I have learned English for many years, but I don’t have a chance speak before foreigners. Last week, I happened to meet the foreigner. He needed my help and I felt so exciting.

On Monday, I went to the flowers shop to buy a flower for my friend, because she was ill. I was going to the hospital to see him. In the shop a foreigner and the boss was having a conversation, so the boss didn’t know what the foreigner said. I hesitate for a while, then I came to help the boss. The boss and the foreigner thanked me so many. I felt so happy, because the language when I learn is useful. Since then, I want to learn English well.

【題目】閱讀理解Wilderness
“In wilderness(荒野) is the preservation of the world.” This is a famous saying from a writer regarded as one of the fathers of environmentalism. The frequency with which it is borrowed mirrors a heated debate on environmental protection: whether to place wilderness at the heart of what is to be preserved.
As John Sauven of Greenpeace UK points out, there is a strong appeal in images of the wild, the untouched; more than anything else, they speak of the nature that many people value most dearly. The urge to leave the subject of such images untouched is strong, and the danger exploitation(開發(fā)) brings to such landscapes(景觀) is real. Some of these wildernesses also perform functions that humans need—the rainforests, for example, store carbon in vast quantities. To Mr.Sauven, these ”ecosystem services” far outweigh the gains from exploitation.
Lee Lane, a visiting fellow at the Hudson Institute, takes the opposing view. He acknowledges that wildernesses do provide useful services, such as water conservation. But that is not, he argues, a reason to avoid all human presence, or indeed commercial and industrial exploitation. There are ever more people on the Earth, and they reasonably and rightfully want to have better lives, rather than merely struggle for survival. While the ways of using resources have improved, there is still a growing need for raw materials, and some wildernesses contain them in abundance. If they can be tapped without reducing the services those wildernesses provide, the argument goes, there is no further reason not to do so. Being untouched is not, in itself, a characteristic worth valuing above all others.
I look forwards to seeing these views taken further, and to their being challenged by the other participants. One challenge that suggests itself to me is that both cases need to take on the question of spiritual value a little more directly. And there is a practical question as to whether wildernesses can be exploited without harm.
This is a topic that calls for not only free expression of feelings, but also the guidance of reason. What position wilderness should enjoy in the preservation of the world obviously deserves much more serious thinking.
（1）John Sauven holds that_____.
A.many people value nature too much
B.exploitation of wildernesses is harmful
C.wildernesses provide humans with necessities
D.the urge to develop the ecosystem services is strong
（2）What is the main idea of Para. 3?
A.The exploitation is necessary for the poor people.
B.Wildernesses cannot guarantee better use of raw materials.
C.Useful services of wildernesses are not the reason for no exploitation.
D.All the characteristics concerning the exploitation should be treated equally.
（3）What is the author's attitude towards this debate?
A.Objective.
B.Disapproving.
C.Sceptical.
D.Optimistic.
（4）Which of the following shows the structure of the passage?（CP: Central Point P: Point Sp: Sub-point(次要點) C: Conclusion）
A.
B.
C.
D.

Last Friday I saw the worst weather in years. In the morning, the sun was completely blocked so that I could see something clearly. I stayed at home, look outside. That came into sight was a flash of lightning. Seconds later, the noise of thunder broke the silent. Then a strong wind starts to blow into my room. Pieces of paper on my desk was blown high into the air and some flew out the open window. Then I closed the window when it rained hard and near broke my window.

What a bad weather! I hate it so I can’t go out to play.
