Water can change from a solid to a liquid or to a gas easily. This is why we always have fresh water. Now let us find out how it does. The heat of the sun turns liquid water into gas from the oceans, seas, rivers and lakes. The heat also turns liquid water into gas from the ground, the plants and the animals. Water in the gas rises and turns into clouds in the air.
When the clouds come near a mountain, they rise high. As the clouds rise, they get cooler. The higher they rise, the cooler they become. Then more and more water gas turn into water drops. In this way, the drops of water in the clouds get bigger and bigger. Then they fall to the earth as rain.

The little cars will cost much less to own and to drive. Driving will be safer，too，as these little cars can go only 65 kilometers an hour. The cars of the future will be fine for getting around a city，but they will not be useful for long trips. Little cars will go 450 kilometers before needing to stop for more gas(汽油).
If big cars are still used along with the small ones，two sets of roads will be needed in the future. Some roads will be used for the big，quick cars and other roads will be needed for the slower，smaller ones.

Look at the center circles of Diagram (图) A and Diagram B. Which of the centre circles looks larger?
Take a first look and you probably think that the centre circle in Diagram A is smaller than that in Diagram B. In fact , they are exactly the same size.
Then look at the picture on the right. What do you see? A vase ? Or two faces? Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can never see them at the same time.
"What"s happening? Is something wrong with my eyes?" You may wonder at what you see. Don"t worry. Here is how it goes:
When we look at things, our eyes send messages to our brains and then our brains interpret (解读) the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it "Visual illusion" (视觉错误).
Movie makers often make use of illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey I shrunk the kids just make use of illusions.
小题1:The centre circle in Diagram A looks smaller than that in Diagram B. That"s because .
A. something is wrong with our eyes
B. the two circles are not the same size
C. our brains interpret the information in a wrong way
D. the two pictures change quickly from one to the other

There are four basic blood groups: A, B, AB and O. A single test can tell us a person’s blood group. Everybody is born with one of these four blood groups. People’s blood group, like hair colour, is inherited (继承) from parents.
Because the substances contained in each group are different, transfusion must be given carefully. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can be given to any other group, so it is often called the universal donor. On the contrary, AB is sometimes called the universal recipient (接受者). However, before being given the transfusion, patients usually receive only salt or plasma (血浆) until their blood can be matched as exactly as possible. In this way, it is possible to avoid any bad results of the transfusion.
There is a relationship between our blood groups and our nationalities. Among the Europeans, about 42 percent are blood group A while 45 percent are blood group O. The rarest is blood group AB. However, some American Indian groups are nearly 100 percent blood group O.
小题1:Which of the following shows the correct relationship in blood transfusion? (→ =" giving" blood to)
小题2:Usually, before being given a transfusion, ________.
| A．a person needs to receive salt or plasma first |
| B．a person needs to have a good rest |
| C．a person needs to have a lot of food and water |
| D．a person needs to find the person with the same blood group as him |
| A．A | B．B | C．AB | D．O |
A. A person’s blood group depends on his parents.
B. There is only one kind of blood group in a person’s body.
C. About 13 percent of the Europeans have blood group AB.
D. Most of American Indians can be universal blood donors.
小题5:Which is the best title for the passage?
| A．Blood transfusion | B．Blood groups |
| C．Car accidents | D．Blood group and nationalities |
