When you're closing your eyes and hitting your pillow, you're probably not giving much thought about the sleeping position throughout the night. Most people don't change their sleeping positions throughout their lives. The following is why you might want to pay more attention: Your sleeping position can actually say a bit about who you are and what your personality is like.

    There are many sleeping positions. The fetal (胎儿的) sleeping position is generally the most common sleeping position. Fetal sleepers sleep on their side, they move into a position in which their body makes a rounded shape. People who sleep in the fetal position are often quite sensitive and generally shy. They are often worried or nervous and don't focus their attention on the main problem, but get into trouble on very small pieces of information.

    The log (木头) sleeper rests on the side with a straight body when hands and legs are kept at the sides. These sleepers are often relaxed, but also can easily believe lie-tellers. If you're a log sleeper, you might want to keep in mind that it's good to be easy-going and have less stress, but don't be so quick to go with the flow (流) at all times.

    The third one is the soldier position. Soldier sleepers typically lie on their backs with both arms close to their sides. In general, they are the strong and silent type. However, they can also put the pressure on. "They can be quite strict with themselves as well as others," a scientist added.

    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."

Health problems which are related to climate change are getting worse, say two research reports.

The report s followed 44 health problems that are related to climate change around the world. They include heat deaths, infectious diseases（传染病）and hunger. "All of them are getting worse," said Marina Remanello. She is research director of the Lancet Countdown project. "With global worming getting worse, doing nothing on climate and health will cost more than acting now, one of the reports says.

The reports are called "code red for a healthy future". One report is centred（集中）on the US and the other is centred on the whole world. The reports found some dangerous facts. At-risk populations like older people and the very young are more easily influenced by high temperatures. For people over 65, the researchers found they stayed living in warm places where it is easier for some diseases to spread. For example, coast areas are warm enough for dangerous bacteria （细菌）to grow. In some poor nations me season for disease-spreading mosquitoes（蚊子）has got longer since the 1950s.

The research also found that 72 percent of countries saw an increase in wildfires. And in 2020, up to 10 percent of the world's land surface was influenced by extreme（极端的）drought. In the US, the heat. fire and drought caused the biggest problems. The Pacific Northwest and Canada saw extreme neatwaves. An earlier study found that the heatwaves would not have happened if there were no human-caused climate change.

There are several different kinds of sea turtles in the world. The sea turtles are endangered. Several are in danger of being gone {#blank#}1{#/blank#} ( complete).

Sea turtles lay large groups of eggs under the sand on beaches. The eggs face many challenges, both natural and man- made. In Costa Rica, one big challenge is poachers(偷猎者)— they take the eggs in order to sell {#blank#}2{#/blank#} ( they).

Kim Williams Guillen is {#blank#}3{#/blank#} scientist. She works for the University of Michigan and Paso Pacifico. She works {#blank#}4{#/blank#} ( protect) animals in Costa Rica. AfterKim{#blank#}5{#/blank#}( watch) some TV shows, she suddenly had an idea. What if poachers could be followed by using a fake(假的) t urtle egg {#blank#}6{#/blank#}a GPS tracker(跟踪器) inside?

Dr. Williams Guillen showed that idea and it won a $10,000 prize. She then worked with other scientists to create the fake egg. It was made of a special material, just like a ping- pong ball.{#blank#}7{#/blank#} it was cheap and easy to make fake eggs, they made a lot of them.

The scientists put some fake eggs into 101 {#blank#}8{#/blank#} ( difference) t urtle nests in Costa Rica. According to the results, most eggs {#blank#}9{#/blank#} ( sell) to local people. That wasn't a big surprise, since in Costa Rica, turtle eggs are considered a special kind of food.

The scientists are excited about the results of the fake eggs. The test shows that such simple ways can work well. The scientists believe that similar ideas could be helpful in other{#blank#}10{#/blank#}( place) as well.

 Pandas are in danger. There are only about1, 600 pandas in the wild today. Zoos and research centers are looking after about 340 pandas. Pandas do not have many babies, and baby pandas often die. The situation is getting very difficult. Scientists are doing a lot of research to help pandas produce more babies and help baby pandas live. 

 Pandas live in the forests and mountains of Southwest China. Each panda needs to eat a lot of bamboo every day. The bamboo forests are getting smaller, so pandas are losing their home. 

 In order to protect pandas in the wild, the government is setting up nature parks and developing other plans. The nature parks will be big and there will be more bamboo to feed the pandas. Pandas born in zoos may go back to live in the nature parks. 

 The World Wide Fund for Nature(WWF) wants to protect all animals. And it chose the panda to be its symbol. We do not want to lose tigers, elephants or any other animals, so the WWF is working hard to save them all.
