　　第二节 (共5小题；每小题2分，满分10分)

　　据短文内容，从短文后选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Dear Mr Ma,

　　Lately our class has become worried about the environment at the back of the school, and we'd like to do something to make it more attractive, We have done some research and have come up with a plan. 36 but we will need a small amount of money for equipment, plants and paint. I am writing to ask the council for permission to do this work and to ask if the school council could donate $500 towards our project.

　　We would like to turn the empty land at the back of the school into a nature garden. We would plant trees and grasses, make paths through the garden and dig a small pond. 37 . It would also attract birds, insects and small animals which students could then study in science classes.

38 .some of our art classes could then paint a huge picture on it. It might be possible to paint over the wall each yearso the next classes can make a new picture.

　　Lastly, we would like to paint all the rubbish bins. At the moment they look old and the paint is coming off (脱落). 39 . We think our plan would greatly improve the back of the school and everyone in the school would benefit. We have already asked our parents and they have promised to donate one weekend of their time to help us complete the project.

　　We hope you will give us permission for this worthwhile project and will be able to donate the $500 we need. When we have finished the work, 40 .

Yours sincerely
