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.
【小题1】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.
【小题2】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.
【小题3】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.

In almost every big university in the USA, football is a favorite sport. American football is not like soccer. Players sometimes kick the ball, but they also throw the ball and run with it. They try to take it to the other end of the field. They have four chances to move the ball ten yards. They can carry it or throw it. If they move it to the end of the field, they will win six points. This is called a touchdown.
It is difficult to move the ball. Eleven men on the team try to stop the man with the ball. If the man does not move the ball ten yards, his team kicks the ball to the other team.
Each university wants its team to win. Thousands of people come to watch. They all yell(大喊) for their favorite team. Young men and women from the cheer team dance and jump while they yell.
Each team plays ten or eleven games each season. The season begins in September and ends in November. If a team is very good, it may play another game after the season ends. The best team plays again on January 1st, the first day of the New Year. Many people go to see these games and many others watch them on television.
