根据短文内容，从题中所给的A、B、C、D四个选项中，选出正确选项。

What will the world be like if cars can drive themselves? Imagine seeing an empty car passing by on its way to pick up its owner or a car full of passengers who are reading, listening to music or even sleeping. The passengers in the car needn't worry about the road ahead.

Well, all of this could be the future of driving. There are several companies, including Google, Tesla, Mercedes-Bens, Audi, BMW, Volvo and Toyota, working on driverless cars. They are now in the testing stages (阶段). If the tests are successful, these self-driving cars could be available very soon. But how is it possible for a car to drive itself?

Modern cars are able to take the place of drivers during certain situations. For example, they can park themselves or slow down when they detect (发现) objects nearby. They can also control the speed if there are dangerous condi-tions, such as snowy roads. Scientists and engineers believe that, with the help of wireless signals (无线),cameras and GPS, creating a safe self-driving car might be possible in ten to twenty years.

Self-driving cars may help cut down the number of serious accidents caused by careless drivers or dangerous condi-tions. However, there are still some people who do not like the idea. American lawyer, White Drake, for example, doesn't believe these cars are safe. He thinks the possibility of the technology making a mistake will be too high.

A、the modem world B、scientists and cars C、self-driving cars D、cars and accidents

The world is not only hungry but also thirsty for water. This may seem strange to you, since nearly 70% of the earth's surface is covered with water. But about 97% of that is sea water or salt water. Man can only drink and use the other 3% of fresh water from rivers, lakes, underground and so on. And we can not even use all of that because some of it has been made dirty.
Earth Day is April 22. But on all other days, we must also remember how important water is. The water that we use is the most important natural resource on the earth. Today we face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too.
How do cars and factories make our water dirty? First they pollute the air. Then when it rains, the rain water makes our drinking water dirty. Dirty rain, called acid rain is also bad for plants, animals and buildings. Scientists say that in 30 years, more than half of the people in the world won't have enough clean water. We have to learn how to stop wasting water. One of the first steps is to develop ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer system (下水道). From there it returns to the sea or goes underground.
But even though every large city reused its water, we would still not have enough. So we should make use of sea water by removing the salt in it. If we can take these steps, fresh water won't be used up.

   Robots seems very new to most people. But they have a long history. The first one was made by a Greek inventor, you may see robots are used in factories. They are used to do many dangerous, difficult or boring jobs.
   Some people can't look after themselves and robots are used to help them. For example, some people can't see, many of these people use a dog to help them. In the future, robot dogs might take the place of these guide dogs.
   Robots are also used in American hospital. At one hospital, a robot takes meals from the kitchen to sick people's rooms. It never loses its way because it has a map of the hospital in its computer system.
   In the future, robots will work in space. But robots will never take the place of human being. They can, however, help us in a lot of different ways.

What does it feel like to break a bone (骨头)? It's different for everyone, but the pain is often sharp (严重). If the break is small, however, the person may not feel much pain at all. If you think that you or someone else has broken a bone, the most important things to do are to stay calm, make the hurt person comfortable, and call the doctor. Do not move the injured body part since movement could make it worse.
To treat the break, the doctor will need to take an X-ray. This gives the doctor the information he or she needs to set (接上) the bone: to put it back to its normal place. If the bone is large or it is broken in more than one place, the doctor may need to use metal pins (钢钉) to set it. After the bone has been set, the next step is usually putting on a cast, the special, hard thing that will keep the bone in place for a month or two.
ypur bones are excellent at healing themselves. Broken bones will produce many new cells (细胞) and tiny blood vessels (血脉). These cover both ends of the broken part, and close up the break until the bone is as whole and strong as before.

     The sun is a huge, hot and bright star. It is important because without it there would be no life on the earth. The sun gives us light and heat.
All living things depend on the sun for their growth. Plants need light and heat to grow. They use the light from the sun to make food. But we human beings cannot make food by our own bodies from the sun. All the food we eat comes from plants in a food chain(链) . And the food chain starts with the sun . For example.
sun —→ potatoes —→ chips
sun —→ corn —→ hens —→ eggs
sun—→ wheat —→ bread
     Animals need sunlight, too. Just like us, their food comes from plants in food chain, which begins with the sun. For example,
Sun → leaf → caterpilllar(毛虫) → bird
Sun → seaweed(海藻) → small fish → whale(鲸)
     With the help of sunlight, we can see things during the day. Even when the sky is cloudy, the sunlight is very strong and it shines through the clouds. If there was no sun, it would be dark all the time.

What will man be like in the future — in 5,000 or even 50,000 years from now? We can only make a guess, of course, but we can be sure that he will be different from what he is today. For man is slowly changing all the time.

Let us take an example. Man, even five hundred years ago, was shorter than he is today. Now, on the average, men are about three inches taller. Five hundred years is a relatively (相对地) short period of time, so we may suppose that man will continue to grow taller.

Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity (容量.) As time goes on, however, we shall have to use our brains more and more and finally we shall need larger ones! This is likely to bring about a physical change too. The head, especially the forehead, will grow larger.

Nowadays our eyes are being used too much. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man's eyes will grow stronger.

On the other hand, we tend (有…的趋势) to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive (敏感的) because they are used a great deal in modern life.

What about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both men and women are probably to be hairless!

Perhaps, all this gives the impression that future man will not be a very attractive (有吸引力的) person to look at! This may well be true. All the same, besides these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and feelings similar to our own.

Every day there is less and less space on Earth for rubbish. Yet every day we make more and more rubbish. What can we do? We can recycle some of our rubbish. Recycling means that the rubbish will be made into something that can be used again.

Recycling helps Earth. And it saves space in rubbish dumps(垃圾场). Half of everything that we put into landfills could be recycled instead. In fact, most things made of paper, metal, glass and plastic can be recycled.

Paper can be broken into small pieces and made into new paper. Steel and aluminum cans(金属罐) can be melted down(熔化) and made into new cans. The same is true of glass bottles. This can be done over and over again. Recycling doesn't take as much energy as making these things the first time. So we can use less of Earth's fuel resources.

Plastic can be melted down, too. Then it can be formed into park benches(长椅), playgrounds and so on. Some people call plastic the "wood" of the future. Things made of plastic will last about 400 years—even if they stay outside in the weather. No wood can do that!
