Beautysleep is a real thing, researches have shown that people who have enough sleeplook more attractive (有魅力的) to others.

    A few badnights are enough to make a person look especially "more ugly", theirsleep experiments show.

    Theresearchers asked 25 university students to join in their sleep experiment.They were asked to get a good night's sleep for two nights.

    A weeklater, they were asked to sleep for only four hour every night for two nightsin a row. The researchers took make—up free (素颜) photos of the volunteers afterboth the good and the bad sleep.

    Next, theyasked 122 strangers to have a look at the photos and judge (评价) them on attractiveness, health,and sleepiness, as well as asking them: "How much would you like to makefriends with this person in the picture?"

    Thestrangers were good at judging whether the person they were looking at wastired, and if he was sleepy, his attractiveness score would be low.

    Thestrangers also said they wouldn't want tosocialize with the tiredstudents. The researchers say this is natural for people. An unhealthy-lookingface makes people run away. In other words, people don't want to hang aroundwith people who might be ill.

    Dr Brewer,an expert at the University of Liverpool said: "Judgment of attractivenessis often unconscious (无意识的), but we all do it, and we are able to judge on even somethingsmall like whether someone looks tired or unhealthy. This study is a goodreminder of how important sleep is to us."

At 9:30, Rose said, "I hate going to bed. I want to stay up and watch a show!" At 6:00 in the morning, her alarm clock went off. Her mother heard her say, "The only thing I hate more than going to bed is getting up in the morning!"

What does Rose have in common with thousands of kids? She is not getting enough sleep. Have you ever stayed up later than you should? If you have, you know that not getting enough sleep can leave you feeling tired and upset. You may have even noticed that it's hard to think clearly and stay focused (专注的) when you are overtired.

Need some motivation (动机) to go to bed on time? Here are some important advantages (好处) of getting a good night's sleep. After a good night's sleep, we are more energetic, smarter and even happier.

Do you like to play sports? It has been shown that football players, swimmers and tennis players all perform better after a good night's sleep. Your coach may not tell you this, but the simplest way to improve your performance is to get enough rest.

Do you want to improve your grade? Healthy sleep habits improve your memory and your ability to pay attention to tasks, making schoolwork seem easier. While you get a snooze, your mind is very busy so you needn't get a good rest like a long sleep. Researchers have found that it's easier to learn after a good night's rest. So, it's no surprise that students who get enough sleep get better grades than those who don't.

Science and experience have shown that getting a good night's sleep is the key to success in whatever you do. Get a good night's sleep. You're worth it.

Lake Tahoe is the best place to go during winter vacations. You will have a lot of fun if you follow these tips(提示).

The first thing you should do is to wear at least(层) three layers(层) clothes. If you don't, you will have a cold!

You should also go skiing(滑雪) for at least one day. If you don't, your trip to Lake Tahoe will be boring.

Stay there for at least three days and two nights. If you don't, you won't enjoy yourself there. You may spend a lot of time on the way. It will be a waste of time and money.

Also, here are some things you shouldn't do at Lake Tahoe.

First, don't drive on the highway when it's snowing, or a traffic jam(交通堵塞) will make you angry. Second, don't try the sk i resort(度假村) food. Believe me , it's terrible. Bring your own food. At last, be careful when you sk i by yourself. Skiing is a dangerous sport. When you are skiing, you may fall down, get hurt or even die.
