    Can you imagine astronauts' everyday life in space? They also need to eat,  1 , exercise and relax. They do the same things as us, but they do2 differently.

    On Earth, we put food on a plate and water in a glass. Gravity(重力) holds the food down and keeps the water in the glass.  3 there is almost no gravity in space, so food can float(漂浮) away, and astronauts must eat and drink4  .

    Sleeping is very different in space. Some astronauts like to float in the air, but most like to be in a 5bag. They tie the bag to a wall 6 they won't float away at night. Exercise is very important in space. On Earth, your legs 7 your body, but in space, astronauts float. So they do not use their legs often. This is very  8their legs, so they must exercise for thirty minutes every day.

    After a day's work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families  9  the radio. Sometimes they just enjoy 10 in the air.

    I can't remember when I started collecting litter. But it was when I got tired of 1 litter nearby that I realized no one else was going to pick it up.

    I live near a forest in Ohio, America. I can walk there  2 three minutes. I used to love going there to play with my dog. But one day there was 3 much litter there that I became very unhappy. I decided to clean up the forest, and I wanted to 4 happy when I went again. I made my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes 5  I started to pick up litter, my bag was full! There were cans, bottles, broken glass and newspapers in it.

    From then on, I 6  to the forest four times a year to pick up litter. I often stay there for three hours. It makes me feel 7 to do something for the environment. After each trip, I look through all the litter that I've collected. If 8  of it is recyclable（可回收利用的）, I'll keep it. I can't understand why people drop litter. But I will keep on picking it up  9they stop dropping it. I know I am only doing a small bit  10 the earth, but I still think it is important.

    Can you get free plastic bags from supermarkets now? I'm afraid you can't. Things have changed.

    Free plastic bags can't be used at shops and supermarkets in China, and people have to pay for plastic bags. Because our country tried to make litter1.

    The Chinese once used about 3, 000, 000,000 plastic shopping bags a day. They are2to break, most of them can be used only once. And some people throw them away here and there, they have caused pollution for the environment. If they are burnt, they may cause bigger troubles. For example, they may cause illness for us. So the Chinese people3to bring their own bags for shopping. Some students come up with a good idea. They make the shopping bags by 4. They use old clothes to make cloth bags, and send them to their parents as presents. They also ask their parents and friends to use cloth bags instead. They think it is their5to protect the environment.

Pandas live in the forests and mountains of Southwest China. They mainly 1 bamboo, and each panda 2 a lot of bamboo every day. The area of bamboo is becoming smaller for many different 3 , so pandas have 4 land to live5 . Pandas don't have many babies, and baby pandas often 6 . The situation is becoming very serious.

    Our government is working hard to save pandas. There are more than 30 natures reserves to protect pandas but these are not enough. The government has made a new plan  7 pandas. The nature reserves will be bigger and the bamboo will grow8  .Then the pandas will have enough food to eat and enough places to live in. Pandas born in the zoos may 9 live in the nature reserves.

Most people love pandas. The panda is one of the best-known  10  in the world. It is the symbol for the World Wide Fund for Nature.

    There was a small village near the mountain. There were a lot of trees in the mountain. People in the 1 always got something from it, such as animals and trees.  When they wanted to 2 a house, they cut down the trees. And they also killed the animals for 3 . Trees were very 4 in their daily life. They made tables, chairs 5   beds by cutting down the trees. In addition, when they 6 meals, they still used some trees for wood. However, they only cut down trees but 7planted new trees. So the trees were fewer and fewer; the animals were becoming 8 as well.

    One summer, it rained 9in the village. The rain lasted for about a week. The soil(土壤)and the stones on the mountain fell down and soon 10  the whole village. They finally knew they should not only cut down trees but also needed to protect them.
