Spending two or three hours playing outdoors each day can reduce the chance of becoming short-sighted, 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 compared 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. |
It’s so beautiful outside that spending the day in the office would be very boring. So why not take the vacations(假期)off?

阅读下面短文，简要回答所给问题。
It was near Christmas during my first semester teaching at a new school.I loved my small special class more than any group I had taught in the past.They were hungry for knowledge and I was enjoying teaching.
Other teachers had told me that our children were from poor families and not to expect any child to bring a Christmas gift.In fact，I wasn't expecting any gifts.
Imagine my surprise when every child brought me a gift on the day before our holiday break.First，I got a muchloved stuffed monkey from a shy girl.I was told，“He is my favorite，but I love you and I want him to be with you，Miss Taylor.”How thrilled I was!
Next came a new set of Christmas tree lights that was “missing” from a mother's cupboard.
Finally，I came to one little boy's gift which I had never received.It was an old，dirty and broken Christmas story book.Just when I wanted to express my happiness，I was interrupted(打断)by the giver，“And see，it is new！It still has the price tag.”
When other children laughed at him，I stopped them and said，“Oh，books are good in that way.The story is always new if you have not read it before.Now，let's share one together.”Everyone listened quietly as I read the most wonderful Christmas story of my life.
I still keep those Christmas gifts.They always remind me of my lovely kids.

Dear Owner, please listen to me,
My life is likely to last ten to fifteen years. Any separation(分离) from you will make me sad. Remember that before you buy me.
Give me time to understand what you want of me.
Don't be angry with me for long and don’t lock me up as a punishment. You have your work, your entertainment and your friends. I have only you.
Don’t forget to feed me. I’ll be happy if you give me my favorite food--bones.
Talk to me sometimes. Even if I don't understand your words, I understand your voice when you’re speaking to me.
Take care of me when I get old. You, too, will grow old.
Go with me or difficult journeys. Everything is easier for me if you are there. Remember, I love you.
