Last Monday, we were having our Chinese class while the teacher suddenly slip and fell. We were all worried about her. One of the boy carried her on the back, under the help of some others, to the clinic immediately. It turned out that her right leg was breaking and she had to stay in hospital. The following day, we went to visit her with flowers and fruit. Seeing her laying in bed with leg wrapped in bandages, we felt sorry for her and hoped that she would recover soon. Lucky enough, this Thursday she returned back to the class in a wheelchair to give us lessons. We were both deeply moved and proud of having such a responsible teacher.

【題目】Do you know how it is when you see someone yawn and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神經(jīng)元）in our brains.
Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate (模仿)it, whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actions，they also tell us that there is a biological basis for the way we understand other people.
Mirror neurons can undoubtedly be found all over our brains，but especially in the areas which relate to our ability to use languages，and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to (for example: "The hand took hold of the ball"), the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).
Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.
Research into mirror neurons seems to provide us with even more information concerning how humans behave and interact(互動).Indeed, it may turn out to be the equivalent (相等物)for neuroscience of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does—well, perhaps you'll understand why.

【1】Mirror neurons can explain _____.

A. why we cry when we are hurt

B. why we cough when we suffer from a cold

C. why we smile when we see someone else smile

D. why we yawn when we see someone else stay up late

【2】The underlined word "triggered" in the third paragraph probably means “____”.

A. set off B. cut off C. built up D. broken up

【3】We can learn from the passage that mirror neurons _____.

A. relate to human behavior and interaction

B. control human physical actions and feelings

C. result in bad behavior and social disorders

D. determine our knowledge and language abilities

【4】What is the passage mainly about?

A. Ways to find mirror neurons.

B. Problems of mirror neurons.

C. Existence of mirror neurons.

D. Functions of mirror neurons.

【題目】Dear Editor,

I am writing tell you about the discussion we’ve had about whether it is necessary of middle school students to have mobile phones. Most students think this is more convenient for them to keep in the touch with their parents and classmates. And what’s much, it’s a fashion. However, most teachers think middle school students are not old enough to control them. It is a waste of time for students to play games and sending messages on their mobile phones. Therefore, it is easy to make students contact with each other. In my opinion, following the fashion was understandable. But as middle school student, we should put all our energy into our study.

Yours truly,

Mary
