Last year, a special kind of glove came out. It was invented to help blind people to learn Braille, which is a special system for the blind to read by touching. Shaking motors (震动马达) are put on each finger of the glove. They can make different sounds to tell a user which letter he is touching. Recently, two British college students have invented another special glove for the blind. It can make the user feel small and quick movements. An ultrasonic sensor (超声波传感器) with a battery is put on the back of the glove. When the user wearing the glove is close to an object(物体), ultrasonic waves (超声波) from the glove are sent out (发出). As soon as they hit the object in front, the waves will return to the glove. Then the waves cause the glove to shake. And the ultrasonic sensor makes different kinds of sounds. The sounds make the user know how far he is from the object.

    In the college invention competition, the two students got first prize and won 1,540 pounds. One of the designers said, "Now the ultrasonic sensor on the glove is quite large. We're going to use the money to develop a smaller and lighter ultrasonic sensor."

    We have to be fit, no matter (不管) what age we are. It's very important for kids. That's w{#blank#}1{#/blank#} they have P.E. class.

    In Britain students have two hours of P.E. each week. P.E. includes sit-ups, press-ups (俯卧撑) and skipping rope.

    Students also p{#blank#}2{#/blank#}football, basketball and cross-country running. In summer kids run and do the high and long jumps.

    When I was at school my favourite was trampoline(蹦床). Jumping high into the air always made me excited. But you need to be c{#blank#}3{#/blank#}. Sometimes you don't land where you planned!

Some people ski(滑雪) down mountains. Others climb huge rocks. Why do people enjoy risky(有危险的) activities like these?

Some people take risks simply because it makes them feel good. Psychologists(心理学家) say that this kind of explorers(探险者) are always looking for change and excitement. When people do something risky, a chemical(化学物质) in the brain creates a pleasant feeling. They love this feeling and want to experience it more.

Other people don't take risks for the feeling of excitement but to achieve a goal. Mike Fay went on a dangerous 2,000-mile special journey in central Africa. He worked to help save the wildlife there. Fay's journey helped create 13national parks.

For other people, such as extreme athletes (极限运动员), taking risks is part of their job. Psychologists say extreme athletes see the world differently. Not like most people, extreme athletes feel in control in dangerous situations. The danger can even help them. For example, skier Daron Rahlves says that being afraid makes him try harder to succeed.

Most of us are not extreme athletes or explorers. However, we still take risks in our lives. Some of us take social risks, such as speaking in front of a large group of people. Sometimes, we take financial risks, such as buying a house. And sometimes we take career risks, such as leaving a job or starting a business. Most people take risks in some areas of life, but not in others. What kind of risk-taker are you?

Anna always helps me{#blank#}1{#/blank#} my math. {#blank#}2{#/blank#}(在她的帮助下), I make great progress. I am good at English, so I always help her {#blank#}3{#/blank#}(learn)English. Sometimes we ask our teachers {#blank#}4{#/blank#}help. Today I go to Anna's home, I can't help{#blank#}5{#/blank#}(play) with her dog. Her mom cooks a lot of delicious food. She says to me,"Help {#blank#}6{#/blank#} (you) to everything you like!"

Imagine that you have woken up on the first day of your vacation. You enjoy a delicious breakfast, take a walk on the beach, and read the morning newspaper as you drink coffee. You are feeling happy and relaxed. But you may start to feel bored by the time the late afternoon comes around!

If you have ever felt like this, you're not alone. It turns out that having unlimited (无限的) free time is not always as great as we expected. What is the best amount (数量) of free time for our happiness?

Researchers tried to answer this question by surveying tens of thousands of people, collecting data (数据) on how they spent their time and how happy they were. After looking at the data, the research team found that having less than two hours of free time a day, was not enough to be happy. People with under two hours of free time a day usually had more stress. It means that they were simply too busy with work to get their happiness.

The fact that being too busy cuts happiness is true. It might lead to the answer that more free time is simply better. Surprisingly, having a lot of free time is not a panacea (灵丹妙药) for happiness. People surely get a certain sense of joy from finishing tasks. Having more than five hours of free time a day makes us lose the sense of joy. It is in fact cutting our happiness. But I think it is how we spend our free time that matters. When free time is used in more active ways, like playing a team sport, then five or more hours a day can keep of even produce happiness. However, spending five or more hours of free time alone can stop happiness.
