When we see well, we do not think about our eyes very often. (79) It is only when we cannot see perfectly that we realize how important our eyes are.

People who are nearsighted can only see things that are very close to their eyes. Everything else seems blurry (模糊的). Many people who do a lot of close work, such as writing, reading and sewing, become nearsighted. Then they have to wear glasses in order to see distant objects clearly.

People who are farsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.

Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people olden became blind. Now, however, it is possible to operate on the cataracts and remove them.

Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at object out of one eye; then look at the same object out of your other eye. You will find the object's relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.

We should take good care of our eyes ______.

A.only when we can see well

B.only when we cannot see perfectly

C.even if we can see dell

D.only when we realize how important our eyes are

Passage Two

When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.

People who are nearsighted can only see things that are very close to their eyes. Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly'.

People who are nearsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.

Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

听力原文:M: Good morning everyone. Well I think we can start straightaway by getting Rosie
to do her presentation. Would you like to start, Rosie?

W: Yes, well, um, we've done a survey on local entertainment. Basically, we tried to find out how students feel about the entertainment in the town and how much they use it. So we've called our project "Out and About"...

M: Yes, that's a good title!

W: We wanted to find out how well students use the entertainment facilities in town... whether they get to see the latest plays, films... that kind of thing. Actually there were a lot of areas to choose from but in the end we limited ourselves to looking at two general categories: cinema and theatre.

M: Right.

W: OK. Well, first of all the cinema. In the town, there are three main places where you can see films. There's the new multi-screen cinema complex, the old park cinema, and a late-night odeon. In terms of audience size, the multi-screen complex accounts for 75% of all cinema seats, the park cinema accounts for 20% of seats and the late-night odeon has just 5% of seats.

M: Yes, as is shown in your chart.

W: As you probably know, the complex and the park show all the latest films, while the late-night cinema tends to show cult films. So, when we interviewed the students, we thought the complex would be the most popular choice of cinema... but surprisingly it was the late-night odeon. Most students said that if they wanted to see a film, they waited for it to show at the park because the complex is more expensive and further out of town so you have to pay more to get there as well.

M: Yes, and that adds to the cost, of course, and distracts from the popularity, evidently.

W: Well, next, we looked at theatres. There's the Stage Theatre in town, which is very old and architecturally quite beautiful. And there's also the large, modem theatre, the Ashtop, that has recently been built. But the thing about the theatres is that there's a whole variety of seat prices. Also, the types of performance vary... so students tend to buy seats at both and like using both for different reasons and if they want cheap seats at the Ashtop, they can just sit further from the front.

M: And anything else?

W: Yes. What we did find that was very interesting is that there are periods during the year when students seem to go to the theatre and periods when they go to the cinema and we really think that's to do with the budget. There's a peak around November and December when they go to the theatre more and then a period in April and May when neither is particularly popular and then theatre viewing seems to tail off virtually while the cinema becomes quite popular in June and July.

M: Mmm. I think you're probably right about your conclusions...

(23)

A.The entertainment on campus.

B.The entertainment facilities students use in town.

C.The kinds of films and plays students enjoy.

D.The cinemas and theatres students like to go to.

听力原文:Tutor: Good morning everyone. Well I think we can start straightaway by getting R
osie and Mike to do their presentation. Would you like to start, Rosie?

Rosie: Yes, well, um, we've done a survey on local entertainment. Basically, we tried to find out how students feel about the entertainment in the town and how much they use it.

Mike: Yes, so we've called our project 'Out and About' ...

Tutor: Yes, that's a good title! 'Out and About'.

Rosie: We wanted to find out how well students use the entertainment facilities in town ... whether they get to see the latest plays, films ... that kind of thing.

Tutor: Now, we have our own facilities on campus of course ...

Rosie: Oh, yes, we deliberately omitted those as we really wanted to examine outside entertainment in the town as opposed to on the university campus.

Mike: Actually there were a lot of areas to choose from but in the end we limited ourselves to looking at three general categories: cinema, theatre and music.

Tutor: Right.

Rosie: OK. Well, er... first of all cinema. In the town, there are three main places where you can see films. There's the new multi-screen cinema complex, the old Park cinema, and a late-night Odeon.

Mike: So if you look at this chart ... in terms of audience size, the multi-screen complex accounts for 75% of all cinema seats, the Park Cinema, accounts for 20% of seats and the late-night Odeon has just 5% of seats.

Rosie: As you probably know, the complex and the Park show all the latest films, while the late-night cinema tends to show cult films. So, when we interviewed the students, we thought the complex would be the most popular choice of cinema...but surprisingly it was the late-night Odeon.

Mike: Yeah, and most students said that if they wanted to see a new film, they waited for it to show at the Park because the complex is more expensive and further out of town so you have to pay more to get there as well.

Tutor: Yes, and that adds to the cost, of course, and detracts from the popularity, evidently.

Rosie: Well, next, we looked at theatres. The results here were interesting because, as you know, there's a theatre on campus, which is popular. But there's also the Stage Theatre in town, which is very old and architecturally quite beautiful. And there's the large, modern theatre, the Ashtop, that has recently been built.

Tutor: So you just looked at the two theatres in town?

Mike: Yes. But the thing about the theatres is that there's a whole variety of seat prices. Also, the types of performance vary ... so students tend to buy seats at both and like using both for different reasons and if they want cheap seats at the Ashtop, they can just sit further from the front.

Rosie: What we did find that was very interesting is that there are periods during the year when students seem to go to the theatre and periods when they go to the cinema and we really think that's to do with budget. If you look at this graph, you can see that um, there's a peak around November/December when they go to the theatre more and then a period in April/May when neither is particularly popular and then theatreer viewing seems to trail off virtually while the cinema becomes quite popular in June/July.

Tutor: Mmm. I think you're probably right about your conclusions ...

Mike: Well, lastly we looked at music. And this time we were really investigating the sort of small music clubs that offer things like folk or specialise in local bands.

Tutor: So not musicals as such ...

Mike: That's right.

Rosie: We looked at three small music venues and we examined the quality of the entertainment and the venue and gave a ranking for these: a cross meaning that the quality was poor, a tick meaning it was OK and two ticks for excellent. First of all, The Blues Club, which obviously specialises in blues music. This was a pretty small place and the seating was minimal so we didn't give that a very good rating.

Mike: No! We don
