第二部分阅读理解(共两节,满分40分)

阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。

A

UK is becoming a popular destination for people who wish to study abroad. However, Britain is quite an

expensive place to study and live in. Tuition fees have now reached £ 9,250 a year and students also face some of the highest living costs in the world.

Fortunately, there are a number of countries where universities offer degree programs entirely in English, along with the chance to learn the local language while you live there. Here are three of the options.

Tianjin University

Moving to China is not for the faint hearted. Undergraduate degree courses at Tianjin last four years. Living costs are only around £ 400 a month and tuition fees are £ 2,300 a year. Flights will cost £ 3,600 over the four years. The total cost, at £ 28,800, is still around half that of a three-year degree in Britain. Tianjin is one of the world’s lates t cities and is only a half-hour train ride from Beijing. Three undergraduate programs are offered in English: Chemical Engineering, Environment & Energy and Pharmaceutical Science.

University of Amsterdam

The Dutch capital is not a cheap city to live in, but standard tuition fees of £ 1,800 a year make it significantly cheaper than a British degree. There are 14 bachelor’s degrees on offer that are taught in English, including Political Science, Economics & Business Economics and Actuarial Science. Nearly all Dutch people speak English, making it an easy country to get by in.

University of Milan

The University of Milan’s fees range from £ 140 to £3,650 a year. The one bachelor’s degree offered entirely in English---Political Science is a three-year course. While living costs in Milan are high, the significantly lower fees make it a cheaper option than a British university.

1. What is probably the total cost of a three-year degree in Britain?

A. £ 14,400

B. £ 27,750

C. £ 28,800

D. £ 57,600

2. Where can you major in Political Science?

A. London and Tianjin.

B. Amsterdam and London.

C. Amsterdam and Milan.

D. Tianjin and Milan.

3. What is the purpose of the text?

A. To encourage people to study abroad.

B. To introduce some affordable universities.

C. To advertise some degree programs.

D. To compare tuition fees and living costs.

【答案】1. D 2. C 3. B

On November 7, Lewis Pugh completed a one-kilometer swim in the freezing waters of King Edward Cove, off South Georgia in Antarctica. He was wearing only his swimming glasses, cap and Speedos!

Pugh is an advocate for our oceans and seas, working to protect these ecosystem with their large diversity of marine (海洋的) life. When asked why he doesn’t wear a wetsuit, Lewis says, “I ask world leaders to do e verything they can to protect our oceans. Sometimes the steps they need to take are difficult and unpopular. If I’m asking them to be courageous, I must also be. Swimming in a wetsuit would not send the right message.”

It took Pugh about 19 minutes to complete the one-kilometer swim in Antarctica where the water averaged about 1.6 degrees Celsius (摄氏度). He says that his body can only tolerate about 20 minutes in the freezing waters before it starts shutting down. As he swims, his body temperature steadily drops, which in turn causes his muscle (肌肉) control to drop, slowing him down. When he is done with his swim, his support team rushes him to a hot shower and it takes almost an hour for his body temperature to return to normal.

Doctors and Pugh caution that one must receive months of training to swim in such cold waters. Even expert swimmers who are unused to freezing water can drown within minutes because of the physical shock experienced by the body. Pugh says he trained for six months before this swim.

This is not the first time that Lewis has swum in dangerous conditions. In 2007, he swam one kilometer in the North Pole to draw attention to the melting Arctic ice due to climate change. In 2015, he swam in the Bay of Whales in Antarctica’s Ross Sea as part of his successful campaign to help set up a marine reserve there.

