Do you know the reason why we feel tired in the middle of a class? Maybe you would say it is because the teacher’s class is boring.
Purpose of sleep.
Sleep time.
Enough sleep is important to us. How much sleep do we need? New-born babies sleep most of the time. They can sleep 20—22 hours a day. Children need 10—12 hours of sleep a day. Teenagers need 8-10 hours of sleep a day because they need lots of energy to grow into their adult (成人的) bodies. Grown-ups usually need 6-8 hours of sleep to keep active.
Interesting facts.
Almost everyone has their dreams while they sleep, but not all of them can tell their dreams clearly when they wake up.
It’s not just people that love to snooze (打盹). In fact, many animals have unusual or surprising sleeping habits. Some animals, such as bears and hedgehogs, sleep all through winter. The swift is a very fast bird that can sleep while it flies! Cute koalas sleep around 18 hours a day. Giraffes don’t need much sleep at all. They usually sleep standing up.

【推荐1】Now too much CO2 makes the Earth warmer and warmer, and brings bad effect to people. To save our Earth, a new lifestyle called low-carbon life becomes popular. Low carbon means low energy and no waste. It is necessary for everybody to learn to live a low-carbon life.
To live a low-carbon life, we’d better save as much energy as we can. For example, turn off the lights and TV when you don’t use them, use cold water to wash clothes or dishes; take a short shower and try to take a cold one when the weather gets warm; don’t do the cooking with electricity.
To live a low-carbon life, we should eat less meat. Being a vegetarian can help reduce(减少) one and a half ton of carbon dioxide a year, but keeping animals for food produces even more carbon dioxide than all the cars do in the world.
To live a low-carbon life, we should plant more trees. Trees are very important for us. They can not only produce oxygen for us to breathe and keep the air clean, but also take in the harmful gases from the air. To protect trees we should stop people from cuting down trees and plant as many trees as we can.
If we can keep them a habit in our daily life, the earth will become a safer planet for us to live on.

【推荐2】Have you ever been shopping and thought you were getting a good deal simply because the price appeared in red? Or have you left a shop because the salesman talked too much? If your answers are yes, you’re not alone. In fact, your actions are typical (典型的).
We find, quite interestingly, men are more affected than women. When men see an advertisement with the prices written in red, they believe the shop is offering better prices than those written in black. They feel sure about buying the products as well.
However, women don’t feel the same way. When it comes to shopping, women think about everything much more carefully than men. Experts explain that if women see the prices in red, they will question what’s happening and think they must be more careful. “Am I being tricked?” they’ll ask themselves. Women also seem to have a much better memory than men when it comes to the prices in an advertisement, because men are not interested like women.
A new study shows that the key to a successful sale is reading customers’ moods and matching them. The experts explain that if a customer is angry, in a hurry, or in a bad mood, he’d like to deal with a salesman who can understand him, serve him quickly, or just leave him alone.
There are, of course, some other factors (因素) in making a sale. For example, good weather means good news for shop owners. About 60%—80% of customers’ decisions are made while people are actually in a shop. And as more people are out during nice weather, there’s a higher chance when they’re shopping.

【推荐3】Humans and gorillas(大猩猩) shared evolution(进化)for 23 million years. Their paths separated only six million years ago. New research on how gorillas communicate may help us better understand human language.
Understanding how the brain works helps us see a connection (联系) between language development and non- verbal(不使用语言的) signs. “Gorillas have many kinds of non-verbal communication.” said psychologist(心理学家) Sebestyen Forrester from the University of Sussex. He thinks humans may have had the same communication skills.
Non-verbal communication includes the ways we move our bodies and the different expressions on our faces. A new study on gorillas showed that right-handedness may have a connection with communication. The right side of the body is controlled by the left part of the brain, which is also where language develops.
Two cameras were used to watch how one gorilla moved. It was shown that gorillas use their right hands more when they are doing actions with their heads or mouths at the same time. This may show that there is a connection between how our brains work and the reason we use one side of our body more than the other.
Forrester said the results could help us understand how children learn languages. For example, some children have a condition called autism (自闭症) in which they have a hard time communicating with other people. This same kind of study may help doctors find autism in children at an earlier age.

【推荐1】During the winter months, it is comfortable to stay inside in the warmth and read a book or watch TV. However, winter is one of the best times of year to go for a walk outdoors and experience the joys of nature, embracing (适应) the colder weather and fresh air can be good for you. Liz Nelstrop at the National Trust tells us, “Coming outside in the winter months is just as exciting as it is during the other seasons, and it is good for mental and physical happiness.”
Several studies have shown that spending time in nature can be good for people’s health and happiness. One study from 2019 showed that spending at least two hours a week in nature could have a positive effect. Being outdoors means being active and this is good for your health. Walking in fresh air and spending time in nature can be relaxing and makes people feel calmer and less worried. It is also a time to put away computers and phones and forget about homework. It’s a great way to spend time with family and friends.
“Winter is the perfect time for exploring,” Nelstrop says. “The trails (山径) are usually quieter and the lack of leaves on the trees can mean some views are even more unforgettable than usual.” Walking in colder weather is often refreshing and makes you feel good. There is a saying, “There is no such thing as bad weather, just bad clothes”, which means that as long as you have suitable clothes, you can face the colder weather. However, if it is terribly cold, raining hard or there are strong winds, wait for better weather before out for a walk.
There are lots of great places to go walking wherever you are. There are coastal paths, woods, trails in the countryside, as well as parks and other green spaces in cities.
