Paragraph 1
     Scientists have learned a lot about the kinds of food people need. They say that there are several kinds of
food that people should eat every day. They are: (1) green and yellow vegetables of all kinds; (2) citrus (柑橘)
fruits and tomatoes; (3) potatoes and other fruits and vegetables; (4) meat of all kinds,fish and eggs; (5) milk
and food made from milk; (6) bread or cereal (谷类), rice is also in this kind of food; (7) butter, or something
like butter.
Paragraph 2
     People in different countries and different places of the world eat different kinds of things. Foods are
cooked and eaten in many different kinds of ways. People in different countries eat at different times of the
day. In some places people eat once or twice a day; in other countries people eat three or four times a day.
Scientists say that none of the differences is really important. It doesn't matter whether foods are eaten raw
(生的) or cooked, canned or frozen. It doesn't matter if a person eats dinner at four o'clock in the afternoon
or at 11 o'clock at night. The important thing is what you eat every day.
Paragraph 3
     There are two problems, then, in feeding the large number of people on the earth. The first is to find some
ways to feed the world's population so that no one is hungry. The second is to make sure that people
everywhere have the right kinds of food to make them grow to be strong and healthy.

                                              How to Build a Windbreak to Protect Soil
     Farmers use different kinds of soil conservation methods to protect their land against damage from farming
and the forces of nature. One important form of soil conservation is the use of windbreaks.
     Windbreaks are barriers (栅栏) formed by trees and other plants with many leaves. Farmers plant them in
lines around their fields.
     Windbreaks stop the wind from blowing soil away. They also keep the wind from destroying or damaging
crops. They are very important for growing grains, such as wheat.
     There have been studies done on windbreaks. Studies in parts of West Africa, for example, found that grain
harvests can be twenty percent higher in fields protected by windbreaks. This was compared to fields without
such protection.
     Windbreaks can help protect a farmer's land. However, windbreaks seem to work best when they allow a
little wind to pass through. If the wall of trees and plants blocks the wind completely, then violent air motions
will take place close to the ground. These motions cause the soil to lift up into the air where it will be blown
away.
     For this reason, a windbreak is best if it has only sixty to eighty percent of the trees and plants needed to
make a solid line.
     An easy rule to remember is that windbreaks can protect areas up to ten times the height of the tallest trees
in the windbreak.
     There should be at least two lines in each windbreak. One line should be large trees. The second line, right
next to it, can be shorter trees and other plants with leaves. Locally grown trees and plants are best for
windbreaks.
     Windbreaks not only protect land and crops from the wind. They can also provide wood products. These
include wood for fuel and longer pieces for making fences.

1. What does the underlined word "conservation" mean in the passage?

A. Damage.
B. Protection.
C. Force.
D. Harvest.

2. What do farmers use windbreaks for?

A. To keep animals from getting into the fields.
B. To keep water in their fields.
C. To prevent their soil blowing away and wind destroying the crops.
D. To get more trees.

3. According to the passage what is a best windbreak?

A. One with no breaks between trees or plants.
B. One with plants which have many leaves.
C. One with certain breaks between trees and plants.
D. One with as many trees or plants as possible.

4. What's the purpose of the writer in writing the passage?

A. To tell us why farmers build windbreaks around the fields.
B. To tell us how to get a higher harvest.
C. To let us know there are usually windbreaks around the fields.
D. To tell us how important it is to keep soil and crops.

     Want a glance of the future of health care? Take a look at the way the various networks of people about
patient care are being connected to one another, and how this new connectivity is being exploited to deliver
medicine to the patient-no matter where he or she may be.
     Online doctors offering advice based on normal symptoms (症状) are the most obvious example.
Increasingly, however, remote diagnosis (远程诊断) will be based on real physiological data (生理数据) from
the actual patient. A group from the University of Kentucky has shown that by using personal data assistance
plus a mobile phone, it is perfectly practical to send a patient's important signs over the telephone. With this
kind of equipment, the cry asking whether there was a doctor in the house could well be a thing of the past.
     Other medical technology groups are working on applying telemedicine to rural (countryside) care. And at
least one team wants to use telemedicine as a tool for disaster need-especially after earthquakes. On the whole,
the trend is towards providing global access to medical data and experts' opinions.
     But there is one problem. Bandwidth (宽带) is the limiting factor for sending complex (复杂的) medical
pictures around the world-CT photos being one of the biggest bandwidth users. Communication satellites may
be able to deal with the short-term needs during disasters such as earthquakes or wars. But medicine is looking
towards both the second-generation Internet and third-generation mobile phones for the future of remote
medical service.
     Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With
the falling price of broadband communications the new technologies should start a new time when telemedicine
and the sharing of medical information, experts' opinions and diagnosis are common.

