What is the most stressful thing in school? It is probably exams.Exams can put us under a lot of pressure.But some students do well under pressure，while others feel terrible.So，why do some students perform better under stress?

It all comes down to dopamine(多巴胺)．Dopamine is a chemical(化学物质) in our brain that sends signals(信号) to our body.It has many important roles：influencing memory，attention and how we learn.Our brains work best when there is a balance of dopamine — not too much or too little.

大脑通过两种方式控制多巴胺。It either takes out dopamine quickly，or gradually.Exam success can be connected to how fast dopamine goes back to a balance.

What happens when we take an exam? If you become stressed，your brain will start to overload(超负荷) on dopamine.It is like a cup overflowing with water.The quicker you can go back to a balance of dopamine，the quicker you will concentrate，helping you perform better on a test.

Scientists found that，during a test，people who slowly got back to a balance of dopamine scored 8 percent lower.That's the difference between a good mark and a bad mark.

But don't fear，there is some good news.The__study__also__found__that__the__more__practice__you__get，the__less__stressed__you'll__be.So，it turns out that practice really does make perfect.

Paper or plastic?

After paper, plastic seems to be the most popular material for making banknotes. Compared with paper money, plastic banknotes are stronger and last for a longer time, so people can keep using them. But they are much more expensive to make.

The fifth edition of the Renminbi (RMB) came out on Aug. 30, 2019. These bills will have brighter colors and new security features, which will make printing fake（假的）money even harder. We've been using banknotes for around 1, 000 years. Back in the Northern Song Dynasty, Chinese people made the world's earliest paper money to replace metal coins（金属硬币）. These banknotes were called jiaozi.

Obviously, paper money is cheaper to make and easier to carry. These advantages made it more popular than other forms of money. But now, in the digital（数码的）age, paper money seems to be disappearing for the same reason-what's more convenient than not having to carry any money at all?

My life in Beijing is quite different from that in India. 在中国, 我出去的时候很少带钱。I can pay for almost everything by Alipay. It's amazing. However, if you don't take wallet with you, you'll get into trouble.

　　　　　　　　　　　　　 -Sam from India

China seems to be heading toward becoming a cashless society. From supermarkets to street stalls（小摊）, people pay by using the WeChat Wallet and Alipay apps on their mobile phones. Sweden is even closer to a future without paper money. Many Swedish banks no longer even have cash on hand.

But there are worries about creating cashless societies. Some say, "It's unfair to the poor and people without too much education.”It's not easy for them to open bank accounts（账户）or deal with mobile phones. And if all of your money is digital, you may lose your money if your accounts are hacked（黑客攻击）.

Although paper money is in a losing war with electronic payment in some countries, it's still a big thing in most parts of the world. It may take a little longer than you think to see it go away.

1.When did Chinese people make the world's earliest paper money?

2.Why is plastic the most popular material for making banknotes? (one reason is OK)

3.What's the advantage of paper money?

4.Please translate the underlined sentence into English.

5.Please translate the underlined sentence into Chinese.

6.Do you think paper money is going away? Why or Why not?

What time of day do you feel most alert (清醒的)? Are you more of a morning person? Or does your brain need a few hours to get going? A lot of research suggests that we should pay attention to our body clock. It can tell us what time of day we are best able to perform, according to the Wall Street Journal (华尔街日报).

When it comes to the human brain, many people work best later in the morning. This is because the body’s temperature takes time to rise through the day. Taking a warm shower when you wake up can help speed this up.

But everyone’s body clock is different. Morning people will rise early and work better early in the day. Evening people will wake later but their brain will work better toward the end of the day.

Research shows that we’re better at some activities at certain times of the day. Physical performance is at its best between 3 pm and 6 pm, so it s better to exercise later in the day.

Between noon and 4 pm, people begin to get distracted. This is partly because our brain becomes less alert after we eat a big meal. Research also shows that we become sleepy around 2 pm.

Finally, it is best to eat during our active periods. This allows our body to burn calories better and stops our blood sugar levels from getting too high.

1.Many people perform best later in the morning because ________.

A.they can’t get up very early

B.thcy have to take a shower first

C.the body’s temperature needs time to rise

2.Evening people had better ________.

A.rise late and work in the morning

B.wake later and work in the evening

C.rise carly and work in the morning.

3.What does thc underlined word “distracted” mean?

A.精力充沛的 B.思想不集中的 C.容光焕发的

4.According to the research, which of the following is TRUE?

A.It’s better to do exercise in the afternoon.

B.We perform better after eating a big meal.

C.Sleeping at 2 pm is not good for our health.

5.What would be the best title for the passage?

A.Brain performance B.Research about time C.The best time to do things

According to the traditional Chinese customs, 2019 is the year of Pig, ranking as the twelfth animal in the Chinese zodiac---the Shengxiao. Many people believe that pigs are naturally fat, lazy and dirty. But are any of those things true?

