1 . If you look at the top of your phone, you'll see a little symbol that says 3G or 4G. The "G" stands for the "generation" of your mobile network. But these symbols will become things of the past after the SG network fully arrives.
The 5G mobile network is 100 times faster and has 1, 000 times more capacity(容量) compared with the 4G mobile network.
In recent years, China has paid great attention to the commercial(商业的)use of 5G and made great efforts to introduce the infrastructure(基础设施)for a 5G network. On March 30，Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported Shanghai has also become the first city in China to start testing 5G networks.
5G will let people download and upload data faster than ever before. But 5G won't just bring faster mobile Internet. People can use it for many other things as well. For example, 5G will help to make self-driving cars safer. Today's self-driving test cars have one problem一lags. When the car "sees" something or somebody in the way, it sends this information to a data center and receives instructions.
However, it takes time to send and receive this information. With this kind of lag, the cars might crash because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer, according to CNN.
5G could also be used to power the Internet of Things(IoT). This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. For example, with IoT, your refrigerator could order eggs online when it notices that there are no eggs left inside.

2 . Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website BookCrossing.com turns the page on the traditional idea of a book group.
Members go on the site and register (注册) the books they own and would like to share. BookCrossing provides an identification number (标识号) to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure (冒险), traveling far and wide with each new reader who finds it.
Bruce Pederson, the managing director of BookCrossing, says, "The two things that change your life are the people you meet and books you read. BookCrossing brings them together."
Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.
People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossers to keep them updated (更新) about where their books have been found. Bruce Pederson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.
BookCrossing is popular with people who want to get back to the "real" and not the virtual (虚拟). The site now has more than one million members in more than one hundred and thirty-five countries.

3 . Perhaps you've seen the English letters "WC" in your city. They show public toilets. But do you know it is far from elegant English? In fact, foreigners from English-speaking countries rarely use the letters.
Workers in our city are changing "WC" signs all over the city. The government is spending much money changing all the bad English on signs and restaurant menus. Many other places in China are following our steps.
"WC, or water closet, is old-fashioned English. It sounds dirty to me, " says Charlie Shifflet, a young man from the US. The old sign will become "Gents/Men" and "Ladies/ Women".
"I see lots of poor English in everyday life, and not only on signs, " he says. "I know what they mean. But they are Chinglish, not real English. For example, when someone says to me ‘My hometown is Henan Province’, I know he would say: ‘My hometown is in Henan Province’. ‘Hometown’ is a smaller place in a province.” The common mistakes he picked up include "Not Entry", which should be "No Entry", "Direction of Airport" should be changed to "To the Airport". And it is "room rate", not "room price". And remember to "Keep off the grass", rather than "Care of the green".
