How did we help to save our earth this week? Let me tell you.

       First, my family tried to save electricity. We never left the lights   (1)   when leaving the rooms. We   (2)   the TV when nobody was watching it. Mum only used cold water in the washing machine.

       Second, we started recycling（循环，回收）this week. We tried to write on   (3)   of our paper, not just on one side. We also divided (分成) our rubbish into   (4)   bags for bottles, paper and food. Mum kept the plastic shopping bags from the supermarket to use them again as rubbish bags.

       Third, my family started to save   (5)  . We stopped   (6)   long baths and had short showers   (7)  . We washed the toilet with used water. Mum and dad used less water to do the washing. My sister and I didn’t leave the tap running when we brushed our teeth.

At last, mum and dad began to save gas. Mum used to   (8)   us to school, but now my sister and I started riding our bikes to school. It’s hard work   (9)   good exercise! This week dad and a few of the people in his company also started to go to work in one car and share the   (10)  .

These are great ways to help protect our environment.

What is the sky? Where is it? How high is it? What lives above it? These questions are difficult   (1)  ,   (2)   they?

Is the sky blue?

The sky   (3)   no color. We know that there is air around   (4)   world. When planes fly, they need air   (5)   their wings. Planes can not fly very high because when they go higher, the air gets   (6)  If we go up about 1,200 kilometers   (7)   the earth, we find there is   (8)   air at all.

Maybe we can answer   (9)   of our questions now. The sky is space.   (10)   space there is only the moon and all the stars.

As we all know, the environment around us is getting  (1)   .Recently, a new lifestyle called low-carbon life is   (2)   every corner of our country. The meaning of low-carbon is  (3)   energy and no waste. There are many ways to promote it.

First, we should set up a no-car day every week in our school, because cars not only cause serious   (4)   pollution but also waste energy . On the no-car day , neither students nor teachers are   (5)   to drive to school. They can just walk or run. Use our   (6)   and enjoy the fun.

Second,we had better not use plastic bags any more. No one can stand the “  (7)   pollution “, so it is wise to use cloth bags which can be   (8)   again and again.

Finally, one thing that we should   (9)   is that every big thing comes from the small details. For example, we ought to turn off the lights the moment we leave, use both sides of the paper, and so on.

All in all, it weighs greatly for all of us to put the low-carbon lifestyle into practice. Just set our mind to these: no-car days, no plastic bags and no   (10)   . Let’s do it now.

If you go out sometimes at night, you will see the moon high up in the sky. The _  (1)  _ is far away from the earth. But it is our nearest neighbor in space. In 1969 two Americans _  (2)  _ it by spaceship. It is one of the _  (3)  _ exciting moments of that year.

 The sky looks black _  (4)  _ the moon and you will see the earth up in the sky. You will also see many, many stars.

 You _  (5)  _ find any living things there. It is too hot in the _  (6)  _ and too cold at night. And there is no air or water there. _  (7)  _ can live on it. It is difficult for men to _  (8)  _ on the moon. Everything becomes much higher. You can _  (9)  _ much higher on the moon than on the earth. If you throw a ball, it would fly very _  (10)  _. It is very interesting to walk on the moon!              

Trees are   (1)   to man in three very important ways. The first important way is that they provide man   (2)   food, wood and other products. Trees provide not only man with food, but also many animals with food.   (3)   trees many animals could not live on the earth. It’s not easy for man   (4)   on the earth,   (5)  . The second important way is that trees give us shade.   (6)   a hot summer day, people are eager(渴望) to have a rest under the shade of a tree after they have   (7)   a long way. You can imagine   (8)   important the shade of a tree is to man and to animals. The   (9)   important way is that trees help to prevent drought(旱灾) and floods. However, in many parts of the world, man has not realized the third important way. He has cut trees down in   (10)   numbers. In the end, he finds that he has lost the best friends he had.

A thousand years ago Hong Kong was covered by a thick forest. As more and more people came to  (1)  in Hong Kong, these trees were cut down and burnt. Now there is  (2)  forest left, though there are still some small areas covered with trees. We call these woods.

Elephants, tigers and many  (3)  animals were living in the thick forest. When people came to live in Hong Kong, the  (4)  began to die out. Early farmers grew rice and  (5)  pigs and chickens in the valleys. They cut down the trees and burnt them. They needed  (6)  to keep themselves warm in winter, to cook their food and to keep away the dangerous animals. Elephants quickly disappeared because there was not enough food for them.  (7)  did most of the wolves and tigers. Monkeys and many other animals soon     (8)  in the same way.

    You might think that there are no longer any animals in Hong Kong  (9)  in the zoos. But there are still about 36 different animals  (10)  there. One of the most interesting of Hong Kong’s animals is the barking deer. These are beautiful little animals  (11)  a rich brown coat and a white patch under the tail. They look like deer but they are much smaller. They are less than two feet  (12)  .They make a noise rather like a dog  (13)  .In Hong Kong the barking deer has only a real enemy—  (14)  .People hunt these little animals though it is illegal. There are now not many barking deer left. So it is important  (15)  people to protect wild animals.

When you go to the seaside, maybe you will notice(注意) that the wind very often comes from the sea to the land in the  (1)  part of the day, but in the evening, the wind blows in the opposite direction(方向).Why does this happen?

In the morning, when the sun   (2)   ,it begins to warm the land   (3)   the se a. The land  (4)   warm faster than the sea. So while the air above the sea is cool ,the air over the land   (5)  warmer. The air   (6)  the land rises and the cool air from the sea moves   (7)   the land.

When evening comes,   (8)  the sea and the land become cool, but the land cools more   (9)   than the sea. The wind now changes   (10)   direction.
