=If you look at the top of your phone，you'll usually 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 5G fully arrives．
On March 30th，2019，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．
Now，4G takes about 100 to 200 milliseconds（毫秒）to send and receive data（数据）．But 5G will get it down to 1 millisecond or less．This big change will not only make our mobile Internet faster．It can be used in many other ways as well．
For example，5G will help to make self﹣driving cars safer．Today's self﹣driving test cars have one problem﹣ lag．When the car"sees"an obstacle（障碍物），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（撞击）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 under 5G，your refrigerator could automatically（自动地）place an order online for eggs when it finds that there are no eggs left inside．
All in all，5G will shape every type of technology that it touches．And you won't have to wait too long for that to happen．

Mr. Smith was in trouble those days. He drove a car for Mr. Black, a rich businessman. He worked hard and the shopkeeper liked him. But he couldn't work when he drank too much.

Mr. Smith had a big family and was afraid of it and promised he would stop drinking at once. The man told him to wait to be dealt with.
One Monday morning Mr. Smith came into the office with two badly burnt ears. "What happened to your ears?" asked Mr. Black.
"Well, "said the man," I went to watch a football match yesterday while my wife was ironing （熨）clothes. She had put the iron near the telephone before she went to cook supper.

Many daily American expressions are based (以……为基础) on colours.
Red is a hot colour. Americans often use it to represent heat. When they say “red-hot”, that means they are very angry about something. Loud music is popular with many people. Some may say that such music is red-hot.
Pink is a lighter kind of red. People sometimes say “I’m in the pink” when they are in good health. The expression was first used in America at the beginning of the 20th century. It probably comes from the fact that many babies are born with a nice pink colour that shows that they are in good health.
Blue is a cool colour. The old Blues music in the United States is the opposite of red-hot music. Blues is slow and sad. Someone who is “blue” is very sad.
The colour green is natural for trees and grass. But it is an unnatural colour for humans. A person who has an upset stomach may say “I’m feeling a bit green”. A person on a boat who is feeling very sick from high waves can be said “look very green”. Sometimes a person may be very jealous because he does not have anything as nice as someone has, like a fast new car. That person may say “I’m green with envy”. Some people are green with envy because someone has more dollars or “greenbacks”. Dollars are called greenbacks in American slangs because that is the colour of the bottom of their bank notes.
The colour black is used often in expressions. People may say “it’s a black day” when everything goes wrong on that day.
In some cases, colours describe a situation. Blackouts were common during the World War II. All the lights in a city were turned off at night to make it difficult for enemy planes to find their aims in the dark.

If the rose can be said to be a special flower, then the apple can be said to be a special fruit. It is very important in American culture. American stories speak of Johnny Appleseed, who went throughout America collecting apple seeds and planting apple trees. He had a great love for nature and went through fields and farms adding richness and beauty to the country.
One of the first sayings taught to school children is, “An apple a day keeps the doctor away.” This short saying encourages children to eat fresh fruit to keep healthy. If someone always says good words to a person, people will call him an “apple polisher”. This, however, is not a good name. If someone is very dear to us, we say that he or she is the “apple of our eye”.
Most people believe that the fruit which Eve gave to Adam was an apple, even though the Bible(圣经) never says so. The apple, therefore, is a deep part of the language and stories of America.
An apple is also delicious. Apples can be cooked in many ways, used as a dessert, and made into sweet juice.
In many parts of the country during the harvest season, a popular activity is to go into an apple garden to pick apples. Washington, D. C. and New York are both famous for their apples.
Finally, when it’s time to take a vacation to American cities, one can always visit New York, which is “the biggest apple” of all the American cities.

Last summer I went through a training program and became a literacy(识字) volunteer. When I began to know what other people’s lives were like because they could not read, I realized the true importance of reading.
My first student Marie was a 44- year-old single mother of three. In the first lesson, I found out she walked two miles to the nearest supermarket twice a week because she didn’t know which bus to take. When I told her I would get her a bus timetable, she told me it would not help because she could not read it. She said she also had difficulty once she got to the supermarket because she couldn’t always remember what she needs. Since she did not know words, she could not write out a shopping list. Also, she could only know items by sight, so if the product had a different sign, she would not know it as the product she wanted.
As we worked together, learning how to read built Marie’s self-confidence, which encouraged her to continue her studies. She began to make fast progress and was even able to take the bus to the supermarket. After this successful trip, she reported how self-confident she felt.
At the end of the program, she began helping her youngest son, Tony, a shy first grader with his reading. She sat with him before he went to sleep and together they would read bedtime stories. When his eyes became wide with excitement as she read, pride was written all over her face. As she described this experience, I was proud of myself as well. I found that helping Marie to build self-confidence was more rewarding than anything I had ever done before.
As a literacy volunteer, I learned a great deal about teaching and helping others. In fact, I may have learned more from the experience than Marie did. Marie didn’t go to the supermarket by bus because______.
| A．she lived too close to the supermarket |
| B．she wanted to stay fit through walking |
| C．there were no bus stops in front of the supermarket |
| D．she had no idea which bus to take to the supermarket |
What did the writer probably find when he was teaching Marie to read?
| A．Marie learnt how to read really fast |
| B．Marie had no gift for learning how to read |
| C．It was hard for Marie to change her habits |
| D．It was hard for Marie to build self-confidence |
We learn that in the end________.
| A．Marie could read and became confident |
| B．the writer chose to help Marie’s son to read too |
| C．the writer decided to spend more time learning to read |
| D．Marie thought she learnt more from the experience than the writer |
What is the passage mainly about?
| A．The importance of learning to read |
| B．The difficulties that a single mother faced |
| C．The writer’s most unforgettable experience |
| D．The writer’s experience as a literacy volunteer |
