【題目】 Increasingly, Americans are becoming their own doctors, by going online to diagnose their symptoms, order home health tests or medical devices, or even self-treat their illnesses with drugs from Internet pharmacies （藥店）.Some avoid doctors because of the high cost of medical care, especially if they lack health insurance. Or they may stay away because they find it embarrassing to discuss their weight, smoking, alcohol consumption or couch potato habits. Patients may also fear what they might learn about their health, or they distrust physicians because of negative experiences in the past. But playing doctor can also be a deadly game.

Every day, more than six million Americas turn to the Internet for medical answers—most of them aren't nearly sceptical enough of what they find. A 2002 survey by the Pew Internet & American life Project found that 72 percent of those surveyed believe all or most of what they read on health websites. They shouldn't look up " headache," and the chances of finding reliable and complete information, free from a motivation for commercial gain, are only one in ten, reports an April 2005 Brown Medical School study. Of the 169 websites the researchers rated, only 16 are scored as "high quality.” Recent studies have found faulty facts about all sorts of other disorders, causing one research team to warn that a large amount of incomplete, inaccurate and even dangerous information exists on the Internet.

The problem is that most people don't know the safe way to surf the Web. "They use a search engine like Google, get 18 trillion choices and start clicking. But that's risky, because almost anybody can put up a site that looks authoritative (權(quán)威的)，so it's hard to know if what you’re reading is reasonable or not,” says Dr. Sarah Bass from the National Cancer Institute.

本文為議論文。越來越多的美國人成為自己的醫(yī)生，通過在線診斷他們的癥狀，但是由于互聯(lián)網(wǎng)上存在著大量不完整、不準(zhǔn)確甚至是危險的。

【1】

細(xì)節(jié)理解題。根據(jù)第一段第一句Increasingly, Americans are becoming their own doctors, by going online to diagnose their symptoms, order home health tests or medical devices, or even self-treat their illnesses with drugs from Internet pharmacies （藥店）（越來越多的美國人開始成為自己的醫(yī)生，他們上網(wǎng)診斷自己的癥狀，要求進(jìn)行家庭健康測試或使用醫(yī)療設(shè)備，甚至使用互聯(lián)網(wǎng)藥店提供的藥物進(jìn)行自我治療），可知，越來越多的美國人上網(wǎng)求醫(yī)問藥，故選B。

【2】細(xì)節(jié)理解題。第一段Patients may also fear what they might learn about their health, or they distrust physicians because of negative experiences in the past.（病人也可能擔(dān)心他們可能了解到自己的健康狀況，或者因為過去的負(fù)面經(jīng)歷而不信任醫(yī)生。）可知美國人疏遠(yuǎn)醫(yī)生是不敢面對自己的真實的健康狀況。故選C。

【3】

細(xì)節(jié)理解題。根據(jù)第二段Of the 169 websites the researchers rated, only 16 scored as “high quality”可知，169家保健網(wǎng)站，只有16家安全可靠，即占1/10。故選C。

【4】

推理判斷題。本文主要講述美國人越來越熱衷于網(wǎng)上求醫(yī)問藥，最后一段指出作者的寫作目的和主要論點(diǎn)：健康網(wǎng)站參差不齊，直接找網(wǎng)站尋求健康信息不太可靠。所以，作者認(rèn)為自己當(dāng)醫(yī)生是很危險的。故選D。

【題目】 Commuters of the future could get some relief from congested roads especially the peak-hour traffic if Uber’s plans for flying taxis work out.

The battery-powered aircraft looks like a cross between a small plane and a helicopter, with fixed wings and rotors (旋轉(zhuǎn)器). It was presented at an international technology conference in Lisbon, Portugal.

Catering for the need of shorter city travel time, the vehicle is intended to soar over traffic congestion. Uber hopes it will eventually become a form of convenient mass transport and cost commuters aboard less than using their own car, though initially it will be more expensive than that, Uber’s Chief Product Officer Jeff Holden said.

The scheme still faces plenty of challenges, including certification of the new vehicle by authorities, pilot training and constructing urban air traffic management systems that prevent collisions.

Holden declared that Uber is joining NASA’s project to expand air traffic systems, which scores of other companies already belong to.

He told The Associated Press in an interview that he has no dollar figure for the total investment. He said Uber is putting some of its own money into the project, developing software, while other investors are also involved, such as aircraft manufacturers that are developing the vehicle and real estate companies that are providing so-called “skyports” where people will catch their airborne taxi.

Uber is making a bid to reform and polish up its image which has been damaged by certain negative news. Holden said those episodes did not slow development of the flying taxi project of the great company that is in transition.

【1】What result is Uber’s flying taxis aimed to achieve?

A.Shorter city travel time.B.Smooth flow of traffic.

C.Higher economic efficiency.D.Convenience of people’s life.

【2】Which of the statement is correct according to Holden?

A.Flying taxis are more cost-effective than driving private cars.

B.Uber has to cooperate with NASA to reach it’s goal.

C.The success of this project, if possible, will polish up Uber’s image.

D.The final achievement of Uber’s goal relies not only on the company itself.

【3】What does the underlined word “episodes” in the paragraph probably mean?

A.troubleB.exchange

C.incidentD.process

【4】What is implied in the last paragraph?

A.Uber is committed to developing the flying taxi project.

B.Uber is to accomplish it’s transition period in the near future.

C.Uber’s reputation used to be ruined by rumors.

D.Uber has recovered from it’s damaged image.

【題目】 The traffic signals along Factoria Boulevard in Bellevue, Washington, generally don't flash the same length of green twice in a row, especially at rush hour. At 9:30am, the full red/yellow/green signal cycle might be 140 seconds. By 9:33am, a burst of additional traffic might push it to 145 seconds. Less traffic at 9:37am could push it down to 135. Just like the traffic itself, the timing of the signals changes.

That is by design. Bellevue, a fast-growing city just east of Seattle, uses a system that is gaining popularity around the US: intersection(十字路口) signals that can adjust in real time to traffic conditions. These lights, known as adaptive signals, have led to significant declines in both the trouble and cost of travels between work and home.

“Adaptive signals can make sure that the traffic demand that is there is being addressed, ” says Alex Stevanovic, a researcher at Florida Atlantic University.

For all of Bellevue’s success, adaptive signals are not a cure-all for jammed roadways. Kevin Balke, a research engineer at the Texas A&M University Transportation Institute, says that while smart lights can be particularly beneficial for some cities, others are so jammed that only a sharp reduction in the number of cars on the road will make a meaningful difference. “It’s not going to fix everything, but adaptive signals have some benefits for smaller cities,” he says.

In Bellevue, the switch to adaptive signals has been a lesson in the value of welcoming new approaches. In the past, there was often an automatic reaction to increased traffic: just widen the roads, says Mark Poch, the Bellevue Transportation Department’s traffic engineering manager. Now he hopes that other cities will consider making their streets run smarter instead of just making them bigger.

【1】What does the underlined word “that” in paragraph 2 refer to?

A.Increased length of green lights.B.Shortened traffic signal cycle.

C.Flexible timing of traffic signals.D.Smooth traffic flow on the road.

【2】What does Kevin Balke say about adaptive signals?

A.They work better on broad roads.

B.They should be used in other cities.

C.They have greatly reduced traffic on the road.

D.They are less helpful in cities seriously jammed.

【3】What can we learn from Bellevue’s success?

A.It is rewarding to try new things.B.The old methods still work today.

C.I pays to put theory into practice.D.The simplest way is the best way.
