【正文】 re concerned about the effects their actions have on others.（1）What may make others feel that。 Why might guilt lead to trustworthy behavior? The researchers found people who were guiltprone also reported feeling an obligation to act in ethical (合乎道德的) and responsible ways while interacting (互動) with their partners in the game. People who are guiltprone tend to avoid engaging in behavior that might harm or disappoint others. If they do something bad, guilt encourages them to try to make things right again. Throughout our daily lives, we have known plenty of people and will know more. But how can we tell if someone is trustworthy? In a paper published recently in the Journal of Personality and Social Psychology, researcher gave us the answer.8．閱讀短文，從每題所給的A、B、C和D四個選項中，選出最佳選項。故選A。通讀全文可知，為了減少鹿所造成的交通事故，科學家引進了美洲師動物，有效的重新引入了了大型的食肉動物讓事故減少了許多。故選C。但這將是一個艱難的銷售：媒體將報道美洲獅的襲擊，但從統(tǒng)計上防止死亡并不能成為新聞。根據(jù)最后一段中的Indeed, the statistics show that cougars would prevent five times as many human deaths from deerrelated accidents as they would cause by attacks. But it39。故選A。每年將減少5人死亡，680人受傷。 （2）考查細節(jié)理解。由此可推斷出carnivore指的是“食肉動物”。ve been driven out.”她認為這將有助于將美洲獅等食肉動物重新引入它們被驅(qū)逐出的歷史區(qū)域會有所幫助。 That39。 （1）考查詞義猜測。Deer Cause Huge Life LossesD.Puma: a Tough SellB.Because the benefits are not as eyecatching as its risks.D.Because the risks outweigh the benefits.B.To reduce people39。To maintain biodiversity and ecological balance.C.A grasseating animal.（2）Why do people want to bring back mountain lions? A.A dangerous animal.C.ll be a tough sell: the press will cover cougar attacks, but a statistically prevented death does not make the news. Nevertheless, If people in the west can put up with having mountain lions around, I would hope that New Yorkers would be up for the challenge as well.（1）What is closest in meaning to the underlined word carnivore in Paragraph 3? A.s possible to just pletely clear it with statistics… What I hope is that knowing that there actually can be some measurable benefits might make people a little more supportive and maybe balance that fear a little bit. says Laura. Our fear of large predators is so natural and intense that I don39。 Still, some folks might be understandably nervous about this kind of plan. After all, reintroducing predators doesn39。ve been driven out. That39。re far more likely to be killed or injured by a deer skipping across the road. 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科技類閱讀，要求考生在捕捉細節(jié)信息的基礎(chǔ)上，進一步根據(jù)上下文的邏輯關(guān)系，進行分析，推理，概括和歸納，從而選出正確答案?？v觀全文可知,文章主要講Rod Rainey用古老的方法代替?zhèn)鹘y(tǒng)的輪機進行潮汐發(fā)電,打破River Severn不適宜潮汐發(fā)電的舊思想。故選B。 （3）考查細節(jié)理解。根據(jù)第二段中的Engineers and governments have been toying with the idea since at least 1925.和最后一段中的Environmentalists also worry that any plant would change the tides, making life harder for wildlife.可知,工程師對潮汐電站的想法漫不經(jīng)心,環(huán)境主義者擔心它會給海洋生物帶來危險,所以最初人們對潮汐發(fā)電站都是不支持的。故選A。根據(jù)第一段中的Its tidal range, the difference in depth between high and low tides, of around 15 metres is among the largest in the world.它的潮汐差,即最低和最高潮汐的深度差,是大約15米,位居世界首位。而名叫Rod Rainey的工程師最近想到了解決問題的辦法,雖然用的是過去的科技,但在輪上做了很大改進,這樣在保證海洋生物和環(huán)境安全的同時也可大量發(fā)電。s the best tittle for the text? invented turbines.39。Its power plant makes life harder for wildlife.（2）What was people39。It has the largest tidal range in the world.C.s wheels. Thirty metres high and sixty wide, they would be made from ordinary steel. Two hundred and fifty of them, along with the supporting structures, would be floated into place and secured to the seabed, creating a line 15km long. Together, they could supply power at an avenge ate of 4GW. That is about as much as two biggish nuclear power stations would manage. Substituting one of the wheels with a set of locks would provide a shipping channel about twice the width of Panama Canal, permitting upstream ports such as Avonmouth and Cardiff to continue operating.（1）What is special about the mouth of the River Seven? A. An engineer called Rod Rainey thinks he has a way around both problems. He plans to replace the conventional turbines of previous plans with a much older technology. Specifically, he plans to span (橫跨) the river mouth with a line of water wheels. This is a design that dates back to the early days of the Industrial Revolution. Examples can be found fixed to the sides of old watermills (水磨). Compared with solar and wind energy, which are booming, tidal (潮汐的) power is a loser in the clean energy petition. But if you did want to build a tidal power station, there are few better sites than the mouth of the River Severn, in Britain. Its tidal range, the difference in depth between high and low tides, of around 15 metres is among the largest in the world. 【點評】本題考點涉及細節(jié)理解，詞義猜測和主旨大意三個題型的考查，是一篇科研類閱讀，要求考生在捕捉細節(jié)信息的基礎(chǔ)上，進一步根據(jù)上下文的邏輯關(guān)系，進行分析，推理，概括和歸納，從而選出正確答案。本文主要講述了人類以及其他動物對狼的恐懼對維持健康、平衡的生態(tài)系統(tǒng)是有益的，因為食草動物不會過度繁殖，從而保護了植物的生長。故選B。根據(jù)最后一段中的“The research is one more piece of evidence for why protecting these top predators is important not just for wolves as a species, but for hundreds of species at every level of an ecosystem.”可知，這項研究再次證明了為什么保護這些食肉動物不僅對狼這個物種很重要，而且對生態(tài)系統(tǒng)的各個層面的物種都很重要。故選D。 （2）考查細節(jié)理解。根據(jù)第三段中的We were really surprised at that可知，黃石公園在意想不到的方面從重新引入狼中獲益。The introduction of wolves in Yellowstone National Park is a success.【答案】 （1）A（2）D（3）B（4）A 【解析】【分析】本文是一篇說明文，研究表明人類以及其他動物對狼的恐懼對維持健康、平衡的生態(tài)系統(tǒng)是有益的，其中黃石公園灰狼的引進就是一個典型的例子。The fear of wolves put them in danger of disappearing.C.It provides evidence that wolves are endangered animals.（4）What is the main idea of the passage?
