All living things on the earth need other living things to live. Nothing lives alone. Most animals must
live in a group, and even a plant grows close together with others of the same kind. Sometimes one
living thing kills another, one eats and the other is eaten. Each kind of life eats another kind of life in
order to live, and together they form a food chain (链条). Some food chains are simple, while others
are not. But all food chains begin with the sun, and all food chains become broken up if one of the links
disappears.
All life needs sunlight to live on. But only plants can use sunlight directly. Plants are "factories". They
make food from sunlight, water and things in the soil and air. Plants feed all other living things. Animals
can only use the sun"s energy after it has been changed into food by plants. Some animals feed directly
on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly.
What about human beings? We are members of many food chains. We eat rice, vegetables, and fruits
and so on. We also eat meat and drink milk. But men often break up the food chains. They kill wild
animals. They also make rivers, lakes and seas polluted, when these rivers, lakes and seas are polluted,
the fish in them can not be eaten. If men eat the fish, they will get strange diseases.
Each form of life is linked to all others. Breaking the links puts all life in danger.

If you do not use your arms or your legs for some time, they will become weak, when you start using
them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to
know that memory works in the same way. When someone says that he has a good memory, he really
means that he keeps his memory in practice by using it. When someone else says that his memory is poor,
he really means that he does not give it enough chance to become strong.
If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that
he has a poor memory, many of us think that his parents may be blamed, and few of us know that it is just
his own fault (过错). Have you ever found that some people can"t read or write but usually they have better
memories? This is because they cannot write them down in a small notebook. They have to remember days,
names, songs and stories, so their memory is the whole time being exercised.
So if you want to have a good memory, practice remembering things in a way as other people do. | | 1. Someone can"t have a good memory if ______. | [ ] | A. he can"t read or write

world, and there are more than 2,500 kinds of them.
No one likes the mosquito. But the mosquito may decide that she loves you. She? Yes, she. It"s true
that male mosquito doesn"t bite (咬) and only the female mosquito bites because she needs blood to lay eggs.
She is always looking for things or people she wants to bite. If she likes what she finds, she bites. But if she
doesn"t like your blood, she will turn to someone else for more delicious blood. Next time a mosquito bites
you, just remember you are chosen. You"re different from the others!
If the mosquito likes you, she lands on your body without letting you know. She bites you so quickly and
quietly that you may not feel anything different. After she bites, you will have an itch (痒) on your body
because she puts something from her mouth together with your blood. By the time the itching begins, and she
has flown away.
And then what happens? Well, after her delicious dinner, the mosquito feels tired. She just wants to find a
place to have a good rest. There, on a leaf or a wall, she begins to lay eggs, hundreds of eggs. | | 1. "Mosquito" means _______ in Chinese. | | [ ] | A. 苍蝇

ill and may die. Blood is very important. People have always known that. At one time, some people even
drank blood to make them strong!
When doctors understand how blood goes around inside the body, they try ways of giving blood to
people who need it. They take blood from the healthy people and give it to people who need it. This is
called "blood transfusion" (输血). The blood goes from the arm of the healthy person into the arm of the
sick person.
But there are two problems. First, it does not always work. Sometimes people die when they have
blood transfusion. Later, doctors find that we do not all have the same kind of blood. There are four
groups---O, A, B and AB. We all have blood of one of these groups. They also find that they can give any
kind of blood to people of group AB. But they find that they must give A-group blood to A-group people
and B-group blood to B-group people. I have O-group blood and the doctor told me that I could give blood
to anyone else safely.
There is another problem. To give blood of the right kind, doctors have to find a person of the right
blood group. Often they can not find a person in time. If they have a way to keep the blood until someone
needs it, they can always have the right kind of blood. At first they find they can keep it in bottles for fifteen
to twenty days. They do this by making it very cold. Then they find how to keep it longer. In the end they
find a way of keeping blood for a very long time. We call a place where we keep money a "bank".
We call a place where we keep blood a "blood bank". One day, when you grow up, you may decide to
give blood to a "blood bank". In this way you may stop someone from dying. Or perhaps one day you may
become ill. You may need blood. The "blood bank" will give it to you. | 1. From the passage, we learn that sometimes people die when they have blood transfusions because

D. keep blood for more than twenty hundred years | | 4. From the last paragraph of the passage, we learn that _______. | | [ ] | A. the writer thinks it"s good to give blood to a "blood bank"
