Artificial Intelligence (AI) has been in the news a lot lately. And according to a recent report from the McKinsey Global Institute, about half of today’s work activities could be automated(自动化的) by 2055. Could “teaching” be on that list?

The teacher in the classroom is a human model. When a human teacher is able to show the advantages of learning, learners are more likely to be inspired to work harder and make progress. Even AI with advance technology can’t do this.

So, the chances are that your job is safe for the near future. But it is going to change, and robots will join us quite soon, as teaching assistants.

Recently, a Georgia Tech professor has used an AI teaching assistant in his classroom, which allows him to more effectively manage over 400 students. His AI teaching assistant helps him answer more routine questions, freeing him to deal with some complex problems which are difficult to solve from students.

AI is also being used in South Korea and Japan to help with language learning. Students can go through any variety of conversational practices, and AI can correct mistakes in usage and pronunciation. In fact, research shows that these programs can help solve problems like shyness and frustration(挫败) that can appear when children practice repetitively with a teacher. After all, a robot will not get tired or annoyed no matter how many mistakes a child makes.

This will be the future of AI in the classroom. Should you start packing up your desk? Absolutely not. The bottom line is that these technologies work best when paired with an active human teacher. But it certainly could make your job easier and more efficient.

1.What is the second paragraph mainly about?

A.The present teaching conditions.

B.The advantage of human teachers.

C.The purpose of using an AI teaching technology.

2.What does underlined word “complex” means in Chinese?

A.复杂的 B.普遍的 C.完整的

3.In what way is a robot better than a human teacher?

A.It is more patient. B.It is more creative. C.It is more convenient.

4.Who is the passage probably written for?

A.Students. B.Teachers. C.Parents.

5.Which can be the best title for the passage?

A.What will teachers be like in the future?

B.The benefit of using teaching assistants.

C.Could AI take the place of human teachers?

A company says it has completed the first 3D-printed home recently. The home was shown to reporters and visitors at a music festival.

The building company has developed large 3D- printers that build homes with mortar, a hard and strong

material.　 It　 uses　 robotics,　 computer　 programs　 and　 advanced　 materials　 to　 make houses.

Jason Ballard is the company's chief engineer. "So I'm standing in front of the first 3D-printed home in America. This house was actually printed in high winds, blowing dust and rain." It is important for the printing programmes to operate in bad weather conditions, such as weather disasters. The goal is to print homes in developing　 countries. So the printer has to be light enough to move from one property to the next.

Ballard imagines that someday, many 3D-printers will operate around the world to make homes. "It's actually a lot more simple to build a printer than it is to build a house," he said. "We ran this printer at about a quarter speed to print this house, and completed it in about 48 hours of print time."

The company developed this technology not to make money but to help provide a quick, cheap housing solution for the millions of people who need it most. There are about a billion people that don't have one of life's most basic human needs, and that's safe shelter.

Ballard says his company already works on housing needs with poor families in different areas. But he says that to really make a difference, the program will need to be greatly improved. He added that since the 3D-printing process is so much faster than traditional homebuilding, a whole community could be built in just a few months. He believes over time, people can get the new home below $4,000 with the help of 3D-printers.

1.What kind of building material can be used in 3-D printing according to the passage?

A. light but strong　　 B. light and soft.

C. strong but expensive　　 D. hard and strong.

2.What is the meaning of the underlined word　 property in Paragraph 3?

A. land for farming　　 B. land for building houses

C. land for raising animals　　 D. land for running companies

3.It will take about　　　　 hours to print a house if the printer is at its full speed.

A. 12　　 B. 24　　 C. 36　　 D. 48

4.What is the best title for this passage?

A. The Future of 3D-printing　　 B. The History of 3D-printing

C. The New Use of 3D-printing　　 D. The Instructions of 3D-printing

Do you dream of having a sister or brother？According to the recent CCTV news report，China has relaxed its one­child policy (政策) to two­child policy. The government has allowed families to have two children.

Tencent did a survey last week about the two­child policy. On the one hand，up to 53% of parents say they are willing to have a second child. “I am excited about hearing the news. To have two kids means the children can look after each other in the future. Not only can they have a partner to play with，but they can also learn to help one another. This helps them to develop a better personality. I think I won't miss the chance to own a second kid，” says Li Mei，a mother of a 5­year­old daughter from Shanghai.

