Have you seen Avatar?It’s a popular movie this year. It is three-dimensional(3D), so you may have to wear a special pair of glasses to see it. The 3D glasses make the images(圖像) from the movie look like they are coming straight at you.
More and more 3D movies are coming to theaters. 3D TV sets have been produced in Japan now. Three-dimensional technology can make TV and movies more exciting. But people with eye problems may get headaches if they spend too much time watching 3D movies.
When we look at an object(物體), each eye sees it at a different angle(角度). Our eyes send the two images to our brain(大腦), and the brain puts them together. That’s how we see depth(深度). So when we watch a 3D movie, one film projector(投影機) projects a left eye image and the other projects a right eye image. 3D glasses allow us to see a different image in each eye.
There are a lot of people walking around with very less serious eye problems. Under normal situations, the brain can adjust to their eyes so they can see things normally.
But when they are watching a 3D movie, the images projected to their eyes can’t be put together by their brain. So the brain needs to work harder at reading the images. That makes it easier for these people to get headaches.
Dr John Hagan, an eye doctor in Kansas City, said some people who do not see depth normally cannot see in 3D at all.
小題1:When people want to watch a three-dimensional movie, they need          .
A. a ticket                  B. a pair of 3D glasses             C. an earphone
小題2:Three-dimensional technology uses         film projector(s) to project one movie at the same time.
A. one                     B. two                         C. three
小題3:According to the passage, if we look at an object by only one eye, we can’t judge the       excatly.
A. image                   B. angle                         C. depth
小題4:Which statement is TRUE according to the passage?
A. In the near future, people can enjoy 3D movie by watching TV at home.
B. Whenever you wear a 3D glasses, you can see objects more clearly.
C. People who have something wrong with their brain can’t read the images of 3D movie.
小題5:The main idea of this passage is            .
A. how to use 3D glasses to watch a 3D movie.    
B. 3D glasses make the movie seem alive
C. not everybody can enjoy 3D movies.

The H1Nl virus has been spreading world-wide,it is important for us to know how to control it.Please pay attention to the following points:
1.Don't touch your face.Above all,keep your hands away from your eyes,mouth and nose,all of which serve pathways(途徑) for the viruses(病毒) to enter your body.
2.Wash your hands.If you have to touch your face,wash your hands,getting under the fingernails for 20 to 30 seconds with hot soap and water before.Soaps with surfactants(表面活性劑) can deal with flu viruses.
3.Cover your nose and mouth.When someone sneezes or coughs,liquid(液體) drops with flu viruses as far as three feet through the air and land on your nose and mouth,so it's best to keep at least an arm's length distance when talking to someone who shows signs of infection(感染).In order to protect others,cover your mouth and nose with a tissue(紙巾) when you cough or sneeze,and clean your hands afterward.Viruses can live for hours,or even longer when on the skin or other surfaces such as keyboards.
4.Consider buying a mask in case you need it in the future.Some research suggests that masks reduce the risk of getting the flu viruses by as much as 80%.But it also suggests that if you don't wash hands,the mask doesn't work well.So wash your hands and use the mask,especially wearing face masks in crowded places is also useful.

