But there are some simple rules that you should follow about taking a nap.You should take a nap at noon,about eight hours after you wake up.In general,a 20-minute nap is the best.If you sleep longer,you may fall into a deep sleep.After waking up,you'll feel worse.Also,you may set an alarm clock.That way,you can feel fully relaxed during the nap.You don't have to keep looking at the clock so that you don't oversleep(睡过头).

Each year,many Chinese people go abroad because of all kinds of reasons.They are becoming younger and younger year by year.Even some Chinese parents send their children to foreign countries when they are only in a middle school.They think their children can get a wider view,less academic(学业)competition or family honor.But life can be hard for young people there.At first,they have to face the culture differences and language problems.However,these are not always the most difficult things to overcome(克服).To most children,controlling(管理)themselves well is a big challenge when studying alone in a strange country.

Yu Yang,a 15-year-old student from Guangdong Province studies in a high school in Toronto,Canada.To his surprise,his teachers there seldom push students to study hard.And usually there isn't too much homework.Students have lots of free time to do some activities.Some of his friends spend their whole year's money in the first two months of the new term.So they have to ask their parents for some more money.

On the one hand,studying abroad can help students learn foreign languages quickly and open up their eyes,but on the other hand,some children may feel lonely,become bad,lose themselves,etc.Many problems may happen to them.These are different from their original thoughts.So parents should think them over before their children go abroad.

Answer the questions according to the passage.

1.Why do Chinese parents send their children abroad?

2.What do the students have to face in foreign countries at first?

3.Controlling themselves well is a big challenge,isn't it?

4.Do students in Canada have more free time than those in China?

5.What’s the article mainly about?
