There has been a lot of publicity (宣传) recently surrounding 5G, the next generation of wireless technology for the world. But what is this technology and how might it change our lives?
What is 5G?
5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system. 4G was the replacement for 3G, which came after 2G, and so on. These systems are wireless computer networks. Earlier “G” systems were designed to improve mobile communication operations. Each new technology brought major improvements in speed and greatly increased network capacity. The new 5G system promises more of the same. It is expected to permit more users to do more things-at a faster rate. Higher internet speeds and larger network capacity should result in better performance for device users connected to 5G. However, technology experts say there is a major way that 5G is different than the earlier systems. It will move well beyond mobile network technology to affect many more devices and industries than other “G” versions.
When will it be available?
Before we can all use 5G, wireless companies and phone makers will have to complete and deploy (部署) a whole new system. New phones and communication equipment must be built. American wireless companies have been preparing for the new system for some time. They have been creating new network equipment and buying broadcasting space to carry 5G signals. They have built news G antennas(天线)to serve American cities and towns. Wireless providers will invest at least $275 billion n 5G-related networks in the United States, the industry group CTIA reported. The first U.S, launch of 5G is expected to happen sometime this year. Industry experts expect it will take a few more year to go nationwide. It will take even longer to reach rural areas. China is expected to launch 5G sometime in 2020, while European nations are likely to build their systems more slowly over time.

A 3-year-old boy who was lost in the woods is now safe at home with his family. But Casey Hathaway told his rescuers that he was not alone in the rainy, freezing cold woods. He said he was with a friend—a bear.
The child went missing on January 22 while playing with friends at his grandmother’s house in the southern state of North Carolina. When the other children returned to the house and Casey did not, the family searched the area for almost an hour before calling the police.

“Food is the first necessity of the people” is a famous Chinese old saying, which reflects that Chinese have paid much attention to food since the ancient times. The importance of food in people’s daily life in China can be seen in the way they send greetings to each other, “Have you eaten?”, which is far away from the way people greet in western countries and has been seen as a characteristic of Chinese culture.
Food in China generally includes rice, wheat, buckwheat, corn, potato, sweet potato, beans and varieties of vegetables. Besides, wheaten food such as Mantou (steamed bun), noodle, Youtiao (deep-fried dough stick), Xiaolongbao (steamed pork-stuffed dumpling in bamboo basket), and: many other local snacks, are commonly seen on the table in China.
Regionally, a general feature of spicy east food, sweet south food, sour west food and salty north food can be summarized, but flavors of food in places differ from each other as a matter of fact. Generally, people living in South China pay more attention to nutrition and prefer delicate, tasty and refreshing food such as rice porridge and soup; however, spicy hotpot is always people' s favorite in the southwest areas due to the wet and rainy climate. And, people living in North China prefer wheaten food such as Jiaozi, noodles, while all kinds of steamed bun and beef and mutton are most popular in northwest areas.

A friend of mine whose name was John Smith had a bad memory, which made him famous. He was so forgetful that he sometimes forgot what he was talking about in the middle of a sentence. His wife had to constantly( 经常地）remind him about his meetings, his classes, even his meals! Once he forgot he had eaten breakfast twice, at home and at school. His wife liked to remind her neighbors, “If John didn’t have his head tied on, he would forget that too!” Since Smith was a professor at a well-known university, his forgetfulness was often an embarrassment to him. It wasn’t that he was not clever, as some critical people tended to say, but just very, very absent-minded.
One hot summer day, Pro.Smith decided to take his children to a seaside town about a three-hour train ride away. To make the trip more interesting for his young children, he kept the name of the town a secret. However, by the time they arrived at the station, Smith forgot the name of the town he was planning to visit. luckily, a friend of his happened to be in the station. He offered to take care of the children while Smith hurried back home to find out where he was going.
The professor’s wife was surprised to see him again so soon.
“Oh, my dear, I forgot the name of the town.”
“What? You forgot the name? Maybe one day you will forgot my name! Now I’ll write the name of that town on a piece of paper, and you put it in your pocket and please, please don’t forget where you put it.”
Satisfied that she had solved the problem, she sent her husband off again. Ten minutes later she was astonished to see him outside the house for the third time.
