We live on Earth. It's our home. But how much do you know about it? Let me tell you something about our Earth.
The Earth is like a huge ball. Like the other seven planets, the Earth is running around the sun. It's the third nearest one to the sun. It takes the Earth about 365 days to run around the sun. At the same time, the Earth is going around itself. If you are in space, you can see lots of white clouds over the surface of the Earth. Through the clouds, you can see the blue colour of the oceans, and the brown colour of the land. About 70% of the Earth is covered with water.
Why do we have day and night? When the half of the Earth is facing the sun, it's daytime. As the Earth turns, and this half is away from the sun, night is coming. And it's daytime for the other half.

The last Monday in March is an important day in China. It is a day for school safety education. This year, the day falls on March 25. It helps students learn more about safety and make sure they are safe. What are some accidents at school? How can you keep yourself safe? Take a look!
The main accidents at school are stampedes(踩踏), earthquakes and fires.
A stampede always happens in crowded places. When students around you begin to push, stand there and try to hold onto something. If you fall down in the crowd, put your hands around your head. Move to one side, and bend(弯) your body and legs.
Earthquakes happen all over the world. When you feel everything is moving, quickly get under a desk and hold on, according to China Earthquake Administration(地震局). If you are outdoors, find a place away from buildings, trees, and power lines(电线).
When there’s a fire, leave the classroom quickly. It’s better to put something wet over your mouth and nose. This way, you won’t breathe in smoke. Many people die in a fire, not because of the fire, but smoke. It makes them cough and they can’t breathe. That’s very dangerous! So when you want to get out, you should make yourself lower to the floor. Then you can breathe some fresh air.在

A Nepalese teenager had made a £ 23 solar panel (太阳能电池板 ) using human hair.
Milan Karki, who is 18 years old and lives in a village, used human hair to replace (代替)silicon, which is a common but expensive part of solar panels. By using hair as a replacement, Karki says that solar panels can be produced for around £ 23.
Karki got the idea from a Stephen Hawking book, which explained how to create energy from hair. The device (设备) that Karki has showed can produce 18w of energy -- plenty to charge a mobile phone.
"Half a kilo of hair can be bought for only 16p in Nepal and last a few months; but a pack of batteries (电池) would cost 50p and last a few nights," according to The Daily Mail.
The solar panel is easy to service as the hair is easy to replace. Karki has now sent out several devices to other places near his home for testing. He said, "First I wanted to provide energy for my home, then my village. Now I am thinking for the whole world." Karki wanted to use human hair because it is
| A．beautiful | B．long |
| C．cheap | D．soft |
What does the word charge mean in Chinese?
| A．为……改变 | B．为……付款 |
| C．为……充电 | D．为……美容 |
From the passage we know Karki is
| A．handsome and clever |
| B．clever and helpful |
| C．lazy but clever |
| D．handsome and helpful |
What is the passage mainly about?
| A．Making a mobile phone with human hair |
| B．Making a mobile phone with a new idea. |
| C．Making a solar panel with silicon. |
| D．Making a solar panel with human hair. |
