题目内容
Generations of Americans have been brought up to believe that a good breakfast is essential to one’s life. Eating breakfast at the start of the day, we have been told, and told again, is as necessary as putting gasoline in the family car before starting a trip.
But for many people, the thought of food as the first thing in the morning is never a pleasure. So in spite of all the efforts, they still take no breakfast. Between 1977 and 1983, the latest year for which figures could be obtained(可获得的), the number of people who didn’t have breakfast increased by 33%—from 8.8 million to 11.7 million—according to the Chicago-based Market Research Corporation of America.
For those who dislike eating breakfast, however, there is some good news. Several studies in the last few years have shown that, for grown-ups especially, there may be nothing wrong with omitting(省略) breakfast. “Going without breakfast does not affect work,” said Arnold E. Bender, former professor of nutrition at Queen Elizabeth College in London, “nor does giving people breakfast improve work.”
Scientific evidence linking breakfast to better health or better work is surprisingly inadequate(不适当), and most of the recent work involves(涉及) children, not grown-ups. “The literature,” says one researcher, Dr Earnest Polite at the University of Texas, “is poor.”
The main idea of the passage is _______.
A. breakfast has nothing to do with people’s health
B. a good breakfast used to be important to us
C. breakfast is not as important to us as gasoline to a car
D. breakfast is not as important as we thought before
For those who do not take breakfast, the good news is that _______.
A. several studies have been done in the past few years
B. the omission of breakfast does no harm to one’s health
C. grown-ups have especially made studies in this field
D. eating little in the morning is good for health
The underlined part “nor does giving people breakfast improve work” means _______.
A. people without breakfast can improve their work
B. not giving people breakfast improves work
C. having breakfast does not improve work, either
D. people having breakfast do improve their work, too
The word "literature" in the last sentence refers to _______.
A. stories, poems, play, etc
B. written works on a particular subject
C. any printed material
D. the modern literature of America
What is implied but not stated by the author is that _______.
A. breakfast does not affect work
B. Dr Polite works at an institution of higher learning
C. not eating breakfast might affect the health of children
D. Professor Bender once taught college courses in nutrition in London
【小题1】D
【小题2】B
【小题3】C
【小题4】B
【小题5】C
解析:
文章主要告诉我们关于早餐问题的最新研究成果
【小题1】D。主旨大意题。文章先讲传统观念, 强调早餐的重要;再讲最新研究成果, 表明不吃早餐也不会影响工作和健康, 通过对比阐明最新研究成果,故答案选D。
【小题2】B。事实细节题。从…for grown-ups especially, there may be nothing wrong with omitting breakfast可知答案B正确。
【小题3】C。推理判断题。题目中这句话是承接前面一个否定句,nor是修饰improve, 由此可知这句话的意思是吃早餐也不会提高工作效率,即答案选C。
【小题4】B。词汇猜测题。从recent work(作品)和researcher(学术研究者) 可猜出literature是著作的意思,即答案为B。
【小题5】C。推理判断题。从文章最后一段可知不吃早餐可能会影响小孩的健康,故答案选C。

There are two methods by which hydrogen (氢) can be used to power cars. The first way is to use hydrogen to drive the engine, in much the same way as many cars use gas. The second method is to use the reaction of hydrogen with oxygen in a battery, making the car a kind of electric one.
The dream of producing hydrogen in the car while driving along by electrolyzing(电解)water is a long way off, so we are still at the period of batteries and filling the tank with hydrogen gas. This is the difficulty for potential car users and producers. There are only sixteen hydrogen filling stations in Los Angeles and none in 99% of other cities worldwide.
Indeed, some of the big name automobile producers have pulled out of the race to put the first practical hydrogen car on the streets. Ford and GM have announced that they are pulling out in America and so has Renault in France.
However, the Japanese companies are pressing on. In fact, Honda introduced its first hydrogen fuel cell car in 1999. They are now producing second generation hydrogen car known as the FCX Clarity. Guess where they are available for sale? In only one city because of its filling stations.
Honda thinks that they could go into full-scale production of the FCX Clarity by 2020 if the world is prepared for them by then.
Then there are hydrogen-powered buses in several European cities including Amsterdam, Barcelona, Hamburg, London, Luxembourg and Madrid. Lotus, the makers of London taxis, have announced that they propose to manufacture hydrogen-powered taxis in time for the London Olympics.
So, the hydrogen vehicle is out there and the numbers will be growing fairly soon. The buses go back to their bus station, where an electrolyzing machine changes water into fuel for them to fill up on and the same will be the case for many of London’s taxis.
Unfortunately, getting fuel is not the only difficulty for the average motorist, a number of these vehicles cost about $300,000 each.
1.According to the text, hydrogen-powered buses ________.
A.can easily be filled up with gas. |
B.are likely to sell well in the future. |
C.are mainly used in the United States |
D.won’t be used in the London Olympics |
2.What does the underlined word “them” in paragraph 5 refer to?
A.Japanese companies |
B.Hydrogen buses |
C.The FCX Clarity |
D.Filling stations |
3.Where are hydrogen cars currently available for sale?
A.In Barcelona |
B.In Hamburg |
C.In London |
D.In Los Angeles |
4.We can learn from the text that ________.
A.there are sixty hydrogen filling stations all over the world |
B.hydrogen vehicles fueled by water will be very expensive |
C.Honda will mass-produce the FCX Clarity by 2012 |
D.Honda produced its first hydrogen car in 1989 |
