Artificial intelligence(AI)(人工智能)is the ability of a computer program or a machine.The computer or the machine with AI can think and learn. It is also a field of study that tries to make computers "smart". John McCarthy, a scientist, came up with(提出)the name "artificial intelligence" over 60 years ago. Many things such as learning and problem solving can be done by computers, though not in the same way as people do.
An unusual goal of AI research is to create computer programs.They can learn, solve problems, and think logically(逻辑地). At present, Al can successfully understanding human speech, recognizie (识别)human faces, operate self-driving cars and compete in some game systems like playing Chess. However,Some people also consider(认为)AI a danger to humans if it develops too quickly. A famous British scientist also was not for this kind of technology.
Math is the basic language of AI. If students are good at math, they will be more likely to become successful AI designers(设计者)in the future. We need not only bright students, but also average(普通的)students.As for(对于)average students ,if they get enough math skills,they can also become successful AI designers. Besides, a good knowledge of computer science is also necessary for AI designing.
Scientists hope to create creative(有创造力)and emotional (有感情的)AI. The AI can possibly understand human feelings or create art. Many ways and tools have been tried to discover this wide and exciting field.

【推荐1】Mr. Green made a robot. He could say only one sentence “There is no doubt(疑问)about it.” The robot always repeated these words when you spoke to him.
One day, Mr. Green needed lots of money and he took the robot to the market to sell him. “Who will buy my robot? He is very clever,” he shouted, “Twenty thousand dollars for my robot!”
A man was surprised that he was asking for so much money. Instead of asking Mr. Green why he wanted so much money, he decided to speak to the robot. “Are you worth(值)twenty thousand dollars?” he asked the robot. “There is no double about it.” answered the robot.
The man liked the robot’s answer so much that he bought him and carried him home. But very soon he found that the robot could say nothing else. He was sorry he bought the robot. He stood in front of the robot and said, “How foolish I was to throw so much money away!”

【推荐2】What would the world be like if cars could drive themselves? Imagine seeing an empty car passing by on its way to pick up its owner, or a car full of passengers who are reading, listening to music or even sleeping, but none of them is worried about the road ahead.
Well, all of this could be the future of driving. There are several companies, including Google, working on driverless cars. So far, no Google self-driven car has gotten a traffic ticket, but some of them have been in accidents when other cars hit them.
These cars are now still in the testing stages. But, if the tests are successful, these electric self-driven cars could be put into use very soon.
The cars already have many features (特点) allowing them to take the place of drivers during certain situations. Some features include cars being able to park themselves, or slow down when they notice objects close by. They can also control the speed if there are dangerous conditions. Scientists and engineers believe, with the help of wireless (无线的) signals, cameras and GPS, we are now at a stage where creating a safe self-driven car might be possible.
The cause of deadly road accidents is usually careless drivers or dangerous conditions. The self-driven car may be able to prevent these. However, some people don't like the idea. American lawyer White Drake, for example, does not believe these cars are safe. He thinks technologies can also make mistakes.
1. The main purpose (目的) of the first paragraph is to ________.A.make readers wonder about self-driven cars |
B.get readers to pay attention to road safety |

【推荐3】Is your schoolbag too heavy to carry? The e-schoolbag will help you. It is said that e-schoolbags are going to be brought into use in Chinese high schools soon. In fact, the e-schoolbag should perhaps be called an e-textbook. It is a small computer for students. Heavy schoolbags have long been a serious problem for them. But the e-schoolbag will change everything. It is much lighter than a usual schoolbag. Also it is as small as a usual book, but it can still hold all the things for study, such as a textbook, an exercise book and so on. They can be made into chips that are as small as stamp. The students can read the text page by page on the screen, take notes, or even send emails to their teachers. All they have to do is to put the right clip into the e-schoolbag and press a button.
Some say that e-textbooks can be easily broken; some say it is not good to students’ eyes. But only time will tell.

