate at great distances and experts fear that noise

pollution might disrupt whale social interactions, damage their sensitive ears or drive them

away from vital feeding and breeding grounds.
