Spending two or three hours playing outdoors each day can reduce the chance of becoming short-sighted(近视), a research shows. It challenges the belief(信念) that short-sightedness is caused by computer use, watching TV or reading in weak light.
The Australian government researchers believe that the sunlight is good for people’s eyes. They studied the vision(视力) and habits of 100 seven-year-old children in Singapore and Australia. In all, 30% of the Singaporean children were short-sighted—this rate(比率) was ten times higher than Australian children.
Both groups spend a similar amount(数量) of time reading, watching television and playing computer games. However the Singaporean children spent an average (平均) of only half an hour a day outdoors—90 minutes less than the Australian children.
Professor Ian Morgan, from the Australian Research Council’s vision Centre, said, “Humans are naturally long-sighted, but when people begin to go to school and spend little or no time outdoors, the number of short-sighted people gets larger. We’re also seeing more and more short-sighted children in cities all around the world and the main reason may be that city children spend less time outdoors.
Daylight can be hundreds of times brighter than indoor light. But why does playing outside prevent us from becoming short-sighted ? Scientists believe that natural light has a special chemical(化学物质) which stops the eyeball from growing out of shape and prevents people from becoming short-sighted.
So be outdoors. It doesn’t matter if that time is spent having a picnic or having sports.
How much time did the Australian children spend outdoors on average according to the research?

A.30 minutes. B.60 minutes.
C.90 minutes D.120 minutes.

Which of the following is TRUE according to the passage?

A.If people spend less time outdoors, they will certainly become short-sighted.
B.There are fewer short-sighted Singaporean Children than Australian children because
they have more knowledge of protecting their eyesight.
C.There will be fewer risks of getting short-sighted if people spend two or three hours a day playing outside.
D.When people begin to go to school, they will become long-sighted.

What is the fifth paragraph mainly about?

A.Why natural daylight has a special chemical.
B.Why daylight prevents people from becoming short-sighted.
C.Why daylight is much brighter than indoor light.
D.What the special chemical which can stop eyeballs from growing out of shape is.

Nobody likes making mistakes. But, no one is perfect. If you can learn from mistakes correctly, they can move you forward. Therefore, we should analyse how you can learn from them.
If you have made mistakes that harm other people, it is important to offer a sincere apology (道歉)in person. A good apology will likely make the other person forgive you. If you refuse to apologize, the person hurt by you will hold it against you.
If you go through life afraid to make a mistake, you will spend most of you life doing nothing. There is no harm in making mistakes; it is an essential part of going forward. The more duties you take, the more likely you will make mistakes.
Unluckily, it is our natural instinct(本能) to justify(为……辩解) our actions. When you make a mistake, you will first blame someone else. When mistakes are made, the boss is unlikely to be interested in justifications. Sometimes it is best to say, very simply--yes, I made a mistake.
Mistakes happen for various reasons. To avoid(避免)repeating them, you need to understand the main reason. For example, you may have made a mistake by saying some unkind words. If you make mistakes because you are tired, try to get more sleep; if you are stressed, look at ways to relax and keep away from the stress of work.
You should avoid feeling guilty about making mistakes, but at the same time, you should make a decision to learn from them. If you repeat the same mistakes, it shows you aren’t making progress and they cause repeating suffering. Often mistakes are caused by bad habits. To avoid making the same mistakes you need to break these bad habits. The sooner, the better.

FOOD is basic – it’s what keeps us going. But for students at the International Culinary (烹饪) Center (ICC) in New York City, it’s much more than that – food is the future. ICC “gave me a direction”, said Song Wenlong, 25, a Chinese native and recent graduate of the world famous cooking school.
ICC, which was set up in 1984, offers courses from chef (厨师)training programs to wine studies and restaurant management”, according to its website.
And as the school has grown, the number of international students to ICC, including Chinese, is rising every year. One example is Song Wenlong, who grew up in Shanghai but now works in Los Angeles as director of food development for RJ Chinese Kitchen, a restaurant in California.
Song has lived in the US for three years. He first completed a degree in Engineering at Stony Brook University in New York. Song said. “I chose the degree based on my parents’ opinion. The people I met abroad encouraged me to chase my dream, so I ended up changing my whole career path.”
That's what brought him to ICC ---his love of food. “Growing up, my uncle had a restaurant, and I loved going with him to the farmers’ market. When I was 16, I started to cook on my own.”
Song said he likes ICC’s ideas toward cooking. “They taught me how to cook, not special recipes(秘诀). They call it ‘cooking techniques’. I learned a lot from that. The two-month internship(实习) in a restaurant was helpful, too. It gave me a look at a high-quality, professional kitchen.”
Song highly recommends Chinese chefs and food lovers go abroad and study. Above all, he feels good about the fact that more young Chinese people are starting to chase their own dreams.

What is the main point of the article?
A. The popularity of cooking schools around the world.

B.It teaches students cooking techniques.
C.It has top professors from all over the world.
D.It lets students intern at the best restaurants.
