Vitamin E supplements(补充品)，which millions take in the hope of longer, healthier lives, may do more harm than good, researchers reported on Wednesday.?

In fact, people taking high doses(剂量)of vitamin E may in some cases be more likely to die earlier, although the reasons are not clear, said Dr. Edgar Miller of Johns Hopkins University in Baltimore, who led the study.“I think people take vitamin E because they think it is going to make you live longer, but this(study)doesn’t support that.”Miller told reporters.?

Miller and colleagues re?analyzed 19 studies of vitamin E and health between 1993 and 2004. The tests involved more than 136,000 mostly elderly patients in North America, Europe and China. People who took 200 international units of vitamin E a day or more died at a higher rate during the study, which lasted three years, than people who did not take supplements, they told a meeting of the American Heart Association.“It’s about a 5 percent increased risk at 45 years in the tests combined together，”Miller said.“That doesn’t sound like a lot but if you apply it to 25 percent of the (U.S.)adult population taking vitamin E, that is significant.”?

Miller, whose findings are also being published online by the Annals of Internal Medicine, said two?thirds of people who take vitamin E supplements take 400 IU or more.“We don’t think that people need to take vitamin E supplements, which they can get enough from the diet,”he said. Nuts, oils, whole grains and green leafy vegetables are all rich in vitamin E.?

Just put your special clothes on in the morning and you could jump 3 meters into the air and even carry more than 60 kilograms without getting tired. The walk to school would be very , very easy. Such supercharged clothing is one of the products that could be created using “wearable robotics” technology.

Designed to improve a person’s senses and skills, the device could be as simple as a hearing aid. Or it could be a full-body suit that senses what you’re going to do, then helps you do it better.

“A superman suit would be the final result in wearable robotics,” said Francois Pin, head of robotics and energy systems at the Oak Ridge National Laboratory（橡树林国家实验室）, US. While these suits are at least ten years away, in some areas the technology is already in use.

Researchers are developing artificial arms and legs that allow old, disabled or injured people to move freely. Thus US Army is interested in using wearable robot legs to help soldiers run faster, carry more equipment and be stronger in battle. Jobs that involve lifting heavy loads or saving lives from the rubble of an earthquake could also become much easier.

A robot is a device that responds to a command. You’re probably with simple robots, such as toy cars or airplanes that respond to buttons you push on a remote control.

Wearable robotics goes further. Instead of just receiving information through a wire or remote control, the robotic device can send information back to its controller.

Suppose you wore a sleeve that has sensors where your joints are. Every time you move your arm, the sleeve senses your movements and sends the information to a robot, which then moves its arm just as you did. When the robot hits or touches something, it sends a signal back to the sleeve and you sense the action.

In this way, scientists are working to wrap the robot around the person. Their goal is to make the sleeve, shoe or suit help you do what you want to do.

Which of the following can replace the underlined word “supercharged” in Paragraph one?

A．expensive B．overcharged

C．advanced D．full of electricity

Products resulting from this wearable robotics technology do not include ________.

A．remote controls B．hearing aids

C．wearable robot legs D．superman suits

From the passage, we can infer that_______________.

A．it will be ten years before robotic devices are in use

B．the wearable robotics technology has been employed in some areas

C．the robots in the robotic devices will do whatever you want to do

D．people must become lazier and less healthier in the future

My newly-rented small apartment was far away from the centre of London and it was becoming essential for me to find a job, so finally I spent a whole morning getting to town and putting my name down to be considered by London Transport for a job on the underground. They were looking for guards, not drivers. This suited me. I couldn’t drive a car but thought that I could probably guard a train, and perhaps continue to write my poems between stations. The writers Keats and Chekhov had been doctors. T.S. Eliot had worked in a bank and Wallace Stevens for an insurance company. I’d be a subway guard. I could see myself being cheerful, useful, a good man in a crisis. Obviously I’d be overqualified but I was willing to forget about that in return for a steady income and travel privileges — those being particularly welcome to someone living a long way from the city centre.

The next day I sat down, with almost a hundred other candidates, for the intelligence test. I must have done all right because after about half an hour’s wait I was sent into another room for a psychological test. This time there were only about fifty candidates. The interviewer sat at a desk. Candidates were signaled forward to occupy the seat opposite him when the previous occupant had been dismissed, after a greater or shorter time. Obviously the long interviews were the more successful ones. Some of the interviews were as short as five minutes. Mine was the only one that lasted a minute and a half.

I can remember the questions now: “Why did you leave your last job?” “Why did you leave your job before that?” “And the one before that?” I can’t recall my answers, except that they were short at first and grew progressively shorter. His closing statement, I thought, revealed (揭示) a lack of sensitivity which helped to explain why as a psychologist, he had risen no higher than the underground railway. “You’ve failed the psychological test and we are unable to offer you a position.”

Failing to get that job was my low point. Or so I thought, believing that the work was easy. Actually, such jobs — being a postman is another one I still desire — demand exactly the sort of elementary yet responsible awareness that the habitual dreamer is least qualified to give. But I was still far short of full self-understanding. I was also short of cash.

The writer applied for the job chiefly because _________.

A．he wanted to work in the centre of London

B．he could no longer afford to live without one

C．he was not interested in any other available job

D．he had received some suitable training

The writer thought he was overqualified for the job because _________.

A．he often traveled underground B．he had written many poems

C．he could deal with difficult situations D．he had worked in a company

The length of his interview meant that _________.

A．he was not going to be offered the job

B．he had not done well in the intelligence test

C．he did not like the interviewer at all

D．he had little work experience to talk about

What does the writer realize now that he did not realize then?

A．How unpleasant ordinary jobs can be. B．How difficult it is to be a poet.

C．How unsuitable he was for the job. D．How badly he did in the interview.

What’s the writer’s opinion of the psychologist?

A. He was very aggressive. B. He was unhappy with his job.

C. He was quite inefficient. D. He was rather unsympathetic.

Are you ready to do your bit to stop global warming? On Saturday, March 29, you will have a chance-to tell Toronto and the entire world that you are devoted to doing your part.

You can do it by turning off your lights during Earth Hour, from 8 p.m. to 9 p.m. Started last year by the World Wildlife Fund in Sydney, Australia, Earth Hour this year is going international, with 17 cities signed up so far, including Toronto.

The challenge for us Torontonians will be to show we are as devoted to fighting global warming as Sydneysiders were last year. Of course, one hour of darkness isn't going to stop global warming. But the thinking behind Earth Hour is that it gets people personally involved(加入). Besides giving people a chance to show their concerns over climate change, the goal is to get them to start changing their wasteful habits. Did you know, for example, that your electronic devices(设备) that you think you've turned off are still drawing power if you leave them plugged in?

If you want to make a difference, sign up today and promise to turn off your lights when Earth Hour arrives on March 29. Persuade others to do their part. Start to think about changes that can be made in your home and your workplace that will cut down on waste and greenhouse gas.

What can be the best title for the passage?

A. A Chance to Help Save the Earth B. A Chance to Help Prevent Pollution

C. An Hour to Fight Against Bad Habits D. An Hour to Keep Climate Unchanged
