PowerPoint Presentations(PPT)are taking the place of writing on the blackboard with chalk. Someday, will robots take the place of human teachers?

In Japan, a robot is going to enter classrooms to help teachers. Last week the Japanese company Honda Motor Co. showed the public its robot at a Tokyo museum. The robot's name is Asimo. Students will see Asimo in science classes and learn the wonders of science.

Asimo is 130 centimeters tall with a round head. It can jog, walk up stairs and wave. It can also avoid things on its way and have simple talks with you. Asimo is an experienced worker for humans. It has worked as a guide in showrooms. But this will be the first time it works as a teaching assistant in classrooms and in formal teaching!

How will Asimo help in class?A teacher explained the way Asimo worked to students in last week's show. Asimo has sensors(感应器)inside its body to keep its balance.

The smart Asimo tilted(倾斜)its body when it stood on a shaking platform(平台). Asimo kept its balance. But a wooden person beside Asimo fell(See the above picture).

When you walk, you pass your weight from the heel to the toe. The Japanese teacher explained this with Asimo at the museum. He moved the robot in slow move. Asimo made learning science more interesting for students!

Asimo will soon help teach thousands of primary students and junior high schools in two Japanese cities. Hopefully, robot teachers will arrive in our classrooms in China one day.

Think of a simple object—a piece of chalk, for example. Are you remembering its name, its shape, its color or its size? Are you remembering what it is used for, or the sound it makes when the teacher writes on the blackboard? Scientists say that memory includes different parts of the brain, such as language and the ability of sense. They believe that you begin to create a memory when you notice something you’re your senses. Then messages are sent to different brain cells, which join together to form connections. A new connection goes into your short—term memory. It is stored there for about 30 seconds, and then it is either lost or stored in your long—term memory.

Having a good memory means making lots of connections and storing them in your long—term memory. To do this, you need to keep your brain in good shape. Eat plenty of brain food such as fish oil, fruit and vegetables. Laughter also makes your brain more active. Also, don’t forget to exercise. So do some sports or just move around a lot in the house. Finally, get plenty of sleep. This will make your memories grow stronger.

When you want to remember new information, you must pay special attention. Use your senses--sight, smell, hearing and touch-and keep repeating the information. To do well in your exams this year, turn off the TV, silence your mobile, and review your work regularly. To remember something special, use your imagination to create visual(视觉的) connections. For example, you need to take a pencil, an eraser, your ID card and chips to your next exam. Imagine the ID card as the body of an animal, the pencil its long neck, and the eraser its head. Your animal is hungry, so now imagine it eating a bag of chips. It may sound crazy, but its fun and it works. Another way is to do something different to your room. Turn a picture upside-down, or tie a sock around the door handle to remind(提醒)yourself of something to remember!

1.At the beginning, the writer gives an example to _________.

A. lead in the topic of the article　　　　 B. show the importance of chalk

C. let readers remember the word　　　 D. make readers know his favorite

2.How many ways are mentioned to have a good memory in Paragraph 2 ?

A. 2.　　 B. 3.　　　　 C. 4.　　　　　　 D. 5.

3.The main idea of the third paragraph is___________.

A. how to do well in exams　　　　　　 B. how to remember new information

C. why to review your work　　　　　　 D. what to eat to make memories stronger

4. Which of the following is TRUE according to the passage?

A. Memory has nothing to do with languages.　　 B. Laughter can help to improve our memory.

C. A picture of eating chips is the most useful.　　 D. Our brain is difficult to keep in good shape.
