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（精確地） record not only know far and fast they run but also how well. It means the user maximizes(最大化)their performance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibers(纖維) that watch the movements of your feet. They look, feel and can be washed like normal clothes.

Sensors record each movement and send it by an ankle transmitter (腳踝發(fā)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 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.

1.What does the underlined part “anyone with two left feet” refer to?

A. People who are disabled.

B. People who invented the socks.

C. People who are not good at dancing.

D. People who are interested in dancing.

2.What’s special about fibers that the socks are made of ?

A. They can monitor the movement of feet.

B. They feel much softer than normal clothes.

C. They are expensive to produce.

D. They act as a smart phone for users.

3.According to Dr Vigano, _____

A. 60 to 80 percent of runners would like to buy the smart socks.

B. users can run as fast as they like with the socks.

C. everyone can make good use of the smart socks.

D. no runners will get hurt, thanks to the socks.

LEEDS, England--- A Leeds University psychology professor is teaching a course to help dozens of Bristons forgive their enemies.

“The hatred we hold within us is a cancer,” Professor Ken Hart said, adding that holding in anger can lead to problems such as high blood pressure and heart disease.

More than seventy people have become members in Hart’s first 20-week workshop in London--- a course he says is the first of its kind in the world.

These are people who are sick and tired of living with a memory. They realize their bitterness is a poison they think they can pour out, but they end up drinking it themselves, said Canadian- born Hart.

The students meet in groups of eight to ten for a two-hour workshop with an adviser every fortnight.

The course, ending in July, is expected to get rid of the cancer of hate in these people. “People have lots of the attitudes towards forgiveness,” he said. “People confuse forgiveness with forgetting. Forgiveness means changing from a negative attitude to a positive one.”

Hart and his team have created instructions to provide the training needed.

“The main idea is to give you guidelines on how to look at various kinds of angers and how they affect you, and how to change your attitudes towards the person you’re angry with,” said Norman Claringbull, a senior expert on the forgiveness project. Hart said he believes forgiveness is a skill that can be taught, as these people “want to get free of the past.”

1.According to the passage if you’re angry with somebody, you should ________.

A. try your best to defeat him or her

B. break off relations with him or her

C. persuade him or her to have a talk with you

A. high blood pressure and heart disease are caused by hatred

3.If you’re a member of Hart’s workshop, you’ll _______.

A. pay a large amount of money

B. go to the course every night in twenty weeks

C. attend a gathering twice a month

D. pour out everything stored in your mind in the workshop

Tayka Hotel De Sal

Where: Tahua, Bolivia

How much: About $95 a night

Why it’s cool: You’ve stayed at hotels made of brick or wood, but salt? That’s something few can claim. Tayka Hotel de Sal is made totally of salt—including the beds (though you’ll sleep on regular mattresses (床墊) and blankets).The hotel sits on the Salar de Uyuni, a prehistoric dried-up lake that’s the world’s biggest salt flat. Builders use the salt from the 4,633-square-mile flat to make the bricks, and glue them together with a paste of wet salt that hardens when it dries. When rain starts to dissolve the hotel, the owners just mix up more salt paste to strengthen the bricks.

Green Magic Nature Resort

Where: Vythiri, India

How much: About $240 a night

Why it’s cool: Ridding a pulley(滑輪)-operated lift 86 feet to your treetop room is just the start of your adventure. As you look out of your open window—there is no glass!—you watch monkeys and birds in the rain forest canopy. Later you might test your fear of heights by crossing the handmade rope bridge to the main part of the hotel, or just sit on your bamboo bed and read. You don’t even have to come down for breakfast—the hotel will send it up on the pulley-drawn “elevator”.

Dog Bark Park Inn B&B

Where: Cottonwood, Idaho
