There was once a captain who loved money so much that he cheated his sailors at the end of every voyage and took their wages.
On the last day of one voyage, the ship was in a small port. It was winter time, and the sea was very cold, so the captain said to his sailors, "If one of you stays in the water during the whole night, I will give him my ship. But if he comes out before the sun appears, I shall get his wages."
The sailors had heard about the captain's cheating, so they didn't trust him. But then one of them, who thought that he was cleverer than the captain, said that he would do it. He got into the water, and, though it was very cold, he stayed in it. When it was nearly morning, some fishermen lit a fire on the shore about half a mile away.
"You are cheating," the captain said to the sailor. "The fire's warming you."
"But it's half a mile away!" said the sailor.
"A fire's fire," answered the captain. "I have won."
The sailor came out of the water, and said, "Perhaps you think that you are clever because you have won my wages, but you can't cook a chicken."
"I can," answered the captain.
"If you cook this chicken," said the sailor, "I shall work for you without wages for seven years, but if you can't, you will give me your ship."
The captain agreed, took the chicken and said, "Where's the fire?"
"There it is," answered the sailor. "On the shore."
"But it's half a mile away," said the captain angrily.
"A fire's fire,' you said," answered the sailor. "If it is enough to warm me in the water, it is enough to cook your chicken."
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.
At end of the 16th century, about five to seven million people spoke English. Nearly all of (they) lived in England. They were native speakers. Later in the next century, people from England made (voyage) to conquer other parts of the world and English began to be spoken worldwide. Today, the number of people (learn) English in China is increasing (rapid). Besides, people from many other countries also speak English their foreign language.
The English language has been changing quite a lot over the last four centuries. Old English sounded more or less like German for it (base) on German, but gradually between AD 800 and 1150, English became less like German those who ruled England spoke first Danish and later French.
Two people had great effects on the English changes. One was Shakespeare, who (rich) the English vocabulary, making English with more words; the other was Noah Webster, who wrote a dictionary gave American English its own identity.
