The earth has warmed by about half a degree (0.5) over the last 100 years. It could be getting warmer
on its own, but many scientists think that people are making the Earth warmer by making a greenhouse
effect (温室效应). The greenhouse effect is important. Without it, the Earth would not be warm enough
for us to live on. But just a little warmer than it is now could cause problems for humans, plants and animals.
     Many of things we do every day can change the Earth's temperature by sending greenhouse gases into
the air. We send greenhouse gases into the air when we watch TV, turn on lights, dry hair, play video games,
wash or dry our clothes or drive cars. The rubbish from factories and homes also produces greenhouse gases.
     Even a small change in temperature can affect our weather. This can cause changes in the sea levels,
the air, flooding, and our fresh water.
     The change in the temperature can also cause changes in the living places for animals and plants,
endangering many animals.
     Global warming (全球变暖) is a big problem, and every little bit we do can help. We can save electricity.
We can save energy in other ways such as by taking buses or walking rather than driving cars. We can
recycle to reduce the rubbish and save natural resources such as trees, oil and metals. We can buy products
that don't do bad to the environment and we can turn to solar energy. Remember the little bit that you do
will bring a better world.

     Do you sweat, chew (嚼) your pencil, and feel butterflies in your stomach as your teacher hands out
a test? A lot of people get freaked out (兴奋) when it is time to take a test. It is natural to feel some stress
(压力) about taking tests. In fact, sometimes a little adrenaline (肾上腺素) is a good thing to jump-start you.
Here are some tips for taking tests:
     ● First, be sure you have studied properly. It sounds like a no-brainer, but if you are sure of the information,
you will have less reason to be worried.
     ● Get enough sleep the night before the test. Your memory recall (使想起, 回想) will be much better if you
have had enough rest. In a scientific study, people who got enough sleep before taking a math test did better
than those who stayed up all night studying.
     ● Listen closely to any instructions. As the teacher hands out the test, be sure you know what is expected
of you.
     ● Read the test through first. Once you have the test paper in front of you, read over the full test, checking
out how long it is and all the parts that you are expected to complete. This will allow you to estimate (估计)
how much time you have for each part and ask the teacher any questions. If something seems unclear before
you start, don't panic: ask.
     ● Focus (集中) on addressing each question one by one. As you take the test, if you do not know an answer, do not obsess (使困扰) over it. Instead, pass over the question and come back to it after you have answered
other questions.
     ● Relax. You might need a mini-break if you are so nervous that you blank out. Of course you cannot get
up and move around in the middle of a test, but you can wiggle (摆动) your fingers and toes, take four or five
deep breaths, or picture yourself on a beach or some other calm place.
     These tips should help most people, but some can get serious test-taking fear. You may need to ask a
teacher or counselor for help if you are one of them.

     Dreams are expressions of thoughts, feelings and events that pass through our mind while we are sleeping.
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 (精神病专家) Sigmund Freud published (出版) a book called "The Interpretation 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 desires.
      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.

A. Other researchers have discovered how dreaming helps our bodies work.
B. Freud developed the idea that dreams are expressions of people's hidden feelings.
C. Carl Jung thought dreams provide solutions to problems we face when we are sleeping.
D. Scientists have known well why we dream because they can take pictures of our brains.

4. Which would be the best title for the passage?

A. The Explanations of Dreams.

     What would you be like if the entrance exam to senior high school was tomorrow? Peaceful and happy
as usual? Or, would you become worried and uneasy?
     "I was surprised at how I could get angry so easily with my parents before a big exam," said Junior 3
student Wang Yangqian from Hefei. "I couldn't fall asleep even after I'd been in bed for two hours."
    Not only exams but also other things, like a big game, can make you different from how you are usually.
    You may act differently because you are stressed out. Stress is what you feel when you are worried or
uncomfortable about something. Usually your hands get wet and your heart beats faster. You feel stressed
because you might ask too much of yourself sometimes. Or, your parents, teachers or classmates put too
much pressure on you. This can make you worried. But being stressed is not always a big problem. Everybody,
even sports stars, can get a little worried before a big game.
     Some kinds of stress are good. Good stress might show up when you're called on in class or when you
have to give a report. This kind of stress can help you get things done well. You may do a better job in your
book report if the anxiety pushes you to do more work before you read it to the class.
     Sometimes stress can turn into something bad if you keep having stressful feelings for a long time. This
kind of stress isn't going to help you. It can make you sick. You may have trouble paying attention at school
and forget things easily.
     So, remember to stay relaxed. It won't be the end of the world, even if you don't pass the exam.

     Qiu Baoxing, Vice-minister of Construction of China, has said that our country is "facing a more serious
water crisis (危机) than any other country in the world." And the Chinese government would raise the cities'
waste water treatment rate from 45.6% to 60% in five years.
     "Because water plays such an important role in our country's economy (经济) and people's life, we must
pay much attention to it. We have to solve the problem before it is too late," warned Qiu. He said China should
learn lessons from developed countries. They have paid heavy costs in solving the environmental pollution."
We must take action before the city water ecosystem collapses (生态恶化)," Qiu said.
     Qian Yi, professor of environmental engineering, said that two problems-the shortage of water resources
and the pollution of water cause China's water crisis. He said China's present water availability is still low,
about a fourth of the world average level. By 2030, the number will drop much. What's worse, among China's
seven main rivers, five have been seriously polluted. The worst is the Haihe River near Beijing and Tianjin.
     Qiu said the government is improving the city water, controlling strictly water quality and safety. The

     Is human blood all the same? "Yes." You may say. "It's all red."
     Well, it's not as simple as you might think.
     Blood is made up of different parts, such as red blood cells (红血球), white blood cells and platelets (血小板).
     Two chemical molecules (分子) on the red blood cells make people's blood different. Scientists mark one
molecule "A" and the other molecule "B". According to which and how many molecules are on the red cell,
scientists divide blood into four types: A, B, AB and O.
     Your blood type will stay the same all your life.
     Scientists have been wondering if there are some links (联系) between people's blood types and their
personalities, but they are not certain.
     But some say that people with the same blood type may have things in common.
     What's your blood type? Do you have family members or friends who are of the same type as you?
Read the following. 
     People with Type A: They look peaceful from the outside. But they ask too much of themselves that
they may be very nervous inside. They get happy or sad easily. Sometimes they are shy but always very
careful. They can easily win people's trust.
     People with Type B: They have strong minds. Once they start a task, they don't give up easily. They'll
try their best to finish it and do it well. Type B people always try to make themselves different from others.
They want to do things in their own way.
     People with Type AB: They are maybe the strangest among all blood types. They can be both open and
shy, noisy and quiet at the same time! They are responsible and always ready to help others.
     People with Type O: They are open and good at making friends. They always start tasks but don't always
finish them. They have lots of new ideas and love to be the centre of attention. They always strongly believe
in themselves.