1. The writer chiefly talks about _____.

A. the use of telemedicine
B. the on-lined doctors
C. medical care and treatment
D. communication improvement

2. The basis of remote diagnosis will be _____.

A. personal data assistance
B. some words of a patient
C. real physiological information
D. medical pictures from the Internet

3. Which of the following statements is true according to the text?

A. Patients don't need doctors in hospitals any more.
B. It is impossible to send a patient's signs over the telephone.
C. Many teams use telemedicine dealing with disasters now.
D. Broadband communications will become cheaper in the future.

4. The" problem" in the fourth paragraph refers to the fact that _____.

A. bandwidth isn't big enough to send complex medical pictures
B. the second-generation of Internet has not become popular yet
C. communication satellites can only deal with short-term needs
D. there is not enough equipment for spreading the medical care

      A new computer treatment is being used to deal with obesity in children. Connected to a small dining set,
consisting of (包括) scales and a plate, a mini computer teaches children how to eat and reminds them when
to stop.
      "In very fat people, hunger signals from the stomach to the brain stop functioning. But the new computer
system teaches the children how to receive these messages again," says Dr. Julian Hamilton-Shield, the Bristol
University senior lecturer leading the treatment trials.(实验).
      The computer, called a Mandometer, records and stores the weight loss from the plate when children eat.
As the food is leaving the plate, a curve (曲线) is produced on the computer screen suggesting whether the
child is eating too quickly.
       "Children with weight problems often eat too quickly. We want them to eat steadily (稳定地) and slowly
and the system teaches them to slow down. It's a bit like retraining," says Hamilton-Shield.
       Obesity now represents (代表) one of the major threats to the future health of children. About one in five
boys and one in four girls aged two to fifteen in England are overweight. But so far no treatments have proven
effective in treating children. 
      The Mandometer was developed in Sweden, but at present is experiencing further development at the
University of Bristol, with $ 224,400 in funds from BUPA-a global health and care organization. The system
could be on the market in two years' time. At first, it would be managed by medical clinics (诊所).

1. The text is mainly written to explain ______.

A. how a new computer treatment dealing with obesity works
B. why child obesity becomes a topic of people
C. how to lose weight with the help of computers
D. why a computer is effective (有效的) in dealing with child obesity

2. The word "functioning" in paragraph 3 probably means ______.

A. eating
B. working
C. lasting
D. losing

3. Obesity threatens the health of children, which ______.

A. people have not cared about
B. is nothing compared with other diseases
C. has led to many deaths
D. is very serious

4. What can we learn from the text?

A. The Mandometer will be put into market once it proves effective.
B. The Mandometer is cheap enough for every family to afford.
C. The Mandometer is still not perfect.
D. Slow eating is sure to make people lose weight.

     About 97% of the world's water is salty and is found in our oceans and seas. But, as we can't drink
seawater, how can it be important?
     Every part of our seas and oceans contains an amazing number of animals and fish that live at different
ocean depths. Most of the different species of animals and fish depend on simple plants for their food.
These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon
dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe.
How important seawater is!
     Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in
large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains
are delicately balanced.
     The bad news about the food chains in the oceans is that they are under threat because of man. People
once thought that the oceans were so big that it didn't matter if we dumped rubbish into them or caught
huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans
have started to drop.
    Thankfully, the world is taking steps to protect the future of our oceans by introducing international
agreements to protect marine habitats (海域). Most countries have introduced fishing restrictions (限制)
to protect fish stocks in the oceans and new techniques are being pioneered to deal with pollution. Finally,
the importance of protecting oceans is being made known to more people. This is just the beginning of a
long process to protect the oceans for our future. We depend on the oceans for fish which are an important
part of the human diet. How important seawater is!

1. Which of the following is the proper order of the food chain?

A. small animals→algae→microscopic animals→large animals man
B. algae→microscopic animals→large animals→larger animals→man
C. small animals→algae→large animals→microscopic animals→man
D. microscopic animals→algae→large animals→larger animals→man

2. People used to think that the rubbish thrown into the sea ____.

A. wouldn't harm the fish in the sea
B. would change the balance of the food chain
C. would be broken down in the sea
D. wouldn't do much harm to the sea

3. From the passage, we learn that ____.

A. most fish and sea animals live at the surface of the seas
B. it is very difficult to break the balance of a food chain
C. too much fishing has caused the decrease in fish stocks
D. it won't be long before the problems concerning oceans will be solved

4. Which of the following is NOT a way being used to protect oceans?

A. The use of international agreements.
B. Forbidding fishing to protect fish stocks.
C. The use of new techniques.
D. Raising people's awareness of the need to protect oceans.

5. What would be the best title of the passage?

A. The importance of seawater.
B. Life in the oceans.
C. How to protect food chains.
D. How to deal with seawater pollution.