【推荐2】Yesterday, my 15-year-old brother Tommy had a fight with my 12-year-old brother Kevin. I didn’t notice.
Later, as I was walking upstairs I heard Kevin crying in his room. I knocked on the door and asked, “Kevin, do you want to talk?”
No one answers. I tried again. Still nothing happened.
So, I took some cards and wrote, “If you don’t, we can write notes.”
An hour later I was still sitting on the floor outside his door with two pieces of paper in my hands. One piece new and the other was from Kevin. As I read one of Kevin’s notes, tears came to my eyes. It says, “Nobody in this family cares about me. Tommy thought I was too weak and Dad told me he wished he had the other Kevin as a kid because he’s better at basketball. You’re never around to even notice me.”
He was right about my part. I wrote back, “Kevin, I do love you and you know that. I’m here for you and you are loved in this family.”
He didn’t reply for a while, but then I heard he cried a little bit. Kevin ran out of rooms and wrote “Thanks” on a paper cup. I wrote back “For what?” It returned to me with “Loving me” on it.
Since then, I have tried my best to pay more attention to my family members. Kevin and I have a closer relationship now and when one of us notices that the other is unhappy, we’ll smile and say, “Write it on a paper cup.”

Carrier pigeons can be trained to carry messages to people. The note is placed into a small can. The can is tied to the pigeon’s leg. Then the pigeon flies off with the note.
Lifeguard
From high up in the sky, specially trained pigeons can find orange life jackets in the ocean. Sometimes it is difficult for humans to find people lost at sea, especially when the weather is bad. However, pigeons can fly quickly over a large area of water to look for people.
Spy
Many years ago, carrier pigeons were used to help our country during wars (战争). “Spy pigeons” had small cameras that were tied to their feet. As a pigeon flew over enemy (敌人)land, the camera took photos of the land below. This would allow our soldiers to see where the enemies were and what they were doing.

In 1987, a small company named Huawei was started in Shenzhen. After more than 30 years of development, the company has now beaten Apple and become the world’s second-largest maker of smartphones behind Korea’s Samsung. It has also become the world’s largest supplier(供应商) of 5G.
But recently, Huawei faced some difficulties. The U.S. government ordered a ban(禁令) on its sales in America. American officials said Huawei gave information that it collected to the Chinese government. At the same time, the U. S. government planned to stop selling parts and services to Huawei, which was believed that Huawei’s business would be hurt.
“We have never received such a request from the Chinese government and we have never tried to get into other systems to collect information.” Ren Zhengfei, Huawei’s founder and president said. “This ban from the U.S. would have little effect on our company. Huawei has enough ability to deal with the problems.” Ren added.
In an interview several years ago, Ren Zhengfei said, “I started Huawei with only
£4,000 at the beginning, but now it has become a $100 billion company. The experience was not as romantic as you imagine.”
Facing the ban of the U.S., Huawei is growing. Huawei’s smartphone sales around the world rose 50 percent compared to a year earlier in the first three months of 2019. At the same time, sales from both Samsung and Apple fell. So far, Huawei has grown into the world’s largest telecommunications equipment( 电信设备) supplier, selling in 170 countries!

Have you ever heard of Weifang, Shangdong Province? What is it known for? There is an international kite festival every April in Weifang that is a modern city with many traditions. People from all over the world compete in the kite flying. There are also competitions for the best kites. The kites in the competition are all made by hand.
Most people have flown a kite. It makes people happy. It’s easy to make it. It’s made of bamboo and paper. But not so many people know that kites were first made in China thousands of years ago. The ancient Chinese made and flew kites even before they could write.
A long time ago, the Chinese made kites to use in wars. They would fly these war kites in the dark. The kites were fixed and they made strange sounds in wind. Men who were at war against them would hear these sounds and run away. They thought those strange sounds were made by gods in the sky.
The ancient Chinese also flew kites to bring good luck and to make their crops grow rich and tall. Sometimes they tied long strings and hooks (钩子) to their kites. Then they would fly the kites over water, letting the hooks hang down to catch fish.
The Chinese use sticks, string (线) and paper for their kites. Some of these kites look like animals or trees and others look like houses.

