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. |

The world itself is becoming much smaller by using modern traffic and TV, telephone and so on. Life today is much easier than it was hundreds of years ago, but it has also brought new problems. One of the biggest is pollution. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. Man is now slowly polluting the whole world..
Air pollution is still the most serious. It’s bad to all living things in the world. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us become angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city.
The pollution of SO2 is now the most dangerous problem of air pollution. It is caused by heavy traffic. It is sure that if there are fewer people driving, there will be less air pollution.

Water can be a liquid, a solid or a gas. When it is a solid, it can be as hard as stone. When it is a liquid, it can run through your fingers. When it is a gas, you may not see or feel it.
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.

When you watch TV and play video games you make global(全球的) warming worse! It may seem hard to believe, but when electricity is made, so are greenhouse gases(溫室氣體). This means that every time you use electricity you help make global warming worse!
Cars are also making global warming worse. They burn fossil fuels(化石燃料) in their engines, and send lots of greenhouse gases into the air.
Global warming may be a big problem, but we can all help stop it. People can try to drive their cars less. Or even get ones that run on sunlight! You can also help. Let’s try one of these top ideas:
(1) Try to use less electricity. Turn off lights, your television, and your computer when you’ve stopped using them. To make electricity, fossil fuels are burned in big factories. But burning fossil fuels also makes greenhouse gases. You should also try to watch less TV.
(2) Plant trees. Not only is it a fun thing to do, but it is also a great way to lower the number of greenhouse gases in the air. Trees take carbon dioxide out of the air when they grow.
(3) Don’t throw away your rubbish, try to recycle it. If rubbish is not recycled, it is put in the ground. There it rots(腐爛) and makes a greenhouse gas called methane(甲烷).So try to recycle cans, bottles, plastic bags and newspapers. It’ll make you feel great! And it’ll help the Earth.
【小題1】If we _____, we may make global warming worse.
| A．use less electricity | B．drive a car on sunlight |
| C．plant trees | D．throw away rubbish |
| A．turning off lights | B．shutting down computers |
| C．turning up CD players | D．turning off TV |
| A．Methane | B．Cans | C．Newspapers | D．Bottles |
| A．the less electricity is used, the more greenhouse gases are produced |
| B．the more electricity is used, the more greenhouse gases are produced |
| C．more electricity is used, less greenhouse gases are produced |
| D．less electricity is used, more greenhouse gases are produced |
| A．Driving cars on sunlight helps to stop global warming. |
| B．When cars burn fossil fuels, they produce greenhouse gases. |
| C．When trees grow, they send carbon dioxide into the air. |
| D．By planting more trees, we can lower the number of greenhouse gases in the air. |

Taking away a city’s rubbish is a big job. Every day trucks come into a city to collect it. Most rubbish is made up of things we can’t eat or use. If we kept these things we would soon have a mountain of rubbish.
In some cities the rubbish is collected and taken outside of the city to a dump(垃圾站). Often the city dump is placed where the ground is low or there is a big hole. The kitchen rubbish is broken into small pieces and sent into the sewage system. The sewage system takes away the used water from toilets, bathtubs(澡盆) and other places.
To keep mice and flies away, some earth is used to cover the newly dumped rubbish. Later, grass may be planted on the rubbish-filled land. Finally, a house or a school may be built there, and then you’d never know that this had once been an old rubbish dump.
In other cities the rubbish is burnt in special places. The fire burns everything but the metal. Sometimes the metal can be used again in factories where things are made of metal. The food parts of rubbish are put in special piles where they slowly change into something called humus(腐殖土), which looks like black earth. It is rich with kinds of things that feed plants and help make them grow.
【小題1】You can most probably read the passage in _______.
| A．a(chǎn) history book | B．a(chǎn) TV guide |
| C．a(chǎn) science book | D．a(chǎn) telephone book |
| A．排污 | B．染色 | C．洗滌 | D．吸塵 |
| A．By burning it off. | B．By putting it in water. |
| C．By throwing it away. | D．By reusing and recycling it. |

In the 13th century, the Italian traveler, Marco polo , traveled a long way to China , During his stay in China , he saw many wonderful things . One of the things he discovered was that the Chinese used paper money . In western countries , people did not use paper money until the 15th century . However , people in China began to use paper money in the 7th century .
A Chinese man called CaiLun invented paper almost 2000 years ago. He made it from wood . He took the wood from trees and made it into paper . He then put these pieces of paper together and made them into a book .
Now paper still comes from trees . We use a lot of paper every day ! If we keep on wasting so much paper , there will not be any trees on the earth . If there are no trees , there will be no paper . Every day , people throw away about 2800 tons (噸) of paper in our city . It takes 17 trees to make one ton of paper . This means that we are cutting nearly 48000 trees every day . Since it takes more than 10 years for a tree to grow , we must start using less paper now . If we don’t , we will not have enough time to grow more trees to take the place of those we use for paper .
So how can we save paper ? We can use both sides of every piece of paper , especially when we are making notes .We can choose drinks in bottles instead of those in paper packets . We can also use cotton handkerchiefs (手帕) and not paper ones . When we go shopping , we can use fewer paper bags . If the shop assistant does give us a paper bag, we can save it and reuse it later .
Everyone can help to save paper . If we all think carefully , we can help protect trees . But we should do it now , before it is too late .
【小題1】When he was in China , Marco polo ___________ .
| A．discovered CaiLun invented paper |

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）.
【小題1】Satellites travel _____________.
| A．in space | B．in the atmosphere | C．a(chǎn)bove the ground | D．a(chǎn)bove space |
| A．the weather satellites can do it easily | B．clouds form in the atmosphere there |
| C．the weather forms in the atmosphere | D．the pictures can forecast the weather |
| A．when they have received satellite pictures |
| B．a(chǎn)fter comparing the pictures with earlier ones |
| C．before they received satellite pictures |
| D．while they study satellite pictures |
| A．taking pictures of the atmosphere | B．receiving pictures of the atmosphere |
| C．doing other work in many ways | D．weather forecasting to the pictures |

Do you like traveling? How can you make your trip interesting? Here’s some advice.
Read!
Before you leave, you should find some information about the place, such as its geography, history and people. You can introduce that place better by reading.
Take photos!
If you want to take some photos, remember to choose the most special sights. Don’t choose the sight you can see in other places. For example, Qingdao and Ningbo are coastal cities, so don’t only take photos of the sea. You should take photos of something else, too.
Taste!
You’d better taste some specials(特產(chǎn)) in the area. Food in some places is very delicious. So why not taste it? Maybe you have just one chance to taste it in your life.
Write!
When you visit a place, you should take a pen and a notebook, so you can write down what you see and what you think during the trip.
