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 delaybetween 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.

In every school there is “top” crowd that sets the pace, while the others follow their lead. For example, if the crowd decides that it is smart to wear bright red sweaters, then very soon everybody is wearing bright red sweaters.
There is nothing wrong with that, except the fact that for some people bright red sweater is really unsuitable.
The situation can even become dangerous, if the top crowd decides that it is smart to drink and to drive cars at seventy miles an hour. Then the people who follow the lead are endangering their lives. They are like the sheep being led to the slaughter(屠杀).
Now it’s possible that you have come across situations like these more than once in your life. In fact you probably did something you knew to be wrong one time or another.

Try this: for a whole day, forget about the clock. Eat when you’re hungry and sleep when you’re tired. What do you think will happen?
You may be surprised to find that your day is much like most other days. You’ll probably get hungry when you normally eat and tired when you normally sleep. Even though you don’t know what time it is, your body does.
Inside our bodies are several clocklike systems that follow a 24- hour cycle. Everyone is unique, which is why you might like to stay up late while your sister always wants to go to bed early.
Regularly staying up late can make kids do worse on tests and quizzes. And working shifts at night leads to higher rates of heart disease.
“There is a growing sense that when we eat and when we sleep are important parts of how healthy we are,” says Steven Shea, Director of the Sleep Disorders Research Program at Brigham and Women’s Hospital in Boston.
“During the night, we are prepared to sleep,” Shea says. “During the day, we are prepared to eat and move around, If you reverse ( 颠倒) what you are doing, everything is out of phase. That can have adverse consequences.What does the underlined sentence suggest?

Most American students have said goodbye to fancy(高级的) fruits these days. In school canteens across the country, cheaper fruits like apples and oranges have taken their places.
“People are afraid to spend now,” said Linda Morrow, who owns a shoe and handbag store. “They don’t know what the future will bring.”
During the financial crisis(金融危机), several of the country’s biggest banks have been forced to sell or close. This has made lots of Americans afraid to buy expensive goods.
Samira Marino, a restaurant owner in Miami, has found everyone is ordering water instead of juice and more people are sharing meals. In more than two dozen interviews with The Associated Press across the country last month, Americans talked about their concerns, from worries about small businesses to doubts about simply making ends meet.
The crisis began last year. Experts think it was because US banks lend money too easily. Last year a lot of people and companies, who borrowed money, have found themselves unable to pay it back. This left the banks, as well as the people who put their money in the banks, without money. Since the banks borrowed money between themselves and even across borders(国界), the whole world was in trouble.
This month the US government agreed on a $700 billion plan to try to save the financial market. But no one is sure whether it will help or not. President George W. Bush has warned it will take some time.
Last week top finance officials from 20 countries promised to work together to find a way out of the money trouble.Why are people in the US afraid to spend?
A.Because they think it’s unnecessary. |
B.Because they don’t have the habit of spending money. |
C.Because they worry about their future. |
D.Because they don’t have enough money. |
The fifth paragraph mainly _________.
A.tells what it is like in a crisis |
B.explains why there is a crisis |
C.warns people of the danger of the crisis |
D.asks people not to borrow money from banks |
People feel ______ about the US plan to save the market.
A.satisfied | B.doubtful | C.hopeless | D.angry |
The best title for the story is ________.
A.Ways to make ends meet |
B.The money problem facing the world |
C.Healthy fancy fruits |
D.The art of borrowing |
Brownie and Spotty were neighbor dogs. They loved each other and played together so often that they had worn a path through the grass of the field between their houses.
One evening, Brownie’s family noticed that their dog hadn’t returned home. They went looking for him, but with no success. Brownie didn’t show up the next day, and by the next week he was still missing.
Curiously, Spotty showed up at Brownie’s house alone. He barked loudly. But busy with their own lives, Brownie’s family just ignored (忽略) their neighbor’s nervous little dog.
Finally, one morning Spotty refused to take “no” for an answer. He followed Ted, Brownie’s owner, everywhere he went. He barked, then rushed towards a nearby empty lot and back, as if to say, “ Follow me!”
Finally, Ted followed the dog across the empty lot. The dog led the man to a tree a half-mile from the house. There Ted found Brownie alive. One of his legs was crushed (夹住) in a trap. Ted wished he had taken Spotty’s earlier appeals (求助) seriously.