     The world itself is becoming much smaller by using modern traffic and modern communication means.
Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the
biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We
see it, smell it, drink it and even hear it.
     Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem
was not so serious because there were not so many people. When the land was used up or the river was
dirty in one place, man moved to another place. But this is no longer true.
     Man is now slowly polluting the whole world.
     Air pollution is still the most serious. It's bad for all living things in the world, but it is not the only one
kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us
angry more easily.
     Many countries are making rules to fight pollution. They stop people from burning coal in houses and
factories in the city, and from putting dirty smoke into the air. Pollution by SO₂ is now the most dangerous
kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there
will be less air pollution.
     The earth is our home. We must take care of it. That means keeping the land, water and air clean. And
we must take care of the rise in pollution at the same time.

1. _____, our world is becoming much smaller.

A. Because of the rise in pollution
B. Thanks to science development
C. Because the earth is being polluted day and night
D. Because the earth is blown away by the wind every year

2. Hundreds of years ago, life was _____ it is today.

A. much easier than
B. as easy as
C. much harder than
D. as hard as

3. Pollution comes in many ways. We can even hear it. Here "it" means _____.

A. rubbish (垃圾)
B. noise pollution
C. air pollution
D. water pollution

4. Air pollution is the most serious kind of pollution because _____.

A. it makes much noise
B. it makes us angry more easily
C. it makes our rivers and lakes dirty
D. it's bad for all living things in the world

5. Which of the following is NOT true?

A. Many countries are making rules to fight pollution.
B. The pollution of the earth grows as fast as the world population does.
C. The problem of pollution is not so serious because there are not so many people living on the earth.
D. If people could go to work by bus or bike instead of car or motorbike, it would be helpful in fighting
    against the problem of SO₂.

     Qiao is a sixth grader at Yuhui Primary School. He is only 12 years old but has been smoking for three
years. Liu, 15, is a Junior 2 student at Chicheng No. 2 Middle School. He began smoking four years ago.
"Smoking is part of my life," Liu said. Qiao and Liu are not those boys' real names. But their problem, smoking,
is a very real problem. In many countries, smoking is becoming a bigger problem for young people. Most
smokers start in their teens (years of a person's age from 13 to 19) or earlier.
     A study of 8,000 Beijing students last May told us that smoking is a problem for many Chinese kids.
More than 21% of middle school students and 6% of primary school pupils said they smoked.
     "If young people start smoking early, they will probably get addicted to nicotine. And it will be very hard
to give up later on," said a professor.
     Every year, about four million people die because of smoking. And if people keep smoking, that number
will go up to about 10 million a year by 2030, the World Health Organization (WHO) says. So we have to
learn and tell others about the dangers of smoking.

1. The sentence "Smoking is part of my life." probably means "_____". 

A. I don't smoke very often.
B. Smoking is very important to me.
C. I don't smoke at all.

5. As middle school students, what should we do from now on?

A. We should start smoking after middle school.
B. We should ask others to smoke outside.
C. We should laugh at smokers.
D. We should say no to smoking.

     It's 5:00 in the morning when the alarm (闹钟) rings in my ears. I roll out of bed and walk blindly through
the dark into the bathroom. I turn on the light and put on my glasses. The house is still as I walk downstairs
while my husband and three kids sleep peacefully. Usually I go for a long run, but today I choose my favorite
exercise DVD, Insanity. Sweat pours down my face and into my eyes. My heart races as I face my body to
finish each movement. As I near the end of the exercise, I feel extremely tired, but a smile is of my face. It's
a smile because the DVD is over, but a smile of success from pushing my body to its extreme limit.
     Some people enjoy shopping, smoking, food, work, or even chocolate. But I need exercise to get through
each day. Some shake heads when they see me run through the town. Others get hurt when I refuse to try just
one bite of their grandmother's chocolate cake. They raise their eyebrows, surprised by my "no thank you," or
by my choice to have a salad. Over the years, I have learned it's okay to just say "no." I shouldn't feel sorry for
refusing food that I don't want to eat.
     So what drives me to roll out of bed at 5:00 a.m.? What gives me the reason to just say to ice cream?
Commitment. A commitment to change my life with a way that reduces daily anxiety, increases self-confidence
and energy, extends life and above all improves my body shape. This is the point where a smile appears on my
face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right. It's through
commitment and sweat that I can make a difference within myself inside and out.

1. Why is there a smile on the author's face in the morning?

D. She has difficulty getting along with others.

     Getting rid of dirt, in the opinion of most people, is a good thing. However, there is nothing fixed about
attitudes to dirt.
     In the early 16th century, people thought that dirt on the skin was a means to block out disease, as medical
opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger
was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So
did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt
in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a
bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
     Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor
ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply
and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have
moved beyond science since World War Ⅱ. Advertisements repeatedly sell the idea; clothes need to be whiter
than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
     Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children
off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an
American immunologist (免疫学家), encourages children to play in the dirt to build up a strong immune
system. And the latter position is gaining some ground.
