Professor Martin's report says that children who attend a number of different schools, because their parents have to move around the country, probably make slow progress in their studies. There are also signs, says Professor Martin, that an unusually large number of such children are mentally affected.

　　The professor says, "It's true, my personal feeling is that children should stay in one school. However, our findings are based on research and not on any personal feelings that I or my assistants may have on the subject."

　　Captain Thomas James, an Army lecturer for the past 20 years and him self a father of two, said," I've never heard such rubbish. Taking me for ex ample, no harm is done to the education of my children who change schools regularly－if they keep to the same system, as in our army schools. In my experience, I've known quite a few of them－Army children are as well－adjusted（调整）as any others, if not more so. What the professor doesn't appear to appreciate is the fact that in such situations children will adapt（适应）much better than grown-ups."

　　When this was put to Professor Martin, he said that at no time had his team suggested that all such children were backward or mentally affected in some way, but simply that in their experience there was a clear tendency（倾向）.

　　"Our findings show that while the very bright child can deal with regular changes without harming his or her general progress in studies, the majority of children suffer from constantly having to enter a new learning situation."

　　1．According to this passage, Professor Martin's personal feeling_______.

　　　　A. is the opposite of what his report has shown

　　　　B. is in a way supported by his research

　　　　C. has played a big part in his research

　　　　D. is based on his own experience as a child

　　　　A. have been affected by changing schools

　　　　B. go to ordinary State schools

　　　　C. can get used to the Army school education

　　　　D. discuss their education regularly with their father

Washington — The largest ozone (臭氧)hole ever observed has opened up over Antarctica, according to the scientists of the US National Aeronautics and Space Administration (NASA). They believe it is a sign that ozone — destroying gases produced years ago are just now causing the largest quantities of ozone to disappear.

　　This year’s South Pole ozone hole spreads over about 28.5 million square kilometers, an area three times larger than the landmass of the United States.

　　Pictures of the hole have been offered by NASA. The hole appears as a giant blue mass, totally covering Antarctica and stretching to the southern tip of South America.

　　“The last time the ozone hole was close to this size was in 1998, when it spread over about 27.2 million square kilometers,” NASA said.

　　Paul Newman, who works with NASA’s Total Ozone Mapping Spectrometer (TOMS) instrument on a NASA satellite, said ozone watchers had expected a big hole this year, but not this big.

　　The Antarctica ozone hole, first observed in 1985, is caused by the depletion (损耗) of Earth protecting ozone by human-made chemicals such as chlorofluorocarbons, known as CFCs.

　　“Even though these chemicals were not allowed to use from the beginning of 1987, they remain in the atmosphere and will continue to do so for years,” Newman said.

　　“This year’s large hole may have been caused by a change in a swirling high-level air current over Antarctica, which circles the area and contains the zone hole,” Newman said.

56. The text is mainly about ____ .

　 A. the discovery of the largest ozone hole           B. the discovery of the Antarctica ozone hole

　 C. the history of the Antarctica ozone hole          D. the size of the largest ozone hole

57. The time 1985 was talked about in the text because it was when the Antarctica ozone hole ____ .

　 A. was watched by Newman   B. was first closed   C. disappeared   　 D. was first watched

58. There is a giant ozone hole over Antarctica because ____ over there.

　 A. human-made chemicals have protected ozone     B. ozone has protected the earth

　 C. human-made chemicals have destroyed ozone     D. human-made chemicals have increased ozone

阅读下列短文，从每题所给的四个选项(A、B、C、D)中，选出最佳选项。

　　Besides this question of the time given to pronunciation，there are two other requirements for the teacher：the first，knowledge；the second，technique．

　　It is important that the teacher should be in possession of the necessary information．This can generally be go form books．It is possible to get from books some idea of the speech；and of what we call general phonetic rules．It is also possible in this way to get a clear mental picture of the relationship between the sounds of different languages，between the speech habits of English people and those，of your students．Unless the teacher has such a picture，any explanations he makes on his students'pronunciation are unlikely to be of much use，and lesson time spent on Pronunciation may well be wasted．

　　But it does not follow that you can teach pronunciation successfully as soon as you have read the necessary books．It depends，after that，what use you make of your knowledge；and this is a matter of technique．

　　Now the first and most important part of a language teacher's technique is his own performance，his ability to show off the spoken language，in every detail of sound as well as in fluent speaking，so that the student's ability for imitation is given the fullest space and encouragement．The teacher，then，should be as perfect a model in this field as he can make himself．And to make his own performance better，however satisfactory this may be，the modern teacher has in his hand recordings and a radio，to supply the real voices of native speakers，or，if the teacher happens to be a native speaker himself，or speaks just like one，then to change the method of presenting the language material．

　　However，the process of showing pronunciation，whether by personal ex-ample or with the help of machines，is only the beginning of teaching pronunciation．The technique of teaching each sound also needs to be considered．

1．How might the teacher find himself wasting lesson time？

[　　]

A．By spending lesson time on pronunciation．

B．Bu making ill-informed explanations upon pronunciation．

C．By not using books on phonetics in the classroom．

D．By not giving students a clear mental picture of the difference between

sounds．

2．Students have an ability for imitation which is________．

[　　]

A．plain and obvious

B．well developed

C．not yet developed

D．too weak to be useful

3．What is the main point the author makes about imitation of the teacher？

[　　]

A．It is a matter of secondary importance．

B．Students should be given every chance for it．

C．It depends on the student's ability．

D．Teachers are perfect models for students to imitate．

4．TO Someone teaching his own language to foreigners mechanical aids can________．

[　　]

A．improve his own performance

B．replace his own performance

C．provide examples of native speech

D．make his voice louder

5．Showing pronunciation is to be regarded as ________．

[　　]

A．a part of teaching pronunciation

B．an exercise of value in itself

C．an example of the use of mechanical aids

D．a technique for teaching separate sounds