It’s in the 2010s.You feel sick, so you go to the doctor. She checks your fever, looks at your throat, and asks what you’ve been thinking about lately. When you leave, she gives you some medicine, but also a list of thinking skills that you are supposed to practice daily. She says that the way you think is causing some of your illness.
Doctors and other scientists who study the human mind and try to explain why people act in the way that they do, called psychologists (心理學家), are starting to believe it. You know that your brain (腦) is connected to every part of your body through your nervous system (神經系統). Now scientists have proved that how you think and feel can have an influence on the health of your body.
Stress is caused whenever there is a problem or a change in your life. Of course, everybody has stress more or less; nobody’s life is perfect. In fact, stress is necessary. Without stress, we would never learn anything or grow or change. We would probably be bored to death. But too much stress can hurt you. It can weaken your body’s protection so that you are more likely to catch diseases. It can even make you more likely to have an accident.
When you feel stressed, your brain sends a message to your body to produce a chemical called adrenaline (腎上腺素). Adrenaline speeds up your breathing and your heartbeat. Today you have a different kind of stress. Problems like endless homework or troubles with your family are the kind of things you can’t fight or run away from, so you don’t use up all that adrenaline. It just stays bottled up inside you, and that’s what can do something bad to you.
What can you do about stress? First, you can try to find ways to change things so you aren’t under so much stress. You can set up a plan to finish homework or go to a doctor or a psychologist to try to work things out with your family or your friends. But sometimes you can’t change a stressful situation. Sometimes you don’t even want to. A big change might be a good change, but it will still be stressful.
The link (關聯) between your body and brain works in two ways. Your body can help your mind deal with stress. If you are under stress, you need to take especially good care of your body. It’s important to get enough sleep and eat nutritious (有營養的) meals. Some people take a vitamin-mineral pill every day. Another thing that you can do is daily exercise. If you go walking or do aerobic dancing or work out at the gym (體育館), you give your body a chance to burn up some of that adrenaline. Of course, a person who isn’t used to much physical activity should start slowly. Anyone with a continuing physical problem should check with a doctor before starting any exercise programs.
小題1:Which of the following is TRUE according to the passage?
A.You shouldn’t go to the gym if you are under stress.
B.One can do his homework to burn up adrenaline.
C.Disease and accidents are caused by stress.
D.Everyone needs stress to improve himself.
小題2:From the last sentence of Paragraph 5 we can infer (推斷) that _____________.
A.it’s difficult to change a stressful situation
B.it’s not stressful when a good change takes place
C.a big change will cause another stressful situation
D.a stressful situation can’t be changed without any effort
小題3:What is probably the best title for this passage?
A.The Body-Brain LinkB.The Causes of Stress
C.The Advice on HealthD.The Nervous System

I love my Blackberry mobile phone – it’s my little connection to the larger world that can go anywhere with me. I also love my computer, as it holds all of my writing and thoughts. However, I know there are times when I need to move away from these things and truly communicate with others.
I teach a course called History Matters in college. My goals for the class include a deep discussion of historical subjects and ideas. Because I want students to fully study the material and discuss with each other in the classroom, I have a rule – no computers, iPads, phones, etc. When students were told my rule, some of them were not happy.
Most students think my reasons for this rule include negative experiences in the past when students made wrong use of technology. There’s a bit of truth to that. I’ve seldom had students make wrong use of technology in my classes; however, I have been e-mailed by students while they were in other teachers’ classrooms.
Some students think that I am anti-technology. There’s no truth in that at all. As I noted above, I love technology and try to keep up with it.
The real reason why I ask students to leave technology at the door is I think there are very few places in which we can have deep conversations. Interruptions (中斷) by technology often break students’ thoughts and make them depend too much on outside information for ideas. I want students to dig deep in themselves for ideas. I want them to push each other to think differently and to make connections between the course material and the class discussion.
I have been teaching my history class in this way for many years and the evaluations (評價) show student satisfaction with the environment that I create. Students realize with deep conversation and difficult tasks, they learn at a deeper level – a level that helps them keep the course material beyond the classroom.
I am not saying that I won’t ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I will continue my plan. A few hours of technology-free dialogue is just too sweet to give up.
小題1:The writer’s rule for his History Matters class is ____.
A.discussing historical ideas deeply
B.studying and discussing the materials
C.leaving technology out of the classroom
D.making right use of technology in class
小題2:The word “negative” in Paragraph 3 means ____.
A.similarB.unforgettableC.specialD.unpleasant
小題3:What can we infer from the passage?
A.Students make right use of technology in other teachers’ classes.
B.The classroom is one of the good places to have deep conversations.
C.The writer encourages students to agree with others after discussion.
D.Students are unhappy with the writer’s way of teaching history.
小題4:The writer wants to tell us that ____.
A.technology has different influences in different classes in college
B.technology makes it difficult to have true communication in class
C.history classes can help students to develop their deep thinking
D.it is time for him to give up his teaching method in history class

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(大腦)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.
小題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

Germs(細菌) are everywhere. You can’t see them, but they are on your desk, on your computer, and even in the air! Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.

Warmer Weather Brings Germs
The world’s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches,  fever, and can even kill people.
Under Your Skin
Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
Fighting Germs
Your immune system protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells(細胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs. What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.

A.kill germsB.carry germsC.protect germsD.love germs
