    The world itself is becoming much smaller by using modern traffic and modern communication. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution.
    To pollute means to make things unfit or unclean to use. Pollution comes in many ways. We see it, smell it, drink it and even eat it. Pollution is beginning to threaten (威胁) our health, our happiness and our life.
    Man has been polluting the earth from the time he first made fire, washed his clothes in the river and threw his waste on the ground. When land was used up or water became dirty, men moved on to another place. At first, the problem was not so serious because there was plenty of clean air, land and water. There weren't so many people then and their wants fewer. All the dirty things could be absorbed(吸收) by nature and soon covered over. But this is no longer true. The increase of pollution and the development of industry(工业) have changed that. Man is slowly poisoning(毒害)not only his environment but also himself.
    Through the use of poison, man has polluted the land, killing the animals. By putting dirty water and chemicals into rivers and lakes we have polluted our drinking water, killing the fish.
Our increasing population is part of the problem. More people, more waste.
     Where is this all to end? Are we turning the world into a big rubbish dump(堆存处)，or is there any hope that we can get rid of (摆脱，除去) the pollution? Luckily, millions of people have been warned of the danger of pollution. Large numbers of people are now working hard to bring pollution under control.
    The earth is our home. We must take care of it. This means keeping the land, air and water clean. And we must take care of the rise in pollution at the same time.

（1）、Which of the following is NOT true according to the passage?

A、We live on the earth, so we should look after it. B、Man is fighting against different kinds of pollution. C、To pollute means to make air, water and land unfit for use. D、All the waste produced by modern industry can be absorbed.

（2）、In Paragraph4, the underlined word “chemicals” mean ____________.

A、化学物质 B、医疗器械 C、污染源 D、塑料制品

（3）、Through the uncontrolled use of poison man has___________.

A、made the drinking water dirty B、polluted the land C、killed the animals D、all of the above

（4）、From the sentences “More people, more waste.” We know that ___________ .

A、we need more people, not more waste B、the increase of population caused more waste. C、there isn't any hope that we can get rid of the pollution D、More people have been warned of the danger of more waste.

（5）、Which of the following is TRUE according to the passage?

A、Man begins to understand the pollution. B、Man doesn't know how to control pollution. C、Man is doing something to control pollution. D、Man still doesn't realize how serious pollution is.

    Since the 1970s, scientists have been searching for ways to connect the brain with computers. Braincomputer interface(BCI) technology could help people with disabilities send commands to machines.
    Recently, two scientists, Jose Millan and Michele Tavella from the Federal Polytehnic School in Lausanne, Switzerland, show a small robotic wheelchair directed by a person's thoughts.
    In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
    “Our brain has billions of body cells(细胞). These send signals through the spinal cord(脊髓) to the body part to give us the ability to move. But spinal cord injuries(脊柱受伤) or other conditions can prevent these weak electrical signals from reaching the body part.” Tavella says. “Our system allows disabled people to communicate with outer world and also to control machines.”
    The scientists designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer finds meanings of the signals and commands the wheelchair with an engine. The wheelchair also has two cameras that tell objects in its path. They help the computer react to commands from the brain.
    Prof. Millan , the team leader, says scientists keep improving the computer software that finds meanings of brain signals and turns them into simple commands.” The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling objects. One example is this wheelchair.”
    He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can get advantages from. And the other is sure that they can use the technology for long.