On the other hand，about 40% of parents say they may not have a second child. One reason is that they are afraid that the child's everyday expenses (费用) and education would be a big problem. They couldn't afford them. “I think the policy itself is pretty good，but I don't think it interests me. I won't consider a second child. Everything is very expensive at present，and I find it very difficult to raise another child，” says Han Dong from Chongqing，who has just had a boy.

Though people have different opinions，they agree that China has made great progress already in the two­child policy.

1.China has relaxed its two­child policy to one­child policy.

2.According the survey, up to 53% of parents say they are willing to have a second child.

3.According to the passage, we know Li Mei has a son.

4.Some people may not have a second child because they couldn’t afford the child’s everyday expenses.

5.Han Dong doesn’t want to have a second child.

Violence (暴力) at schools has been widely reported in recent years. Hitting, slapping (打耳光) and burning others with cigarettes－the violence among teenagers has drawn public and government attention. On Nov 11, the government published a guideline (指导意见) on dealing with school violence.

The guideline stressed that students with serious behaviour problems should be taken to special schools. Or, in more serious cases, they may take criminal responsibility (刑事责任) and be sent to prison.

China has long been considered as too soft on teen offenders (犯事者), according to the People website. Criminal responsibility begins at the age of 14. Offenders under the age of 16 do not face serious punishment unless they do eight types of “serious” crimes such as murder.

This might partly explain why junior middle school students are the most common offenders in school violence cases. It’s reported that they take up 33.96 percent of the total while high school students take up 22.64 percent.

“What also shocked us is how cruel (残忍的) some young offenders can be,” said Shi Weizhong.

In school violence cases in Beijing during the last five years, 14 percent of the offenders not only beat others, but also insulted (侮辱) them. They slapped others, made them kneel down (下跪), and in some cases took off other people’s clothes.

“The common tolerant (容忍的) attitude toward violence should be changed,” wrote Jiaxing Daily. “When teenagers do something wrong, we should tolerate and help them when necessary. But all of this has a limit.”

1.What is the guideline about?

A. How to deal with school violence.　　 B. How students improve in studies.

C. How students get along with each other.　　 D. How to make students behave well.

2.Who should be criminally responsible?

A. An 11-year-old.　　 B. A 12-year-old.

C. A 13-year-old.　　 D. A 14-year-old.

3.Junior middle school students are the most common offenders in school violence cases possibly because ____.

A. there are not many special schools in China

B. China has been too soft on teen offenders

C. teachers in junior middle schools are not strict with them

D. they know less on laws than high school students do

4.What does the underlined word “shocked” mean in Paragraph 5?

A. excited　　 B. interested　　 C. pleased　　 D. surprised

5.Which of the following is Jiaxing Daily’s opinion?

A. We’d better patiently teach young offenders.

B. Young people need to learn to be tolerant.

C. We should tolerate school violence but there is a limit.

D. Teenagers should not do anything wrong.

We have heard about people who have special memories. Recently there has been a report about a woman from Australia who can remember almost every detail (细节) of all the events in her daily life.

However,　 sometimes her memories prove (证明) to be painful. Because they're not just events that she remembers. "When I relive （再体验) memories, the feelings return, too,” Rebecca said. "For example, I remember falling over when I was three at my grandparents' house and hurting my left knee. Talking about it now, I feel painful in my left knee. "

As far as I am concerned, most of people just twitter everything to get other’s attention. 2. Several days ago, one of my friends invited me to have dinner with her in a newly opened restaurant. It’s so hard to get a reservation so the minute we sat at the table, we couldn’t wait to order all the specials here. Soon our dinner was ready. 3. The reason is that she needed to take a photo of each dish and post it. After about five minutes, I was finally allowed to eat. But some of the dishes had become cold and lost its original flavors.

Besides, twitter is a just way to help us enjoy the life better but not a way to make up our life. 5. They try to post all the good sides of a matter, leading others to ignore the hidden things. As a result, people need to know how to tell the differences between the truth and lies.
