A good night’s sleep in the early years of life could be very important in preventing a child becoming obese, say scientists. Babies and pre-school children who sleep for less than ten hours a night are more likely to be overweight when they are older, research has found. Experts believe that those who do not get enough sleep are more likely to feel hungry and want more calorie-rich food during the day.

Former research has linked sleeping with obesity in adults and teenagers, but this is one of the first to look at very young children. Researchers from the Universities of Washington and California looked at the sleeping habits of almost 1,000 children under the age of five. They found those who had less than ten hours’ sleep were twice as likely to be overweight five years later.

Childhood obesity has doubled over the past 10 years. A quarter of secondary school pupils are now judged to be so overweight that their health is in danger. Experts believe sleep, or lack(缺乏)of it, could be a major cause of this. On average children are sleeping for an hour less than they did 30 years ago. Last year Chinese researchers looked at more than 5,000 youngsters and found that those who were able to catch up on (补充)sleep at the weekend were far less likely to get body weight problems. Scientists have also found a link between lack of sleep and diabetes(糖尿病). Last year Canadian researchers discovered those who did not get seven or eight hours’ sleep a night were two and a half times more likely to become sick.

A.too little sleep will result in illness besides obesity

B.in the past people didn’t connect sleep with weight

C.fat children must have slept less than 10 hours five years ago

  I have been working since I was thirteen, and always in   4   in which I was working with adults.I have had to learn to think and   5   like an adult to be taken seriously.So, I count myself as one who has grown up too fast.I just graduated from high school, and have recently spent some time reflecting(反思)on the   6   eighteen years-thinking about myself, what I have gained, and what   7   I have yet to achieve.

  We are expected to work hard, get excellent   8  , be in a good relationship, and know what we want to do   9  .The list goes on and on.But the   10   is clear:We live in a society today that is   11   our childhood.We no longer have many years to be careless and fancy-free.We are expected to   12   the strict school rules and to excel(擅长)in everything we do.I’ve known these things for a long time, and knew that they   13   me.But, I never really admitted it until last night, when I learned a   14   lesson, taught to me by my boss where I work.We had finished a job at a remote site.It was about 11∶30 at nig-ht, and we had   15   to his house.We were talking about the   16   he had been making to his home.One of the things he said was “I   17   my basketball hoop(篮圈).” Then he threw a basketball to me.

  I hadn’t   18   a basketball in five years.

  We proceeded to shoot hoops for about 40 minutes.Both of us were terribly bad at it, but we spent the whole time   19   away like children.Then I realized something:I am still a child.Oh, the law says I’m an adult.But, we are still really and truly children.We all need to have   20   once in a while.
