OneRoomAirconditioner—$50Date:-优题课

It is known to us that puter users are being warned by industry experts to pay attention to secret codes which could be used to record their conversation.
E-mails, screen savers, and electronic greeting cards can carry a secret code which is able to turn on the puter’s microphone, make a recording, and forward it to someone else without the user’s knowledge.
In fact any attachments (附件) sent to a puter, whether it is a game of Space Invaders, or a moving picture, can possibly be used to spy (窥探).
Experts say people should always think twice about opening attachments because --- although not mon --- bugging (窃听) by puter can and has been done.
Bill Lyons, head of the Internet Security pany Finjan, said, “People in the army have tested this and you can be sure, if people in general are aware of it, then puter hackers (黑客) are aware of it. The frightening thing is that there are tools on the Internet which people, using a simple search method, can find, and which will enable them to attach this dangerous code to simple attachments.”

D．Never use secret codes.

What worries the experts is that ___ .

A．nobody seems to believe such things

B．nobody knows the danger of the code

C．tools can easily be used to tie dangerous codes to e-mails

D．Any attachments sent to a puter may carry a secret code.

Yasuda is 95 years old. Looking for easier ways to search the Web and send email, he bought Apple’s iPad. The pany has sold 3.27 million iPads since they entered the market in April. Although it’s impossible to know with certainty how many seniors (老年人) are buying them, evidence suggests that it’s a hit with seniors.
The iPad’s intuitive interface (直观界面) makes it attractive to seniors around the world, says Takahiro Miura, a researcher at the University of Tokyou. “The iPad is a good tool for seniors because it’s very easy to use,” he says. “Unlike the PC, it doesn’t require former knowledge.”
James Cordwell, a researcher in London, says the iPad’s popularity with seniors is helping Apple reach beyond its traditional base of young customers. “The world’s population, especially in developed markets, is getting older. It’s probably a market where Apple has least entered, ” Cordwell says. Senior users are “a key source of growth for them in the future.”
Seniors make up about 22 percent of the population in Japan. They may prove that seniors are willing to accept the iPad. Besides the customer group under 30, they spend more than any other group in the country, according to a report. Motoo Kitamura, 78, a former gas salesman, bought an iPad to help him municate with his 2-year-old grandson and prevent him from experiencing some of the mental problems that sometimes e with getting older. “Trying new things like that is good mental exercise,” he says.

A．a sudden attack

B．a heavy burden

C．quite popular

D．very familiar

A．It has intuitive interface.

It was the end of the school term and my son Tom had less than three months left before he would finish his six years at high school. During this time he had developed a love for basketball. Sadly, because of my work over the last twelve months, I had only been able to attend a few of his games; however, I was determined to get to his last game for the school term.
Tom’s team came out in the first 10 minutes with a burst of goals that saw them leading by just over 20 points at the end of the first half. The second half changed as the other team quickly played themselves back into the game. Tom’s team started to miss an increasing number of shots. It was at that point that the coach called his first time out.
The noise of the spectators (观众) became quiet as the coach spoke to them. He had the team standing in a half circle, but he squatted (蹲) down, looking up at them and fiving some very calm and clear instructions on what they needed to do in the last couple of minutes. As he stood up to allow the team to return to the court, I saw him give some further words of encouragement to all of them.
You could see that he knew that the team was fighting to save the game and that he needed to lift them up. By squatting down he placed himself in a position where he was talking up to them, rather than down or at them, and as the players went back onto the court his words of encouragement served to lift their energy and spirits.
Well, Tom’s team went on to win the final by 5 points. As I drove away I thought about what can happen to us all in our everyday life. One of my favourite quotes is about the half filled glass of water --- “Is it half full or is it half empty?” Like the coach, the answer to this quote all depends on how you look at things.

A．Because his son would graduate from high school.

B．Because he felt sorry for never watching his son play.

C．Because it was a final his son played a key role in.

D．Because he had a strong interest in basketball himself.

By squatting down, the coach wanted to _____ .

A．talk about what the players were doing wrong

B．make the players feel better

C．prevent spectators from hearing what he said

D．show his anger at the bad performance of the players

What is the writer’s attitude towards the coach?

A．Negative.

B．Supportive.

C．Interested.

D．Unconcerned.

What can we infer from the passage?

A．A father should care about his son at school.

B．Playing hard is rewarded with a close match.

C．What a coach says has the most influence on players.

D．Looking at things positively is important in hard times.

Losing weight comes with a lot of health benefits—including making your brain sharper.
There have been few studies of overweight and cognitive functioning, (认知功能) possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Yet, it turns out that overweight may damage cognitive functions such as memory and attention. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University.
Growing evidence suggests that being fat is linked to cognitive deficits (缺陷). So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn’t lose weight dropped even further.
The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he’s seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way—eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. “If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well,” he says.
There is less research on overweight and cognitive functions because researchers _____.

A. believe overweight only affects our body

B. have focused on ways to sharpen people’s mind

C. do not consider overweight a main cause for low cognitive ability

D. are clear about the relation between weight and mental functions

A. losing weight has little effect on people’s memory

B. losing weight can improve people’s mental functions

C. overweight people are likely to have psychology problems

D. overweight people’s abilities of concentration differ greatly

What is Gunstad planning to prove next in his research?

A. Slim people are smarter than overweight people.

B. Healthy diet is better than exercise in losing weight.

C. Traditional ways of losing weight are better than operation.

D. Overweight people will get smarter by taking more exercise.
