With intelligence systems and New Age networks, life in the big cities will likely be happier and more efficient (有效率的). After all, more than 60 percent of the world’s population is expected to live in cities by 2050, according to a UN report. The answer to making these cities more livable for so many people lies in creating “smart” cities. They will use 5G networks and the Internet of Things (LOT) to make everyday life safer and more convenient. Some cities are already using smart technology to improve the lives of their people.

But what exactly does a smart city do? Let’s s look at a few examples. In United States cities of Boston and Baltimore, sensors (传感器) in smart rubbish cans can tell cleaning workers how full they are and when they need to be emptied. In Amsterdam, the Netherlands, traffic flow and energy usage are kept track of and adjusted (调节) according to real-time data collected from sensors around the city. And in Copenhagen, Denmark, a smart bike system allows riders to check on air quality and traffic jams as they ride.

Smart cities will be interactive (互动的), allowing their people to fed like they’re truly shaping their environment, instead of only living in it. It’s very important that we can actually communicate with our environment in a way that we never had in the past. Smart cities will also allow us to save resources. By using sensors and 5G networks to watch over the use of water, gas and electricity, city managers can figure out how to share and save these resources more efficiently.

Of course, it will take time and money to turn our present cities into the smart cities of the future. But as we’ve already seen, more cities around the world are already using smart technology in small ways. It won’t be long before more cities start to develop their own smart systems.

1. What makes it necessary to create smart cities?
A.The development of present cities.
B.The increasing population in cities.
C.The wide use of 5G networks and IOT.
D.The growing number of present cities.
2. How do smart rubbish cans help?
A.By adjusting the cans’ position.
B.By keeping track of the air quality.
C.By emptying the rubbish by themselves.
D.By reminding the workers to clean them.
3. What is paragraph 3 mainly about?
A.How smart cities work.
B.The future of smart cities.
C.The influence of 5G on smart cities.
D.How smart cities communicate with us.
4. What is the authors attitude to smart cities?
A.Supportive.B.Worried.
C.Uninterested.D.Doubtful.

【推荐1】“Iris scan, please,” the bank's computer voice tells you. You step up and the computer reads your eye, comparing it to the stored file it has of your iris. The images had better match—otherwise you won't be able to get your money.

Iris scanning and other technologies, such as fingerprint and voice scanning, have appeared in many science fiction movies in the past. Today, They are common at work, the bank, the airport, and your local prison. The iris scan, fingerprint scan, and voice scan are all examples of biometrics, a fast-developing area of automatic personal identification technology. Basically, biometrics uses various ways to verify a person's identity, based on the people’s unique characteristics, including fingerprints, voices, irises, body heat patterns, facial images, handprints, signatures and so on.

Iris scans currently give the highest level of accuracy among all the available biometrics systems. Another technology, full facial scans, is currently in use at border crossings and airports. Facial scanning equipment can actually track and identify moving faces within a crowd.

The potential of biometrics is exciting and encouraging. With continued development, testing and application, current technologies will become even more effective in the future. Soon, the days of password and car keys will be gone. Just don't leave home without your fingerprints!

1. The first paragraph serves as a(n) ______ .
A.exampleB.explanationC.commentD.conclusion
2. The underlined word "verify" in Paragraph 2 probably means " ______ ".
A.protectB.proveC.developD.change
3. Which is the most accurate form of biometrics?
A.The voice scan.B.The fingerprint scan.C.The iris scan.D.The facial scan.
4. What is the author's attitude towards the future of biometrics?
A.He feels hopeful about itB.He feels doubtful about it.

文章大意:本文是一篇说明文。主要介绍的是科学家们为解决宇航员在太空中的饮食问题,致力于在太空中种植农作物,这样太空中的食物种类会增加,宇航员的营养也可以得到保障。

【推荐2】Astronauts get to experience many interesting attractions. When astronauts go to space, they can become weightless. They get to see Earth as a little blue dot. Astronauts get to experience shooting up into space at 20,000 miles per hour. That is more than three times faster than an airplane. Sill, food is not one of the interesting parts of being an astronaut. Space travelers have had to eat strange foods. One example is liquid salt and pepper.

