科目:高中英語 來源:2011年吉林省高考復習質量監測英語卷 題型:閱讀理解

It seems that every week someone becomes “the first” or “the youngest” or even “the first married couple” to do something that doesn’t seem to be very useful to the rest of us.
Why do they do it? Don’t they have better things to do with their time and money? And why should I be interested anyway? Human beings have already climbed the highest mountains, sailed across the oceans and flown around the world. Many of these things were done a long, long time ago. There just isn’t anything left to explore nowadays. I suppose there’s still a lot of the universe left, and the bottom of the ocean is still a bit of a mystery, but you need a lot of technology to explore areas like that. So, those people who feel the need for adventure can only do things that have been done before.
In May of this year a British man became the first person to walk alone from Canada to the North Pole. Personally, if I wanted to visit the Arctic, I’d rather go as a tourist on a cruise ship, with a helicopter trip to the North Pole included in the price. But OK, this man decided that he wanted to walk. The problem was that he went in the spring when the ice begins to melt and break up. So he got stuck on a longely piece of ice and a plane had to be sent in to rescue him.
These sorts of rescues are making many Australians angry with these record breakers. People trying to break sailing or rowing records get into trouble in the seas. So the Australian navy has to send ships to save them and this costs the government millions of dollars. I suppose we can’t just leave them to drown but we should give the bill to the people who are rescued.
【小題1】According to the author, the so-called record breakers          .

A.do not benefit other people at all
B.inspire people to continue exploring
C.are boring and should be stopped
D.are usually not wealthy enough
【小題2】We can infer from the second paragraph that          .
A.there are no high mountains for people to climb
B.nothing is left for people to explore in the universe
C.it’s beyond ordinary people to explore the unknown
D.human beings could fly around the world long ago
【小題3】Many Australians are angry because the record breakers        .
A.often get into trouble
B.never use a cruise ship or a helicopter
C.never pay their own costs
D.satisfy their needs at the cost of others’ interest
【小題4】What is the writer’s attitude towards the record breakers?
A.Positive.B.Negative.
C.Uninterested.D.Neutral(中立的).

B
Honesty may well be the policy, but it often deserts us when no one is watching, psychologists report today. Experiments with an honesty box to collect payments for hot drinks show that people are better at paying up when under the gaze(注視) of a pair of eyes. The surprise was that the eyes were not real, but photographed.
Researchers at Newcastle University set up the experiment in secret. They attached a poster to a cupboard of mugs above an-honesty box alongside a kettle, with tea, coffee and milk. Over 10 weeks, they alternated each week between images of eyes and pictures of flowers.
Dr. Bateson, a behavioral biologist and leader of the study, said that even though the eyes were not real they still seemed to make people behave more honestly. They effect may arise from behavioral characteristics that developed as early humans formed social groups that increased their chances of survival. Individuals had to co-operate for the good of the group, rather than act selfishly.
"If nobody is watching us it is in our interests to behave selfishly. But when we think we're being watched we should behave better, so people see us as co-operative and behave the same way towards us, "Dr. Bateson said.
"We thought we'd get a slight effect with eyes, but it was quite striking how much difference they made. Even at a subconscious(潛意識的) level, it seems people respond to eyes, and that might be because eyes send a strong biological signal we have evolved(進化) to respond to."
The finding, which researchers believe sheds light on our evolutionary past, could be turned to practical use. The psychologists say images of eyes could promote ticket sales on public transport and improve monitor systems to prevent antisocial behavior.
45. This passage is mainly about _______________.
A. the policy of honesty            B. an honesty box to collect money
C. evolution on honesty              D. an experiment on honesty
46. The reason for doing the experiment secretly is that the researchers _____________.
A. wanted to get a comparatively more exact result
B. had known they wanted to do something illegally
C. meant to get the co-operation of their colleagues
D. intended to sell the hot drinks at a higher price
47. People behave honestly under watchful gaze of eyes because _____________.
A. they want to leave a good impression   B. they fear to be laughed at by others
C. they've got the nature through evolution D. they take the photo for a real pair of eyes
48. Images of a pair of eyes can be applied to all except _____.
A. tickets sales on public transport        B. cold drink sales in public places
C. places with “No spitting!” signs         D. Christmas decorations in one’s home
