It is everyone's duty to help animals to stop extinction (灭绝). As a student, there are so many things you can do yourself too! Please look at the following tips (建议) to help the endangered animals.
Send a letter to your local environment protecting center and show how you feel about the quick extinction of animals. Use the facts to write what you have found. Give some advice to the officers who make the strong rules to save animals.
Draw pictures and make a poster. Put this poster somewhere at school or where people will usually see it. Add some texts in the sign to make it clear why you care about the loss (丧失) of animals. It may encourage people to do something to protect the animals.
Avoid buying things that come from endangered species (物种). When you travel, be careful about what you buy. You shouldn't buy things made from endangered animals or endangered tree species from forests that the animals live on.
Watch your diet. Before eating meals, you should see if you will break a food chain. If you see somebody doing something bad for the food chain, please stop him at once.

To many people, art is a human expression of creativity. But in recent years, you may have read news about artificial intelligence（AI）creating its own art, such as painting or writing poems. Some people worry that AI might someday replace（替代）artists.
But this worry seems to be unnecessary, at least for now. Many artists today are turning AI into a useful tool. Instead of replacing artists, AI is bringing artists more possibilities.
A piece of music created by AI recently attracted attention. AI was used to create the music based on the protein（蛋白质）structure of COVID-19. The music lasted nearly two hours. The project was led by Markus Buehler, an American musician and MIT professor（教授）of engineering. He assigned (指定) a unique note (独特的音符) to each amino acid (氨基酸) is the protein. The AI then translated these notes into music.
Listeners found the project “mind-blowing”. “It allows me to see the virus in a new way,” said one listener. This surprising combination (结合) between science and art could not be achieved without AI. As The Verge wrote, “AI helps artists play around in unpredictable ways, creating things beyond (超过) what they have ever thought was possible before.”
Apart from creating imaginative works, AI can also take care of repetitive (重复乏味的) tasks for artists. For example, in the comic and cartoon industries, there are now AI tools that can automatically (自动) color in black-and-white line drawings. Although the results can be unpredictable and require a little cleanup. it can give artists room to experiment (实验) by cutting down the time it takes to color each picture.
As Peter Ward wrote for The Culture Trip. “Art of every kind has always been influenced by technological developments.” AI can become a useful tool to bring change to the art world if it’s welcomed and not unfairly feared.

3 . Do you know 5G? It is the fifth generation（代）of mobile network technology. These new networks are coming.
China just issued commercial licenses（发放商用牌照）for 5G on June 6, 2019. This means that China's telecom companies will be able to offer 5G networks for mobile phone users.
Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data（数据）and the Internet. And 4G made all of these things faster. What's special about 5G?
5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds（毫秒）to send and receive data. But 5G will get it down to 1 millisecond or less-this is almost real-time.
'This big change will not only make our mobile Internet faster，but also deeply change our lives. Read on to find out how.
5G + entertainment（娱乐）
5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.
Also, virtual reality（VR）games will become more popular with 5G. The short delay of 5G will make the games feel even more real.
5G + transport
5C will also bring us safer self-driving cars. These cars can send signals（信号）to each other. They also talk to traffic lights and road sensors（传感器）. 5G will allow cars to react（反应）even faster than human drivers.
5G + smart homes
5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.
For example, your toaster can automatically（自动地）start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler（洒水器）could water your plants by itself.
1. What's the writer's purpose in writing the third paragraph?| A．To explain 5G is the best of all. |
| B．To share his knowledge about 5G. |
| C．To encourage people to use the new network technology. |

| A．5G will change our lives in many ways. |
| B．Mobile networks are changing for better. |
| C．5G will make the Internet of things possible. |
| D．5G networks for mobile phone users are coming. |
The Chinese version of TikTok, called Douyin(抖音), has amassed(积累) 400 million daily active users, parent company ByteDance revealed in its annual report this week. This is an impressive growth for the addictive(上瘾的) video app, which had 250 million daily active users in January last year.
The report, which describes the user behavior and trends, illustrates(表明) the cultural difference between China and the U.S., said Katherine Wu, an investor at New York-based firm Notation Capital. "Things that trend in these two countries are quite different. For example: knowledge-based content is extremely popular in China, and less so in the U.S. Also, this was wild to me: those creators that did the most dance videos in China are users born in the 60s (!!), whereas in the US, it seems that it's mostly teenagers who are creating the dances," she wrote.
ByteDance claimed (宣称) that Douyin has established itself as the largest knowledge, culture and art platform in China. (Douyin is only available in mainland China.) Indeed, 14.89 million "knowledge-based content videos" were shared on the app last year, it claimed.

6 . Following the rule of "social distancing" is probably well-known to us all now. It refers to staying away from crowded places to prevent the spread of COVID-19. Some companies are taking advantages of this by changing their logos.
Coca-Cola, for example, placed the letters of its famous brand further away from each other to show social distancing. The encouraging sentence "Today, being apart is the best way of being together." is printed below the logo. McDonald's Brazil has separated its famous arches(拱门)in a picture posted on its Facebook page. Other global companies, including Audi and Nike, have also posted similar logo changes online.
Although many people think this idea is creative, some believe it makes "social distancing " seem less serious. What do you think of it?

7 . In Britain, Australia, Canada and a few other English-speaking countries, people don't stop celebrating when Christmas Day is over. They also celebrate the following day, known as Boxing Day. It is a popular day for giving additional（另外的）gifts. It has been celebrated for so long, but nobody exactly knows how it started.
Some people believe Boxing Day began in the Middle Ages. In those days: in some special places there were special collection boxes where people threw money for the poor.
The day after Christmas the boxes were opened and the money was counted. Then the money went to helping the poor in the area.
Others believe Boxing Day started about 300 years ago when some rich people had Christmas feasts (盛宴). They offered lots of food to their guests. Because many servants (仆人）were needed to make and serve the food, they could not celebrate Christmas with their families. To thank them, the rich people would put food into boxes for their servants to take home.
Now Boxing Day has become a public holiday in some countries. Some people spend the day boxing up old or unwanted things and donating（捐赠）them to the poor. Many people are active in helping service organizations(组织)like the Red Cross.
No matter how Boxing Day got its start, it's a wonderful time to donate things or give small gifts to people. By doing so, you cam make someone's holiday much happier.

8 . Yun Siqi from Beijing is a 19-year-old young pianist（钢琴家). He started to learn the piano at age 4 and it has been his favourite hobby since then. Before that, he often heard his elder sister playing the violin and he loved the classical music she played. "I wanted to beat her in something and I chose the piano," Yun said.
