A 12-year-old girl from Virginia, US, never thought that a simple message she put online could bring her big problems. She posted the words, “Killing. Meet me in the library Tuesday”, with three emojis(表情符号) of a gun, a knife and a bomb(炸弹) on Instagram, a social media(社交媒体). She was told that she broke the law because of threatening(威胁) her school.
This problem is not far away from us. Not long ago, Ni Hanxiang, a Chinese student at a university in the US, was sent back to China after expressing on social media that he would kill his teachers if he failed to pass his exams.
In China, posting threatening words online is also against the law. In 2013, Wu Hongfei, a singer, got into trouble for saying on weibo that she wanted to blow up a building.
“Threatening happens not only face to face but also through the Internet, social media and the telephone,” said Mr. Cao, a lawyer from Chongqing. “Although the law of China protects people’s right of free speech, it doesn’t include words that threaten others’ lives and national safety.”
“Some people may not mean to threaten. They may just be trying to say “I’m strong”, said Fred Pratt, a lawyer from the US.
The girl’s mother said her daughter was a good kid who had never been in trouble before. Ni Hanxiang also said he didn’t realize that what he put online was so serious.
“But not knowing the law doesn’t mean the law will treat you any differently if you break it,” says David Allen Green, a lawyer from the UK. So, do you think we’d better spend a minute or two thinking about the words or emojis we use on social media before we press “send”?

Whether from news reports or social media articles, you may know that 5G is coming.
5G is the 5th generation network. It is a new network(网络)after 1G, 2G, 3G and 4G and it can connect everyone and everything together. 5G networks will cover many cities in China soon. 5G means super-fast data(数据) speed, one can download a two-hour movie for fewer than 10 seconds, and it is making our lives more and more convenient.
5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission(传输)to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Eyen airplanes will become "smart" in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet or place orders for food and drinks.
5G will be a big help for students who take online classes. Many people live in poor areas in the world where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.

Someone's always watching you online...
How do they get my information? Did you know that when you surf the Web, many websites put secret software on your computer? The software collects a large amount of information about you and sends it to Internet companies. The Internet companies sell it to other businesses. Your personal information can also be collected from social media（媒体）sites. There are many ways your information can be used.
What information do they collect and why? First, companies collect your information. The companies find out where you live, what websites you visit, and what you do online. With this information, they can guess other things about you. For example, they can guess if you are male or female, how old you are, and your interests. The companies use this information to decide which advertisements（广告）are best for you. Two people can go to the same website, but they will see different advertisements. For example, someone who likes sports could see an advertisement for sneakers, and someone who like films might see an advertisement for movie.
What do they do with my information? Your personal information could also be sold. Some companies collect information just so they can sell it to other businesses. A business that collects and sells personal information is called a data broker. When data brokers sell your information, a lot of different companies will know your online habits. Then these companies will advertise products or other websites to you.
What online habits are tracked（追踪）? Another way your personal information can be collected is through social media. When your information is on social media, a lot of people can see it. Even if you don't use social media, a friend might post a picture or video of you with your name on it. Pictures and videos can be shared for free on social media, which is one of the great benefits（福利）. However, that same act of sharing could be problem for your own security（安全）. If someone knows too much about you, they can steal your identity（身份）. Then they can buy things online and post messages while pretending（假装）to be you.
Conclusion. All of your online habits can be recorded. Studying people's online habits is big business. Your personal information is very valuable to companies. That is how they know who to send their advertisements to. The Internet reaches almost every corner of the world, but the danger is that your personal information might travel that far, too.
正确的，涂A：错误的，涂B。
1.All businesses collect a large amount of information about you online.
2.People who go to the same website may see different advertisements.
3.Data brokers collect your personal information for money.
4.If you don’t get online, your information will be safe.
5.Your personal information can go anywhere with the Internet.

Social media(媒体)is a big part of most people’s lives. There are social apps and sites like WeChat and Sina Weibo, as well as video apps like Douyin and Kuaishou. How do you behave when you use these apps?
Recently researchers at the University of Sussex, UK, studied social media users ranging from 10 to 15 years old. They found that they can be divided into four personality types.
Geeks(极客)
Geeks are active social media users，but they find it mush more difficult to deal with the life in the real world. Most of them are boys who like playing computer games and making music and videos. They often post creative works online, using fake(假的) names. In fact, they should avoid spending too much time on the Internet.
Internet celebrities
Internet celebrities like sharing as well , but they are much more visible (看得见的) than geeks. They might become well-known for their singing or dancing. But many of them, especially teenagers ,share almost every side of their lives in order to own more fans. Being a teenage Internet celebrity can sometimes cause problems in the real world.
Lurkers(潜伏者)
The first two groups are lucky to find a place to show their talent. But most teenagers fall into the third type---- “lurkers”, or people who are neither too active nor visible. This group prefers WeChat over Sina Weibo, as WeChat has private groups. They can’t express themselves well but at least they make sure to protect their personal information.
Victims(受害者)
Victims don't have enough knowledge to keep themselves safe online Their personal information can be made public and cause problems for them. To avoid being a victim, you should check your personal settings on social media.“Friends only” is a good choice for your posts. Don’t share your personal information.

