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（延迟） 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
5G 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.

Millions of young people are writing blogs. Millions of other people are reading them. The word “blog” is short for “web log”.
Many popular websites now offer free, easy ways to create personal web pages. Websites like Facebook and MySpace are some of the most popular sites for people’s daily activities. They give people a place to write their ideas and opinions about how they think of others’ ideas.
Blogs offer young people a place to show their writing and feelings. They can also help people communicate with each other. But blogs can become dangerous when they are read on the Internet by millions of people all over the world.
Recent studies show that young people often give out their names, age and where they live on the Internet. That may not be safe for them. The personal information puts them at the risk (冒险) of being searched out by dangerous people who want to hurt them. Students can also get into trouble when they put others’ information on their blogs.
As a result, many schools have banned the use of blogging websites on school computers. Many schools have also begun teaching parents about the websites. Parents should know what their children are doing online and should read their blogs to make sure they are not giving out private (私人的) information. One way to keep away from their problems is to use programs so that blogs can be read by “friends only”. People can read the website only if they know a secret word chosen by the blogger.
