Have you ever had lucid（清醒的）dreams? Recent studies suggest that the number of people having them is on the rise. Someone having a lucid dream realizes they are dreaming and may from then on"direct" the action. Or they may simply "watch" the dream unfold.The sense of awareness（知道）makes it different from a dream that is simply very lively and true to life. And although the description may seem strange, the process is far from alien to many of us.
Studies suggest that the number of people in the Western world experiencing lucid dreams, which happen once in a while, has risen by between 10 and 40 per cent since the 1980s. Today, they are so common that about one in eight of us will have one in our lives. But still, little is known about what causes them or what is behind the rise.
Research carried out at the respected Harvard University in the US shows that the brain is working hard during lucid dreams. In fact，the level of the mental（精神的）activity in some parts of the brain is similar to that of a person who is awake. Lucid dreamers seem to share certain personal characters. For example, in general they are quite creative. They are also good at digging deep into problems and going out of their way to solve them. Furthermore,they always believe in personal responsibility rather than letting society carry the can.
Our nightmares（噩梦）may show our waking worries，with the five most common ones——falling, being run after, feeling disabled, being late and the death of a loved one.Men are more likely to have nightmares about fights or being fired while hair and tooth loss appear more in women's nightmares---perhaps showing worries about losing their looks. Research has also found that women have more nightmares than men. Their dreams are also scarier and more unforgettable.

【推荐1】We all know that smoking is bad for people’s health. But not many people know about the danger of second-hand smoke.
Second-hand smoke is the smoke that comes from the smoke breath (呼吸). If people breathe in second-hand smoke from time to time, they could get sick from it.
But how serious is the problem of the second-hand smoke? The World Health Organization (WHO) did a study of 194 countries. They found that second-hard smoke causes about 600,000 deaths every year. That is about 1% of the world’s deaths.
Second-hand smoke is especially bad for children because their bodies are still growing. According to the study, around 165,000 children under the age of 5 die each year because of second-hand smoke. Most of these deaths happen in Africa and southern Asia.
You can do something to keep yourself and other people away from second-hand smoke. You can ask the smokers, such as your parents, to smoke outside. And, if someone smokes close to you, you’d better hold your breath or just walk away.

As a result of years of study， we know that too much animal fat is bad for our health. For example， Americans eat a lot of meat and only a small amount of grains， fruit and vegetables. Because of the way they eat， they have a high rate (率) of cancer and heart disease. In Japan， people eat large amounts of grains and very little meat. The Japanese also have a very low rate of cancer and heart disease. The Japanese live longer than anyone else in the world. However， when Japanese people move to the US， the rate of heart disease and cancer goes up as their eating habit changes. And as hamburgers， ice creams and other high-fat foods become popular in Japan， the rate of heart disease and cancer is going up there as well. People are also eating more meat and dairy food in other countries， in which the disease rate is going up along with the change of the way people eat. Doctors everywhere suggest people eat more grains， fruit and vegetables and less meat and dairy food.
Eating healthily is important for children as well as their parents. When parents have poor eating habits， their children usually do， too. After all， children eat ‘ the same way as their parents. When parents eat healthy food， the children will learn to enjoy it， too. Then they will develop good eating habits. Doctors suggest parents give their children healthier food such as fruit， vegetables and juice.
Everyone wants to live a long， healthy life. We know that the food we eat affects us in different ways. For example， doctors believe that fruit and vegetables can really protect people from many different diseases. On the other hand， animal fat can cause diseases. We can change our eating habits now and enjoy many years of healthy living.

【推荐3】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. However, the real reason is probably that we don’t have enough sleep. Perhaps this is something you have not paid enough attention to.
Why do we need sleep? Sleep helps our body heal, grow, and stay healthy. It also gives us energy, so we can be active all day. Doctors and health scientists say when you close your eyes and need to rest, sleep is just the best! This is more than advice.
Enough sleep is important to us. How much sleep do we need? New-born babies sleep most of the time. They can sleep 20 to 22 hours a day. Children need 10 to 12 hours of sleep a day. Teenagers need 8 to 10 hours of sleep a day because they need lots of energy to grow into their adult bodies. Grown-ups usually need 6 to 8 hours of sleep to keep active.
Almost everyone has their dreams while they sleep, but not all of them can tell their dreams clearly when they wake up. Some people talk in their dreams. More surprisingly, some may even get up in their dreams and walk around. This is called “sleepwalking”. Are you a sleepwalker? Or, is there a sleepwalker around you?
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 (刺猬), sleep all through winter. The swift (雨燕) is a special bird that can sleep while it flies! Cute koalas sleep around 18 hours a day. Giraffes don’t need much sleep. They usually sleep standing up.