These days, teenagers are heavily influenced by the media. Many of them have watched thousands of hours of TV. That's more time than they spend with teachers at school. And we haven't yet considered the hours they spend using the Internet and reading newspapers.
However, several studies have shown a serious problem: today's teenagers lack media literacy (媒体素养). In other words, they have difficultly critically thinking about the information they see. One study that was done on middle school students showed that more than 80 percent of them couldn't tell the difference between real stories and ads that looked like news.
Standford professor Kevin John teaches a class called Media Effects. He tries to help his students learn media literacy. The professor gave an example that shows why media literacy is important. In the example, two news stations report a snowstorm. One focuses on (关注) the terrible road conditions. The other focuses on kids playing in the snow. "With a news story. news stations tell you what they feel are the important details (细节). These details mostly depend on the opinions of the news director." said John. "A person who has media literacy would realize that each story is about one side at this time. There is more going on."
Some experts think shoe is the best place to teach media literacy. Other believe everyone—form parents to reporters—should help teenagers learn the skills.
As for the best time to start learning media literacy, many experts suggest the age of 12. But some basic ideas can be taught even earlier. "It's never too early to start learning media literacy," John said.
1.From the first paragraph, we can learn that teenagers today spend more time ______.
A.using the Internet than watching TV
B.watching TV than studying at school
C.studying at school than reading newspapers
2.The underlined word "lack" in Paragraph 2 probably means ________.
A.缺乏 B.质疑 C.误解
3.The example shows that a person who has media literacy _______about a news story.
A.should have the same opinions as others
B.could think about is good and bad sides
C.must know about all the important details
4.Professor Kevin John would agree that _______.
A.everyone is supposed to help children learn different skills
B.children should be taught media literacy as early as possible
C.news directors should report the news children are interested in
5.The main idea of the passage is _______.
A.how to develop teenagers' media literacy
B.where teenagers should be taught media literacy
C.why teenagers are supposed to have media literacy

How to improve body and mind at home
To most people, holiday is a time to stay at home and have a good rest. Thanks to social media, computer games and online TV series and movies, staying inside is great fun. But too much time on media and digital entertainment could be a heavy burden to both the mind and eyes. Here are five activities you could try to get away from the screen for a while.
1.
If you choose a good book, it can help you enjoy a whole day at home. The ability of your brain to process words could be greatly improved through reading. And your vocabulary could be enlarged as well. Personally, paper copies are suggested. The touch and smell of real paper has no digital replacement.
2.
Everyone can write something, even if it may look very ugly at first. But the point of such practice is not to write beautiful characters. It’s about improving your ability to calm down and focus, as you must breathe deeply to keep your hands from shaking when practicing handwriting.
3.
You can just pick up a brush and draw anything, either nearby or something you imagine. Copying paintings is one nice beginning option. Copies of the Dunhuang Mogao grottoes are a good choice.
4.
Chopin, Mozart, Bach. Any of these great musicians could attract you with their works of art. Even if you prefer pop music, give classical music a chance.
5.
Many Chinese people, especially women, are crazy for yoga. Now it is a good time to practice yoga every day to relax your body. Likewise, you can try tai chi, which can improve both mind and body.
A.Read books, or at least listen to them.
B.Just listen, and let your brain and ears take a break.
C.You don’t have to be professional before picking up a brush.
D.While improving your mind, your body should also be cared for.
E.Drawing is natural pleasure that has a long history and it is still fun.
F.There are online audio lessons to help you learn a musical instrument.

Do you dream of having a sister or brother？According to the recent CCTV news report，China has relaxed its onechild policy (政策) to twochild policy. The government has allowed families to have two children.
Tencent did a survey last week about the twochild policy. On the one hand，up to 53% of parents say they are willing to have a second child. “I am excited about hearing the news. To have two kids means the children can look after each other in the future. Not only can they have a partner to play with，but they can also learn to help one another. This helps them to develop a better personality. I think I won't miss the chance to own a second kid，” says Li Mei，a mother of a 5yearold daughter from Shanghai.
On the other hand，about 40% of parents say they may not have a second child. One reason is that they are afraid that the child's everyday expenses (费用) and education would be a big problem. They couldn't afford them. “I think the policy itself is pretty good，but I don't think it interests me. I won't consider a second child. Everything is very expensive at present，and I find it very difficult to raise another child，” says Han Dong from Chongqing，who has just had a boy.
Though people have different opinions，they agree that China has made great progress already in the twochild policy.
1.China has relaxed its twochild policy to onechild policy.
2.According the survey, up to 53% of parents say they are willing to have a second child.
3.According to the passage, we know Li Mei has a son.
4.Some people may not have a second child because they couldn’t afford the child’s everyday expenses.
