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.

    The universe is really mystical(神秘的). Scientists have done lots of study about it but there is still much they haven't discovered.

    Scientists think that there 1 life on the earth for many many years. However, we haven't found life on any other planets 2

    There are eight planets going around the sun. The earth is one of them. There are humans, animals, plants and many other kinds of life on the earth. There is water and air, too. And compared to the other planets, the earth is not too 3 or too cold. None of seven other planets has av. environment like that of the earth.

    The sun and its planets are called the solar system, and our solar system is a small part of a 4 larger group of stars and planets, called the Galaxy or the Milky Way. There are 5 stars in the Galaxy, and our sun is only one of them.

    Scientists have also discovered many other galaxies in the universe. Their light has to travel for many years to reach us. So 6 is the universe? It is impossible to imagine.

    Scientists have sent spaceship to the planet Mars 7photos. They have even sent spaceships to travel outside 8 . However, no spaceship has traveled 9 to reach other stars in our Galaxy.

    When we see stars twinkling(闪耀) in the sky at night, we may think a lot:10 so many stars in the universe, is there life out there in space? If there is life on other planets, what life will be like there? What transports do they use to travel? Why don't they visit us? We do not know the answers…

    Do you often drink bottled drinks? Of course 1  is so cool to get a cold one right out of the fridge, right? But all those plastic bottles use a lot of oil and  2 the environment. Americans buy 3 bottled water than any other nation in the world. In order to make all these bottles, 17 million barrels (桶) of oil  4up. That's enough oil to keep a million cars going for twelve months.

    Many people choose 5 the bottles away after having the bottled drinks. In fact, instead of going out with the trash, plastic bottles can be turned into carpeting for clothing. Remember this: Recycling one plastic bottle  6save enough energy to power a 60-watt light bulb for six hours.7 , for every six water bottles we use, only one is recycled. The rest are sent as garbage (垃圾). Or, even worse, they end up 8  trash on the land or in rivers and oceans.

    So why don't more people drink water from the kitchen? Some people drink bottled water 9 they think it is better for them, but that's not true. The chemicals in the bottles themselves may get into the water which can do harm to people.

    So next time when you have drinks or water, please  10 to use a glass at home or carry water in a steel bottle. And if you want to do something more, try to collect plastic bottles and send them for recycling.

    As we know, life today has many problems. One of the biggest is 1, such as water pollution, air pollution, 2 pollution and so on. Water pollution makes our rivers and lakes 3. It kills fish and pollutes our drinking water. Air pollution is the most serious kind of pollution. 4 bad for living things in the world. Noise pollution 5 us talk louder and become angry 6.

    The Earth is 7 home and we must save it. We can't 8 rubbish here and there. We should go to work and school 9 bus or with our friends in the same car. Everybody 10 save the Earth.

    Hello, human friends. My name is Nick. I am a turtle (海龟). I have lived in the 1 for over half a century. In general, turtles can 2 to be more than 100 years old. 3many of my friends are now dying from one thing: plastic(塑料).

    Human beings use too 4 plastic. When you throw plastic away, it doesn't just disappear. Over 90 percent of the world's plastic doesn't get recycled(回收). A lot of plastic 5in the ocean. Most of my friends do not know the danger of plastic. They think it is 6. But in fact, plastic is 7. Around 30 percent of my friends have plastic in their body. I have plastic in my body, too. Plastic is also 8 other sea animals. Last month, one of my friends died after eating 80 plastic bags. I feel so 9 about it.

    My human friends, please 10 using too much plastic. Maybe one plastic bag or one coffee cup won't make a difference. But when seven billion people all start to use less plastic, it will make a big difference.
