Now satellites are helping to forecast the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere(大氣), because this is where the weather forms. They send these pictures to the weather stations. So meteorologists(氣象學(xué)家)can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.
So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead(提前).

Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries slowly.
You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
Your hands and wrists (手腕)
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something. 2) Keep your elbows (肘部) at the same height as the keyboard. 3) Stop something and exercise your hands, wrists and fingers in a different way.
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should all be in front of your eyes. Your forearms(前臂), wrists, hands and the upper(上部) part of your legs should all be parallel (平行) to the floor. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and necks.
Enjoy your computer, but use it safely.

Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.
The eye-recognition(眼睛識(shí)別) program is already being tested in shops and banks in the USA, Britain and France. Soon, this technology(技術(shù)) will change all other ways of finding out who people are.
However, scientists are working on other systems. Machines will soon be able to know you from the shape of your face or hands or even your smell! We already have machines that can tell who you are from your voice or the mark made by your fingers.
Eye-recognition is better than other kinds because your eyes don’t change as you get older, or get dirty like hands or fingers. And even twins have different eyes, so the program can be up to 94% correct, depending on(依靠) how good the technology is. Some programs may only be right 51% of the time. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eye-recognition.
In the future your computer will be looking at you in the eye. So smile!
【小題1】What is the advantage of using the eye-recognition program?
A.You needn’t use a machine. |
B.You needn’t remember a number. |
C.You needn’t look at the machine. |
D.You needn’t take some money with you. |
A.You type in your number. | B.You show your ID card. |
C.You look at the machine. | D.You say your name. |
A.Because eyes hardly change. |
B.Because hands or fingers can get dirty. |
C.Because people like the idea of the program. |
D.Because the program is widely used around the world. |
A.Remembering eyes. |
B.Remembering smells. |
C.Remembering fingerprints. |
D.Remembering the shape of faces. |

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering(不開(kāi)花的) plants.
Flowering plants can make seeds(種子). The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit.
Most non-flowering plants do not grow from seeds. They grow from spores(孢子). Spores are very, very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores fall on wet and shady(陰涼的) places, they usually grow into new plants.
【小題1】What fact does the passage lead you to believe?
A.Of all living things, animals are most important. |
B.Spores are seeds. |
C.All fruits of flowering plants have seeds. |
D.Without plants, man will die out. |
A.how plants can make food from air |
B.how spores grow into new plants |
C.why some plants have no seeds |
D.why non-flowering plants are more important than flowering plants |
A.a(chǎn) story book | B.a(chǎn) novel |
C.a(chǎn) science magazine | D.a(chǎn) laboratory report |

Should we be afraid of sharks? Maybe not. New research into the reasons for shark attacks (攻擊) suggests that sharks don’t like the way humans taste! In fact, most people who are attacked by the shark are still alive after receiving only one bite (咬). Why is this?
There are many opinions to explain why sharks sometimes attack people. One opinion is that sharks are just curious (好奇的). We know that sharks are the strongest animals in their environment, so they are not afraid of anything. Naturally, that means they are curious when they meet something unusual. Because they don’t have hands or feet., the only way they can find out an object is to bite it! It is thought that sharks sometimes bite humans for this reason, and then swim away.
Scientists also say that sharks would not waste energy trying to eat a human, as we have a lot of bones (骨頭). It is hard for a shark to eat us because sharks don’t have hands, and they can’t pull the meat off our bones. Maybe that’s why they only bite us once. Unluckily, one bite from a large shark is serious enough to hurt people greatly!
Another opinion is that sharks attack humans by mistake. Some sharks may sometimes mistake humans for a seal. An example of this is when a shark attack attacks a surfer. A surfer lying on a surfboard looks like a seal when seen from below. Sharks like seals because they have thick fat.
Whatever the reason for shark attacks on humans, sharks should be afraid of us. Sadly, we kill almost 40 million of them each year.
【小題1】What happens to people attacked by sharks?
A.Most of them because blind. | B.Most of them because of deaf. |
C.Most of them died. | D.Most of them are still alive. |
A.By biting. | B.By smelling. |
C.By touching. | D.By killing. |
A.Sharks pull meat off bones when they eat. |
B.Sharks might mistake humans for seals. |
C.Sharks like to attack surfers because of their thick fat. |
D.One bite from a shark is nothing serious. |
A.To tell surfers to stay away from sharks. |
B.To ask people to stop killing sharks. |
C.To let us know the reasons for shark attacks on people. |
D.To show that humans are much stronger than sharks. |

Long ago, people lived on wild animals, fruits and other plants and they didn’t need to use money.
As time passed, families had more products(產(chǎn)品) than they needed, such as animals and crops. So they needed to trade(交易) with others. They began to use money to make it easier. However, it was not like the money we use today. They used shells, rice, salt or large stones.
During the 600s BC, people began using coins as money. Because they were easier to carry than goods(貨物), countries began to make coins as their money.
The Chinese were the first to use paper money, probably in the 11th century. An Italian traveler, Marco Polo, saw the Chinese use paper money when he visited China in the 1200s. After his travel, he told the western people what he saw. But European countries didn’t start using paper money till the1600s.
Today we have many ways to pay for things, such as coins, paper money and cards. Some prefer to pay by card. That’s because paying with a card is easier and safer than carrying around a lot of “real” money.
【小題1】People began to use money because they ______.
A. lived on plants B. raised animals C. needed to trade
【小題2】People used ______ as money during the 600s BC.
