In recent years, with the     1     (develop) of technology, many popular apps (应用程序) has been produced. These days, an app     2     (catch) great attention. It is Douyin, a video sharingapp. Douyin first appeared in 2016. Now it is many people’s favorite app,     3     (especial) the young.

With Douyin, users can record videos, edit (编辑) them and     4     (share) them online. It is very easy and interesting. We can share our videos with our friends with just a tap on the mobile phone screen. What’s more, it’s a great way     5     (spend) our free time by looking through those funny videos.

    6    , every coin has two sides. The app also has bad thing. On the one hand, some people spend long hours     7     the app, which is     8     (harm) to their health. On the other hand, users can also find some bad thing on the app. Such thing is unsuitable and meaningless.

In my opinion, Douyin should check the videos     9     they are uploaded (上传) in order to keep a     10     (health) environment for its users. Douyin is not good for teenager. We should not use it too often.

“I am feeling very good. We want to report to the motherland and the people that we have    1    (success) completed the Shenzhou XIII mission. We wish to thank President Xi Jinping for his care and attention. We thank all the Chinese people for their support and    2    (encourage). Our gratitude also goes to all those involved in our mission who stayed with us day and night,” Zhai, the mission commander, told China Central Television.

Wang Yaping, the first female Chinese spacewalker, told the State broadcaster that she was very happy    3    (return) to the motherland and wants to tell her young daughter that “mom has come back after    4    (reach) for the stars”. The classes were also special to Wang, as she was the one who gave the    5    (nation) first space-based lecture inside an experimental space station module to more than 60 million Chinese students during the Shenzhou X mission in June 2013. That lecture made China the    6    (two) country, following the United States, to give a lesson to schoolchildren from space.

In the last hours of their stay inside the Tiangong, the astronauts    7    (work) with ground controllers to configure the station, transmit some experimental data back to Earth and sort out materials, according to the agency.

Zhai and his crewmates    8    (spend) 183 days in an orbit about 400 kilometers above the Earth after their Shenzhou XIII spacecraft    9    (launch) on Oct 16. The crew set a record for China’s    10    (long) spaceflight, almost doubling the previous record of 92 days created by their peers in the Shenzhou XII mission.

It’s four o’clock in the afternoon. Some students    1    (talk) about the future. Here is one of their predictions.

I believe we will be able to live in the space. There    2    (be) many big clean hotels in the space. We can fly our rockets to the space hotel there. And also we     3    play) sports and enjoy all kinds of interesting food in the sky.   — John     

Lisa Hawkins loves riding her BMX bike （极限单车）and her dream is to go to the Olympics. Lisa first got interested in BMX racing at the age of ten.

【推荐2】Some people believe that schools will not be necessary in the near future. They say that because of the Internet and other new technology, there is no need for school b    1     , classes or teachers. Perhaps this will be true one day, but if the world had no schools, I couldn’t imagine how our society would be.

In fact, we should learn how to use new technology to make schools b    2    . We should invent a new kind of school that is l    3     to libraries, museums, science centers, labs and even companies. Companies should create learning programs for schools. Scientists could give talks t    4     the Internet. TV networks and local TV stations could develop programs about the students who are studying at school. Labs could set up w    5     to show new technology so that students could see it on the Internet.

Is this a daydream? No. This is beginning to happen in many cities. In those cities, learning can take place at home, at school and in the office. Businesses provide programs for schools and society. Schools provide computer labs for people with their own computers at home. Everyone can visit faraway libraries and museums as easily as n    6     ones and everyone can go on the Internet, and older people use it as much as younger ones. How will this new kind of school c    7     the usual way of learning? It is too early to be sure, but it is fantastic to think about it.

【推荐3】Traveling to space is no    1    (long) just a dream. But what about a space vacation?     2    Aug. 16, 2011, a Russian company reported plans for a hotel in space.

The hotel     3    (open) in 2016. The four cabins(舱) in the hotel can house a total of seven guests. The most    4    (excite) part will be the huge windows with views of Earth rotating(地球自转) below.

Guests in the hotel can live a more    5    (comfortably) life than astronauts in space. They'll be able to take showers and enjoy good food and drink, such    6    beef, potato soup, iced tea and fruit juice. The company will prepare the food on Earth and send it up by rocket.

A five-day stay in the hotel will cost $100,000(1 million yuan).     7    (get) there will cost even more and will take two days by a Soyuz(联盟号) rocket. Guests will have to    8    $500,000 in total for their space holiday.

Space     9    (tourist) might also meet some     10    (expect) guests. If there is a problem at the International Space Station, astronauts will use the hotel for shelter(避难所) .
