Many teachers believe that hands-on experiences are the best way to learn. A group of students in the United Sates is putting that belief to the test.

The students are from the Stevens Institute of Technology. They successfully designed and built a robot for discovering mines at the bottom of the sea. The underwater robot is called Perseus II. It costs about $15,000 to build. The students made the robot to answer a challenge from the U.S. Department of Defense（国防部）.

The students use a video game controller to direct its movements. Devices known as

thrusters enable the robot to go up, down and toward its target in the water. Video cameras on the robot send images back to a computer through a 13-meter-long cable(电缆). Perseus II also has a set of lasers(激光), they are used to measure the size of an object.

The robot is the creation of five college students. They worked for over six months to　 design and build Perseus II.

"Their goal was to go down and find the mine and not only just find it but provide information to an expert on the surface so he or she could make a decision whether it was something dangerous or not before they removed it," Michael DeLorne said.

Perseus II was successfully tested in Florida with similar robots built at other engineering schools. In a separate development, new students at the Stevens Institute of Technology have already started on the next project. It is a flying vehicle they are calling Perseus III.

1.Why did the five college students make the robot?

A. To go up, down and toward its target underwater.

B. To provide information to an expert on the surface.

C. To answer a challenge from the Department of Defense.

D. To prove hands-on experiences is the best way to learn.

A. a set of lasers　　 B. a computer

C. video cameras　　 D. a video game controller

3..What does the word “mine” in Paragraph 5 most probably mean ?

A. 宝藏　　 B. 海鱼　　 C. 矿井　　 D. 水雷

4.What can we infer（推断) about Perseus III according to the passage?

A. Perseus III may be used in the sky.

B. Perseus III has been successfully tested in Florida.

C. Perseus III will cost more money and time.

D. Perseus III and Perseus II are made by the same students.

There are many things you can do to improve your memory. Among them are many kinds of useful ways as well as taking special care of your health.

It is important that you make yourself excited to make your memory more active. You can do this by doing some new activities and by changing your daily habits. Learning a new skill helps your brain (大脑) to develop. When trying to remember something, you should pay special attention to the most important things about it. Do not allow other thoughts to enter your mind because this will reduce your chances of making right memories.

An excellent way to help memory is to connect information with pictures. Try to see the pictures in your mind. Taking notes and keeping a diary will also be helpful.

Healthy food and plenty of vitamins are necessary for your memory to work well. Drinking a lot of water also helps keep your memory. You must allow your brain to have enough sleep and rest. When you are asleep, your brain stores memory. Not enough sleep can cause problems with storing information. And being tired will also stop you from being able to think clearly and well.

In order to keep your mind on your work, you must be free from worry. Generally keeping fit and normal health checks are both important as well—not just for improving your memory.
