a) Many of our young people spend more time in their classroom than before TV sets.
b) Teenagers are considerably influenced by the electronic media.
c) The television has become the single most powerful influence in their lives.

Ans : a)False b)True c) True d)True. Students should write given statements also.
We often hear this statement that’ many of our young people spend more time before their TV sets, than they do in their classrooms or with their textbooks. : A bit exaggerated though it may sound, it is nearly true and our teenagers are being considerably influenced by the electronic media, particularly the TV. The television has become the single most powerful influence in the lives of many of our youngsters today. Too often this happens to us much before we realize it ourselves. I am in no way trying to deny the many advantages of TV, or minimize its manifold contributions to our world. On the other hand, I consider, TV as one of the greatest scientific achievements of our times,bringing people closer than ever before. Television’s use of the modern satellite technology brings today even the remotest regions of the world to us in seconds, making the world a small (global) village. As we know, television also provides us with a fuller and more impressive coverage of current events than any other media. The TV does serve, in addition, as a medium of education as well as entertainment. Besides helping us to learn subjects taught in school, college in greater depth, it enables us (National Geographic, Discovery channel etc.) to see and appreciate from close quarters (without having to go there, which is very expensive or even impossible for most of us) the wonders of God’s creation in any part of the world.

Q.5 (A) Read the following extract carefully and complete the activities : (4M)
I was walking around the camp, around the barracks, near the barbed wire fence where the guards could not easily see. I was alone.
On the other side of the fence, I spotted someone: a little girl with light, almost luminous curls. She was half- hidden behind a birch tree. I glanced around to make sure no one saw me. I called to her softly in German, “Do you have something to eat?” She didn’t understand. I inched closer to the fence and repeated the question in Polish. She stepped forward. I was thin and gaunt, with rags wrapped around my feet, but the girl looked unafraid. In her eyes I saw life. She pulled an apple from her woolen jacket and threw it over fence. I grabbed the fruit and, as I started to run away, I heard her say faintly, “I’ll see you tomorrow.” I returned to the same spot by the fence at the same time every day. She was always there with something for me to eat – a hunk of bread or better yet, an apple. We didn’t dare speak or linger. To be caught would mean death for us, both. I didn’t know anything about her. Just a kind farm girl, except that she understand Polish.
What was her name? Why was she risking her life for me?

(B) Read the following extract carefully and complete the activities: (4M)
George : (contemptuously) I wasn’t afraid of the bulldog.
Tom : No, may be you weren’t; but I’m not sure that the savage beast hasn’t torn
off a bit of young Alfie’s suit, and if he has there won’t half be a row!
(Alfie fidgets nervously at the mention of his damaged suit)
Tom : (down R.C.) How much money have we collected?
Ginger : (crossing C. to George) let’s have a look under the light.
(after counting coppers, with the aid of George’s torch) Eight pence half penny.
Tom : (in a tone of disgust) only eight pence half penny – between four of us – after yelling
our heads off all the evening! Crikey! Money’s a bit tight round these parts, isn’t it?
George : I told you it was too early for carol-singing. It’s too soon after Guy Fawke’s day.
(Faint distant scream off R.)
Tom : (startled) What was that?
George : What was what?
Tom : That noise – it sounded like a scream.
George : Nonsense.
Alfie : (L) Let’s go home.
George : You chaps do get scared easily. It wouldn’t do for you to be in the club that Bert
Williams and I are running. We go out looking for adventures like this.
Ginger : Club? I thought it was a gang.
George : Gangs are getting too common. We have tuned ours into a club – “The Do and Dare Club” we call it and no one in it must ever show a sign of fear.
Tom : I shouldn’t think you’d have many members. Why, everybody’s afraid of something – if
it’s not one thing, it’s bounded to be another.
George : (in a very superior tone) Ours isn’t a club for kids; it’s for daring young fellows keen on
adventure.