【推荐1】Do you have any experiences like these? When the teacher asks if anyone can speak in front of the class, you lower your head. When you go to the restroom or dining hall, you always try to find someone to go with you because you are afraid of being seen alone.
Well, many people have these kinds of experiences. They are feeling social anxiety (社交焦虑), or worrying about things like talking, going to a party or being the center of attention.
A recent study from China Youth Daily showed that about 45 percent of the 1,544 interviewers (受访者) said they experienced social anxiety.
Stefan Hofmann, an expert from Boston University, said that social anxiety is “a result of the fear that we will not be welcome”. For Chinese kids, there’s another reason for their anxiety. Shu Man from East China Jiaotong University said, “Most of them are the only child in their families, so they don’t have many chances to practice their social skills.”
“However, you don’t have to worry too much about social anxiety. You only need to ask the doctor for help if you can’t live a normal life,” said Li Songwei from Tsinghua University. Shu Man advised that you should go to public places more often, and try thinking about something happy when you are really nervous.

【推荐2】Recently children have been told to buy traditional alarm clocks instead of mobile phones to wake them up in the morning. Schools will advise pupils to turn off mobile phones or iPads in the evening to have enough sleep.
Researchers from a charity say that using internet-connected devices(装置)in the evening can prevent children getting more rest. Moreover, they suggest that school children should invest in a real alarm clock to make sure that they get a good night's sleep and arrive at school on time.
① . The result is that 40% pupils in secondary schools can now hardly get on well without these devices. About two-thirds of pupils have a habit of taking mobile phones to bed at night.
② . The study also shows that girls are more likely to be attracted by mobile phones than boys, and often use the Internet to talk to friends by social networking websites, such as Facebook and Twitter. One girl aged 12 said, "I have been told that I am addicted(上瘾的)to the Internet, and prefer being online to being with other people."
③ . A girl of 13 told researchers, "I can't imagine if someone takes my iPad away. I walk around the house with it even though its' not turned on. I just like being with it." Another girl added, "Sometimes I can't sleep without using the mobile phone at night."

At East China University of Science and Technology, students will get a coupon (优惠券) if they eat up their food. Students can collect coupons and exchange them for small gifts, such as books, magazines, mobile phone covers and hand warmers.
“It’s been such a surprise”, said Liang Zhaoyun, 19, a student at the university in Shanghai. “It has given us one more motivation to finish our food.”
The measure is part of a national “eat-up” campaign (运动) which is organized by students to deal with food waste on campuses.
Why only on campuses, you might ask? Because according to a report by Xinhua News Agency, students waste twice as much food as the national average.
The campaign on campus food waste is receiving attention across the country.
The aim of the campaign is not only to encourage students to finish their food. “We hope it can also encourage students to choose a more environment-friendly and healthy lifestyle,” said Tao Siliang, secretary (秘书) of the Youth League Committee at Shanghai University.
But some school food is poorly prepared, so students do not like to finish it all. Some schools have taken notice of this and they are taking measures to improve it.
“I’m glad that we’ve reduced food waste since the ‘cat-up’ campaign began. But if we call on students to waste less food, we should also improve the service and food standard on campuses.” said Tao.

