Healthy eating habit along with regular exercise is the only way to become fit. If you have the correct
number of calories and exercise regularly, you will lose weight, keep fit, and feel great, too.
During your teenage years, it is important to give your body the energy it needs. If you skip (跳过) meals,
you won"t get enough calories, and then you will feel tired. By the way, calorie is just another word for energy.
About 50% of your calories should come from rice, bread, vegetables and fruit. You also need to drink a lot of
water, 6 to 8 glasses a day. Water helps keep your system clean. Drinking enough water will make your skin
better and make you healthy.
Exercise is something that can help to make you look good, feel good and be healthy. Experts suggest that
teenagers spend at least 30 minutes exercising, five times a week. That is easy to do! You can walk or ride
your bike to school, and do sports at school. However, teenagers often give up sports, saying they have no
time left after their studies. In fact, doing exercise can help them sleep better at night and increase their ability
to focus on their study.

because they"re new. We want to take care of the environment, we don"t want to pollute the air and we
don"t want to waste energy and resources. But we also want to be fashiona-ble. How can we buy fashionable
clothes and protect the environment?
Old styles are fashionable again, so one way is to buy second-hand clothes - recycled clothes. Another
way is to buy fair trade clothes. These clothes are either recycled or made in a way that protects the
environment. They also protect the people who make the clothes.
Surprisingly, white cotton is one of the least environmentally-friendly crops of all. To protect the cotton,
the growers use chemicals that pollute water, make farm workers ill and kill wildlife. New materials, such as
hemp and bamboo, grow quickly and are more environmentally-friendly. These materials are very soft, and
look fantastic. The best materials are coloured using natural dyes, made from plants.
Environmentally-friendly clothes are practical but until now they were often dull. Now fashion-designers
are working with these materials and the clothes are beautiful as well. So now we can buy fashionable clothes
that are also environmentally-friendly.

what you"ve been thinking about lately. When you leave, she gives you some medicine, but also a list of
thinking skills that you are supposed to practice daily. She says that the way you think is causing some of
your illness.
Doctors and other scientists who study the human mind and try to explain why people behave in the way
that they do, called psychologists, are starting to believe it. You know that your brain is connected to every
part of your body through your nervous system (神经系统). Now scientists have proved that how you think
and feel can havean influence on the health of your body.
Stress (压力 ,紧张) is caused whenever there is a problem or a change in your life. Of course, everybody
has stress more or less; nobody"s life is perfect. In fact, stress is necessary. Without stress, wa would never
leam anything or grow or change. We would probably be bored"to death. But too much stress can hurt you. It
can weaken your body"s protection so that you are more likely to catch diseases. It can evenmake you more
likely to have an accident.
When you feel stress, your brain sends a message to your body to produce achemical called adrenaline (肾上腺素). Adrenaline speeds up your breathing and your heartbeat. Today you have a different kind of stress.
Problems like endless homework or troubles with your family are the kind of things you can"t fight or run away
from, so you don"t use up all that adrenaline. It just stays bottled up inside you, and that"s what can do
something bad to you.
What can you do about stress? First, you can try to find ways to change things so you aren"t under so
much stress. You can set up a plan to finish homework or go to a doctor or a psychologist to try to work
things out with your family or your friends. But sometimes you can"t change a stressful situation. Sometimes
you don"t even want to. A big change might be a good change, but it will still be stressful.
The link (关联) between your body and brain works in two ways. Your body can help your mind deal
with stress. If you are under stress, you need to take especially good care of your body. It"s important to get
enough sleep and eat nutritious meals. Some people take a vitamin-mineral pill every day. Another thing that
you can do is daily exercise. If you go walking or do aerobic dancing or work out at the gym, you give your
body a chance to burn up some of that adrenaline. Of course, a person who isn"t used to much physical
activity should start slowly. Anyone with a continuing physical problem should check with a doctor before
starting any exercise programs.
B. thoughts and behaviour
C. mind and nervous system
D. physical activity and daily exercise
B. One can do his homework to bum up adrenaline.
C. Diseases and accidents are caused by stress.
D. Everyone needs stress to improve himself.
B. it"s not stressful when a good change takes place
C. a big change will cause another stressful situation
D. a stressful situation can"t be changed without any effort
B. The Causes of Stress
C. The Advice on Health
D. The Nervous System
One cool April 22 mornig, people started the day as usual. Yet it was not a normal day. What"s so special
about April 22? The answer is simple. It is Earth Day People all over the world celebrate this important day.
The idea of having a special day to celebrate Earth began in the 1960s. Life was very different then. Few
people talked or even thought ahout the environment. Most people had no idea how dirty our air and water
were.
On April 22, 1970, twenty million (百万) Americans joined the first Earth Day activities. They showed
that people really did want to do something about the environment. Since then laws have been passed to
protect the air, water, land, and animals.
The vehicles such as cars and buses you ride in must pass tests to make sure they don"t cause too much
pollution. Thanks to this law, cars today release (排放) about half as many bad chemicals as cars did back
in 1970. As a result, the air we breathe is cleaner than it once was.
Rivers and lakes are also cleaner today than they were in the 1970s. It"s a good thing because they needed
a lot of help. The Cuyahoga River in Ohio was so polluted that rubbish and oil on the river even caught fire!
Today, the river is cleaner. It no longer burns. It"s healthy enough for birds, fish, and other animals.
Now the celebration has spread to other countries. More than 175 countries take part each year.
In 2007, people in China paid much attention to a big problem. People were throwing away 27 million
plastic bags a day ! People had "Bye-Bye Throwaway CultureWeek." They wanted everyone to see how
polluted it was to throw away so many plastic bags. In 2008, China passed new laws against them.
Every April 22, millions get together to clean and protect Earth. They also celebrate how far we have
come. Our job is to put this knowledge to work. You can help keep our planet healthy too!

