Different from popular thoughts, colds are not caused by bad weather. Colds are caused by viruses
(病毒) in the body, and you are better out on the snowy day than you are in a warm room, with your
friends, who just may be passing the virus around. If you feel a chill (寒冷) when you are coming down
with a cold, you are already sick. A chill is an early sign of the cold.
The virus can spread through air when a cold-sufferer (感冒患者) coughs or sneezes. Surprisingly,
this is not the most usual way of spreading, Many studies have now shown that most colds are "caught"
by hands. A cold-sufferer rubs her nose, so spreading the virus to her hand. Then a friend comes to visit
her. They shake their hands. The friend then gets something to eat by hand, and several days later she
catches a cold. Although some parents pick up their children"s tissues (纸巾) and carefully throw them
away, they fail to wash their hands. They"ll catch the colds, too.
Cold viruses can also be spread by objects, for example, telephones, plates. The cold-sufferer as well
as other members of the house, by washing their hands often, will stop the viruses from spreading in a way. |

Have you ever seen the film Traveling Bird? In the film, groups of birds fly high above the sky and cross
the way above snow, rivers, fields, sea and grassland. I"m sure you will love the beautiful picture when you
see the film.
But you may not feel so good if you have learnt about bird flu (禽流感) from TV or on the Internet. Some
governments had to kill chickens in their cities. A large number of chickens and even some people died in Asia,
and nearly 8,500birds died in Russia because of bird flu.
Chickens can get bird flu from the feces (粪便) of the passing birds. It is not so difficult to control the
chicken in cages or on farms. But it is much more difficult to control the birds in the sky.
Luckily, scientists have found a medicine for bird flu. But the virus (病毒) can change easily and quickly.
So bird flu is still a serious problem we must face. |
根据短文内容，判断下列句子的正误，正确的用“T”，错误的用“F” 。
( )1. We know how birds get bird flu from the film Traveling Bird.
( )2. Not only birds and chickens but also man can get bird flu.
( )3. The feces of the passing birds can not cause bird flu.
( )4. It is easier to control chickens than to control flying birds.
( )5. Scientists have found the medicine, so we needn"t worry about bird flu any more. |

Since the earliest times, trees have always been very useful and important to man who made use of
them in many ways. Even today trees continue to serve man in many ways. Trees provide man with
fruits and building materials in the form of wood. Without trees it would be impossible to build houses,
boats and even bridges. Furniture such as tables, chairs and beds is made of wood.
In the tropics (热带地区) where it is very hot all through the year, trees protect man from the terrible
heat. They are also useful.in preventing good and rich top soil from being washed away during heavy
rains which are so common in the tropics. If there were no trees or vegetation (植被) of some kinds to
hold back the soil with their roots, heavy rains would wash away the rich surface soil that is so important
and necessary to agriculture. The result is that the land becomes a desert.
There are so many desert areas in the world. A long time ago these desert areas must have been very
rich fertile (肥沃的) areas, but since our ancestors (祖先) in the distant past had no enough knowledge
about science of nature, they cut down all the trees in the areas where they lived and never planted new
ones. By and by, the rich surface soil was blown away and washed away by strong wind and heavy rain.
In the end the land was turned into useless deserts where nothing could grow. |
| 1. Trees provide ______ in the form of wood |
| [ ] |
A. man with houses
B. man with fruits and building materials
C. people with bridges
D. people with boats |
| 2. ______ are made of wood. |

and that people should not be forced to go on living when conditions of life have become unbearable. They
say that people should be allowed to die with dignity (尊严) and to decide when they want to die. Others
don"t agree and say that life under any conditions is better than death and that the duty of doctors is always
to extend life as long as possible. And so the battle goes on and on without a definite (明确的) answer. |

It was reported that over 300 million people in China were suffering from short-sightedness
(近视眼).
As more children suffer from eye trouble, their parents hope to cure the disease with medicine
equipment by correcting the way children eat and sit. But in fact the cure given to one"s eyes should
start with the exercise on one"s feet. Three methods to protect eyes are as follows.
Firstly, don"t fasten your shoes too tightly. Try wearing loose socks or walking bare-footed (赤脚)
at home. When traveling, try wearing cloth shoes.
Secondly, walking on tiptoes (踮着脚) can help improve one"s eyesight and prevent short-sightedness.
It"s said that few ballet performers are short-sighted.
Thirdly, rope skipping is good for one"s eyesight. When skipping, one has to react quickly, which
excites the brain as well as the eyes. It may also help make one grow taller.
Besides foot exercise, it is good to pull one"s ears. Pulling the ear 20 times is a good way to reduce
the pressure on one"s eyes. |
| 1. What"s the best way to protect one"s eyes? |
| [ ] |
A. Curing the disease with medicine.
B. Using the equipment to correct the way children read and sit.
C. Starting with the exercise on one"s feet.
D. Taking showers very often. |
| 2. The undeline word "tightly" means ______ in Chinese. |
| [ ] |