●Use

It is true that pigs are fat. They eat a lot. But they are useful to us. We get more than just pork from pigs. We can use their skin to make shoes. We can use their hair to make brushes.

●Not stupid

People sometimes say: “You are as stupid as a pig.” But pigs are not stupid. In fact, pigs are one of the 10 smartest animals. They can remember things well and tell different shapes apart. Many experts think pigs are easier to train than dogs or cats.

●Stereotypes

These stereotypes (偏见) of pigs often make us feel negatively about the animal. For example, if someone’s room is very messy, we might say his or her room looks like a pigsty (猪圈).

●Ancient people’s favorite animal

But people in ancient China really liked pigs. If someone had a round and chubby face, he or she was thought to be blessed (有福气的). People also believed the animal stood for (代表) wealth. Now most children have a piggy bank that they can use to save money.

‘USA? Britain? Which country is better to study in?’ We often hear such discussions. As China opens its door, it is a dream for many Chinese students to study abroad. They want to learn about the outside world.

It’s true that studying abroad can help students develop themselves in the future. It also can help the students to improve their foreign language skills. But there are problems that should be considered. Language is the first. Students must spend a lot of time learning another language. Students must also learn to live by themselves and face all kinds of things they haven’t had to do before, like looking after themselves. There are reports about Chinese students abroad running into an ocean of difficulties and giving up finally. When they have to take care of themselves, it is hard for students to study well. Finally, studying abroad brings a heavy burden（负担）to the family. For most Chinese parents, they will pay lots of money for their children’s studying abroad. But is it worth it?

We know that there are many famous people who have achieved success through their hard work in China. Liu Xiang is a good example. Once an American teacher invited him there, but he refused. He kept training hard with his Chinese teacher. He surprised the world when he won a gold medal at the Athens Olympic Games. So when you wonder which country is better to study in, think again.

Title: Studying at　 home or abroad

Parents with high expectations for their children are nothing new to Chinese kids. However, people often don’t realize that children also have expectations for their parents. What expectations do Chinese children have for parent-child relationships?

China Youth & Children Research Center did a survey on this topic in the United States, Japan, South Korea and China. The survey found that 83.8 percent of Chinese children want to be friends with their parents, the greatest amount among the four countries. This means that they want a more equal（平等的） relationship with their parents.

According to China Youth Daily, traditional Chinese values (价值观) such as respecting one’s elders and the concept of hierarchy (等级观念) are preventing parents from becoming friends with their children. Many Chinese parents criticize (批评) and push their children, as there is lots of competition in school. It requires efforts from both parents and children to create a friendship in family. As children, what can you do to create a pleasant atmosphere (氛围) at home and make friends with your parents? Read on to find out.

Tips to make home a happy place

How can we get along better with our parents, and at the same time, grow into adults ourselves? Here are some tips.

●Act like an adult

If you want your parents to give you more freedom, you should show them that you’re ready to be treated differently. For example, learn to use self-control. Show them that you can manage your time well.

●Open your heart

US psychologist (心理学家) Carl E. Pickhard wrote in Psychology Today that sharing feelings with our parents can lead to positive changes, while not sharing them can cause misunderstandings.

●Care for your parents

Do something nice or helpful for your parents. For example, help them with some home chores, make them gifts or teach them some computer skills. Their trust in you will grow.

The concept of homeschooling is not a new one. Homeschooling means educating children at home instead of sending them to public or private schools. Nowadays, homeschooling has become popular in the USA for a lot of reasons. One of them is poor quality of education in public schools and it’s also because of the high cost in private schools. Some parents believe that because they know their child’s strengths and weaknesses, they can teach him or her better. Some parents prefer homeschooling so as to prevent their children from getting into bad company. There is another group of people who choose to educate their children at home because they want them to learn their religious beliefs. They also think that homeschooling would help in development of strong family bonds (家庭纽带).

However, there are some negative influences of homeschooling on students as well as parents.

Homeschooling is a full-time job and not fit for parents who have their own careers. It takes a lot of time for parents’ side to make homeschooling a success. Other family members’ responsibilities may also be affected. They may give their full attention to the needs of their children. Besides, a parent may have high educational qualifications, but that does not make him or her a good teacher. Teaching is an art, which requires the ability to understand the needs of the children. It may be difficult for the parents to explain the concepts to their children.

In today’s world, competition is seen in every field, and school prepares children to face these competitions. However, homeschooling does not give the children a chance to compare with other kids. They will also not be aware of where they stand in educational position among their classmates. This may affect their lives. Education is not the only thing that the children need to become successful human beings. It is necessary that they learn to communicate in the society, and public school provides them with such an environment, where they meet many people. Schools also provide children with a chance to take part in different activities to improve their overall development.

It is true that it has many advantages, but one must get to know that school teaches children skills to survive.
