The reason is that rich volcanic soil makes the land fantastic for farming. By growing and selling a variety of crops, local people earn a good living. For them, the economic benefit they get is far more than the risk of dying or losing property in one of the volcano’s frequent eruptions.People everywhere make decisions about risky situations this way. That is, by comparing the risks and the benefits. According to the experts, the side of the risk depends on both its probability and seriousness. Let’s take Mount Etna for example. It does erupt frequently, b ut those eruptions are usually minor. So the overall risk for people living nearby is relativelysmall. But suppose Mount Etna erupted every day, or imagine that each eruption there killed thousands of people. If that were the case, the risk would be much larger. Indeed, the risk would be too large for many people to live with. And they would have to move away.68.Why is the area surrounding Mount Etna in Italy densely populated?A.Because the active volcano is a grand view.B.Because people there like taking risks.C.Because the volcanic soil is excellent for farming.D.Because they earn a good living by witnessing the volcano’s frequent eruptions.69.What do we know about Mount Etna from the passage?A.One of Etna’s recent eruptions made many people move away.B.Etna’s fre quent eruptions have ruined most of the local farmland.C.Etna’s eruptions are frequent but usually mild.D.There are signs that Etna will erupt again in the near future.70. What will people living near Mount Etna do in the face of its eruptions?A.They will remain where they are.B.They will leave this area forever.C.They will turn to experts for advice.D.They will seek shelter in nearby regions.71. How do people make decisions about risky situations?A.By judging to what extent they can get rid of the risks.B.By estimating the possible loss of lives and property.C.By estimating the frequency of volcanic eruptions.D.By judging the possible risks against the likely benefits.(C)When I was about 12, I had an enemy, a girl who liked to point out my shortcomings. Week by week her list grew: I was very thin, I wasn’t a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.He listened to me quietly, and then he asked. ―Are the things she says true or not? Janet, didn’t you ever wonder what you’re really like? Well, you now have that girl’s opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.‖I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn’t change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I got a fairly clear picture of myself.I brought the list back to Daddy. He refused to take it. ―That’s just for you,‖ he said. ―You know better than anyone else the tru th about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you’ll find it will be of help to you. Our world is full of people who think they know yourduty. Don’t shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.‖Daddy’s advice has returned to me at many important moments. In my life, I’ve never had a better piece of advice.72. Which do you think would be the best title for this passage?A. Not an Enemy, but the Best FriendB. The Best Advice I’ve Ever HadC. My FatherD. My Childhood73. What does ―Week by week her list grew‖ mean?A. Week by week she discovered more shortcomings of mine and pointed them out to me.B. She had made a list of my shortcomings and she kept on adding new ones to it so thatit was growing longer and longer.C. I was having more and more shortcomings as time went on.D. Week by week, my shortcomings grew more serious.74. Why did her father listen to her quietly?A. Because he believed that what her daughter’s ―enemy‖ said was mostly true.B. Because he had been so angry with his daughter’s shortcomings that he wanted toshow this by keeping silent for a while.C. Because he knew that his daughter would not listen to him at that moment.D. Because he wasn’t quite sure which girl was telling the truth.75. What did the father do after he had heard his daughter’s complaint?A. He told her not to pay any attention to what her ―enemy‖ had said.B. He criticized her and told her to overcome her shortcomings.C. He told her to write down all that her ―enemy‖ had said about her and pay attentiononly to the things that were true.D. He refused to take the list and have a look at it.(D)According to a published poll (民意调查), blacks and whites both think that crime and the breakdown of the family are two of America’s biggest problems, but disagree when it comes to recognizing causes and solutions.While 53 percent of blacks thought that financial pressure on families was the main cause of society’s life, 58 percent of white s blamed moral decline.
