Just put your special clothes on in the morning and you could jump 3 meters into the air and even carry more than 60 kilograms without getting tired. The walk to school would be very, very easy. Such supercharged clothing is one of the products that could be created using "wearable robotics” technology.
Designed to improve a person's senses and skills, the device could be as simple as a hearing aid. Or it could be a full-body suit that senses what you're going to do, then helps you do it better.
“A superman suit would be the final result in wearable robot i cs ”，s a id Francois Pin, head of robotics and energy systems at the Oak Ridge National Laboratory(橡树林国家实验室), US. While these suits are at least ten years away, in some areas the technology is already in use.
Researchers are developing artificial- arms and legs that allow old，disabled or injured people to move freely. Thus US Army is interested in using wearable robot legs to help soldiers run faster, carry more equipment and be stronger in battle. Jobs that involve lifting heavy loads or saving lives from the rubble of an earthquake could also become much easier.
A robot is a device that responds to a command. You're probably with simple robots, such as toy cars or airplanes that respond to buttons you push on a remote control.
Wearable robotics goes further. Instead of just receiving information through a wire or remotecontrol- the robotic device can send information back to its controller.
Suppose you wore a sleeve that has sensors where your joints are. Every time you move your arm, the sleeve senses your movements and sends the information to a robot, which then moves its arm just as you did. When the robot hits or touches something, it sends a signal back to the sleeve and you sense the action.
In this way，scientists are working to wrap the robot around the person. Their goal is to make the sleeve, shoe or suit help you do what you want to do.
1.Which of the following can replace the underlined word “supercharged” in Paragraph One?
A, expensive B. overcharged C. advanced D. full of electricity
2.Products resulting from this wearable robotics technology do not include _______.
A．remote controls B．hearing aids C．wearable robot legs D．superman suits
3.From the passage, we can infer that________.
A．it will be ten years before robotic devices are in use
B．the wearable robotics technology has been employed in some areas
C．the robots in the robotic devices will do whatever you want to do
D．people must become lazier and less healthier in the future

I had never seen sand dunes（沙丘）before. If you go to the seaside in Britain, you may see some small hills of sand, but nothing very impressive. Of course, Africa is home to many beautiful “sandscapes”, but I was in China, so I went to Dunhuang.
I had spent my first day looking at the beautiful Mogao caves. Now I wanted to experience something very different.
I have been walking in Asia, Europe and America, but nothing prepared me for walking over hills of sand. Whenever I took a step up a hill, my feet would sink into the sand and move backwards. Sometimes it seemed as if I were moving in the wrong direction.
I wanted to see the sunset so I had to climb to the top of the highest sand dune. The sun was beating down upon my back as I walked slowly over the sand. Some plants had managed to survive in the dry ground but not many.
As I climbed higher, the hills of sand became steeper and my feet started to slip further backwards. I ended up with my hands and knees, crawling (爬行)upwards through the top. I just let go if I would fall the way down. But I refused to give up: inch by inch, I made my way to the top of the sand dune.
When I got there I was amazed by what I saw. The sand formed a very sharp point, just like a knife-edge. One side of the dune was bathed in sunshine, the other covered by shade. As I looked into the distance, the same pattern was repeated on all of the hilltops, and the difference between dark and light was beautiful.
As the sun began to sink, the shadows grew longer and the light became warm and orange. The wind had come to life and sand was blown against my legs as I walked along the dunes. Soon it was getting dark and I could only just make out the line of footprints that marked my journey to the top of the hill. I slowly made my way down to the bottom, my path lit by the dying sun.
1.The author probably went to climb the sand dunes __________ after he arrived at Dunhuang.
A. on the afternoon of the first day B. on the afternoon of the second day
C. on the evening of the second day D. on the evening of the first day
2.Which of the following statements is NOT true?
A. Africa has many beautiful sand dunes.
B. The author could see nothing but his own footprints on his way back.
C. The author had seen some kinds of sand dunes before he visited Dunhuang
D. What attracted the author most was that the sand formed a very sharp point.
3.The author got to the top of the highest hill of sand _____________.
A. on his hands and knees all the way
B. with falls to the bottom many times
C. on his hands and knees in the last leg (一段旅程)
D. with a few rests all the way
4.The author mainly wants to tell readers about_____________.
A. the beautiful sunset B. his experience of climbing the sand hills
C. the joy of traveling in nature D. the difficulty of climbing the sand dunes
