Do you know why you sleep? You may think it"s because you"re tired. Or perhaps you"ve been told sleep
is good for you. Yet no one knows exactly why or how people sleep.
Until the early 1950s, most scientists thought the body and brain rested during sleep. Then a scientist
watched people sleep. He noticed that during periods of between 5 and 30 minutes, sleepers" eyes made
rapid movements, as if they were watching something. He called these periods REM (Rapid Eye Movement)
sleep. He called periods when sleeper"s eyes did not move non-REM sleep.
Whenever the scientist woke people during REM sleep, they were having vivid dreams. Measurements
showed that sleepers" pulses (脉搏) went up quickly during REM sleep. Their breathing, heartbeat, and the
blood going to the brain also increased. Far from being a time of rest, sleep is a time when the body is hard
at work. Scientists still don"t know the reason for this. Some believe REM sleep makes learning easier.
Babies spend a lot of time on REM sleep. Because of this, some scientists believe that REM sleep helps
the brain grow. Others think REM sleep is a time for the brain to empty the day"s garbage.
One thing all the scientists agree on is that sleep is necessary. Without enough sleep, people make
mistakes. Most car accidents happen during the early morning hours, when people are sleepiest.
B. sleep
C. increase

D. Paragraph 4
B. about the scientific research of REM sleep
C. about how to empty the day"s garbage
D. that our body is good at work when sleeping
B. young people can experience REM sleep

In Japan, people have to pay for their garbage. If they have a lot, or their garbage is difficult to treat,
they have to pay more. They also have to pay for things they no longer need, like old TVs and fridges. This
makes people think before they throw away.
There are few garbage cans in Japanese streets. People take their garbage home and sort through it
carefully. They also have different ways of treating different kinds of garbage. People turn old chopsticks
into paper. They burn some garbage to make fertilizer (肥料). People even use garbage to make more land
area.
Japan has set a good example to the rest of the world. If people in every country did the same, we
would be able to do something about our environmental problem.
What can we do to help the environment? Here are some ideas.
·Reduce!
Check it out. Buy products with less packaging (包装). Buy less and create less garbage. We shouldn"t
buy things we don"t need.
·Reuse!
Be creative and make use of garbage. For example, you can make a photo frame (边框) out of buttons,
and other small pieces of garbage.
·Recycle!
Ask your family and friends to use recycled products. Be helpful. Is there a recycling center near
your home? If so, ask your family and neighbors to recycle.
B. 丢弃
C. 处理
B. what we should do to help the environment
C. different kinds of ways to make use of garbage
B. Three.
C. Four.
B. Go shopping more often and buy things we don"t need.
C. Ask our family and friends to use recycled products.
B. There are many garbage cans in Japanese streets.
C. We can recycle the garbage by burning all the buttons.
Everybody dreams. But only some people remember their dreams. Our dreams often include all the senses-smells, sounds, sights, tastes and things we touch. We dream in colour. Sometimes we dream the same dream over
and over again. These repeated dreams are often unpleasant. They may even be nightmares-bad dreams that
frighten us.
Early in the twentieth century, two famous scientists developed their personal ideas about dreams.
Austrian psychiatrist Sigmund Freud published (出版) a book called "The Interpretation (诠释) of Dreams"
in 1900. Freud believed people often dream about things they want but can"t have. These dreams
often have something to do with sex and aggression (侵犯行为). Swiss psychiatrist Carl Jung worked
closely with Freud for several years, but he believed dreams could help people grow and understand
themselves. He believed dreams provide solutions (解决办法) to problems we face when we are awake.
He didn"t believe dreams hide our feelings about sex or aggression. Today we know more about the science
of dreaming because researchers can take pictures of people"s brains while they are sleeping.
Other researchers are studying how dreaming helps our bodies work with problems and very sad emotions. Robert Stick gold is a professor of psychiatry at Harvard University in Massachusetts. Doctor Stick gold says
that when we dream, the brain is trying to make sense of the world. He does not agree with Sigmund Freud
that dreaming is the way we express our hidden feelings and desire (愿望).
Scientists believe it is important to keep researching dreams. Doctor Stick gold says it has been more than
one hundred years since Sigmund Freud published his important book about dreaming. Yet there is still no agreement on exactly how the brain works when we are dreaming or why we dream.
B. express all that we think in our mind
C. include few senses and things we touch

B. think dreams always hide someone"s feelings about sex or aggression
C. study dream and dreaming and have their own ideas
D. have the same idea that people often dream about the things they want
B. Freud developed the idea that dreams are expressions of people"s hidden feelings
C. scientists have known quite well why we dream because they can take pictures of our brains
D. other researchers have discovered how dreaming helps our bodies work with problems and
very sad emotions
B. The Ways of Dreams.
C. The Solutions to Dreams.
D. The Mystery (奥秘) of Dreams and Dreaming.
eating well, getting enough exercise, and having a healthy weight. Let"s read the following rules. They can
help you stay healthy.
1. Eat a variety of foods, especially fruit and vegetables. We all know that eating fruit and vegetables can
help us stay healthy, but many of us only eat our favorite foods. Remember that we can only get the
nutrition (营养) we need by eating different kinds of food, especially fruit and vegetables.
2. Drink water and milk most often. Everyone knows that water is important. Besides that, kids need plenty
of calcium (钙) to grow strong bones, and milk has a lot of it. Every day, you should drink at least three cups
of milk (1300 milligrams of calcium), when you are 9 years old or older. You should also try to have less
sugary drinks, like soda and coca. They include a lot of sugar. Sugar just includes calories, not important
nutrition.
3. Listen to your body. When you are eating, notice how your body feels. When your stomach feels
comfortably full, stop eating. Eating too much makes you feel uncomfortable. If you do it too often, it can
make you unhealthy and fat.
4. Limit (限制) screen time. What"s screen time? It"s the amount of time you spend watching TV, movies,
and playing computer games. The more time you spend on these sitting-down activities, the less time you
spend playing sports, like basketball, and doing other activities like bike riding and swimming. Try to spend
no more than 2 hours a day on screen time.

| Rubbish is a major kind of environmental pollution. Each person produces about two kilograms of rubbish in our homes a day. And this is only a small part of all the rubbish we produce. We also create waste in industry. Have you wondered what happens to the rubbish? Most of it is buried (填埋) in landfills or burned. Less than 25% of our waste is recycled (回收利用). A landfill (垃圾填埋厂) is carefully designed and it is built into or on top of the ground. Rubbish buried in landfills is cut off from the surrounding environment (groundwater, air, rain, etc). One problem with landfills is that they cover a lot of land space. If they are not well-built, there is a high risk of polluting the land and water. Some people also say that landfills remove materials for ever. As a result, the materials that can be reused are wasted. Burning rubbish in factories is another way to cut out waste. Burning reduces 95% of the waste. And if poisonous materials are removed, and burning is completed at controlled temperatures, it"s possible to do so without causing too much pollution. Some factories could even produce electricity from the burning process. Not all of the rubbish can be burned, so we have to separate (分类) it before we burn it. However, separation costs a lot of money. Another problem with burning rubbish is that what is left after burning is poisonous.How to safely deal with it is a continuing problem. Before the mid-20th century, landfills were the main way to deal with waste.In the late 20th century, other ways like recycling have been introduced to help reduce global pollution. | |||
