Do you know how it is when you see someone yawn (打哈欠) and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, obviously it’s because we have mirror neurons (神經元) in our brains.

Put simply, the presence of mirror neurons suggests that every time we see someone else do something, our brains model after 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 (行使職責). 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 ever more information about how humans behave, communicate and spend time together. Indeed, it may turn out to be nearly the same important thing for neuroscience as what Einstein’s theory of relativity (相對論) was for physics. And the next time you have the strong feeling 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 catch a cold

C.why we smile when we see someone else smile

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

2.The word “triggered” in Paragraph 3 probably means “______”.

A.set off

B.cut off

C.broken out

D.found out

3.We can learn from the passage that mirror neurons _______.

A.relate to human behavior and communication

B.decide our knowledge and language abilities

C.result in bad behavior and social disorders

D.control human actions and appearances

4.What is the passage mainly about?

A.Ways to find mirror neurons.

B.Problems of mirror neurons.

C.Discovery of mirror neurons.

D.Functions of mirror neurons.

Countless people long to make a difference this holiday season, yet they don’t realize that opportunities to make a difference are everywhere. Here are some ideas to get you started.

Organize a blank drive

It is cold outside, but imagine how thousands of homeless people may feel without a home of their own, or even a blanket to keep them from the cold. Organize a blank drive for your local homeless, and ask around for donations!

Practice random acts of kindness

I’ll never forget the time when I went to pay for my Dr. Pepper, but the server resisted, saying my bill was paid by an anonymous(匿名的) guest. It’s this random act of kindness that restores my faith in humanity. Bless someone by paying for their drink at Starbucks, or praising them! If you live somewhere where it snows, shovel your neighbor’s snow out of their driveway for them! Whether it is as simple as praise or as complex as paying the bill, you’ll never know how far your impact will reach.

Say thank youust a simple thank-you can make somebody’s day, especially if they feel like their work is never noticed. Cultivate(培養)a smile on their face by being sincere and grateful for all that they do.

Use your talents to help the community

The best way to show your appreciation for people is by using the talents and skills you have to bless others. For me, I love to coordinate(協調)events and write , and so my way of reaching out to the community is through writing articles and creating awareness about problems we face today. If you can bake, make some delicious cookies for people to enjoy! If you can knit, put your talents to use by making clothes for children in foster care. Any talent can be used to help the community in meaningful ways.

Wish you a happy, healthy and helpful holiday season.

1.If you join a blank drive, you can _________.

B. do something unnoticed by people

C. make someone feel good all day

D. help someone to solve problems

4.What is the author’s talent?

A. Sewing B. Writing
