题目列表(包括答案和解析)
It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself. It is part of a system in which all forms of life are joined together. If we change one part of the nature order, this will almost certainly bring about changes in some other parts.
The cutting of forests reduced the supply of oxygen. The killing of weeds and insects by chemicals led to the wide-spread poisoning of animals and birds. The throwing of waste products into the ocean hurt life in the sea, while waste gases changed the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.
And so we could go on adding more examples until in despair(绝望) we might feel like giving up the struggle to control these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself because of his silly action.

There's a man in the habit of hitting me on the head with an umbrella.At first I couldn't stand it；now I'm used to it.
I don't know his name.I know he's average in appearance，wears a gray suit，and has a common face.One hot morning，when I was sitting on a tree?shaded bench in Palermo Park，reading the paper，suddenly I felt something touch my head.It was the very same man who now，as I'm writing，keeps striking me with an umbrella.
On that occasion I turned around filled with anger.He just kept on hitting me.I asked him if he was crazy.He didn't even seem to hear me.Then I threatened to call a policeman.Calmly，cool as a cucumber，he stuck with his task.After a few moments of hesitation，and seeing that he was not about to change his attitude，I stood up and hit him on the nose.The man fell down.But he immediately got back on his feet，obviously with great effort，and without a word again began hitting me on the head with the umbrella.His nose was bleeding and，at that moment，I felt sorry for him.I felt regret for having hit him so hard.After all，the man wasn't exactly hitting me；he was merely tapping me lightly with his umbrella，not causing any pain at all.Of course，those taps were extremely bothersome.As we all know，when a fly lands on your forehead，you don't feel any pain；what you feel is annoyance.Well then，that umbrella was one huge fly that kept landing on my head time after time.
Convinced that I was dealing with a madman，I tried to escape.But the man followed me，wordlessly continuing to hit me.So I began to run(I should point out many people run as fast as I do)．He took off after me，trying to land a blow.The man was out of breath so that I thought，if I continued to force him to run at that speed，he would drop dead right then and there.
