still. On the far side of the water is some farmland and further away, across the field, is an old church built
on a hill. It has just stopped raining. The brook (小溪) flowing into the lake is full and there is still some
half-melted (半融化的)snow from last winter on the ground.
The reason why the water is so clear, and everything is so quiet and still, is that most of the plant and
animal life in and around the lake is dead. There are no birds because all the fish and insects, which the
birds need for food, have disappeared. Many trees in the forest are losing their leaves and bark (树皮), and
are sick and dying. Others were blown down by the high winds of last winter, A farmer is working in a field
planting something, but unless he plants a stronger kind of seed this year. the crop will be between 25 to 40
percent lower than a few years ago. The stones of the old church tower are turning to powder and unless
the tower is repaired soon, it will fall down.
All the death and destruction in this place is caused by the smoke coming out of factories and poisonous
gases from cars and trucks. And yet this silent lake is hundreds of kilometers away from the nearest factory
and highway.

Many guests like the idea because they don"t have to bring their own. But, if you travel to Beijing,
remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests
with these disposables. They want to ask people to use less disposable things. Many disposable things are
made of plastic, not easy to rot away. People throw them away after using them only once. It is a waste of
natural resources and is very bad for the environment. Do you know, one Chinese person makes as much as
400kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away
about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take between
100 and 400 years to break down. So the less plastic we throw out, the better. So, wherever you travel, bring
your own things and use them again and again.
At home and school, you can also do something to make our world a better place. Try to use daily
necessities (日用品) once more. Use cloth shopping bags, not plastic ones. After using a plastic bag, wash it
out and let it dry. Then you can use it over and over again. Do not use paper cups. At your school canteen,
use your own bowl and chopsticks instead of disposable ones.

When you haven"t got it, you think about it all the time. Our biggest enemies are not terrible diseases. We
are our own biggest enemies because we sometimes destroy our own good health. Some of us eat too
much, drink too much and smoke too much. And though our reason tells us we should control ourselves,
we find it difficult. The fact is that most human beings need stimulation.(刺激) Who doesn"t enjoy a drink
after a busy day? Only a smoker knows the pleasure of a cigarette with a cup of coffee.
The danger is when these innocent pleasures run our lives and so destroy our health. When you find
yourself eating between meals or eating too much rich food, when you can only keep yourself going by
taking frequent drinks or by smoking one cigarette after another, then it"s time to stop and think what you
might be doing to yourself. The funny thing is that when we don"t control ourselves, simple pleasures are
no longer simple pleasures.
All right, I know what you"re thinking. You"re probably saying: "It"s all very well for him to talk, but I
can"t help myself. I need that extra bit of food, that extra drink, that extra cigarette. Life has so many
pressures that I can"t manage without them." But I"m saying you can help yourself. Not only that you must
help yourself. Because if you don"t help yourself, no one else can. So be your own best friend.

of chocolate you know that these are things you can eat. You can also use other senses when you choose
your food. You may like it because it smells good or because it tastes good. You may dislike some types of
food because they do not look, smell or taste very nice. Different animals use different senses to find and
choose their food. A few animals depend on only one of their senses, while most animals use more than one
sense.
Although there are many different types of food, some animals spend their lives eating only one type. The
giant panda (大熊猫) eats only one particular type of bamboo (竹子). Other animals eat only one type of food
even when given the choice. A kind of white butterfly (蝴蝶) will stay on the leaves of a cabbage, even though
there are plenty of other vegetables in the garden. However, most animals have a more varied diet (多样化饮
食). The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will
be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In
countries such as France and Britain, people eat foods with too much sugar. This makes them overweight,
which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad
for the health. Choosing the right food, therefore, has become an area of study in modern life.
B. are not satisfied with their food
C. choose food in similar ways
D. eat entirely different food
B. the food color changes
C. they move to different places
D. they are attracted by different smells

Ali is from a Middle Eastern country. He now stays in the USA. He smokes a lot of cigarettes (香烟) every
day. He has smoked for nine years. Ali says," I tried to quit (放弃) smoking in my hometown, but it was
impossible. My brothers smoke. All my friends smoke. At parties and at meetings, almost all the men smoke.
Here in the United States, not as many people smoke. It will be easier to change my habit here."
Many smokers are like Ali: they want to stop smoking. The smokers know that smoking is bad for their
health. They know it can cause cancer and heart disease. But it is difficult for them to give up smoking because cigarettes have a drug in them. The drug is nicotine (尼古丁). People who smoke a lot need nicotine.
When a person first begins to smoke, he usually feels terrible. The nicotine makes him sick. In a few days,
the smoker"s body is used to the nicotine, and he feels fine. Later, the smoker needs nicotine to keep feeling fine. Without nicotine, he feels bad.
It is very hard to quit smoking, and many people who quit will soon smoke again. At a party or at work they will decide to smoke "just one" cigarette. Then they will smoke another cigarette, and another. Soon they become smokers again. Maybe there is only one easy way to quit smoking: never start.

asthm a(哮喘)attacks. A recent attack happened on October 2, after he pushed himself too hard in physica
l exercise. Running, power walking, jogging and push-ups took their toll. When Jeremy got home an hour
or two later, he was out of breath. He needed to use a nebulizer (喷雾器), a machine that helps send
medicine quickly to the lungs, to get his breathing back to normal.
Asthma attacks like Jeremy increase in September and October. More than six times as many asthma
sufferers who are primary-school age need hospital treatment in the fall as in the summer.

start passing viruses around. A viral infection (感染) can cause an asthma attack. There are also certain fall
allergies (过敏症) that can cause attacks. Exercise is another common cause of an attack. Besides, the stress
of school can make asthma worse.
Parents can play a big role in helping kids with asthma start the school year right. Dawne Gee"s
10-year-old son, Alexander, has had asthma since he was a baby. Before the school year starts, she tells
school workers in writing about her son"s asthma.
The Gees live in Kentucky, which has passed laws allowing students to carry their asthma medication
(药物治疗)with them at school. Alexander"s mom makes sure he has his inhaler (人工呼吸器) with him
when he goes to school and that he keeps it on hand at all times. In Delaware, where Jeremy lives, kids are
allowed to carry their inhalers at school.
The American Lung Association says that about 6.2 million American children suffer from asthma.