Jogging is basically running at a steady (稳定的) speed over short or long distances. It became popular
some twenty years ago and has remained a favorite way of keeping fit for lots of people.
One of the main advantages of jogging over many other sports is that it can be done anywhere. People jog
in parks, in the country side and even in urban areas. No special equipment is required no costly hats, or balls,
and no expensive sports kit. Good quality running shoes are advisable. Special jogging suits are widely available
these days and can be bought quite cheaply but are not necessary. In addition to being able to jog anywhere,
you can also jog at any time, in any season! It"s not unusual to see joggers exercising in the height of summer
or in the depth of winter!
The act of jogging doesn"t require any special training or skill. You do need to be basically healthy and then,
after a few basic warm-up bends and stretches, you are ready to begin. You simply start running, gently, and
then build up to a steady speed. Do not overtire yourself by trying to go too fast. It is best for you to run at
a steady and comfortable speed.
Jogging is a single sport. You don"t need to wait until you have gathered a team or found a partner. You
can jog alone. A few words of warning however: lone women joggers should be especially careful when
choosing jogging routes, particularly at night time.
Jogging is excellent for keeping fit. It"s good for the lungs, the heart and the circulation. It"s easy and
it"s convenient. Why don"t you try it? If you require more information, talk to one of the instructors at the
sports centre. We are only too happy to help. Please remember: if you do decide to jog, talk to your doctor
first if you have any health worries. Happy jogging!

colds are caused by cold weather. They are not. They are caused by viruses (病毒) passing on from person
to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has
one.
If cold weather causes colds, it would be reasonable to expect the Eskimos to suffer from them forever.
But they do not. And in isolated Arctic regions explorers (探险者) have reported being free from colds until
coming into contact again with the outside world by way of packages and mails dropped from airplanes.
During the First World War soldiers who spent long periods in the trenches, cold and wet, showed no
increased tendency to catch colds. In the Second World War prisoners at the notorious Auschwitz
concentration camp, naked and starving, were extremely surprised to find that they seldom had colds.
At the Common Cold Research Unit in England, volunteers took part in the experiments in which they
gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths,
they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in
drafty rooms. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not
one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If, then, cold and wet have nothing to do with catching colds, why are they more frequent (often) in the
winter? Despite the most painstaking research, no one has yet found the answer. One explanation offered by
scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes
it easier for cold viruses to be passed on.
No one has yet found a cure for colds. There are drugs and pain suppressors such as aspirin, but all they
do is to relieve the symptoms (症状).
