उत्तर

An electrical fan comprises of three blades and a whirling motor. The moment it is switched on. the motor starts and begins to rotate, forcing the blades to move in circular movement. this generates a lot of pressure, which forces the air downwards in all directions.

Listen to an interview between the police inspector in charge of the case, the house­keeper, Ms. Lakshmi and the watchman, Ram Singh. As you listen, note down the details of the burglar.

Inspector:   Hello, madam. I am Inspector Maan Singh. I am in charge of the burglary
case which occurred in the flat of your employer, Mr. Ravikant. It must have
been a harrowing experience for you.
Lakshmi:   Yes, it was a terrible experience. People like that should be locked up in a
prison.
Inspector:   If you will cooperate with us, we will catch them in no time. Were you alone
in the apartment at that time?
Lakshmi:  Yes, it was 11 :30 in the night and I was alone as my master and his wife had
left for Shimla.
Inspector:  How do you think the burglar gained entry into the house?
Lakshmi:  He might have come through the balcony and entered my room.
Inspector:  Now tell me something about his physique. What about his build? How tall
was he?
Lakshmi:   He was about 6 ft tall.
Inspector:   What about his physique?
Lakshmi:   He was not thin. He was well-built and rather plump.
Inspector:   What about his dress? What was he wearing?
Lakshmi:   I think his clothes were rather old and faded. He was wearing a black shirt
which was faded.
Inspector:   Do you remember the colour of his trousers?
Lakshmi:   They were of a dark shade -either black or blue.
Inspector: Can you tell me something about his face?

Lakshmi:   Unfortunately no. When he entered my room I panicked. But then I
gathered courage and screamed and tried to run away. But I was a bit late.
He struck me with a staff and I really don't remember anything after that.
May be I was knocked out.
Later on, I came to know that he broke into the bedroom and ran off with the
jewellery. But Ram Singh, the watchman, who tried to catch him may be
able to describe him better.
Inspector:   OK Lakshmi, thank you! If I need your help I will come again. You may have
to identify the burglar. Now, I will speak to Ram Singh.
Inspector to Ram Singh:
Ram Singh you were on duty and you tried to catch the burglar. You may be
able to give a good description of him. First, tell me about his hair.
Ram Singh:   He had straight black hair.
Inspector:    What about the shape of his face and his complexion?
Ram Singh: He had an oval face with grey eyes and I think he was dark complexioned.
Inspector:   Did he wear spectacles?
Ram Singh:   Yes, with a plastic frame and his nose was rather sharp.
Inspector:   What else can you remember about him? What about his teeth and lips?
Ram Singh:   His lips were quite thick.
Inspector:   Is there anything else that you remember about him?
Ram Singh:   When I heard some noise from inside, I ran in. I tried to stop the burglar and
we had a scuffie. During the struggle I noticed that he had six fingers on his
right hand. But he managed to run away and made good his escape on a
motorbike.
Inspector:   Thank you Ram Singh. We will make sketches on the basis of your
description and nab him.


Some are meet for a maiden's wrist,
Silver and blue as the mountain mist,
Some are flushed like the buds that dream
On the tranquil brow of a woodland stream,
Some are aglow with the bloom that cleaves
To the limpid glory of new born leaves

Some are aglow with the bloom that cleaves

Oh yes, we know it keeps them still,
They don't climb out the window sill,
They never fight or kick or punch,
They leave you free to cook the lunch
And wash the dishes in the sink....
But did you ever stop to think,
To wonder just exactly what
This does to your beloved tot?
IT ROTS THE SENSE IN THE HEAD!
IT KILLS IMAGINATION DEAD!
IT CLOGS AND CLUTTERS UP THE MIND!
IT MAKES A CHILD SO DULL AND BLIND
HE CAN NO LONGER UNDERSTAND
A FANTASY, A FAIRYLAND!
HIS BRAIN BECOMES AS SOFT AS CHEESE!
HIS POWERS OF THINKING RUST AND FREEZE!
HE CANNOT THINK - HE ONLY SEES!

Continuous as the stars that shine
And twinkle on the milky way,

Tossing their heads in springhtly dance.

An old man with steel rimmed spectacles and very dusty clothes sat by the side of the road. There was a pontoon bridge across the river and carts, trucks, and men, women and children were crossing it. The mule-drawn carts staggered up the steep bank from the bridge with soldiers helping push against the spokes of the wheels. The trucks ground up and away heading out of it all and the peasants plodded along in the ankle deep dust. But the old man sat there without moving. He was too tired to go any farther.

The women came out on the shore, and made for the stepping—?stones. They had plenty to laugh and bicker about, as they approached the river in a noisy crowd. They girded up their skirts, so as to jump from stone to stone, and they clanked their sickles and forks together over their shoulders to have ease of movement. They shouted their quarrels above the gush of the river. Noise frightens crocodiles. The big mugger did not move, and all the women crossed in safety to the other bank. Here they had to climb a steep hillside to get at the grass, but all fell to with a will, and sliced away at it wherever there was foothold to be had. Down below them ran the broad river, pouring powerfully out from its deep narrow pools among the cold cliffs and shadows, spreading into warm shallows, lit by kingfishers. Great turtles lived there, and mahseer weighing more than a hundred pounds. Crocodiles too. Sometimes you could see them lying out on those slabs of clay over there, but there were none to be seen at the moment.

I was in for a surprise. When the time came for the broad-jump trials, I was startled to see a tall boy hitting the pit at almost 26 feet on his practice leaps! He turned out to be a German named Luz Long. 1 was told that Hitler hoped to win the jump with him. I guessed that if Long won, it would add some new support to the Nazis’ “master race” (Aryan superiority) theory. After all, I am a Negro. Angr about Hitler’s ways, 1 determined to go out there and really show Der Fuhrer and his master race who was superior and who wasn’t. An angry athlete is an athlete who will make mistakes, as any coach will tell you. I was no exception. On the first of my three qualifying jumps, I leaped from several inches beyond the takeoff board for a foul. On the second jump, I fouled even worse. “Did I come 3,000 miles for this?” I thought bitterly. “To foul out of the trials and make a fool of myself ?” Walking a few yards from the pit, 1 kicked disgustedly at the dirt.

Margot stood alone. She was a very frail girl who looked as if she had been lost in the rain for years and the rain had washed out the blue from her eyes and the red from her mouth and the yellow from her hair. She was an old photograph dusted from an album, whitened away, and if she spoke at all her voice would be a ghost. Now she stood, separate, staring at the rain and the loud wet world beyond the huge glass. “What’re you looking at ?” said William. Margot said nothing. “Speak when you’re spoken to.” He gave her a shove. But she did not move; rather she let herself be moved only by him and nothing else. They edged away from her, they would not look at her. She felt them go away. And this was because she would play no games with them in the echoing tunnels of the underground city. If they tagged her and ran, she stood blinking after them and did not follow. When the class sang songs about happiness and life and games her lips barely moved. Only when they sang about the sun and the summer did her lips move as she watched the drenched windows.
