These are useful to man in three important ways: They provide him with wood and other products; They give him shade and they help to prevent drought (干旱) and floods.

So unless the government has a great system of control, or can educate the people, the forests slowly disappear.

Passage Three
A man and his wife had a small bar near a station. The bar often stayed open until after midnight, because people came to drink there while they were waiting for trains.
At two o’clock one morning, one man was still sitting at a table in the small bar. He was asleep. The barman’s wife wanted to go to bed. She looked into the bar several times, and each time the man was still there. Then at last she went to her husband and said to him, "You’ve waken that man six times now, George, but he isn’t drinking anything. Why haven’t you sent him away It is very late."
"Oh, no, I don’t want to send him away, "answered her husband with a smile: "You see, whenever I wake him up, he asks for his bill, and when I bring it to him. He pays it. Then he goes to sleep again."
Passage Three
A wise man once said that the only thing necessary for the triumph of evil is for good men to do nothing. So, as a police officer, I have some urgent things to say to good people.
Days after days my men and I struggle to hold back a tidal wave of crime. Something has gone terribly wrong with our once-proud American way of life. It has happened in the area of values. A key ingredient is disappearing, and I think I know what it is: accountability.
Accountability isn’ t hard to define. It means that every person is responsible for his or her actions and liable for their consequences.
Of the many values that hold civilization together—honesty, kindness and so on accountability may be the most important of all. Without it, there can be no respect, no trust, no law and ultimately no society.
My job as a police officer is to impose accountability to people who refuse, or have never learned, to impose it on themselv
A. stricter discipline should be maintained in schools and families
B. more good examples should be set for people to follow
C. more restrictions should be imposed on people' s behavior
D. more people should accept the value of accountability
