A
In the space of just two years, the app Douyin, created by Beijing-based company ByteDance, has gathered more than half a billion users—around 40%of them outside China—who share short videos of themselves lip-syncing (假唱), cooking, dancing or just being silly. What sets ByteDance apart is its success in the social media category, which is controlled by Facebook, Twitter and Snap—all Western companies.
ByteDance calls itself an artificial intelligence company. It uses machine learning and algorithms (算法) to figure out what people like most and give them more of what they want to see. On Douyin, people can edit and beautify 15-second videos before posting them online. The app has even made a phrase to describe people glued to their customized feeds: “shua Douyin” or “scrolling through Douyin”. Last year, the company released TikTok, the overseas version of Douyin. ByteDance’s growing video empire has made it the world’s fifth biggest app maker. ByteDance says TikTok and Douyin together have more than 500 million monthly active users.
Investors like ByteDance because its hundreds of millions of users attract a lot of advertising money. The video apps are lucrative because they attract a lot of users in their teens and 20s, who are more generous with the money. ByteDance also makes money through income sharing deals. People on TikTok, for example, can buy digital coins to give to other people on the app—like throwing money in a performer’s tip jar. ByteDance takes a cut of those earnings.
ByteDance’s founder and CEO is Zhang Yiming, a 35-year-old former Microsoft employee. People who have worked with Zhang describe him as someone who thinks deeply about technology and spends much of his free time writing code.
Like Facebook and Twitter, ByteDance is also battling fake news and inappropriate content. ByteDance promises to add thousands more employees to review content on Douyin.
1．What makes ByteDance so special
A．Its app challenges similar companies’ rule in Western world.
B．It is the biggest artificial intelligence company on the earth.
C．It invented the social media app initially in the world.
D．It has controlled Facebook, Twitter and Snap.
2．Why is Douyin so popular
A．It is a new generation hi-tech product.
B．It has both home and overseas version.
C．It is easy and totally free to operate online.
D．It meets the demand of people individually.
3．How does ByteDance make a profit
A．By charging the users.
B．By charging the advertisement.
C．By forcing the users to donate.
D．By selling its artificial intelligence.
4．What can be the best title for the text
A．Douyin, a Popular App
B．ByteDance, a Successful Company
C．Facebook Together with Douyin Is Batting Fake News
D．Twitter Is Helping Douyin Attract More Advertising Money
B
When it comes to modern communication, security is a big concern. It seems like we’re forever hearing about hackers leaking(泄露) emails, passwords and other important personal information.
But thanks to a breakthrough by Chinese scientists, who won the 2018 Newcomb Cleveland Prize in February, we may soon never have to worry about our data again. This is thanks to the satellite called Micius that uses cutting-edge technology to send and receive information.
Micius is the first satellite of its kind to use quantum key distribution(量子密匙分发), which uses particles (粒子) that transmit(传输) light to transfer information from one point to another. Currently, it can communicate with two base stations(基站), both of which are located high up in the mountains in two different areas of Tibet, around 1,200 kilometers apart. Data is sent between the satellite and one of the base stations in the form of a ray of light. This makes it almost impossible for data sent and received using quantum satellite technology to be stolen, as the connection will be broken if someone tries to hack it.
“Any eavesdropper(偷听者) on the quantum channel attempting to gain information … can be found by the communicating users,” the scientists wrote in the paper.
However, the technology does have a few limitations. For example, the process only works at night, as the information isn’t able to pass through sunlight.
Despite these small issues, the scientific community across the world has reacted positively to China’s achievements in this groundbreaking project.
“This Chinese experiment is a quite remarkable technological achievement,” Artur Ekert, a professor of quantum physics at the University of Oxford, told BBC News.
And Karl Ziemelis, an editor for Nature, told Xinhua, “It’s a testament(见证)to China’s investments and significant efforts in the physical sciences that this group has been able to push research in practical quantum communication technologies to such an astronomical(天文学的)height.”
5．According to the passage, why Micius is safe for transporting messages
A．Because it is only data base located in space, which cannot be touched.
B．Because it only works at night, as the information isn’t able to pass through sunlight.
C．Because it uses particles that transmit light to transfer information from one to another.
D．Because it doesn’t score any important private information like passwords and e-mails.
6．Which of the following can best describe scientists’ words in the paper
A．It gave out the working principle of Micius.
B．It tells of a kind of scientific appearance.
C．It warned hackers not to steal information from Micius.
D．It is a more apparent explanation of its safety.
7．What’s the main problem of Micius
A．Its core technology is controlled in foreign countries.
B．Light is a must in its working process.
C．Its safety performance needs improving.
D．Sunlight has a deadly influence on its working.
8．What’s the best title of the passage
A．Leaping into an age of secure data
B．How should you avoid information hackers
C．Old Problem, New Approaches
D．Taking on data theft

The more advanced technology becomes, the more it seems to have control over our lives. We shop, work, play, search for information and seek 1． (chat) with each other online.

You can see them every second of every day, and hear nearly every single thought of theirs just as they hear 8． (you).

【参考答案】
这是一篇说明文。谈到现代通信，安全是一个大问题。似乎我们总是听到黑客泄露电子邮件、密码和其他重要的个人信息。最近中国发射了一颗名为“墨子号”的卫星，它使用尖端技术来发送和接收信息。我们可能很快就再也不用担心数据安全问题了。
5．推理判断题。根据第三段第一句Micius is the first satellite of its kind to use quantum key distribution(量子密匙分发), which uses particles (粒子) that transmit(传输) light to transfer information from one point to another.（墨子号是第一颗使用量子密钥分配（quantum key distribution，量子密钥分配）的卫星，它使用传输光的粒子将信息从一个点传输到另一个点。）可知，因为使用量子来传输，所以不会泄露重要的个人信息。故选C。
6．推理判断题。根据第四段“Any eavesdropper on the quantum channel attempting to gain information … can be found by the communicating users,” the scientists wrote in the paper.（科学家们在论文中写道：“任何试图获取信息的量子信道窃听者……都可以被正在通信的用户发现。”）可知，科学家在论文中的表述讲述了一种科学现象。故选B。
7．推理判断题。根据第五段中For example, the process only works at night, as the information isn’t able to pass through sunlight.（例如，这个过程只在晚上进行，因为信息无法通过阳光。）可知，墨子号卫星的主要问题是阳光对它的工作有致命的影响。故选D。
8．主旨大意题。根据文章主要内容为介绍中国“墨子号”的卫星，它使用尖端技术来发送和接收信息，从而保护人们的信息安全。预示着我们将会进入数据安全时代。故A选项符合题意。
