Someday in the future we may not need to have money in our pockets. Is life easier when people don’t need to carry any money? Maybe in the future each of us will have only one small credit card. We will use it instead of money to buy all the things.
Of course we may still have some of the same problems with cards we now have with money. For example, we lose money from time to time. Maybe we will lose the cards. Maybe someone will take the cards. Someone may even make a card that looks like our cards. Since we can’t buy anything without our cards, the credit cards may be no better than money.
Is there something easier to use than credit cards? Each of us has a thumbprint(拇指指纹). No two thumbprints are the same. Maybe someday the government will keep people’s thumbprints with a number. When you want to buy something, you will put your thumb on a machine or a computer. Each store will posses one. Everyone’s thumbprints will be in the computer. It will be difficult to lose our thumbprints! It will be difficult for someone to steal it or to make one like it.

【推荐1】Can’t find any place on Earth for your next holiday? Lucky for you, Space tourism is no longer a thing of science fiction. A Californian company is going to offer you a chance to take a vacation in space by building a hotel in orbit (轨道).
The Orbital Assembly Corporation plans to build Voyager Station, a space hotel that includes rooms for tourists, in 2026, and open it in 2027. It will be able to carry up to 400 people.
The space hotel will be shaped like a large wheel, with 24 space pods (舱) around the outside of the 200-meter-wide structure. Each pod is 24 meters long and 12 meters wide. The pods will be used for restaurants, bars, gyms, rooms for tourists, laboratories for research and so on.
The company says that some pods will even be private homes that people can buy. “Finally, going to space will just be another choice for people’s vacation, just like going on a cruise, or going to Disney World,” said Tim Alatorre, senior architect (建筑师) of the space hotel. He said that the space hotel may even include a concert hall and a movie theater.
The company says that the space hotel will have gravity (重力) that is about one-sixth as strong as Earth’s. The low gravity means people can do things like jump higher, lift heavier things and enjoy sports such as basketball in a new way.
With the industry rapidly developing, space tourism for common people is around the corner, and it might come much faster than we think. Who knows what the future might be like?

Chat GPT is a kind of a new robot that was trained by Open AI company in San Francisco. It is able to understand the human languages and communicate with human beings as well. By having dialogues with people, it is possible for Chat GPT to answer questions, realize its mistakes, challenge incorrect settings, and refuse some requests that are not very suitable.
GPT is short for Generative Pre-trained Transformer (生成型预训练变换模型). Its producer Elon Musk says, “Chat GPT is scary good. We are not far from dangerously strong AI.” It has reached 100 million users in just two months after coming out, according to the experts.
Chat GPT is a good talker and listener. It can become serious or humorous in different situations. For example, one says, “Tell me a lie.” Chat GPT answers, “The sky is made of green cheese.” Then he says, “That’s a bad lie. Tell me more lies.” Then Chat GPT says, “I am a human being.”
Besides communicating, this AI chatbot (聊天机器人) can also write e-mails and papers. It is unbelievable that it is good at creating poems and stories. GPT technology can even help people write code (密码) quickly and correctly. Maybe one day, it can work as a level three engineer.
However, some experts tell that Chat GPT may not be able to answer questions that are outside of its training data (数据). Chat GPT doesn’t change our lives completely, but it proves that the artificial intelligence (人工智能) has developed into a new stage. Do you think Chat GPT will take place of human beings?

【推荐3】The company Open AI introduced ChatGPT to the world. It is the latest kind of AI chatbots. Anyone can use ChatGPT for free now so that the company can collect (收集) people’s ideas on how to improve it.
ChatGPT is able to write articles for newspapers. And when teachers ask it to write answers to exam questions, ChatGPT can almost get full marks. In our everyday life, it can help a father come up with ideas of a birthday party for his son. It is also able to solve difficult coding (编程) challenges (挑战) and answer very quickly.
What’s more, when people ask ChatGPT questions, it can find mistakes. If somebody asks what happened when Columbus arrived in America in 2023, ChatGPT can point out that Columbus reached America in the 1400s, not in 2023. It can also refuse to answer some questions. For example, if you ask it for advice on stealing a car, it will say that stealing a car can have bad results. Instead, it gives advice such as “taking the bus”.
ChatGPT might help people solve problems, but AI must use texts (文档) from the Internet. Often, the texts are used without being allowed (允许) by the writers of those texts, and sometimes the writers wouldn’t like to share their texts with others at all. So some people think that AI is bad for the human.
However, like it or not, AI is here. Maybe working on it well is the best way out.