When it comes to daily choices, we already have a lot of tasty plant “milks” to choose from, but the latest one, potato milk, is a new one. Potato milk doesn’t sound like the most delicious thing in the world, neither does oat milk (燕麦奶).
If you hope to try potato milk, you’ll be happy to know that you can make it yourself at home. Generally, you just boil the potato, then mix it with the water it is boiled in, strain (过滤) it and add more water until it is what you want.
The only welcome potato milk, recently has been firstly sold on the market. Although some people noticed the potato milk when it was sold, the success of this “milk” still needs time, as some people who have tried it said that it tasted so so, others thought that it tasted a little salty.
But growing potatoes needs less land than growing oats, and it requires little water. Also it has more production than most plants. The new healthy drink may have a huge hill to climb, but it certainly has a chance to become the next big thing.
1. Potato milk is a kind of new plant milk.2. People can’t make potato milk at home.
3. The success of potato milk doesn’t need time.
4. Potato milk may not taste good to some people.
5. The production of potatoes is less than that of most plants.
England Certain symbolic objects are mixed into the birthday cake as it’s being prepared. If your piece of cake has a coin in it, then you will be rich. Also, when it’s your birthday, your friends give you the “bumps”. They lift you in the air by your hands and feet and raise you up and down to the floor; one for each year you lived, then another one or two for luck. |
Denmark A flag is flown outside a window to show that someone who lives in that house is having a birthday. Presents are placed around the child’s bed while he/she is sleeping, so he/she will see them at once upon awakening. |
Holland Special year birthdays such as 5, 10, 15, 20, 21 are called “crown” years. The birthday child receives an especially large gift on a crown year birthday. The family also decorates the birthday child’s chair at the dining room table with flowers, paper streamers and balloons. |
Canada The birthday child’s nose is greased (涂抹) with butter for good luck. The greased nose makes the child too slippery for bad luck to catch him/her. In some parts of Canada, the birthday person even receives a punch (一拳) for each year he/she is alive and then one for good luck. |
Brazil The birthday child receives a pull on the ear for each year he/she has been alive. The birthday person also gives the first piece of cake to his/her most special friend or relative, usually mom or dad. |

【推荐2】Every person has its own way of saying things, its own special expressions. Many everyday American expressions are based on colors.
Red is a hot color. Americans often use it to express heat. They may say they are red hot about something unfair. When they are red hot they are very angry about something. The small hot tasting peppers found in many Mexican foods are called red hots for their color and their fiery taste. Fast loud music is popular with many people. They may say the music is red hot, especially the kind called Dixieland jazz.
Pink is a lighter kind of red. People sometimes say they are in the pink when they are in good health. The expression was first used in America at the beginning of the twentieth century. It probably comes from the fact that many babies are born with a nice pink color that shows that they are in good health.
The color green is natural for trees and grass. But it is an unnatural color for humans. A person who has a sick feeling stomach may say she feels a little green. A passenger on a boat who is feeling very sick from high waves may look very green.
Sometimes a person may be upset because he does not have something as nice as a friend has, like a fast new car. That person may say he is green with envy(羡慕、嫉妒). Some people are green with envy because a friend has more dollars or greenbacks. Dollars are called greenbacks because that is the color of the back side of the paper money.
The color black is often used in expressions. People describe a day in which everything goes wrong as a black day. The date of a major tragedy is remembered as a black day. A blacklist(黑名单) is illegal(违法的) now. But at one time, some businesses refused to employ(雇用) people who were on a blacklist for belonging to unpopular organizations.
In some cases, colors describe a situation. A brown out is an expression for a reduction(缩减) in electric power. Brown outs happen when there is too much demand(需求) for electricity. The electric system is unable to offer all the power needed in an area. Brown outs are common during World War Two. Officials would order all lights in a city turned off to make it difficult for enemy planes to find a target(目标) in the dark of night.