4. Why did Lewis Pugh swim without a wetsuit?

A. To swim faster.

B. To show his bravery.

C. To build up his body.

D. To win public attention.

5. What does the underlined word “it” in Paragraph 3 refer to?

A. His body.

B. The water.

C. His body temperature.

D. The water temperature.

6. What’s Pugh’s advice about swimming in freezing waters?

A. One must be fully prepared.

B. One should be expert at swimming.

C. One should be ready to take on challenges.

D. One must be used to long-distance swimming.

7. What may be the best title for the text?

A. Lewis Pugh: swimming for a cause

B. How to survive a swim in cold waters

C. How to prepare for extreme swimming

D. Lewis Pugh: achieving the impossible

C

Many leading AI researchers think that in a matter of decades, artificial intelligence will be able to do not merely some of our jobs, but all of our jobs, forever transforming life on Earth.

The reason why m any reject this as science fiction is that we’ve traditionally thought of intelligence as something mysterious that can only exist in biological organisms, especially humans. But such an idea is unscientific.

From my point of view as a physicist and AI researcher, intelligence is simply a certain kind of information-processing performed by elementary particles(基本粒子) moving around, and there is no law of physics that says one can’t build machines more intelligent than us in all ways. This suggests that we’ve only seen the tip of the intelligence iceberg and that there is an amazing potential to unlock the full intelligence that is potential in nature and use it to help humanity.

If we get it right, the upside is huge. Since everything we love about civilization is the product of intelligence, amplifying (扩大) our own intelligence with AI has the potential to solve tomorrow’s toughest problems. For example, why risk our loved ones dying in traffic accidents that self-driving cars could prevent or dying of cancers that AI might help us find cures for? Why not increase productivity through automation (自动化) and use AI to accelerate our research and development of affordable sustainable (可持续的) energy?

I’m optimistic that we can develop rapidly with advanced AI as lo ng as we win the race between the growing power of our technology and the knowledge with which we manage it. But this requires giving up our outdated concept of learning form mistakes. That helped us win the race with less powerful technology: We messed up with fire and then invented fire extinguishers (灭火器), and we messed up with cars and then invented seat belts. However, it’s an awful idea for more powerful technologies, such as nuclear weapons or superintelligent AI— where even a single mistake is unacceptable and we need to get things right the first time.

8. How do many people feel about leading AI researchers’ predictions?

A. Worried

B. Curious

C. Doubtful

D. Disappointed

9. What does the author think of intelligence?

A. We know little about it.

B. It belongs to human beings.

C. It is too difficult to understand.

D. We have a good command of it.

10. What does the underlined word “upside” in Paragraph 4 probably mean?

A. Cost.

B. Potential.

C. Quantity.

D. Advantage.

11. What’s importa nt for us in the race between people and technology?

A. Learning from failure.

B. Increasing our intelligence.

C. Avoiding making mistakes.

D. Making accurate predictions.

【答案】8. C 9. A 10. D 11. C

D

Air travel can be annoying. But research now suggests global warming could make it much worse. To get off the ground in really hot weather, planes may be forced to carry fewer passengers. That might mean a little more space, which would be good. However, it also would make the passengers pay more.

Average air temperatures around the world are rising because people are polluting the air with an increasing number of greenhouse gases, which, such as carbon dioxide, are a byproduct (副产品) of burning fuels. Those warmer temperatures can influence an air plane’s ability to fly because air molecules (分子) spread out more as the air warms. This produces less lift under a plane’s wings, so a plane must be lighter to take off in hot weather than on cooler days.

It can even prove too dangerous for some planes to attempt a take-off. A record of June heat wave in the American Southwest, for instance, caused flight cancellations in Phoenix, Ariz. One airline’s planes were cleared to operate only up to 47.8 degree Celsius. On June 20, Phoenix reached 48.3°C!

Radley Horton is a climate scientist at Columbia University. Two years ago, he and his graduate student Ethan David Coffel studied the impact of warming at four U.S. airports and found that warming of track could triple (使成三倍) the number of days when planes face weight restrictions. Later, they explored the impact of rising temperatures on live types of commercial planes flying out of 19 of the world’s busiest airports. In the coming decades, as many as one to three out of every 10 flights that take off during the hottest time of day could face weight. That would be equal to taking a dozen people off the plane, the researchers calculated.

