1 . If a pancake could dream, it might long for legs so it could jump off your breakfast plate in pursuit of a better, unchewed life. But legs aren’t necessary for something as flat as a pancake to jump around. A group of scientists have designed a pancake-shaped robot that can jump several times per second and higher than seven times its body height. The new robot named Hop, which swiftly jumps without feet, is an important contribution to the soft robotics.

Many ground robots move by rolling or walking. But it’s more efficient for robots to jump over obstacles (障碍物) than to go around them. Although jumping can offer some robots a competitive edge, engineering that ability has been a challenge for robotics researchers. Some soft robots that store energy can perform a single impressive jump very infrequently. Some lightweight soft robots that don’t store energy can jump frequently but can’t jump high or far enough to successfully cross an obstacle.

For inspiration, the researchers looked to gall midge larvae (瘿蚊幼虫) that miraculously throw themselves across distances 30 times as long as their loglike bodies. A gall midge larva bends its body and squeezes the liquid in its body to one end, making it rigid (僵硬的). The accumulation of liquid builds up pressure, and releasing the pressure sends it soaring (飙升). The robot’s body doesn’t resemble (像) that of a gall midge larva, but it jumps like one. Its body is made of two small plastic bags printed with electrodes; the front bag is filled with liquid and the back one is filled with the same volume of air. The robot uses electricity to drive the flow of liquid, which causes the body to bend and generate force with the ground, resulting in a jump. And the air bag imitates the function of an animal’s tail, helping the robot keep a stable position.

While the robot is currently restricted to Earth, it might be right at home exploring another planet. If this is true, the researchers robot might jump over dusty rocks and large holes on the moon or Mars, going where no pancake has gone before.

4 . How to Avoid an Internet Addiction

It may seem like everyone surfs the web these days. But if you can’t have interest in other aspects of your life because of the Internet, you may be on your way to an Internet addiction. You might fear you’re the only one who has experienced that feeling.    1     Luckily, there are some ways to avoid living your life in front of the computer.

    2    

More and more people in the world are becoming addicted to the Internet, and you are not the only one with this problem. So do not be embarrassed. Just be brave to admit that you are on your way to an Internet addiction. And then find others with the same problem and help each other beat it.

Set aside limited time for computer use.

Make sure not to turn it on too many times a week. If you have a laptop, make sure to put it somewhere that you can remember but not somewhere that you see every day. Try keeping the lid closed when you are not using it.     3       If you have a desktop PC, try not to go near it or put something over it like a sheet.

Call people instead of sending instant messages or texts.

If you are free on weekends, call friends and ask them to go outside to do something you enjoy, like playing a sport. This will take your mind off the computer.     4    

Use an alarm clock or timer (计时器).

Before using your computer, decide on a time limit such as 30 minutes. Set the clock or timer and make sure that you get away from the computer when the time is up. Alternatively create a shutdown timer on your desktop.     5    

A．Being addicted to it is quite normal.

B．Admit you are at risk of an addiction.

C．The truth, though, is that it’s quite common to be an addict.

D．When the computer is not looking at you, you are less likely to use it.

E．This can be programmed to shut down your computer after the set time.

F．If you have a problem on weekdays, phone your friends or ask for help in person.

G．This will prevent you from using the Internet so often or going on to another page.

5 . Everyone “talks” with their hands at least sometimes. Some people’s hand-talking, or gesturing (手势) matches their messages well. Other people like to make gestures that can be confusing. And still others don’t use their hands much at all. No matter which group you are in, it’s important to pay attention to your hand gestures while you are communicating. And also remember hand gestures can have cultural meanings.

A few years ago, I was a speaker at a conference in Lisbon, Portugal. It was my first time in Portugal, and I became immediately fond of the special pastries (糕点) that Lisbon and Portugal are known for. One morning I went into a bakery and ordered two of the pastries. I did so by holding up two fingers, similar to the “victory” or “peace” gesture in the United States. The person behind the counter put three pastries in the box. I later learned that the gesture for two would raise thumb and index finger. Even though my thumb wasn’t showing, the person behind the counter thought I was signaling for three.

I was lucky that I didn’t get into more trouble than an extra pastry. Many hand gestures are not universal. Before speaking in a country that you are not familiar with, do some research to find out which gestures might be misunderstood, not understood at all or rude.

1. Why did the author go to Lisbon, Portugal?

A．To taste pastries.	B．To take a holiday.
C．To attend a meeting.	D．To learn Portuguese culture.

2. What does the underlined word “universal” refer to in para.3?

A．Normal.

B．Independent.

C．Common.

D．Complex.

3. What can we learn from the author’s experience?

A．One should be careful when ordering food in Portugal.

B．Hand gestures may have different meanings in different cultures.

C．The person behind the counter understood the author’s gesture.

D．The person behind the counter cheated the author.

4. The author’s main purpose in writing the passage is to______.

A．tell us that hand gestures are not the same worldwide

B．explain the general use of gestures

C．ask us to use correct hand gestures in Portugal

D．share a funny story in Portugal
