World Sleep Day is March 21.Many experts have held a press conference (新闻发布会) in Beijing Hotel.Sleep is sometimes called “the cousin of death”.But funnily enough, it is also one of the most important things we need to stay alive.People spend almost a third of their lives doing one things: sleeping.Sleep is like food for the brain.Enough sleep helps the body and brain grow and develop.

People of different ages need different amounts (数量) of sleep.According to the National Sleep Foundation in the US, adults need seven to nine hours of sleep every night.For students aged 10 to 17, a healthy amount is about eight to nine hours per night.

To solve this problem, scientists advise that students should get less schoolwork and more time to sleep.There are some other ways to help people get enough sleep, such as taking a 20-minutes nap (小睡) during the day.Good sleep habits are also helpful.For example, try to go to sleep and wake up at the same time every day, even on weekends and during holidays.

According to a recent report, kids in primary school spend about six hours every week doing their homework.. So kids hate homework. However, their parents hate homework, too.

Is it good for kids to do homework? Of course, a great number of researches do show that kids can remember what they have learnt in class better by finishing their homework on time and homework itself plays an important role in developing their learning shills, such as independent thinking and creativity.

But for parents, the result is not the same. After a day of hard work, most of them feel like they’re going through school a second time when they sit down with their children each night to help with their homework. And a recent survey found that 46 percent of parents feel like they don’t spend enough quality time with their children, because they spend too much time doing the housework or helping with homework. And another 29 percent of parents have arguments with their kids often when they have different answers to the same question.

Now several education scientists strongly advise parents to stop helping. They say it will give their kids more independence and give parents back their free time. At the same time, the number of homework – connected arguments will be less at home. Katy Smith, an education scientist, says, “ You don’t have to know everything. Children need to put their hands up for help and so do parents. Use your resources – online teachers, or even your neighborhood – just ask.”