【推荐1】①Does life sometimes seem to be full of impossible problems? How many times, for example, do you find yourself saying things like “I really don’t understand this Maths problem”, or “I can’t get into the school team”? Well, maybe it’s time to introduce yourself to the power of “yet”. By adding this simple word, you can change everything. “I really don’t understand this Maths problem yet.” “I can’t get into the school team yet.” Suddenly, the impossible becomes possible. You can imagine those things happening.
②I read about a school that has changed the way it marks its students’ exams. The school find out that the old pass/ fail system wasn’t helping students’ motivation(积极性). If you passed, then great, but those students who didn’t pass often felt like failures. So now students who don’t pass the exams will not see a big red F on their papers; they see a “Not yet” instead. That way the students feel that they are on a journey. They haven’t reached the end, but they know that they are going the right way.
③This kind of thinking is part of what experts call “having a growth mindset”. People with a growth mindset don’t concentrate on failure. They aren’t worried by not getting things right the first time and are happy to keep trying until they do. They enjoy the challenge and believe they can change. In contrast, people who just focus on the failure have what the experts call “a fixed mindset”. These people are always worried about failure and are happy to give up when things don’t go right. They don’t think that they are able to change. Clearly, it is better to have a growth mindset than a fixed mindset.
④But don’t worry if you think that you have a fixed mindset. ________. Remember that it all starts with questioning the things you believe about yourself. Stop believing that you can’t or you haven’t and realize that you just can’t or haven’t yet. Once you start doing this, you’ll wonder why you didn’t do it before. It’s one small but very powerful word.
1. The example in Paragraph 2 is to ________.| A．express a feeling | B．describe a problem | C．show the result | D．support the topic |
| A．Jack got an “A” in the exam. He was quite happy to tell his parents. |
| B．David failed in a competition, but he stays confident and keeps trying. |
| C．Jenny found it hard to work out the maths problem, so she gave it up. |
| D．Emma was refused by school team. She didn’t want to have another try. |
| A．Experts will help you grow up healthily in mind |

【推荐2】Chinese people have been celebrating the Spring Festival and enjoying dumplings for centuries. Dumplings are always a kind of popular food in Northern China and are often found on the table during the Spring Festival. Dumplings are in the shape of Yuanbao. They carry people’s wishes to the New Year. Eating dumplings during the Spring Festival means “Bring in health and treasure”. Dumplings are also a symbol of home and warmth.
There are many legends (传说) about the origin (起源) of dumplings, but no one knows who invented dumplings exactly. Nowadays, many agree that dumplings were first created by medical Saint Zhang Zhongjing in the Eastern Han Dynasty. At that time, dumplings were used for medicine.

China’s love for winter sports has been growing. The Ministry of Education has set a goal of building 5,000 special schools by 2025 to improve winter sports education.
The government has also been encouraging primary and middle schools to add winter sports to their subjects. Many provinces and cities have already acted on this suggestion. Classes will be set up in schools in northern China to improve interest in winter sports. In southern China, schools can work with ice rinks（溜冰场）and winter sports clubs.

【推荐1】Once upon a time, a wealthy villager hid a huge piece of gold in a nearby rice field to protect it from thieves.
Many years later, the wealthy man died and no one else knew about the gold. One day, a poor farmer began to plough (犁) the field. After ploughing for some time, his plough struck the long forgotten treasure.
At first, he thought it must be a very hard tree root. However, when he went closer to look, he saw that it was a large piece of beautiful shining gold.
Waiting until midnight, the farmer started to take the gold home. He tried to lift the gold but it was too heavy. He tried to pull it out with ropes, but it was so huge that he could hardly move it. He became frustrated and thought how lucky he was to have found treasure, but unlucky too, as he could not move it. He even tried kicking the gold but it would not budge!
He sat down and began to use his head. He decided to break the gold into smaller pieces. This would enable him to carry the gold easily.
He thought to himself, “I will use one part for my daily needs and I will save the second part for a rainy day. I will invest the third part in my farming business. I will use the fourth part to help the poor and needy.”
Follow this, he calmly divided the huge piece of gold into smaller pieces. Finally, he took all the gold home easily and lived happily ever after.

【推荐2】Since July 2019, Shanghai has been the first city to sort their garbage. Starting on May 1st, 2020, Beijing also became one of the members by introducing a new garbage sorting policy. Green garbage has come to China.
In the past, people put a lot of garbage into one pile and then took the garbage to landfill sites. These landfill sites, however, could pollute the land and water. So, if we can find ways to reuse or recycle more garbage, then we will cause less pollution.
The new plan asks people to put their garbage into four different boxes, one for each type of garbage. The brown box is for “wet garbage” (such as food and drink waste). The red one is for harmful waste (such as batteries and electronics). The blue one is for recyclable things (such as paper and plastic). And finally, the black one is for “dry garbage” (everything else). This “sort your garbage” plan is the same as other plans used by cities around the world. These plans have been very successful. In Canada, it's expected that 85 %of plastic will be recycled by 2025.
Why should we sort our garbage? The reason is that we are producing increasing amount of waste every year. It's reported that Chinese cities produce over 200 million tons of waste each year. Reducing that amount will surely help the environment.
However, the garbage sorting is a long journey as it takes time for people to learn and form a habit. More cities are on their way. By 2025, it's hoped most Chinese cities will complete the building of garbage sorting.
