【推荐2】The story of The emperor’s new clothes is one of Andersen’s best-known works. Cheaters fool the emperor into believing they have made him a fantastic suit. Courtiers (侍臣) dare not say that the emperor is naked; it takes a child to point out the obvious. How many companies have ploughed ahead with expensive projects that were favoured by the CEO, even when other managers have had doubts? The moral is that people are often too restricted by social practice to state their views.

In his new book Rebel Ideas: The Power of Diverse Thinking, Matthew Syed argues that the key to dealing with this problem is “cognitive (认知) diversity”, in other words, assembling a team of people with different perspectives and intellectual backgrounds. It is not just about selecting people for teams from both sexes and various races. Hire only Cambridge politics graduates or Stanford software engineers and they will have studied under the same professors and absorbed similar world views regardless of their gender or skin colour.

There is another element to selecting a good team: ensuring that those viewpoints are heard and respected. A study of over 300 projects by the Rotterdam School of Management found that those led by junior managers were more likely to succeed than those led by senior managers—maybe because other team members were less scared about pointing out potential dangers to someone of lower rank.

The ability to speak up within an organization, without fear of punishment, is known as “psychological safety”. Mr. Syed cites a study of teams at Google, which found that self-reported psychological safety was by far the most important factor behind successful teamwork at the technology giant.

One way to overcome shyness while brainstorming, for instance, is for everyone to write down their ideas but ensure their names are never known. That way, opinions about thoughts are less closely tied to the status of the thinker and can be tested against each other with less fear or favour.

Taping and bracing ankles

Ankle sprains(踝关节扭伤) are the most common sports-related injuries in the United States. If there was an easy way of decreasing the number and severity of these injuries, that would be great. For this very reason, the practice of taping and bracing ankles was introduced decades ago.

How, then, do taped or braced ankles decrease the incidence and severity of sprains in athletes? One explanation for how it works comes from a study which found that taped athletes had improved proprioception(本体感受), which is the body’s ability to know how fast the ankle and foot are moving and if they are starting to roll over or not. When they were compared, the athletes with taped ankles had better proprioception both before and after exercise compared with athletes using no tape. The tape’s traction(拉力)or pressure on the skin of the foot and ankle helped improve sensitivity and proprioception, resulting in fewer ankle sprains.

Another common concern often expressed by the public is that lengthened practice of taping or bracing ankles results in weak ankles that then tend to get injured more easily; this would be a strong case against taping or bracing ankles. However, a scientific study looked at the effects of consistent ankle brace use on the peroneus longus muscle. It is an important stabilizer(稳定装置)of the ankle, particularly against inversion, the most common type of ankle injury. This study showed that the peroneus longus muscle’s ability to do its job was not changed by the long-term wearing of an ankle brace.

Many studies have been completed to compare taping ankles and bracing ankles to try to determine which one is better. Most have shown that braces are slightly more effective than tape, but that both are better than no support at all. One study found that simply wearing high-top sneakers instead of low-tops prevented some ankle injuries and that high-tops plus tape had more than 50% fewer injuries than low-tops plus tape.

So whether it’s on the field or on the court, the tape or brace is an important piece of athletic equipment just like your helmet or mouth guard.

【推荐1】If two scientists at Los Alamos National Laboratory are correct, people will still be driving gasoline powered cars 50 years from now, giving out heat-trapping carbon dioxide(二氧化碳) into the atmosphere—and yet that carbon dioxide will not contribute to global warming.

In a proposal by two scientists, vehicle emissions(排放) would no longer contribute to global warming. The scientists, F. Jeffrey Martin and William L. Kubic Jr., are proposing a concept, which they have named Green Freedom, for removing carbon dioxide from the air and turning it back into gasoline.

The idea is simple. Air would be blown over a liquid solution of potassium carbonate, which would absorb the carbon dioxide. The carbon dioxide would then be put to chemical reactions that would turn it into fuel(燃料): gasoline or jet fuel.

This process could change carbon dioxide from an unwanted, climate-changing pollutant into a vast resource for renewable fuels. The cycle—equal amounts of carbon dioxide produced and removed—would mean that cars, trucks and airplanes using the synthetic(合成的) fuels would no longer be contributing to global warming.

Although they have not yet built a synthetic fuel factory, or even a small model, the scientists say it is all based on existing technology. “Everything in the concept has been built, is operating or has a close cousin that is operating.” Dr. Martin said.

The Los Alamos proposal does not go against any laws of physics, and other scientists who have independently suggested similar ideas. Dr. Martin said he and Dr. Kubic had worked out their concept in more detail than former proposals.

There is, however, a major fact that explains why no one has built a carbon-dioxide-to-gasoline factory: it requires a great deal of energy.

According to their analysis, their concept, which would cost about $5 billion to build, could produce gasoline at an operating cost of $1.40 a gallon and would turn economically practical when the price at the pump hits $4.60 a gallon.

Other scientists said the Los Alamos proposal perhaps looked promising but could not evaluate it fully because the details had not been published. “It’s definitely worth pursuing,” said Martin I. Hoffert, a professor of physics at New York University. “It’s not that new an idea. It has a couple of pieces to it that are interesting.”

1. What is the value of the scientists’ proposal?

A．It increases the productivity of a fuel factory

B．It decreases the cost of producing gasoline

C．It reduces the pollution caused by car driving

D．It promotes a new idea of environmental protection

2. The underlined part “has a close cousin that is operating” probably means the technology in the concept ________.

A．has been popular for so long

B．has been ignored by many people

C．is not appropriate for practice

D．will be put into practice in the near future

3. What is the biggest challenge in realizing the concept Green Freedom?

A．There is no theoretical basis.

B．It is not economically practical.

C．There is no solution to some technical problems.

D．Only a few scientists support the idea.

【推荐3】Terrafugia Inc. said Monday that its new flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year. The vehicle —named the Transition – has two seats, four wheels and wings that fold up so it can be driven like a car. The Transition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.

Around 100 people have already put down a $10,000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don’t   expect it to show up in too many driveways. It’s expected to cost $279,000.And it won’t   help if you’re stuck in traffic. The car needs a runway.

Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The government has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition   is now going through crash tests to make sure it meets federal safety standards.

Mann said Terrafugia was helped by the Federal Aviation Administration’s decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots would find relatively easy to meet.

1. What is the first paragraph mainly about?

A．The basic data of the Transition.

B．The advantages of flying cars.

C．The potential market for flying cars.

D．The designers of the Transition.

2. Why is the Transition unlikely to show up in too many driveways?

A．It causers traffic jams.

B．It is difficult to operate.

C．It is very expensive.

D．It burns too much fuel.

3. What is the government’s attitude to the development of the flying car?

A．Cautious	B．Favorable.
C．Ambiguous.	D．Disapproving.

4. What is the best title for the text?

A．Flying Car at Auto Show

B．The Transition’s First Flight

C．Pilots’ Dream Coming True

D．Flying Car Closer to Reality
