Did you spend much time lying on the comfortable sofa at home during the summer vacation? How often did you do sports this summer? People across the world need to get moving, according to a new study by the World Health Organization (世界卫生组织).

    5% of adults do not get enough exercise, according to the study. This number hasn't changed from 2001. Because of this, about 1.4 billion people are close to deadly diseases (疾病) such as heart disease and cancer (癌症).

    People should do at least 2 and a half hours of "moderate intensity (中等强度)" exercise each week, such as dancing or swimming. They can also do 75 minutes of "vigorous intensity (高强度)" exercise, such as running or playing soccer, according to the WHO.

    As for how to exercise more, experts says that we don't have to go to the gym (健身房) every time For example, we can go up and down stairs (楼梯) a lot instead of taking the lift. If we can't go to a dancing class each week, standing on one leg for 30 seconds a day is very good too.

    The study also found that women are less active than men, 32% of women hardly ever take exercise, compared to (比较) 23% of men. Women spend more time at home taking care of children and doing housework.

    But unlike that in most other countries, men are less active than women in China, with 16.6% of men and 12% of women not getting enough exercise.

How can you remember a song for a long time? Why does your teacher use songs to teach you English? There is a scientific reason for this. 

Researchers (研究者) are studying the relationship between music and remembering a foreign language. "Singing could be a new way of learning, especially for a foreign language. The brain likes to remember things in a catchy (悦耳易记的) and relaxing way. For example, children can remember difficult words quickly when they are in a song," said Dr. Karen Ludke. If children find it difficult to learn foreign languages, this new way may help. On his blog (博客), Dr. Ludke wrote "A listen—and—repeat singing way can help to learn foreign languages and open the door for future research in this area."

Many language teachers know the importance of music and they often use it in teaching and learning. Hua Zhuying, a teacher at a Chinese language school in Washington DC, likes using songs in teaching Chinese. She said, "I use music all the time to teach children Chinese. For little kids usually we use English songs but teach them the Chinese lyrics. Not only does it work, but it is fun for children. Sometimes I think if I learned English that way when I was young, maybe I could speak English much better."

Our brain likes music in learning languages, especially for remembering. If you are still having problems in learning a language, why not try singing it out?

My good friend

Hello, everyone! My name is Bob.

①We know that with thousands of years of developing, people are becoming better at languages. But at the same time, language can also affect(影响) us in different aspects(方面).

②First, many studies on bilingual(双语) people show that when people change between two languages, they must think more actively than just using one, especially in the prefrontal cortex. This part at the very front of our br aın is important for handling(处理) information. And bilinguals learn new languages faster. Bilingualism might make the brain stronger. One researcher found that lifelong bilinguals often get brain illnesses later than those who know only one language. Another study shows that bilinguals get well sooner.

③Language can also affect how we see the world. Studies show that English speakers think of time from back to front. But Chinese speakers think of time in the opposite way. A study found that Greek speakers could find out different colours of blue faster and better than English speakers. People who speak languages like Spanish and French may connect words with men or women traits(性状).

④What's more, language might shape(塑造) our personality(个性). Bilinguals sometimes describe the same picture differently depending on the language they use. Studies also show that bilingual children are better at understanding others' ideas.

⑤In short, language seems to have a bigger affect on us. The more languages we learn, the cleverer we might be. There's still a lot to learn.

 Dear Alice,

 In your letter, you say you don't know the daily life of Chinese students. Now I'm writing to tell you more about myself and my school life.

I am a1 girl. I live in a town in Gaozhou. It's not very far from the city center. There is a small forest near my house.2 forest is very beautiful with many trees and flowers. In the evening, I often take my dog Happy there for a walk.

 Our school is just one street across my house. Sometimes 3 I'm having breakfast, I can see my friends going to school. Then my mother often 4 , "Hurry up, or you will be late for school."

 Our school starts at eight o' clock 5 Monday to Friday. My favourite subjects 6 English, science and biology. Some scientific experiments(实验) are really 7 . To be honest, however, I'm not good 8 maths, but I will keep working on it.

 After class, we often talk with each other about today's classes or play in the playground.

 In the evening, I often have dinner with my parents. Sometimes they help me9 my homework.10 happy my family is!

 This is my daily life. What about yours?

Yours,

Anna
