Einstein has to speak at an important science meeting.  On the way there, he tells his driver that looks a bit like him, "I'm sick of all these meetings. I always say the same things over and over!"

The driver agrees, "You're right. As your driver, I attend all of them, and even though I don't know anything about science, I could give the speech in your place. "

"That's a great idea!" says Einstein. "Let's exchange our places then!"

So they exchange clothes. As soon as they arrive, the driver dressed as Einstein goes on stage and starts giving the usual speech, while the real Einstein, dressed as the car driver, attends it.

But in the crowd, there is one scientist who wants to show off and thinks of a very difficult question to ask Einstein, hoping he won't be able to answer. So this guy stands up and cuts in the speech by raising his very difficult question. The whole room goes silent, holding their breath, waiting for the answer.

The driver looks at him, dead in the eye, and says, "Sir, your question is so easy that I'm going to let my driver answer it for me."

    For most people, summer holidays mean sun, sea and sand, {#blank#}1{#/blank#}. She had a holiday full of ice and snow. She and her family travelled across Greenland! Starting just above the Arctic Circle (北极圈), Sarah's family used dogsleds with kites to cross the world's biggest island.

    Sarah says {#blank#}2{#/blank#}. "There is only snow, ice, and more snow. " The family travelled 15 miles a day for 22 days, moving faster when strong winds pushed along their kites.

    Then the weather became a bit hot for the dogs to pull sleds during the day, {#blank#}3{#/blank#}. The Landrys lived in tents, ate dried food, and took baths with heated water. When they weren't travelling, they played with kites and made snowmen. Using their mobile phones, the family could send and get emails even from Greenland's ice cap! The road to the top was icy and dangerous.

    {#blank#}4{#/blank#}. "Icebergs (冰山) were so bright, just like the rising sun." said Sarah. Now she and her family have returned home, {#blank#}5{#/blank#}. Next holiday, they are going to the South Pole.

We live in the “computer age”. Today, it is more and more i{#blank#}1{#/blank#}for us to use computers. We use them at w{#blank#}2{#/blank#}, and we also use them at home. Adults use computers and c{#blank#}3{#/blank#}use computers, too. We often use the mouse to run all the work.

Slowly, you may f{#blank#}4{#/blank#}painful and numb(麻木的)in your hand, your wrist, your shoulder, and your neck. What's w{#blank#}5{#/blank#}with you? The mouse is eating your body f{#blank#}6{#/blank#}your hand to all. Some researchers explain that we feel painful b{#blank#}7{#/blank#}we often repeat the same action—click(点击). So we feel u{#blank#}8{#/blank#}little by little.

Nowadays, there are no best ways to s{#blank#}9{#/blank#}this problem. The only way is to change the way we use the mouse and the keyboard(键盘). When at work, we should have a break and e{#blank#}10{#/blank#}to keep our body healthy.
