[00:38.50]You now have 15 seconds to read Questions 14--16.

[00:46.94]Good evening,ladies and gentlemen,

[00:52.79]today I'm going to show you how to gain high scores at the game BATTLEZONE

[01:01.15]In this game you are in a tank

[01:06.72]and the screen shows your view of the landscape outside.

[01:12.65]You gain points by shooting enemy tanks,super tanks,missiles and saucers.

[01:21.89]Expert players can gain scores of around 150,000 points at this game.

[01:30.44]To get a high score you have to destroy twenty tanks as quickly as possible

[01:39.50]After this the supertanks,missiles and saucers appear

[01:47.55]These are worth far more points than the ordinary tanks.

[01:53.68]However,the number of tanks you have to destroy

[01:59.82]before the supertanks appear varies on different machines.

[02:06.59]Try to approach an enemy tank from the side or the back,

[02:13.43]so it cannot shoot at you.

[02:17.38]Then,when you get close,turn to face it,

[02:23.65]line it up in your sights and fire before it turns to shoot at you.

[02:30.99]If you miss or are too slow,

[02:36.03]quickly escape by moving out of the enemy's line of fire.

[02:42.56]You can then move around the enemy and come in from another side.

[02:49.93]When a supertank appears,try to destroy it as quickly as possible.

[02:57.37]Then wait safely behind an obstacle for a missile or flying saucer

[03:05.73]The cubes are useful objects to hide behind

[03:11.09]as you can fire over them without exposing yourself to danger

[03:17.93]The missiles will fly straight at you,but they are difficult to hit,

[03:25.69]so do not shoot at them until they are quite close.

[03:31.25]The saucers are much easier to hit,

[03:35.90]but do not chase them as you will be open to attack from enemy tanks.

[03:43.03]There are other skills,which I'll come to tomorrow.

[03:49.56]Lots of luck.

[04:31.33]Questions 17--20 are based on the following talk.

[04:38.28]You have 20 seconds to read Questions 17--20.

[04:45.02]Is language a basic human need

[04:50.87]without which a child at a critical period of life

[04:56.41]can be starved and damaged?

[05:00.56]Judging from the experiment of Frederick II in the thirteenth century it may be

[05:08.51]Hoping to discover what language a child would speak

[05:14.25]if he heard no mother tongue,he told the nurses to keep silent.

[05:21.10]All the infants died before the first year.

[05:26.56]Today no such drastic deprivation 1 exists.

[05:33.40]Nevertheless,some children are still backward in speaking.

[05:39.64]Most often the reason is that the mother

[05:44.48]is insensitive to the signals of the infant

[05:49.23]There are critical times when children learn more readily.

[05:55.58]If these sensitive periods are neglected,

[06:01.35]the ideal time for acquiring skills passes

[06:07.10]and they might never be learned so easily again.

[06:12.45]Linguists suggest that speech milestone 2

[06:17.99]is reached in a fixed 3 sequence and at a constant age.

[06:24.16]At twelve weeks a baby smiles and utters vowel 4-like sounds;

[06:31.81]at twelve months he can speak simple words

[06:37.35]and understand simple commands;

[06:41.61]at eighteen months he has a vocabulary of three to fifty words.

[06:48.97]At three he knows about 1000 words which he can put into sentences,

[06:56.63]and at four his language differs from that of his parents in style

[07:03.86]rather than grammar.

[07:06.92]Recent evidence suggests that an infant is born with the capacity to speak

[07:14.08]What is special about Man's brain

[07:19.22]is the complex system which enables a child to connect the sight and feel

[07:26.77]And even more incredible

[07:30.85]is the young brain's ability to pick out an order in language

[07:37.09]from the hubbub 5 of sound around him,to analyze 6,

[07:43.23]to combine and recombine the parts of a language in novel ways.

[07:50.47]But speech has to be triggered,

[07:55.12]and this depends on interaction between the mother and the child.

[08:01.28]Insensitivity of the mother dulls the interaction because the child

[08:09.04]gets discouraged and sends out only the obvious signals.

[08:15.67]Sensitivity to the child's non-verbal cues

[08:21.24]is essential to the growth and development of language.

[08:43.05](A)The child's brain was damaged   (B)The child died

[08:47.60](C)The child kept silent    (D)The child heard no mother tongue

[08:49.66]18.Why are some children still backward in speaking?

[08:51.77](A)Their brains have to absorb too much language at once.

[08:53.81](B)They do not listen carefully to their mothers.

[08:55.85](C)Their mothers are not intelligent enough to help them.

[08:57.89](D)Their mothers do not respond to their attempts to speak.

[09:03.82]19.What is the difference of the language of a child

[09:05.85]of four from that of his parents?

[09:10.50](A)The vowel sounds   (B)The grammar  (D)The vocabulary

[09:15.36]20.What is a possible consequence

[09:20.40]if the mother does not respond to her child's signals?

[09:24.74](A)The child will make little effort to speak.

[09:26.80](B)the child will never be able to speak properly.

[09:28.82](C)the child will stop giving out signals.

[09:33.15](D)the child will invent a language of its own,

[09:33.22]Questions 21-- 24 are based on the following talk.

[09:40.15]You now have 20 seconds to read Questions 21-- 24.

[09:48.09]It has often been remarked that the saddest thing about youth

[09:56.13]is that it is wasted on the young,

[10:00.71]According to a recent survey,today's college freshmen 7 are "more materialistic 8

[10:09.14]and less considerate of others"

[10:13.71]than at anytime in the 19 years of the poll.

[10:19.64]The survey disclosed what I had already suspected from informal polls:

[10:27.09]if it (whatever it may be) won't compute,and you can't drink it,

[10:34.93]smoke it or spend it,then "it" holds little value.

[10:41.38]Not surprising in these hard times,

[10:46.52]the student's major objective is "to be financially well off."

[10:53.47]Less important than ever is developing a meaningful philosophy of life."

[11:01.02]It follows then that today

[11:05.78]the most popular is not literature or history but accounting 9.

[11:13.04]Interest in teaching and social service is at a low,

[11:19.57]along with ethnic 10 and women's studies.

[11:24.40]On the other hand,enrolment in business programs,

[11:30.07]engineering and computer science is way up.

[11:35.22]That's no surprise either.

[11:39.76]A friend of mine was a sales representative for a chemical company.

[11:46.61]And she was making twice the salary of her college instructors 11

[11:53.74]her first years on the job

[11:57.99]--even before she completed her two-year associate degree.

[12:04.16]"I'll tell them what they can do with their music,

[12:09.51]history,literature,or whatever,"she was fond of saying.

[12:15.97]And that was four years ago;

[12:20.12]I shudder 12 to think what she's earning now.

[12:25.16]Frankly,I'm proud of the young lady,

[12:30.62]though not her attitude but her success.

[12:36.06]But why can't we have it both ways?

[12:40.71]Can't we educate people for life as well as for a career?

[12:47.16]In a time of increasing specialization,

[12:53.51]more than ever we need to teach young people what is truly important in life

[13:00.45]Oscar Wilde had it right

[13:05.00]when he said that we ought to give our ability to our work

[13:10.95]but our genius to our lives.
