There are robots all around us. Some do very complicated jobs like flying airplanes and driving subway trains. And some do one simple job. When an automatic washing machine is switched on , water pours in. The machine waits until the water is warm enough for washing clothes. It does this by “feedback(反馈)” . Information about what is happening is feedback into the robot to tell what to do next. Our eyes, ears and other senses are our feedback. They tell us what is going on around us . So robots are like human beings in two ways.

They work and they have feedback.

In some ways robots are better than human beings. They work quickly and do not make mistakes. They do not get bored doing the same job over and over again. And they never get tired. So robots are very useful in factories. They can be taught to do many different jobs. First their electronic brain must be shown how the job is done, A person moves the robot’s “arms” and “hands” through each part of the job.

The most intelligent robots can move and see. Their eyes are cameras. Their fingers can feel shapes and sizes of the objects. These robots have computer brains linked to their eyes and fingers, which control their actions. The expensive robots are used in scientific research. They do such jobs as handling radioactive materials.

1.In this passage the author tells us that________.

A. robots are very popular               B. there are various kinds of robots

C. we see robots only at certain times      D. robots can be easily controlled

2.What does the author seem to inform you about robots?

A. They should be greatly improved

B. They will probably take over in the future

C. They are very hopeful and useful to humans

D. They are machines that break down a lot

3.The author says that in industry________.

A. robots break down a lot     B. robots can do many jobs

C. robots only get in the way   D. robots sometimes cause troubles

4.The fact that a robot never gets bored doing the same job means that ________.

A. it is very much like human beings  B. it can do boring jobs for people

C. it will never bore people          D. it will work much better than human beings

Free energy is everywhere around us. There are many ways to make and collect energy from various sources like sun, wind and water. People also realize that everyday stuff can be a source of energy too. For example, riding a bike, running or just walking, etc. We simply have to change our way of thinking if we want to change the world.

So comes the idea of solar roadways. Are they the road of future? Why use roads just for driving and collecting tolls (过路费)? Why don’t we use them for collecting energy?

The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel. So how do these future roads work?

The Solar Road Panels will contain embedded (嵌入的) LEDs which “paint” the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour (绕行) ahead. The road will be able to sense wildlife on the road and can warn drivers to “slow down”. There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving.

Replacing asphalt (沥青) roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change. Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips.

We just can’t wait to see more of these roads all over the world in the near future.

1.The first paragraph serves as a(n)______.

A. argument      B. comment       C. explanation      D. background

2.Which of the following is NOT true of LEDs?

A. They color the road lines.

B. They are embedded in the Solar Road Panels.

C. They are beneficial for nighttime driving.

D. They can provide instant instructions.

3. When some animals are on the solar road, what will the road do?

A. Guide them to a safer place.           B. Remind drivers to drive slowly.

C. Frighten them away from the road.      D. Advise drivers to choose another way.

4. From the text, we can know that the Solar Road Panels can______.

A. provide heat for drivers in winter

B. guide drivers who get lost on the highway

C. melt snow and ice soon in winter

D. help drivers see the road clearly in the sun
