Like schools in China, American schools begin in September after a long summer vacation. There are two terms in a school year. The first term is from September to January and the second is from February to June. Usually American children begin to go to school when they are five years old. Most students are seventeen or eighteen years old when they finish high school.
But unlike middle school students in China, high school students in America take only four or five subjects each term. They usually go to the same classes every day and have homework for every class. After class they do all kinds of interesting things.
After high school, many students go to college. They may go to a small or a large one. They usually have to pay a lot for their higher education. So lots of students work after school to make money for their studies.

At 18, many American young people go off on their own. They go away to college or find full-time jobs, and they often rent their own apartments. Some get married and start families. This independence(独立性)is learned from childhood. From an early age, American children learn responsibility. Children as young as 2 begin to put away their toys and dress themselves. At 3, many children do simple chores like setting the table.
Using money wisely is also taught early. As soon as a child understands the value of money, he or she receives a weekly allowance. This is used for things the child wants, like toys or treats. The child can spend of save it, usually with little guidance(指导) from parents. If the child wants money besides his or her allowance, it must be made by doing extra chores.
Children are taught early in life to think for themselves. They are allowed to make some decisions-and make mistakes. Failure(失败) often teaches more than success.

A young girl called Ida in Sweden decided to travel to a place she hadn't seen for 22 years. She had a happy life until some kids asked, "Why don't you look like your mom?" Ida was sent to her adopted(收养) family in Sweden right after she was born.She really didn't know anything about her birthplace, Korea, except for some information she recently heard about her birthparents.
During her schooldays, she was often questioned about her looks. Ida considered herself a normal Swedish person. She tried to be part of the group in her school, but she found it hard. She was still seen as an outsider.
As she grew older, she accepted(接受)who she  was. Still, she
wanted to find the missing piece of the puzzle (困惑). After finding out the place of her birthparents, Ida went to Korea in 2008. When she first arrived, she was surprised to see so many people who looked like her. However, apart from her looks, not much could be shared (分享) with others. She knew little about the culture, food, especially the language. Being in Korea wasn't always easy for her.
Perhaps Ida can never truly fit in either culture, but it's worth visiting her birthplace because she finally realized how special and different she is. She has two loving families, and most of all a better understanding of who she is. This helps her to have a positive view of her life.
【小题1】 Where was Ida born?

A．In Japan.

B．In Sweden.

C．In England.

D．In Korea.

【小题2】Why was she seen as an outsider in Sweden?

C．Because of the food.	D．Because of the language.

C．Ida still couldn't accept who she was after she went back to Sweden.

D．Ida realized she can't live a happy life either in Sweden or in Korea.

After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered an Earth-sized planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid（液态）water. Scientists think there is a chance that the planet could have life.
The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth. That is about 194 trillion（万亿）kilometres －500 million times farther away from us than the moon.
A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years. A human can’t live that long, but robotic explorers could make the job easier. However, our fastest spacecraft don’t come anywhere near that one-tenth light-speed mark.
At present, scientists don’t know what the surface might be like on Gliese 581g. What they know is that the planet is at the sight distance from its star to have liquid water. It’s also at the right distance to have an atmosphere that could protect the water if it is on the surface.
Although spacecraft won’t be getting there anytime soon, one way to look for life on Gliese 581g is to turn our radio telescopes（望远镜）towards the planet and search for radiation（放射）. By studying the radiation, scientists would find out about the chemicals（化学物质）around the planet and discover it Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea if the planet has life or not. But it’ll probably be many years before we can do this properly.
People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life is just guessing at this point, according to its discoverers.
【小题1】 What did scientists find in September 2010?

A．A planet with water.	B．A planet similar to the earth.
C．A planet without life.	D．A planet near the earth.

【小题2】According to the article, Gliese 581g ________.

A．is at the right distance from its star	B．moves around the earth
C．is as far away from us as the moon	D．can be reached in about 220 years

【小题3】 Paragraph 5 is mainly about ______.

A．the possibility of living on Gliese 581g

B．the kinds of chemicals around Gliese 581g

C．the way of looking for life on Gliese 581g

D．the aim of studying the radiation on Gliese 581g

【小题4】Which of the following is the best title for the passage above?

A．Gliese 581g, a Likely Living Planet	B．Gliese 581, a Likely Living Planet
C．Gliese 581g and Its Star	D．Gliese 581g and Radiation