12. How would global warming affect air travel according to the first paragraph?

A. It’ll add to the danger of flying.

B. It’ll increase passengers’ travel cost.

C. It’ll make flying much more comfortable.

D. It’ll encourage more people lo travel by plane.

13. What is the second paragraph actually intended to explain?

A. How global warming is happening.

B. What decides a plane’s abi lity to fly.

C. Why global warming affects flying.

D. Where greenhouse gases are created.

14. What is the last paragraph mainly about?

A. Reasons for flight cancellation.

B. The findings of a weight-related research.

C. The tendency of temperature change.

D. Effects of hot air on financial growth.

15. What should be the best title for the text?

A. Air Travel Isn’t Recommended during Hot Weather

B. Rising Temperatures May Reduce the Number of Flights

C. Weight Restrictions Are More Common in More Airports

D. Hotter Air May Lead to Planes Carrying Fewer Passengers

【答案】12. B 13. C 14. B 15. D

第二节(共5小题;每小题2分,满分10分)

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month.___16___

One idea is that sleep helps us strengthen new memories. ____17____ We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.

Support is growing for a theory that sleep evolved so that connections between neurons (神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day.___18___

Now we have the most direct evidence yet that he is right.____19____ The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.

If Tononi’s theory is right, it would explain why, when we miss a night’s, we find it harder the next day to concentrate and learn new information — our brains may have smaller room for new experiences.

Their research also suggests how we may build lasting memories over time even though the synapses become

thinner. The team discovered that some synapses seem to be protected and stayed the same size. ____20____ “You keep what matters,” Tononi says.

A. We should also try to sleep well the night before.

B. It’s as if the brain is pres erving its most important memories.

C. That’s why students do better in tests if they get a chance to sleep after learning.

D. Similarly, when people go for a few days without sleeping, they get sick.

E. The processes take place to stop our brains becoming loaded with memories.

F. Tononi’s team measured the size of these connections, or synapses, in the brains of 12 mice.

G. “Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea.

考试六大应试技巧 一、自我暗示、消除焦虑 ①自我暗示法。用平时自己考试中曾有优异成绩来不断暗示自己:我是考生中的佼佼者;我一 定能考得理想的成绩;我虽然有困难的题目,但别人不会做的题目也很多。 ②决战决胜法。视考场为考试的大敌,用过去因怯场而失败的教训鞭策自己决战决胜。 二、整体浏览,了解卷情 拿到试卷后,在规定的地方写好姓名和准考证号后,先对试卷进行整体感知,看看这份试卷共 多少页、总题量是多少、分哪几大部分、有哪几种题型。这样不仅可以要防止试卷错误,尽早调换, 避免不必要的损失;而且通过对全卷作的整体把握,能尽早定下作战方案。重要的是初步了解下试 卷的难易度,以便自己合理安排答题时间,避免会做的没有做,不会做的却浪费了时间的情况出现。 三、“两先两后”,合理安排 ①先易后难 ②先熟后生 四、“一慢一快”,慢中求快 一、书写速度应快,不慢慢吞吞。二、书写的内容要简明扼要,不拖泥带水,噜嗦重复,尽量 写出得分点就行了。 五、分段得分,每分必争 对于会做的题目。对会做的题目要解决对而不全的老大难问题,如果出现跳步往往就会造成丢 分的情况,因此,答题过程一定规范,重要步骤不可遗漏,这就是分段得分。 对于不会做的题目,这里又分两种情况,一种是一大题分几小题的,一种是一大题只有一问的。 对于前者,我们的策略是“跳步解答”,第一小题答不出来,就把第一小题作为已知条件,用来解答 第二小题,只要答得对,第二小题照样得分。对于后者,我们的策略是“缺步解题”,能演算到什么程度就什么程度,不强求结论。这样可以最大程度地得到分数。 六、重视检查环节 如果自己的考试时间还有些充裕,那么根不可匆忙交卷,而应作耐心的复查。将模棱两可的及 未做的题目最后要进行检查、作答,特别是填空题、选择题不要留空白。
