一、语法选择(共15小题,每小题1分,共15分)
阅读下面的短文,按照句子结构的语法性和上下文连贯的要求，从1-15各题所给出的A,B,C,D四个选项中选出最佳选项。
In the 13th century, the famous Italian traveler, Marco Polo, 1 a long way to China. During his stay in China, he saw many 2 things. One of the things he discovered was that the Chinese used paper money. In western countries, people did not use paper money 3 the 15th century. 4 , people in China began to use paper money in the 7th century.
A Chinese man 5 Cai Lun invented paper almost 2,000 years ago. He made paper 6 wood. He then put all the paper together and made the paper 7 a book.
Now we still use wood to make paper. We use a lot of paper every day. If we keep on 8 so much paper, there will not be any trees left on the earth. If 9 no trees, there will be no paper. Every day, people 10 about 2,800 tons of paper. We use 17 trees 11 one ton of paper. This means we are cutting nearly 48,000 trees every day.
Since it 12 more than 10 years for a tree to grow, we must start using 13 paper now. So how can we save paper We can use both sides of 14 of paper, especially when we are making notes. We can choose drinks in bottles instead of those in paper packets. We can also use cotton handkerchiefs (手帕) but not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant gives us a paper bag, we can save it and reuse it later.
Everyone can help to save paper. If we all think carefully, we can help 15 trees. But we should do it now, before it is too late.

六、书面表达One possible version:
Boys and girls,
As we all know, trees are very important to the environment. In many ways they help us live better. They provide us with food and raw materials. They keep the air clean, and they stop the soil from washing away. What’s more, trees can prevent the climate from getting warmer.
But more and more trees are disappearing around the world every year, mainly because people cut down them for the use of farming and construction. Trees promise us a good life. So, in order to have a better future, we should plant more trees and take care of them. That’s why we hold the activity called “Planting Trees for the Earth”. Let’s together join in it!