Is there intelligent life on other planets? For years, scientists said "no" or "we don't know." But today this is changing. Seth Shostak and Alexandra Barnett are astronomers (天文学家). They believe intelligent life exists somewhere in the universe. They also think we will soon contact these beings．

Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time．Scientists believe the universe is about 12 billion years old．"This is long enough for other planets to have intelligent life， “say Shostak and Barnett．The second reason is size—the universe is huge．“Tools like the Hubble Telescope(哈勃望远镜)have shown that there age at least 100 billion galaxies，”says Shostak．“And our galaxy，the Milky Way，has at least 100 billion stars．Some planets going around these stars might be similar to Earth．”

In the past，it was hard to took for signs of intelligent life in the universe，But now. powerful telescopes(高倍望远镜)allow scientists to discover smaller planets—the size of Mars or Earth—in other solar systems．These planets might have intelligent life．

Have beings from space already visited Earth?“Probably not．”says Shostak．“It's a long way away．However，intelligent beings may contact us in other way，such as radio signals．In fact，they may be trying to communicate with us now，but we don't have the right tools to receive their messages．However，this is changin9．By 2025，we could make contact with other life forms in our universe and we might help each other．”

There is a lake near a forest in Sweden. The water in the lake is very clear and everything is quiet and still. On the far side of the water is some farmland and further away, across the field, is an old church built on a hill. It has just stopped raining. The brook(小溪) flowing into the lake is full and there is still some half-melted(半融化的) snow from last winter on the ground.

The reason the water is so clear, and everything is so quiet and still, is that most of the plant and animal life in and around the lake is dead. There are no birds because all the fish and insects, which the birds need for food, have disappeared. Many trees in the forest are losing their leaves and bark (树皮), and are sick and dying. Others were blown down by the high winds of last winter. A farmer is working in a field planting something, but unless he plants a stronger kind of seed this year, the crop will be between 25 to 40 percent lower than a few years ago. The stones of the old church tower are turning to powder and unless the tower is repaired soon, it will fall down.

All the death and destruction(破坏) in this place is caused by the smoke coming out of factories and poisonous gases from cars and trucks. And yet this silent lake is hundreds of meters aways from the nearest factory and highway.

The American Computer &. Robotics Museum was open to visitors in 1990 in Bozeman, Montana. At first it was planned to build in Princeton, New Jersey. The founders moved to Bozeman in 1988 and after looking at the area they decided to build the museum there. With Yellowstone National Park to the south and Glacier National Park to the northwest, the museum attracts thousands of visitors from all 50 states and over 50 countries. The American Computer &. Robotics Museum has been written about in many publications such as The New York Times, The New Yorker, Los Angeles Times, QST and USA Today.

When visitors first enter the museum, they are shown a video introducing the museum and its collections. All visitors are given the chance to join in tours led by friendly tour guides. We have had visitors aged from3 to 93- it is a big family. Over 1,000 exhibitions are shown in the 6, 000-squaremetre museum. Travelling through our museum, you will see the exciting 20,000 years of history of the information age. Technology becomes easier to accept when one learns about its origins(起源) in the natural process(进程) of human development.

We all know that many women like to wear dresses. They enjoy many kinds of colourful and popular dresses. But have you ever heard of a 4D dress?

Jessica Rosenkrantz in the USA used 3D printing technology to make a very special and new dress. It will help with the problems of different styles of women's dresses.

The dress maker called the special dress a"4D dress" ". It is like the fabric(织物). It can turn into different kinds of shapes.

The company, in Massachusetts, the USA, also made a smartphone and an app(应用). They can help women to control their dresses. If women use the phone and the app, they can change the colour, the style and many other things of the dresses. Isn't it very interesting?

When she talked about her work, Jessica said, "There will be many more changeable dresses for women in the future. I am interested in making them too, I can't wait to make different kinds of new dresses for women."

This is a street crossing. There are red and green lights at each corner. Drivers must watch the lights carefully.

When there is a green light, the cars may go on. When there is a red light, the cars must stop.

They must wait until the red light changes (变成)to green. Then they can go on. Sometimes the cars want to make a right turn or a left turn. They can make a right turn when the light is green or red. But they must wait until the green light is shining (闪亮) if they want to turn left. Some people are color-blind (色盲的). They can't see the difference (不同点) between red and green. These people mustn't drive, or there may be an accident (事故) .We must keep our street safe (安全的).
