This could be the perfect gift for the partner, who embarrasses you on the dance floor. Smart socks, which can teach to dance, may be the answer for anyone with two left feet.
The socks have been developed as a running tool to help runners improve their skills. Thanks to the socks, users can accurately record not only how far and fast they run but also how well. It means the user maximizes their performance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibers that watch the movements of your feet. They look, feel and can be washed like normal clothes.
Sensors (传感器) record each movement and send it by an ankle transmitter (脚踝发射器) to a smart phone. Then a “virtual coach” application shows the information and can tell the user what they are doing wrong, and help to improve skill in any task with feet.
The socks should be useful to athletes and weekend joggers. “People think running is so easy and of course everybody can do it but not necessarily safely and well,” Dr. Davide Vigano said. A recent study showed that between 60 and 80 percent of runners got hurt per year. This is pretty much more than any other human activity. Researchers say the technology can also be developed to teach people how to dance, play sports such as golf, or even to help to teach women to walk better in high heels.
Mr. Vigano said, “People could all benefit from the idea. We have had interest from all sorts of sports, like skiing, football, cycling and golf. Anything where you have to use your feet can use it. It could even be put in high heels to help women walk in them safely.”
Socks are just the start, and the technology could be used in gloves, hats and boots. The socks, anklet and software package, are expected to be sold for around￡120, which will go on sale in March.

A.People who are disabled.
B.People who are interested in dancing.
C.People who are not good at dancing.
D.People who invented the socks.
2.What’s special about fibers that the socks are made of?

A.They can improve the skill of running.
B.They can help women walk better in high heels.
C.They can teach people to dance well.
D.They can be worn for days without washing.
4.According to Dr. Vigano, ________.
A.everyone can make good use of the smart socks
B.users can run as fast as they like with the socks
C.60 to 80 percent of runners would like to buy the smart socks
D.no runners will get hurt, thanks to the socks
Businesses are witnessing a difficult time, which has in turn produced influence on consumers, desire to go green. However, shoppers are still laying stress on environmental concerns.
Two thirds of customers say that environmental considerations inform their purchases to the same degree as they did a year ago, while more than a quarter say that they are now even better aware of the environmental effect on what they buy.
This may help to influence how shops store goods on their shelves. And the companies should still make efforts to become more environmentally friendly. Two out of three people think it is important to buy from environmentally responsible companies, with about one in seven saying that they had even decided to take their custom elsewhere if they felt a company’s environmental reputation was not good enough.
Harry Morrison, chief executive (主管) of the Carbon Trust, sympathizes: “I understand this situation where survival is very important now. But from environmental considerations, the clock is ticking — we don’t have much time. In addition, cutting carbon has an immediate effect as costs drop and a medium-term benefit for the brand.”
Larger companies have an extra motivation to look at reducing their carbon footprint, as new rules next year will require businesses to buy carbon allowances to make up for their emissions (排放). Those that have taken early action will have a head start. More than two thirds of consumers are not clear about which companies are environmentally responsible. This suggests that firms that are able to relay clearly their message to the public will be in a pole position to attract shoppers.
The Carbon Trust believes that it can help by informing customers about the good work companies are doing. “When companies are granted (授予) the standard, they can use a logo (标识) in all their marketing which makes it clear that they are working towards cutting emissions,” Mr. Morrison said.
1.What’s the main idea of the passage?
A.Businesses are finding ways to send their message to the shoppers.
B.Companies will soon get information about cutting carbon emissions.
C.Firms are making efforts to encourage customers to keep goods at home.
D.Firms are urged to cut carbon emissions by shoppers, environmental awareness.
2.The underlined word “inform” in Paragraph 2 probably means “ ”.
A.affect B.change
C.disturb D.reject
3.According to Harry Morrison, businesses .
A.will benefit from cutting carbon emissions
B.should buy carbon allowances for shoppers
C.are required to make up for their carbon emissions
D.have encouraged shoppers to take their custom elsewhere
4.We can learn from the passage that businesses will .
A.have a strong desire to reduce costs
B.use the same logo in their marketing
C.gain advantages by taking early action
D.attract more shoppers by storing goods
In 1977, a University of Oxford statistician named Richard Peto pointed out a simple yet puzzling biological fact: we humans should have a lot more cancer than mice, but we don’t.
Dr. Peto’s argument was simple. Every time a cell divides, there’s a small chance it will gain a mutation(突变) that speeds up its growth. Cells that accumulate (聚集) several of these mutations may become cancerous. The bigger an animal is, the more cells it has, and the longer an animal lives, the more times its cells divide. We humans undergo (经历) about 10,000 times as many cell divisions as mice—and thus should be far more likely to get cancer.
A number of scientists have assumed that large, long-lived animals must have evolved extra cancer-fighting weapons. Otherwise, these species would die out.
Dr. Joshua D. Schiffman, an oncologist (肿瘤学家）at the Huntsman Cancer Institute, reviewed zoo records on the deaths of 644 elephants and found that less than 5 percent died of cancer. By contrast, 11 percent to 25 percent of humans die of cancer.
To understand the elephants’ defenses, the scientists investigated a gene that is vital to preventing cancer called p53. The protein encoded by the gene monitors cells for damage to the DNA they contain. Dr. Schiffman and his colleagues found that elephants have evolved new copies of the p53 gene. While humans have only one pair of p53 genes, the scientists identified 20 pairs in elephants.
To see whether these extra copies of p53 made a difference in fighting cancer, they ran experiments on elephant cells. They treated elephant cells with damaging radiation, chemicals and UV light.
“In all cases, instead of trying to repair the damage, the elephant cells simply committed suicide” said Dr. Schiffman. He said he thought the way the elephant cells responded was a very effective way to block cancer.
Patricia Muller, an oncologist at the MRC Toxicology Unit at the University of Leicester, who was not involved in the studies, said the results, though convincing, didn’t firmly establish exactly how elephants use p53 to fight cancer. One possibility is that the extra copies don’t actually cause cells to commit suicide. Instead, they may act as decoys (诱饵) for enzymes (酶) that destroy p53 proteins.
Dr. Muller said it was especially important to understand precisely how elephants fight cancer before trying to copy their strategies with drugs for humans.

A.Human should be more likely to develop cancer than mice.
B.Cell division can increase the speed of growth of mutations.
C.The bigger an animal is, the smaller chance of getting cancer it has.

A.They cause the cells to repair the genes.
B.They stop cells from dividing further.
C.They act as decoys for enzymes that destroy p53 proteins.
D.They cause the cells to commit suicide.
4.Which of the following is TRUE?
A.Dr. Schiffman pointed out that we humans don’t have more cancer than mice.
B.The cancer death rate of humans is five percent higher than that of elephants.
C.The scientists found there are 20 pairs of p53 genes in elephants.
