题型：多项选择题 阅读下列材料，从所给的A、B、C、D四个选项中选出符合1-4小题要求的最佳选项。 Tom, Eric, Tess and Ann are talking about in what way they would like their schools improved. Read the following descriptions (A, B, C and D) and match them with the four opinions marked 1-4. ( )1. Tom: I'd like somewhere to sit and read and enjoy myself. ( )2. Eric: I hope our school can be more comfortable and convenient. ( )3. Tess: I really prefer to have a place to do some exercise after class. ( )4. Ann: I think our school should buy more equipment like computers. A Our school is big with nice modern buildings and everything, but there is one thing I would really love-a gym. We're right in the middle of a big city and the traffic is very busy, so I find it very difficult to get out to the gym at lunchtime, A gym would be good for the school. If more people went to the gym and did some exercise, they'd probably work better! B What I'd most like to have is a little cafe, where we students can rest and do some reading. At the moment people have to stand in the passage, or even outside and there's nowhere to buy a drink or something, or read the paper, so people don't stay in school for long after the lessons finish. I think it would be completely different if they had somewhere to enjoy themselves. C Our school has a nice building, and is in a nice part of the city. Unfortunately we haven't got much equipment, so I'd really like to have a computer room with the Internet available. I think students can learn a lot this way. And I'd like to have VCDs in every classroom instead of tapes. VCDs are so much more interesting for learning a language, I think. D Our school is just uncomfortable in every way. For example, the chairs are really uncomfortable, so the next thing I'd like to do is get some comfortable chairs of good quality. Oh, and the worst thing is that we're on the fifth and sixth floors of our building, so I'd love to have some lifts put in. Just one little lift would make our lives so much easier! 查看答案
