【題目】Taxi-sharing could have a good effect on car numbers.

Taxi-sharing services could reduce the number of cars on the road by 75%,a study has suggested.The Massachusetts Institute of Technology (MIT) study found that a number of 3,000 four-passenger taxis could take the place of the present number of 13,000 yellow taxis in New York City.But it would mean that people would have to travel with strangers.The study was based on data from 3 million taxi rides.

Most experts who are looking at our city future agree that there is a real need to do something about the heavy traffic.Studies suggest that around the world people waste 7 billion hours each year sitting in traffic.And the effects on the environment are also severe-with cars in traffic burning 3 billion more gallons of gas.

Prof Daniela Rus from MIT's Computer Science and Artificial Intelligence Lab writes,"Instead of taking one person at a time,drivers could transport two to four people at once,leading to fewer trips in less time to make the same amount of money."The team developed a math method that could arrange cars based on real-time requests."A system like this could allow drivers to work shorter time,while also creating less traffic,cleaner air and less stressful rush hour,"said Prof Rus.Such a system would be particularly suitable for smart cars controlled by computer systems, she added.

【1】What's the shortcoming of sharing a taxi?

A. Passengers have to wait longer.

B. Passengers have to face strangers.

C. Passengers have to talk more.

D. Passengers have to pay more.

【2】What is the main cause that leads to taxi-sharing?

A. The busy people. B. The serious pollution.

C. The heavy traffic. D. The gas shortage.

【3】According to Prof Daniela Rus,who can also benefit from taxi-sharing?

A. The gas companies. B. The math experts.

C. The car producers. D. The taxi drivers.

【4】The taxi-sharing trips had better to be carried out by .

A. cars controlled by computer systems

B. cars driven by the latest robots

C. the Science and Artificial Intelligence Lab

D. the Massachusetts Institute of Technology

【答案】

【1】B

【2】C

【3】D

【4】A

【解析】本文講述了專家針對交通擁擠的情況采取的措施-共享出租的實(shí)行，雖然選擇出租車共享服務(wù)就意味著人們不得不和陌生人一起旅行，但是共享出租不僅可以緩解現(xiàn)在的交通壓力，出租車司機(jī)也能從中獲益。

【1】細(xì)節(jié)理解題。根據(jù)文章第一段“But it would mean that people would have to travel with strangers”可知，選擇出租車共享服務(wù)就意味著人們不得不和陌生人一起旅行。故選B。

【2】細(xì)節(jié)理解題。根據(jù)文章第二段“Most experts who are looking at our city future agree that there is a real need to do something about the heavy traffic”可知，大多數(shù)關(guān)注我們城市未來的專家都認(rèn)為，確實(shí)需要對交通擁擠的情況采取措施。共享出租就是解決這一問題的措施。故選C。

【3】細(xì)節(jié)理解題。根據(jù)文章第三段“Instead of taking one person at a time, drivers could transport two to four people at once, leading to fewer trips in less time to make the same amount of money.”可知，實(shí)行出租共享后，司機(jī)可以一次運(yùn)送兩到四個人，而不是在同一時間運(yùn)送兩個人到同一個人，這樣一來，在更短的時間內(nèi)就可以掙到同樣數(shù)量的錢�？梢姽蚕沓鲎庖矠槌鲎廛囁緳C(jī)帶來利益。故選D。

【4】細(xì)節(jié)理解題。根據(jù)文章第三段“Such a system would be particularly suitable for smart cars controlled by computer systems”可知，這樣一個共享出租智能系統(tǒng)將特別適合由計(jì)算機(jī)系統(tǒng)控制的智能車。故選A。

【題目】Over millions of years, penguins（企鵝）have developed a keen sense of where to find food. Once they’re old enough, they set off from the shores on which they were hatched for the first time and swim long distances in search of tasty fish like anchovies and sardines. But they don’t search directly for the fish themselves.

For example, when young African penguins head out to sea, they look for areas with low surface temperatures and high chlorophyll(葉綠素) because those conditions signal the presence of phytoplankton（浮游植物）. And lots of phytoplankton means lots of plankton（浮游動物）, which in turn means lots of their favorite fish. Well, that’s what it used to mean.

Climate change plus overfishing have made the penguin feeding grounds a mirage(海市蜃樓). The habitat is indeed plankton-rich—but now it’s fish-poor. Researchers call this an “ecological trap.”

“It’s a situation where you have a signal that previously pointed an animal towards good quality habitat. That habitat’s been changed, usually by human pressures. The signal stays, but the quality in the environment deteriorates.”

Richard Sherley, a zoologist at the University of Exeter and his team used satellite imaging to track the African penguins from eight sites along southern Africa. Historically, the birds benefited from tons of fish off the coasts of Angola, Namibia and western South Africa, but now they’re going hungry.

“I was really hoping we’d see them going east, and finding areas where the fish had moved to but it ends up being quite a sad story for the penguins.” said Richard.

The researchers calculate that by falling into this ecological trap, African penguin populations on South Africa's Western Cape have declined by around 80 percent.

Some research groups are exploring the idea of moving chicks to a place where they can’t get trapped, like the Eastern Cape. But Sherley thinks that a longer-term solution means making and carrying out rules to create more sustainable(可持續(xù)的) fishing industry, something that he says needs public support.

【1】How do penguins find their food?

A. They discover fish with their keen sense.

B. They swim long distances directly for fish.

C. They make signals to each other when finding fish.

D. They look for warmer and greener areas.

【2】What is an ecological trap for the African penguins?

A. A trap set to catch penguins.

B. A good fish habitat with few fish.

C. A habitat unsuitable for fish.

D. A mirage on the sea.

【3】What does the underlined word “deteriorates” in the fourth paragraph mean?

A. Get worse. B. Get better.

C. Stay the same. D. Become suitable.

【4】What can be done to help the penguins in the long run?

A. Move the penguins to other places.

B. Create nature reserves for penguins.

C. Keep a balanced fishing industry.

D. Increase the population of penguins.

Today I’d like to tell you anything about riding a bike in London. If you visit London, you’ll see many buses, cars or bikes. It’s very cheap and quick to use bike. If you take a bus, I often have to wait for an hour or so. Besides, the buses move very slowly. The underground is quickly but expensive and often crowded. I used to travel to work by bus. I was often late, and tiring. Then a friend suggested we went to work by bike. I followed him. Although we went slowly, but we always arrived on time. Taking a bus takes 50 minutes, while ride a bike only half an hour. Now I love riding to work and I feel more better.
