Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries slowly.
You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
Your hands and wrists (手腕)
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something. 2) Keep your elbows at the same height as the keyboard. 3) Stop something and exercise your hands, wrists and fingers in a different way.
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should all be in front of your eyes. Your forearms, wrists, hands and the upper part of your legs should all be parallel (平行) to the floor. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and necks.
Enjoy your computer, but use it safely.

Thousands of years ago, people didn’t know that the Earth moved. They thought the sun really did move across the sky. The Greek god Helios was said to drive the sun around the sky with his chariot（战车）. But now, these ideas have all changed. Nowadays, it is the sun that drives our “chariot” around the sky.

So what does all this mean? Well, quite simply, there is now a plane （or “chariot”） that is powered by the sun. It has special parts in its wings. These parts absorb power from the sun. They absorb so much power that they can carry on flying at night. In the Greek myths（希腊神话）, Helios had to take a break at night. It seems we’re finally even more efficient than the gods themselves.

This plane is called Solar Impulse （“太阳驱动”号）. It will fly across the US in May. This is very important for the future of the world.

So why is solar energy so good for us? Well, other kinds of energy cause a few problems. If you live in China, you’ve probably noticed the pollution. This is caused by burning coal or gas to make energy. The heat and chemicals（化学制品）from this make things work. But if we use the heat from the sun, we don’t have to burn anything, and there’s no pollution.

Solar energy is not all there yet. It needs to be improved. But the best thing about it is that, unlike coal and gas, it doesn’t run out. Solar Impulse could keep flying forever. Well, actually, the sun will run out too, one day, but not for another 5 billion years. That’s a pretty long flight.

1.What does “chariot” really refer to in the last sentence of Paragraph 1?

A．The Earth.         B．The Greek god.     C．Solar Impulse.      D．Birds.

2.Which of the following is TRUE of Solar Impulse?

A．It can only fly at night.                    B．It has already flown across the US.

C．It is powered by the sun.                  D．It needs gas to work.

3.In the passage, what is mentioned as the cause of pollution in China?

A．Overpopulation.                        B．Burning coal or gas.

C．Using solar energy.                      D．Heavy traffic.

4.What does the writer mean by “That’s a pretty long flight”?

A．It takes a lot of time to get Solar Impulse going.

B．Solar Impulse moves very slowly.

C．Solar Impulse will be in use for a long time.

D．Solar Impulse has a long way to go to take the place of the sun.

5.The passage is most probably taken from___________.

A．a Greek myth      B．a science fiction     C．a story-book       D．a science magazine