However, the menu for astronauts is going to grow. Scientists have been growing lettuce in outer space. The lettuce is just as safe, nutritious(有营养的) and tasty as lettuce grown on Earth Gioia Mass works at the NASA Kennedy Space Center in Florida. She is the lead scientist on the lettuce growing project. She said that growing food in space could be pivotal for astronauts on long missions(任务). Massa says that today’s space food may not work for these longer missions. This packaged food is stored for a long time. The quality and taste of the food goes down. In addition, the vitamins in the food start to breakdown. Massa says the astronauts may not get enough nutrition from these foods during long missions.

She also added that there could be another benefit to growing food in space. Looking after plants could help astronauts emotionally. Space food has improved in recent years. Many astronauts visit the International Space Station (ISS). It is a research station in outer space. Anything sent to ISS has to be perfect on a taste test. Even so, astronauts can grow tired of eating the same old meals. Massa says many of the astronauts end up losing weight.

The space-grown lettuce was similar to Earth-grown lettuce. In fact, some of the space-grown plants had more nutrients than Earth-grown lettuce. The space lettuce also had higher levels of bacteria(细菌). This was possibly because the lettuce grew in a warmer, more humid system. However, none of this bacteria was dangerous.

1. Why does the author mention some strange foods space travelers have had to eat?
A.To draw a conclusion.B.To prove an idea.
C.To introduce the topic.D.To give explanations.
2. What does the underlined word “pivotal” probably mean in the second paragraph?
A.Important.B.Unbelievable.
C.Adventurous.D.Impossible.
3. Which of the following may Massa agree with?
A.Astronauts get little nutrition from growing food in space.
B.Growing food in space gives astronauts a more varied diet.
C.Astronauts get help physically by looking after plants in space.
D.Astronauts never grow tired of eating the same old packaged food.
4. What may happen in the following days according to the text?
A.NASA will grow other produce on the ISS.
B.More and more astronauts will end up losing weight.
C.Astronauts will stop their missions and tum to growing space food.
D.More Earth-grown food will be sent to ISS to keep astronauts from getting sick.

文章大意:本文是说明文。文章主要介绍OpenAI宣布可能很快开始提供付费版本的ChatGPT人工智能聊天机器人。

【推荐3】If you have tried chatting with ChatGPT lately, you have probably been met with an “at capacity” error message at some point. The chatbot’s sudden huge popularity can make accessing the service pretty tricky. And while it’s fun to chat with the AI or even get it to write essays or take exams, some people want guaranteed access so they can use the chatbot for professional purposes.

Earlier this month, OpenAI announced that it may soon start offering a paid-for version of ChatGPT with an option called ChatGPT Professional. A waitlist that OpenAI posted to the server detailed what pro users might expect.

The professional offering, which OpenAI described as “experimental”, will be “always available,” offer “fast responses from ChatGPT,” and would provide “as many messages as you need.” The waitlist also noted that, if selected, OpenAI would reach out to you individually to set up a payment process and a pilot.

Now it seems like OpenAI has picked its early access users and they are sharing some insights. Zahid Khawaja, an early access user, shared a video on Twitter running a test prompt on the pro version that ran much quicker than the free version the rest of the public has access to. In the video, Khawaja showed his subscription cost, which comes in at $ 42 a month.

How OpenAI decided on $ 42 a month is yet to be revealed-perhaps it’s yet another Hitchhiker’s Guide to the Galaxy reference. However, in December Sam Altman, OpenAl’s chief executive said the average cost of each response was in “single-digits cents”, but he admitted it will need to charge the service eventually because of its “eye-watering“ compute costs. A recent agreement with Microsoft, which will see the software giant invest billions in OpenAI over the next few years, will also likely help.

Despite its popularity, ChatGPT isn’t the only AI chatbot on the market. The $ 42 a month price tag is causing some users to seek other alternatives that might be more cost effective and just as efficient.

1. What does the author think of having access to the service?
A.Not easy.B.Not good.
C.Not tough.D.Not slow.
2. Which of the following isn’t provided in the professional version of ChatGPT?
A.All-time availability.
B.Enough information.
C.Free subscription.
D.Faster response.
3. Why was the service charged in the end?
A.It is to be revealed next month.
B.It is customers’ requirements.
C.It needs Microsoft’s investment.
D.It needs very high running costs.
4. What can be inferred from the last paragraph?
A.ChatGPT charges the lowest on the market.
B.ChatGPT will lose most of its access users.
C.ChatGPT may lose some targeted customers.
D.ChatGPT is more effective and efficient.