Scientists have found out that radiation(辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of radiation from the sun and other stars, which is bad for their health. Some special medicine may work a little, but there’s no really helpful medicine.
Space junk is also thought a great danger to spacemen. It’s reported that there are 9,000 man-made things flying in space. About 30% of these are man-made satellites(卫星),10% are spaceships, and the rest are space junk. An explosion(爆炸) in 1996 made a cloud of 300,000 fragments(碎片), each at least 4 mm in size, and even a small piece of these knocked against a spaceship window and did some damage. Scientists are working on helpful ways to do with space junk.
Although space is really dangerous, it interests everyone on the earth. In the near future, it may become usual for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space for a few years. So we should care for space and do something to help improve the space environment.

【推荐2】5G technology would be widely used by 2020, causing some experts to say the “5G epoch” is coming. Yet, when reporting about 5G, many reporters only described it as a “much faster” technology than 4G. As a result, what people know about 5G is that they could “download a movie within one second”.
Actually, 5G technology has many more advantages than 4G besides the speed. It can be used for at least two purposes—for connecting everything and removing delays (消除网络延时).
Connecting everything is one of the strongest functions of 5G. It makes the Internet Things possible. Take driverless smart cars as an example. 5G technology can connect all parts of a transportation system including traffic lights, CCTV cameras and cars to build up perfect coordination (协调). In this way, these cars can avoid obstacles (障碍) and move on driving routes, which will help improve self-driving technology. And removing delays might be useful especially in online games. Factories can produce more macro base stations to allow more people to use. The more users, the lower cost. Therefore, 5G technology won’t cost as much as they thought.
1. The underlined word “epoch” in Para 1 means ________.| A．technology | B．age |
| C．equipment | D．sign |
| A．it makes the self-driving car run much faster. |
| B．it helps to connect the cars with the Internet |
| C．it helps the cars avoid obstacles and move on driving routes |
| D．it helps the cars control the traffic lights and CCTV cameras |
| A．people can pay less for 5G | B．5G can be compared with 4G |
| C．the “5G epoch” can come sooner | D．few people can enjoy the 5G technology |
| A．people know a lot about 5G |
| B．5G is much faster but more expensive than 4G |
| C．connecting everything is the strongest function of 5G |
| D．online game players can enjoy continuous high speed of 5G |
| A．The “5G Epoch” is coming. | B．The latest 5G products have been invented. |
| C．5G costs less with higher speed. | D．5G is more than about high speed. |
The construction（建设）of high-speed railways in China began with the building of the Qinhuangdao-Shenyang High-Speed Railway（HSR）in 1999. Now the high-speed rail network in China is the largest in the world. So far, there have been about 1,700 kilometers of HSR in service, along with trains of an average（平均）speed of 220 km/h.
Now Chinese government plans to spend $300 million building the largest and fastest HSR system in the world by 2022. It’s said that the trains can run 400 km/h and create new business for China and other countries through the Belt and Road.
It’s predicted that the HSR network in China will reach 30,000 kilometers and it will be like a grid, which is mainly made up of 8 long-distance high-speed rail lines: four north-south HSR lines and four east-west HSR lines. Except（除了）for the Qingdao-Taiyuan HSR, all HSR lines of the rail grid are longer than 1,000 kilometers.
Feng Hao, an expert, says “Many markets along the Belt and Road, especially in Central Asia, Southeast Asia, the Middle East and Eastern European countries, are planning to build HSR lines.”
1. China is going to build the largest and fastest HSR system in the world by ________.| A．2020 | B．2021 | C．2022 |
