The Clockwork Radio
The British inventor Trevor Baylis created this really clever ′wind-up radio′ for people from Third World countries. in some parts of the Third World countries, it’s very hard for people to get or pay for enough energy. This radio uses no batteries (电池) and does not need any electricity to run it. A clockwork generator (发电机) is put inside the radio and works as the power. When it is fully wound up (上弦), the radio can work for long periods.
The clock work product is not a new invention. The Victorians had already put it in wide use. We may find them used in toys as well. Then what is new about this clockwork radio? Baylis has used this simple but effective (高效的) way of creating electricity to both help the people of the Third World and to develop a product which is selling well in Western Europe.
Even former President of South Africa, Nelson Mandella has one of these radios and personally recommends this product to others.

New York is one of the last large American cities to have some of its policemen on horseback. The New York police have 170 horses working in certain parts of the city. The horses are expensive to feed, but it is even more expensive to look after them. Because the horses must walk on the streets, they need special horseshoes. In fact , they need more than 8,000 of them each year. Every police horse in New York gets new shoes every month. Keeping these shoes in good repair is the job of six blacksmiths. There are only about thirty-five of these blacksmiths in the whole United States.
The cost of shoing a horse is between twenty dollars and thirty-five dollars, and it takes a good blacksmith two or three hours to do the job.
A blacksmith’s job is not an easy one. He must be able to shape a shoe from a piece of metal and then fit it to the horse’s foot. The blacksmith must bend over all the time when he is fitting the shoe and must hold the weight of the horse’s leg while he works. Clearly, a blacksmith must be very storng. But even more important, he must be able to deal with horses---for before the blacksmith can begin his work, he has to get the horse to lift its leg.
One of the blacksmiths in New York is James Corbin. He came to the country from Ireland in 1948. He not only makes horseshoes for the police but also works for a group of horse owners near the city. Corbin became interested in blacksmithing because his father did it, and,as the puts it, “It’s a good way to make a living.”

Most children like watching TV. It’s very interesting. By watching TV they can see and learn a lot and know many things about their country and the world. Of course ,they can also learn over the radio. But they can learn better and more easily on TV. Why? Because they can hear and watch at the same time. But they can’t see anything over the radio.

During the day, you spend a lot of time running, jumping, laughing, eating, and talking. You use up a lot of energy(能量) , and by the end of the day you’re tired. Sleep gives your body a chance to rest.
But your brain (大脑)and body are not completely at rest during sleep. While you sleep, your mind may think of the things that happened during the day. It keeps the important things in mind as memories(记忆). It also thinks about things you were worrying about, and you may wake up with answers to some of your problems.
You also grow while you sleep. The thing called "human growth hormone (荷尔蒙)" in the body helps you grow during sleep. This growth hormone also helps the body to repair itself.
Sleep helps your body to conserve energy too. You use up a lot of energy during your daily activities. But when you sleep, your body temperature falls, and your "metabolism" (新陈代谢) slows down. You are still using some energy, but much less than when you are awake and active.
Have you ever stayed up past your bedtime? Did you have difficulty getting up the next morning? Maybe you had problems seeing clearly or you cannot think clearly. That was your body’s way of saying, "I need sleep！" A lack ( 缺乏) of sleep can stop your body and mind from working correctly.
小题1:What does "human growth hormone" do while people sleep?
| A．It helps people rest well. | B．It helps repair the body. |
| C．It helps answer problems. | D．It helps slow the body down. |
| A．You use up a lot of energy. | B．You enjoy daily activities. |
| C．Your body temperature falls. | D．You don’t want to get up. |
| A．provide | B．move | C．save | D．spend |
