    A new report from a university says 80% of the world's teens don't get enough exercise very day. The report was based on (基于) a research done with about 2 million students aged 11 to 17 around the world. According to the report, activity standards are different in different countries and they are also different between boys and girls. In China, for example, only 20% of the boys are active enough, compared to 11% of the girls.

Why don't teens go out for exercise? One main reason is that they always have technology products in their hands or around them. They spend too much time on smartphones, computers and TVs in their free time. Many teens find it very hard to pull themselves away from these devices (设备). The report says that young people need to do less in the digital world but more the real world. It advises kids to get at least an hour of exercise every day. This could include running, biking, playing sports, or many other outdoor activities.

More and more research shows that exercise not only helps the body, but also helps the brain. Besides, doing sports helps kids to make friends. Mark, a sports fan, started to play football when he was six years old. He used to be shy and weak, but now he has become taller and stronger. He gets to know the importance of communicating with his teammates and hoy to learn from mistakes and failure. And he has made lots of friends with the same interest. They often have football training on the playground. They have more to talk about and enjoy the happiness after training.

根据短文内容,回答下列问题。

1.How many students around the world took part in the research?

___________________

2.Are activity standards the same between boys and girls according to the report?

___________________

3.What does the report advice kids to do

    The novel coronavirus (新冠病毒) has changed our lives. In many countries, it has also changed the way people greet each other. To help stop the spread of coronavirus, people give up their usual greeting styles and invent safe ways. Let's take a look.

1. Lean forward (倾身向前), touch faces and make a sound. French people's favorite way of greeting. But when the virus is going around, too many kisses are not good. An expert gives everyone in France a suggestion: simply looking into a person's eyes can be a greeting. It's not as romantic as kissing, but it's safe.

2. Like the French, Italians are also romantic people. When they meet, they always hug or kiss each other. Recently, an Italian grandma made a video to help everyone fight the disease. According to her, if you want to say hello to others, do not hug or kiss. Instead, you can close one of your eyes and give them a wink (眨眼). Isn't it cute?

3. It's a very Australian thing to put your hand out to shake hands. But if you do this, the virus can jump from one person to another. Now a health official (官员) in Australia says a pat (拍打) on the back would be better. But it also has some problems. For example, it's a bit impolite if you do this to your teacher. What do you think?

4. People in Iran often shake hands when they meet. But a recent video shows that an interesting way to greet others is now popular in Iran. In the video, three Iran men wear masks and put their hands in their pockets. They don't shake hands, but try to "shake" feet.

5. An official from the WHO suggested that we use three greetings: waving hands, Thai "wai" (泰式合十礼) and bumping elbows (碰肘礼).

A.The advice from the WHO.

B.No kissing, even if you are French.

C.Is the foot shake the new handshake?

D.Pat on the back.

E.Grandma has a good idea.
