阅读理解（三）　 健康生活
A　［2019·天津]
  There are many ways to help improve your health like eating healthy food, taking exercise and getting medical help。 But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night. The general sleeping rule is that the younger you are, the longer sleep you need。 But regardless of（不管) age， some people need to sleep more while for some a few hours is enough.
less is more英文理解The problem with sleep is that more and more people in the world are not sleeping enough. According to the World Health Organization, over half the people in the world may be sleep—deprived。 Having less sleep not only makes people feel tired but also causes accidents。 In the United States alone, sleepy drivers cause at least 100,000 traffic accidents a year. Also sleep problems can cause medical problems such as high blood pressure（血压).
Why are so many people sleep-deprived? Part of the reasons may be cultural。 In the American culture， people put a higher value on work than on sleep。 In fact， people who sleep a lot are usually seen as “lazy"。 Also, you can sometimes hear some people say proudly that they don’t have much time to sleep， they only sleep four or five hours a night. It seems that the less you sleep， the more work you'll do.
How do we teach these people to learn the value of sleep？ Perhaps they may listen to the advice of Dr。 James Maas, an expert(专家） in sleep. He says， “Sleep is like a credit（信用） card. When you sleep less, you are only borrowing time. You always have to pay it back. The more hours you don’t sleep, the more hours you should sleep to ‘pay back’ the hours on your ‘sleep credit card’."
For those who value work more than sleep, they should listen to what a famous person once said， “Don't think you will be doing less work because you sleep during the night。 That is a foolish（愚蠢的) idea which is held by people who have no imagination。 You will be able to do more."

As we all know， exercise is an important part of a healthy lifestyle。 You will get better fitness with stronger bones and muscles。 It will stop you putting on weight and you’ll feel happy that you have done something good。 It’s also a chance to meet up with friends or make new ones。 However, not everyone likes doing exercise or playing sports。 Here are some excuses young people use when they don't want to exercise：
“None of my friends or family does it。”So be different。 They might be encouraged by your example and join in themselves.
“It's a boy's thing。" It’s true that more boys than girls take exercise， but that’s not because girls are rubbish at sport。 Many girls try activities outside school.
“I don’t want muscles.”Being fat and having big muscles don’t necessarily go together。 To get big muscles， you should have to do a programme of special exercise。
“It's sweaty。”
“I’m overweight."
“I don’t like joining teams."
“I'd rather play with the computer。” It doesn’t have to be either. You can do both.
“It’s not cool。” Try telling David Beckham this? All right, we can’t all reach the very top, but we can benefit from being fitter. People who tell you it’s not cool are usually the ones that couldn't run to catch a bus when their lives depended on it.
But don't you think it’s time to stop making excuses and start doing something fun and healthy? Taking exercise is fun—really. Just give it a try。
1。Which is not the reason for “exercise is an important part of a healthy lifestyle”?(  ）
A.Exercise can make you get better fitness with stronger bones and muscles.
B。Exercise can stop you to put on weight.
