  • Hundreds of years ago, life was harder than it is today. People didn’t have modern machines. There was no medicine, either.
    Life today brings new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and we become angry more easily. Air pollution is the most serious kind of pollution to all living things in the world.
    Cars, planes and factories all pollute our air every day. Sometimes the polluted air is very thick. People cannot see the sky clearly.
    Many countries are making rules to fight against pollution. Factories now must clean their water before they throw it away. And they mustn’t let dirty smoke go into the air.
    There are many things we can do to fight against pollution. We should put waste things in dustbins and do not throw them on the ground. We should go to work by bike or on foot instead of taking a car or a bus. If there are fewer people driving, there will be less pollution.
    Rules are not enough. We should do our best to fight against pollution.

  • Today there are 6.4 billion people on the earth. By the year 2050 there may be 12.5 billion . There are a lot of people to feed. We need more  and more food.
    One way to produce more food is growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic(遗传的) material. Foods from plants grown in this way are called genetically modified(改变的) foods, or GM foods.
    By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases; a kind of rice is being prepared , for example , which stops people becoming blind.
    Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.
    GM plants are not natural. No one knows how good or bad they are,. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people , then hurt them or their children later. But both rich and poor countries are interested in their use, and they are not going to go away. In 2050, we may think differently about them.
    【小题1】GM foods are made by                 
    A. farmers            B. workers      C. scientists          D plants
    【小题2】What are the good things about GM foods  ?
    A. They make plants strong against diseases.   B. They are unnatural.
    C. They can help in human diseases.            D  Both A and  C.
    【小题3】GM foods        .
    A. are a quick way to produce food    B. grow in the wild 
    C. are safe                           D are grown only in rich countries
    【小题4】Why do some people not like GM foods?
    A. They are not useful.       B. They are not helpful.
    C. They are not natural.      D  They are not cheap.

  • The population of the Earth is growing faster. It is important that we look after the Earth. We need it!
    The Earth gives us a lot of things. We also give the Earth a lot, but some of the things are not good.
    In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food for other animals or plants. However, animals can’t get food from many of the things that we ‘give’ the Earth. Animals and plants can’t eat metal, plastic and glass. These things will stay in the ground for many, many years.

    Some rubbish is very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals in the water, the plankton(浮游生物) can die. If there isn’t any plankton, many animals have nothing to eat.
    So what can we do? Don’t leave any rubbish in the countryside! Don’t make so much rubbish!

  • When US student Olivia Priedeman, 17, woke up one morning, she thought she had had a dream about making plans with a friend.
    But it wasn’t a dream. Her phone showed that during the night, Priedeman had read a text message from her friend. She did it while she was fast asleep.
    Reading and sending text messages while asleep—called “sleep texting”—is an unusual sleep behaviour, similar to sleepwalking. It’s also a growing concern(关心的事) among doctors: young people can’t live without their cell phones.
    One in three teenagers sends more than 100 text messages a day, according to the Pew Internet & American Life Project. And at least four out of five teenagers said they sleep with their phone on or near their bed.
    Elizabeth Dowdell, a professor at Villanova University in Pennsylvania, has studied sleeping texting. She said that having a phone nearby all night is a big part of the problem.
    Andrew Stiehm, a sleep medicine expert with Allina Health in Minnesota, agrees. It’s possible for the part of the brain that controls motor skills (动作技能) to wake up, while the part of the brain that controls memory and judgment(判断) may be still asleep. That’s why some people can perform basic movements ---such as walking, talking, texting or even driving—while they’re sleeping. Some of Dowdell’s students said that they’re disturbed by their nighttime texting behavior. But because sleep texting is unconscious, it’s a difficult habit to break. Dowdell said she knows of some students who wear socks on their hands to keep themselves from texting.
    Marjorie Hogan, a doctor at Hennepin County Medical Center in Minneapolis, Minnesota, suggests keeping all electronic devices(电子设备) outside the bedroom at certain times.

  • Air is all around us. At the time we are born, air is around us everywhere .We live in air.
    All living things need air. Living things cannot live without air. We can go without  food or water for a few days, but we can't live a few minutes without air. We take in  air. When we are working, we need more air. When we are sleeping, we need less (少量的)air.
    We live in air but we cannot see it. We can only feel it. We can feel it when it is moving. Moving air is called wind. How can you make air move? Here is one way. Take an open book in your hands in front of your face. Close it quickly. What can you feel? It is air.

  • Do you know why different animals or pests(害虫)have their special colours? Colours in them seem to be used mainly to protect themselves.
    Some birds like eating locusts, but birds cannot easily catch them. Why? It is because locusts change their colours together with the change of the colours of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
    If you study the animal life, you’ll find the main use of colouring is protecting themselves. Bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colours much like the tree.
    Have you ever noticed an even more strange act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spreads over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn’t strong at all.
