Have you heard of ChatGPT nowadays 1 When asked a question, ChatGPT uses this training to produce detailed answers that often seem like they were written by a human. You can ask it anything and it will give you an answer. You can also ask it to write a text, such as short stories or plays.
Because ChatGPT is free and easy to use, learning with it seems to be easier. 2 However, with the development of ChatGPT, we know that we are getting information supported by thousands of other web pages. And the information given to us is simple and easy to understand. ChatGPT can help people who have problems in language expressions. People who don’t speak the same language can use it to exchange their thoughts and feelings. 3
But there are also some different voices. For thousands of years, students have been required to find information by using books. With ChatGPT, finding information becomes much easier than using a book. 4 Besides, it could make some people lose their jobs, as their skills are no longer needed.
5 And it’s too soon to say what kind of influence ChatGPT will have on our lives. Let’s hope that, if ChatGPT does become bigger and more popular, its effects can be mostly positive.
A．Will it be good or bad for humankind
B．In this way, it could be a great tool for bringing the world closer together.
C．It’s a type of AI that has been “trained” by looking at over 8 million web pages.
D．ChatGPT is a great example of a modern technology that is causing mixed feelings.
E．It could make cheating much easier, and make students feel their hard work is useless.
F．When we use search engines such as Baidu, we have to look at web pages one by one.
G．ChatGPT is a very useful tool among young people.

At first, e-books were just for a certain group of readers and most of them were about only a few subjects. With the development of the Internet, 7 . This is why the e-book business is rising quickly.
E-books have many advantages (优点). First of all, they save time. 8 . We can find the topic we want to know about on the Internet, and then we can quickly get many e-books on this topic. 9 . Some e-books cost us little money, and there are many thousands of e-books on the Internet. Besides, they can help to protect environment. We don’t need so many trees to make paper books. Also, e-books make reading more convenient. You can carry a whole library of hundreds of books with you in a small computer, mobile phones or any e-book reader, without worrying about their weight.
10 . They need a personal computer, a mobile phone or an e-book reader, and the information can be lost if the reader’s computer doesn’t support its file format (文件格式). However, e-books give us a new way of reading. That is really good.
A．Second, e-books save money

虚拟数字人崭露头角
Imagine you can have phone calls with your favourite star. Is it exciting AI humans might help with it. Today, AI humans are popular at home and abroad (国内外).

In February 2022, a Chinese tech company (科技公司) showed its first digital idol Xi Jiajia. 33 During China Fashion Week in September 2022, Xi Jiajia became famous in an online virtual fashion show (虚拟时装秀).
“Virtual idols could do something that people cannot do in the real world, such as time travel,” said Liu Qian. 34 They can appear to be in different places and from different times in history.
But AI humans have their disadvantages (劣势). Take Yuanxi as an example, she still doesn’t have much human touch or high EQs. 35 What’s more, virtual people can’t team up and communicate with others in real time.
As Yuanxi wrote, “Virtual employees (员工) show the power of AI but they are not a replacement (代替) for traditional human employees.”

Man has been polluting the earth from the time he first made a fire, washed his clothes in the river and threw his waste on the ground. 62 At first the problem was not so serious because there was plenty of clean air, land and water. 63 All the dirty things could be absorbed (吸收) by nature and soon be covered over. But this is no longer true. The increase of the population and the development of industry have changed that. Man is slowly polluting his environment.

In today’s digital age, social media has become an important part of our lives. 71
However, like everything else, it has its own set of problems.
One of the major issues is cyberbullying. Many users, especially teenagers, are being targeted with mean comments, threats, and even personal attacks on social media platforms. 72 This can lead to serious mental health problems such as depression and low self-esteem.

The role of teachers

AI can also provide a chance of receiving an education for those who have hearing problems or are unable to speak the local language.

Do you drink milk every day Maybe your mother wants you to drink milk every day. That’s because she thinks that milk is good for your health. But is that the truth 91

Marco Polo was born in 1254. He was a famous Italian businessman, writer and traveler. When he traveled a long way to China in 1275, he found that the Chinese used paper money. 96 Since then, Chinese paper money became known in Europe and it started to be used in Western countries. However, people in China began to use paper money in the 11th century. 97
Paper was invented in China by Cai Lun almost 2,000 years ago. 98 He then put these pieces of paper together and made them into a book.
Now paper still comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. 99 Every day, people throw away about 2,800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting nearly 48,000 trees every day.
100 We can use both sides of every piece of paper, especially when making notes. When shopping, we can take our own cloth bags or use fewer paper bags. If the shopkeepers give us a paper bag, we should save it and reuse it later.
Everyone can help to save paper. If we work together, I believe we will make a big difference.
A．So how can we save paper
B．Trees are important in our life.
C．And how could Cai Lun invent the paper
D．If there are no trees, there will be no paper.
E．He took the wood from trees and made it into paper.
F．At this time, someone may wonder when and where the paper was from.
G．During the 13th century, he introduced the idea of using paper money to Europe.
