The Internet is the 【小题1】 (big) source of information in the world, which consists of millions of 【小题2】 (page) of data. It dated back to 1969 when a US defense organization developed a way for all 【小题3】 (they) computers to “talk” to each other through the telephone. Thus DARPANET, a network of computers 【小题4】 (come) into being. But it was only used by the US army. Then in 1984, the NSF started the NSFNET network, 【小题5】 became known as the Inter-Network. Later an English scientist came up 【小题6】 the idea of World Wide Web while 【小题7】 (work) in Switzerland in 1989. He designed the first “web browser”, allowing computer users 【小题8】 (access) documents from other computers. From that moment on, the Internet grew. Within five years, 【小题9】 number of Internet users rose from 600,000 to 40 million. Now, the Internet is used 【小题10】 (wide) all over the world.

TikTok on Thursday began letting users post videos up to three minutes in length to stay ahead of competitors. TikTok 【小题1】 (believe) to have one billion users worldwide including more than 100 million in the United States, and is 【小题2】 (especial) popular with young smartphone users.

“ 【小题3】 longer videos, creators will be able to create new or expanded types of content on TikTok, with the flexibility of a bit more space,” product manager Drew Kirchhoff said in a post.

TikTok, 【小题4】 is owned by China-based ByteDance, remains one of the world’s most popular social media apps 【小题5】 faces competitors such as YouTube and others. Facebook-owned Instagram will be experimenting with video features 【小题6】 (ride) the hot trend, chief Adam Mosseri said in a Twitter post. Video sharing and viewing is driving a lot of 【小题7】 (grow) at online platforms, and Instagram needs to “lean into” it more, according to Mosseri. “We are no longer 【小题8】 photo-sharing app,” Mosseri said in a video 【小题9】 (share) at Twitter. “There is some serious competition now. TikTok is huge; YouTube is even 【小题10】 (big), and there are lots of other upstarts as well.”

With the development of modern technology, people can stay 【小题1】 (connect) with their families and friends easily, however far apart they are from each other. WeChat is one of 【小题2】 most frequently used means of 【小题3】 (communicate) in China. It is reported that the number of the WeChat users 【小题4】 (reach) over 1.1 billion so far.

Once 【小题5】 (join) the WeChat, people can find more and more people start to add them as friends. They don’t have to consider time zones when communicating. Another reason why it becomes so popular is that it costs nothing. It’s also very convenient for people to 【小题6】 (immediate) update what they are doing by WeChat.

However, addiction to WeChat will rob people of the time that should otherwise be spent 【小题7】 something more important. And the many so-called friends on it 【小题8】 (be) not really friends at all, 【小题9】 simply want to put ads or sell items on Moments. Besides, people on the Wechat are more likely 【小题10】 (compare) themselves with others, which will make them feel bad when finding some people seem to be successful.
