You change the channels for the fourth time and realize that once again there’s nothing on television that gets your attention. Not a problem! Throw on some running shoes and comfortable clothes and go for a run.
One of the coolest things about the sport of running is that you don’t need expensive equipment(裝備). All you need is a good pair of running shoes and a safe environment. But just because you don’t need much equipment don’t be fooled into thinking the sport of running is easy. No one wakes up and decides to run a marathon without training.
Running makes your heart, lungs, and muscles stronger. It makes you know more about your body. Running also gives you energy by increasing your oxygen(氧氣) intake, so you don’t get sick easily. It can even help you keep your mind on school work because exercise helps you to think more clearly.
How do you take part in the sport if you don’t know much about it? Most schools offer cross-country and track programs, but there are also running clubs open to all ages. A simple Internet search can help you find some in your area. The programs show you how running can offer competition or just be for fun. They also teach runners to set realistic goals and take care of their bodies.
Runners have great respect for each other because they know how difficult the sport can be. If you go to a race, you’ll see people cheering for all the runners, from the first place finisher to the last place finisher. Running isn’t always about how fast you are or how far you’re going. It’s about getting out there and doing it. Taking part is more important than competition, and effort is recognized over gift.
If you’re looking for more than just a sport, running may be the perfect choice for you.

Which part of the world has the most nearsighted students? Just look around you–it’s East Asia. Nine in ten school leavers in major East Asian cities are nearsighted, according to the BBC. Experts say books and video games are not to blame. East Asian students, they say, aren’t getting enough sunlight.
People become nearsighted because their eyeballs grow out of shape and light entering their eyes cannot focus correctly. The body can produce a chemical called dopamine (多巴胺) to stop eyeballs from changing shape. And guess what scientists have just discovered? Sunlight can help our bodies produce more dopamine, reported AFP.
According to the study, primary school students in Singapore spend only 30 minutes outdoors every day; in Australia, by contrast, kids spend about three hours a day outside. As a result, fewer children in Australia are nearsighted–only 10 percent, compared with 90 percent in Singapore.
“Children in East Asia basically go to school... go home and stay inside. They study and they watch television,” Ian Morgan of the Australian National University told AFP.
But being a bookworm or a couch potato does not directly harm the eyes, added Morgan. “As long as they get outside, it doesn’t seem to matter how much study they do,” he explained. “There are some kids who study hard and get outside and play hard and they are generally fine. The ones who are at major risk are the ones who study hard and don’t get outside. As a result of massive (巨大的) educational pressures and the construction (構成) of a child’s day, the amount of time they spend outside in bright light is minimized.”
Experts suggest children should stay outside for two to three hours every day. This can include time spent in the playground and walking to and from school.
小題1:Which of the word has the similar meaning as the underlined phrase “nine in ten”?

A．many

B．few

C．some

D．most

小題2:What is the main reason for the large number of nearsighted students in East Asia, according to scientists?

A．Too much reading or gaming.	B．Lack（缺少）of sunlight.
C．Genetic reasons.	D．Lack of exercise.

小題3:What can we conclude from Paragraph 2?

A．Dopamine is a chemical that causes eyeballs to grow out of shape.

B．Dopamine can stop light entering the eyes from focusing correctly.

C．Spending time in the sun can make the loss of dopamine in the body.

D．The more dopamine a person has in their body, the better eyesight he or she has.

小題4:According to Morgan, what kind of people are most likely to suffer from nearsightedness?

A．Those who like watching TV.

B．Those who take exercise regularly.

C．Those who study hard and play hard outdoors.

D．Those who stay indoors studying all day

Smartphone ,poor sight
Look around and you’ll see people busy on their smartphones. Smartphones do make our lives easier . But have you ever thought about what they mean to you eyes?
According to a study ,half of British people own smartphones and they spend an average of two hours a day using them . There has been a 35% increase in the number of people in the UK who suffer from shortsightedness since smartphones were introduced there in 1997.
Staring at smartphones for long time gives you dry eyes. When looking at something in the distance ,your eyes automatically blink a certain number of times. However ,when you look at things closer to your face ,the blinking slows down . This reduces the amount of tears and causes discomfort in your eyes. Another bad habit is using smartphones in dark rooms before going to sleep . If you look at a bright screen while your pupils become larger ,too much light enters your eyes. This can do harm to the eyes and cause a disease called glaucoma.
While you’re probably not going to stop using to your smartphone,there are a few things you can do to protect your eyes. Hold your phone at least 30 continues away from your eyes when using it. Take a break every hour and try the following :look at something at least five meters from you and then focus on the tip of your nose. Repeat this several times. It should reduce the discomfort in your eyes.

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.

People enjoy taking trips. But what are the reasons they leave home? One reason is for education. People travel because they want to learn more about other people and other places. They are curious about other cultures. When people are tourists, they get a quick look at different ways of living. Even a short look at another kind of lifestyle is an important lesson. On a trip, a person can learn directly by visiting museums and historic spots. What does a tourist learn who sees the art museums, visits the historical palaces and other scenic spots in Paris and shops along the River Seine? He gets a vivid picture, a real life of one of the French people. He learns about their attitudes（態度）, how they feel about business, beauty and history.
What about the tourist who goes to Hong Kong? Does he get the same information that he could get from a book? He might read that Hong Kong is crowded, that there is less than 200 square meters of space for each person. But seeing and feeling the lack of space will impress him much more. He might read that there are nearly 200 vehicles for every kilometer of roadway. But the sight of so many vehicles parked along the roadside would be a much more vivid lesson. The tourist to Hong Kong will never forget the contrasts(對比，對照): the straight vertical lines of tall modern buildings and the moving lines of boats that people live in.
小題1:Why do people leave home to travel according to the passage?

A．For education.	B．For adventure.

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．

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

小題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

小題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

小題4:We can probably read this passage in a ____________

A．storybook

B．travel guidebook

C．movie poster
