[第四单元];第5小题:B 推断题。从上下文可以推断出萨特想要隐藏这个消息,所以选B,“不公开,不透露”。

44.The automobile has many advantages.Above all, it offers people freedom to go wherever and whenever they want to go.The basic purpose of a motor vehicle is to get from point A to point B as cheaply, quickly, and safely as possible.However, to most people, cars are also personal fantasy machines that serve as symbols of power, success, speed, excitement, and adventure.In addition, much of the world’s economy is built on producing motor vehicles and supplying roads, services, and repairs for those vehicles.Half of the world’s paychecks are auto related.In the United States, one of every six dollars spent and one of every six non-farm jobs are connected to the automobile or related industries, such as oil, steel, rubber, plastics, automobile services, and highway construction.In spite of their advantages, motor vehicles have many harmful effects on human lives and on air, water, land, and wildlife resources.The automobile may be the most destructive machine ever invented.Though we tend to deny it, riding in cars is one of the most dangerous things we do in our daily lives.Since 1885, when Karl Benz built the first automobile, almost 18 million people have been killed by motor vehicles.Every year, cars and trucks worldwide kill an

average of 250,000 people-as many as were killed in the atomic bomb attacks on Hiroshima and Nagasaki-and injure or permanently disable ten million more.Half of the world’s people will be involved in an auto accident at some time during their lives.Since the automobile was introduced, almost three million Americans have been killed on the highways-about twice the number of Americans killed on the battlefield in all U.S.wars.In addition to the tragic loss of life, these accidents cost American society about $60 billion annually in lost income and in insurance, administrative, and legal expenses.Streets that used to be for people are now for cars.Pedestrians and people riding bicycles in the streets are subjected to noise, pollution, stress, and danger.Motor vehicles are the largest source of air pollution, producing a haze of smog over the world’s cities.In the United States, they produce at least 50% of the country’s air pollution.[共5题](1)Besides its basic purpose, Car also serves as a symbol of people’s _________.(A)occupation(B)status(C)character(D)reputation 你选择的答案: 前次作业时已经做对 [正确] 正确答案:B(2)According to the passage, the average number of people killed annually in traffic accidents around the world is __________.(A)60 million(B)250,000(C)3 million(D)18 million 你选择的答案: 前次作业时已经做对 [正确] 正确答案:B(3)A serious environmental problem resulting from automobiles is _________.(A)tragic loss of life(B)traffic jams(C)air pollution(D)mental stress 你选择的答案: 前次作业时已经做对 [正确] 正确答案:C(4)Which of the follow can be inferred from this passage?(A)Automobiles are an important part of the world’s economy.(B)Automobiles are becoming less dangerous.(C)Automobiles will produce less air pollution in the future.(D)Automobiles are killing more people in recent years than in the past.你选择的答案: 前次作业时已经做对 [正确] 正确答案:A(5)The title that suits the passage best is _________.(A)Automobile and Economy(B)Automobile and the Environment(C)The Problems with the Automobile(D)Advantages and Disadvantages of the Automobile 你选择的答案: 前次作业时已经做对 [正确] 正确答案:D 参考答案:

[第四单元];第5小题:D 主旨题。作者以“The automobile has many advantages”开篇,并从运输功能、经济作用等方面说明;然后以“In spite of their advantages, „”引出了汽车带来的负面影响。所以最好的标题是选项D,“汽车的好处和坏处”。

45.I don’t know how I became a writer, but I think it was because of a certain force in me that had to write and that finally burst through and found a channel.My people were of the working class of people.My father, a stone-cutter, was a man with a great respect and veneration for literature.He had a tremendous memory, and he loved poetry, and the poetry that he loved best was naturally of the rhetorical kind that such a man would like.Nevertheless it was good poetry, Hamlet’s Soliloquy, Macbeth, Mark Antony’s “Funeral Oration”, Grey’s “Elegy”, and all the rest of it.I heard it all as a child;I memorized and learned it all.He sent me to college to the state university.The desire to write, which had been strong during all my days in high school, grew stronger still.I was editor of the college paper, the college magazine, etc., and in my last year or two I was a member of a course in playwriting which had just been established there.I wrote several little one-act plays, still thinking I would become a lawyer or a newspaper man, never daring to believe I could seriously become a writer.Then I went to Harvard, wrote some more plays there, became obsessed with the idea that I had to be a playwright, left Harvard, had my plays rejected, and finally in the autumn of 1926, how, why, or in what manner I have never exactly been able to determine.But probably because the force in me that had to write at length sought out its channel, I began to write my first book in London, I was living all alone at that time.I had two rooms-a bedroom and a sitting room-in a litter square in Chelsea in which all the houses had that familiar, smoked brick and cream-yellow-plaster look.[共5题](1)We may conclude, in regard to the author’s development as a writer, that his father _________.(A)made an important contribution

(B)provided him with good education(C)opposed his becoming a writer(D)insisted that he memorize good poetry in order to learn how to be a writer 你选择的答案: 前次作业时已经做对 [正确] 正确答案:A(2)The author believes that he became a writer mostly because of _________.(A)his special talent(B)his father’s teaching(C)his study at Harvard(D)a strong hidden wish within him 你选择的答案: 前次作业时已经做对 [正确] 正确答案:D(3)Which of the following is TRUE about the author?(A)He began to think of becoming a writer at Harvard.(B)He had always been successful in his writing career.(C)He went to Harvard to learn to write plays.(D)He worked as a newspaper man before becoming a writer.你选择的答案: 前次作业时已经做对 [正确] 正确答案:D(4)The author really started on his way to become a writer _________.(A)when he was in high school(B)when he was studying at Harvard(C)when he lived in London(D)after he entered college 你选择的答案: 前次作业时已经做对 [正确] 正确答案:C(5)According to the passage, about the author’s life in 1926 which of the following conclusions CANNOT be safely drawn?(A)He lost the ability to determine in which direction he should go.(B)He was depressed about having his plays rejected.(C)He lived in a house which had smoked brick and cream-yellow-plaster look.(D)He started his first novel.你选择的答案: 前次作业时已经做对 [正确] 正确答案:A 参考答案:

[第四单元];第5小题:A 推断题。从文章最后一段“„left Harvard, had my plays rejected„”可以推断作者对于自己的剧作被拒感到沮丧;从“„in which all the houses had that familiar, smoked brick and cream-yellow-plaster look”可以推断他所居住的房子也是这样的;从“„in the autumn of 1926”以及“I began to write my first book„”

可以推知在1926年作者开始写第一本书。而选项A在文章中是没有根据的。所以选A,“他失去了决定前进方向的能力。”

Many of us would agree.There is, we believe, some connection between having money and feeling fantastic.Most of us would say that, yes, we __(2)__ to be rich.Three in four American college students now consider it is “very important” or “essential” __(3)__ they become “very well off financially”.Money matters.Well, are the rich people happier? Researchers have found that in poor countries, such as Bangladesh, being __(4)__ well off does make for greater well-being.We need food, rest, shelter and __(5)__ contact.But a surprising fact of life is that in countries where everyone can __(6)__ life’s necessities, increasing affluence matters surprisingly little.The correlation __(7)__ wealth and happiness is “surprisingly weak”, observed University of Michigan researcher, Ronald Inglehart, in one 16-nation study of 170,000 people.Once comfortable, more money provides diminishing returns.The

[第四单元];第10小题:B 这里是一个比较级“„ seems less „ than „”。整个句子补充完整是“Happiness seems less a matter of getting what we want than a matter of wanting what we have.”(所谓幸福,与其说是得到我们想要的,还不如说是珍惜我们已有的),故用than。
