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 (神经元) 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 (行使职责)． 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 (相对论) 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

What is the first thing you want to do when you see someone yawn（打哈欠）？You want to yawn, too! Yawning is contagious.
Scientists have found that all people yawn. Babies start to yawn even before they are born. The earliest yawn takes place when a baby is still inside its mother. When young children are about one year old, they start to yawn when they see others yawning. That’s why scientists seem to think yawning is contagious.
It’s no secret that yawning is contagious, but why do we yawn? Well, scientists are not really sure.
Some think we yawn because we feel bored. Recently scientists studied two groups of students between the ages of 17 and 19. One group watched music videos, and the other watched a boring color test. Scientists compared the numbers of their yawns and found that the color test group yawned more times than the video group.
Another reason for yawning has to do with breathing. Some scientists believe that when we are bored or tired, we breathe more slowly. As our breathing slows down, we cannot get rid of （去除）enough carbon dioxide, our bodies will tell the brains（大脑）to breathe deeply. The result is a big yawn.
In 2007, scientists suggested a new reason. They said that the reason why people yawned was to cool down their brains. These scientists found that people who were warmer than others yawned more often.
Scientists are still trying to find out why yawning happens and why it is so contagious. But they are only sure that when one person yawns, almost everyone else nearby wants to yawn, too.
1.The underlined word “contagious” in Paragraph 1 means _________.
A. helpful to our health
B. passing from one person to another
C. hard to understand
D. getting into one trouble after another
2.According to the scientists, people start to yawn when they are _______.
A. born B. one year old C. 17 or 19 years old D. inside their mothers
3.Which of the following are the possible reasons for yawning according to the passage?
①People yawn because they are bored
②People yawn to catch others’ attention
③People yawn to cool down their brains
④People yawn to get rid of carbon dioxide.
A. ①②③ B.②③④ C.①②④ D.①③④
4.We can probably read this passage in a ____________
A. storybook B. travel guidebook C. movie poster D. science magazine

Do you know 3D movies? When you see one, it’s like the story is happening in front of you, and you are a part of it. 3D movies are amazing to watch, but do you know how to make them, and why you need to wear a pair of 3D glasses? To understand these questions, let’s do an easy experiment.
Put a finger in front of your eyes.
Cover your left eye and look at the finger.
Cover your right eye and look at the finger.
What do you see? The finger you see with your left eye is in a different position from the one you see with your right eye. This means you get two images(图像) when you look at something with both your eyes. To make a 3D movie, people have to get two images at the same time, so they use two video cameras. When playing a 3D movie, they use two projectors(放映机) at the same time. This brings two images together on the screen. Then, we use 3D glasses to separate(分离) the two images(1). One image enters one eye and the other image enters the other eye.
Then our brains put the two images together. This way, we get 3D pictures(2).
1.判断正误（“T”表示正确，“F”表示错误）You are a part of the story when you see 3D movies.
2.完成句子3D movies are exciting to watch, but you need to ____________________________.
3.简略回答问题 How do people get two images at the same time to make 3D movies?
_______________________________________________________________________
4.划线句子(1)提问_______________________________________________________________________
5.将文中划线句子(2)译成汉语。_______________________________________________________________________

You may never know how valuable something is when it can not be fixed. And it could be a lovely moment you lose forever.
I grew up with very practical parents. My mother washed aluminum foil (铝箔纸) after she cooked in it, then reused it. She was the recycle queen, before they had a name for it.
My father was happier getting old shoes fixed than buying new ones. Their marriage was good. Their dreams focused. Their best friends lived so near. I can see them now, Dad in trousers, T-shirt and a hat and Mum in a house dress, lawn mower (割草机) in one hand, dishtowel in the other.
It was the time for fixing things — a curtain rod (杆), the kitchen radio, the oven door, the hem (褶边) in a dress — things we kept.
It was a way of life, and sometimes it made me crazy. I wanted just once to be wasteful. Waste somewhat meant affluence (富裕). Throwing things away meant you knew there would always be more.
But then my mother died, and on that clear summer’s night, in the warmth of the hospital room, I was struck with the pain of learning that sometimes there isn’t any more.
Sometimes what we care about most gets all used up and goes away… never to return. So, while we have it, it’s best we love it, care for it, fix it when it’s broken, and heal it when it’s sick.
This is true for marriage, old cars and children with bad report cards, dogs with bad hips, aging parents and grandparents. We keep them because they are worth it, because we are worth it.
1.The writer really wanted to tell us .
A. her mum was the recycle queen.
B. her dad liked fixing old shoes.
C. throwing things meant there would be more
D. we should cherish (珍惜) what we care about while we have it
2.What does the underlined word “struck” mean?
A. knocked B. touched C. stuck D. caught
3.Which of the following is NOT mentioned according to the passage?
A. Fixing things is a way of life.
B. Waste somewhat meant affluence.
C. The writer’s family was very poor.
D. The writer’s parents were practical.
