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."

Hello, everyone! My name is Liu Wei. I am 12 years old. I was born in Nanjing. I am a friendly and honest (诚实的) boy. I have a happy family. There are four people in my family—my father, my mother, my sister and me.

My father looks strong. He is a doctor in a hospital near my home. He is so busy that he has no time to play with me. But I know he loves me. He likes running, swimming and playing basketball. 

My mother is tall and slim. Her hair is long and black. She has many hobbies. She is good at planting vegetables and flowers. She also enjoys traveling with me. My mother does a lot for me. She always looks after me well. And she is very strict (严格的) about my study.

My sister is 13 years old. Her name is Liu Li. She has big eyes. She looks cute. In her free time, she likes reading, dancing and listening to music. We study in the same school. She is good at all her lessons. She wants to be a Chinese teacher when she grows up.

I love my family very much. I hope all my family members always stay happy and healthy.

 In small towns, people are used to saying hello to their neighbors in stores, on the streets and in front of their homes. In today's city life, people may feel uncomfortable talking to neighbors they do not know well in line at the supermarket. But greeting your neighbors is actually good for you, especially if you say hello to six people, according to a recent survey.

 Saying hello to people increases well- being(幸福), but six is the magic number. The well- being score increases from zero to six and then there are no further increases. These results are part of the Gallup National Health and Well- Being Index which studies overall well- being and is calculated on a scale of (在……范围内)0 to 100. The survey was carried out from May 30th to June 6th, 2023 and was based on the answers from 4,556 Americans. It covered social well- being, physical well- being, community well- being and more. People who said they didn't say hello to anyone in their neighborhood scored a 51.5. People who greeted six neighbors had a score of 64.1.

 You might think that saying hello to neighbors is only about social well- being, but that actually isn't the case. In fact, regular(经常的) greetings also improve a person's physical well- being and community well-being.      ▲      You will be more likely to speak to people if you think your community is safe. Your physical well- being can improve if you are getting out and walking around your neighborhood.

" We don't require that you know the person well; just stop and talk to him," said Dan Witters, the survey's director." But the more people to whom you say hello, the greater the probability is that you' re actually going to start a conversation with them."

 While this is just a survey for now, saying hello on a regular basis is a good way to improve your own well- being.
