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 (電池) and does not need any electricity to run it. A clockwork generator (發(fā)電機(jī)) 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.

Many companies use guards and expensive alarm systems to protect their property(財(cái)產(chǎn))。 Soon a new kind of protection will be used- robots. Engineers have been working on the first mobile robots for businesses. The robots will patrol(巡邏) factories, warehoues(倉(cāng)庫(kù))，and museums at night.
The mobile robots will move around slowly on wheels. They will be able to detect people through walls and pick up sounds, such as breaking glass. They can be fixed with lound sirens(警笛) to frighten thieves, or radios to signal police or guards.
To protect a building, a robot will have to move around without knocking into the walls. Information about the building will have to be stored in the robot’s small, built-in computer. A floor map could be programmed into the computer’s memory, for example.
A mobile robot will not be able to do everything. Unlike human guards, it will not be able to climb stairs, open doors, or move along rough ground. It won’t be able to tell the difference between friends and enemies. Because of that, people will have to be barred from the area it patrols.
One kind of mobile robot will be able to “sense” whether a chair or box has been moved and go around it. This robot will also judge size well enough so that it won’t send an alam if a cat crosses the room. And if someone tries to steal this robot, it will sound a loud, painful siren. The three-foot-tall robot will be hard to steal anyway. It will weigh about 200 pounds.
U.S companies pay almost $10 billion a year to protect their property with alarm systems and human guards. Mobile robots may be cheaper.
【小題1】Why is the new kind of robots called mobile robots?

A．Because they are able to climb stairs.B．Because they are able to send an alarm
C．Because they can open doors.D．Because they can move around slowly on wheels
【小題2】 How will a robot get directions for moving around a building?
A．From a human guard .B．From a built- in computer.
C．From another robot .D．From radio signals.
【小題3】 What does the underlined word barred mean?
A．protectedB．a(chǎn)llowed .C．markedD．prevented
【小題4】 According to the text, a mobile robot will NOT be able to ___________.
A．sense whether something has been moved.B．sense a cat crossing the room.
C．move over rough ground .D．detect people through walls.
【小題5】This text mainly describes how robots will ___________.
A．protect the museumB．set off a siren .
C．judge the size of a person.D．patrol buildings.

Why should we learn to swim?
Firstly, swimming is a good exercise for our health. Indeed doctors say it is the best exercise, because in swimming all the muscles of the body are used.

If we can swim, we have chance for saving our own lives, but if we cannot swim, we are pretty certain to be drowned. So for our own safety, we should learn to swim.

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 (大腦)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(記憶). 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 (荷爾蒙)" 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" (新陳代謝) 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.

A．It helps people rest well.B．It helps repair the body.

Happiness is important for everyone. Most people want to be happy, but few know how to find happiness. Money and success alone do not bring lasting happiness. Happiness depends on ourselves. In other words, we make our own happiness. Here are a few ways to help you be happier.
The first secret of happiness is to enjoy the simple things in life. Too often, we spend so much time thinking about the future—for example, getting into college or getting a good job-that we fail to enjoy the present. You should enjoy life’s simple pleasures, such as reading a good book, listening to your favorite music, or spending time with close friends. People who have several close friends tend(有……打算) to live happier and healthier lives.
The second secret to leading a happy life is to be active. Many people experience this, dancing or playing a sport. You can forget about your problems, and only think about the activity.
Finally, many people find happiness in helping others. According to studies, people feel good when they volunteer their time to do many meaningful things for other people. If you want to feel happier, do something nice for someone.
Title; 【小題1】

What happiness depends on?
Happiness depends on 【小題2】 ______
【小題3】_ to be happy ,
To enjoy【小題4】_____in life.
To be active.
【小題5】_.
Conclusion
Happiness is important for everyone and we make happiness by ourselves.
