Unit 13 We're trying to save the earth! 知识点题库

    One fresh sunny day, while I was swimming in the water, I felt something special going through my gills(鳃).It was a different kind of water. I also found many of my friends became sick. Some of them were dying. I was starting to worry because I didn't want to get sick or die. I was also thinking about what I should do to save my friends, so I decided to do some research for my underwater life.

    My research started. At first, I noticed there were many bottles, cans and other kinds of rubbish in the water. Then I went on… I got closer and then I tasted many different kinds of liquid(液体).(A)To my surprise, I noticed a man pouring some liquid into the water. Others also saw him doing so and they decided to follow him. I hated it! I wish I could have told them that it was killing us!

    I think it is so stupid for people to do this to the earth that they are living on! I can't understand (B)      they are doing this. Humans should stop throwing waste into the lakes or rivers. I want to have a normal life with my friends. People should stop being so selfish and care about the environment. If they do that, everyone will be fine and will have nothing to worry about. I suggest they follow my words. If so, I believe everyone will be able to live a happy life.

—Oh, sorry, Morn.

    Philip is a school boy. On his twelfth birthday, he decided to give up eating 1.

    "I don't think it's right to eat animals," he said. "They live on the Earth just like us and they are our friends." Philip's parents were not happy about that. "You are a growing boy," his mother said "You need meat. Don't you want to become healthier and 2?" His mother put some 3, rice and carrots in front of him. "I want you to eat all your food now," she said. "Don't 4 anything." Philip didn't want to make his mother sad. But he ate only the rice and the carrots without touching the beef.

     "You're a silly boy!" said his father 5. "I'm getting very angry with you."

     "I'm sorry, Mum and Dad," answered Philip. "I don't want you to be sad or angry. 6 I really don't want to eat any meat. "

     "Then have some fish, dear," said his mother.

     "Oh no, I can't!" cried Philip. "Fish are living things, too.

     "Well, you can't have 7 to eat at all if you don't eat any meat or fish," said his father.

    The next morning Philip got up hungry. His father walked to the 8 with him and asked to see the teacher. "Is this what you teach the students at school" he asked the teacher. "Philip 9 to eat meat at home. He doesn't listen to what I say. "

    "I don't agree with Philip," replied the teacher. "But I think he is 10 to do what he thinks is right. We teach the students to do that."

    Need to buy something? Why go to a store? Buy it on the Internet! Need it now? Why wait? Ask to receive it the next day! Each day, more and more people try on-line shopping. In fact, online sales have doubled in the last ten years. But not everyone is excited. Some scientists now say that online shopping is bad for the environment.

    People are surprised to hear this." They think, I don't need to drive, and the business doesn't need to build a store, so there will be less pollution," says Nuria Prost, an environmental scientist. "But it is not so simple. In fact, online shopping is wasteful. It also adds to air pollution."

    In truth, the Internet is not always as good a friend to the environment as it seems. For example, most people thought that the Internet would help offices use less paper and other materials. But paper use increased by33percent between 1986 and 1997."Online shopping could have similarly harmful results," says Nevil Cohen, a researcher of environmental science. Part of the problem is what people are buying these days. In the past, people bought things on the Internet that did not require much packing material, such as books and clothing. But now people also shop online for large, heavy pro ducts such as televisions, computers, chairs and tables. These products need to be packed in lots of plastic and paper. This creates a lot of waste.

    Another problem caused by online shopping is air pollution. When customers buy products and ask to receive them the next day, online businesses often have to send them by air. Airplanes use much more oil than cars and produce more carbon dioxide（二氧化碳）. When people buy a lot of different things from different online businesses, this creates even more travel by airplane.
    Online product returns are also a problem. For example, an online shoe store may allow customers to return shoes for free if they are wrong size. This doubles the packing materials and number of airline trips required to sell one pair of shoes.

    "If people want to protect the environment, they need to think before they shop," says Prost. "People need to ask themselves: Is this exactly what I want? Do I really need it tomorrow, or can I wait?" Online stores can also ask customers to pay money for returns. This may make people shop more carefully." Online shopping is fast and easy, "says Prost," but we can't forget the harmful result it has caused to the environment."

Don't your old books. Give them to me!

Waste materials should instead of being thrown away.
