Welcome to your future life.

You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people of your age could live to 150, so, at 40, you aren't old at all. And your parents just had an anti-aging(抗衰老)treatment.Now,all three of you look the same age.

You say to your shirt, “Turn red.” It changes from blue to red. In 2035,“smart clothes” contain particles(粒子) much smaller than the cells(细胞)in your body. They can be programmed to change your clothes' color or pattern.

You walk into the kitchen. You pick up the milk from the fridge, but a voice says, “You shouldn't drink that!” Your fridge has read the smart chip(芯片)that contains information about the milk, and it knows the milk is old. In 2035,every article of food in the grocery store has such a chip.

It's time to go to work. In 2035, cars drive themselves. Just tell your “smart car" where to go. On the way, you can call a friend using your jacket sleeves. Such"smart technology" is all around you.

So will all these things come true?"For new technology to come early,"says scientist Andrew Zolli,“much has to be done so that new things will replace what we have today."The Internet is an example-what will be the next?

1. What is the theme of the text?
A.The Internet.B.The future life.
C.The anti-aging technology.D.The ways of transportation.
2. What does the underlined word"They" in Paragraph 3 mean?
A.Clothes.B.Cells.C.Colors.D.Particles.
3. Which of the following is TRUE about the "smart car"?
A.It can change its color.B.It can tell you where to go.
C.You can, just tell it where to go.D.You can call your friend to drive it for you.
4. What does the last paragraph tell us?
A.Nothing is impossible.
B.Every coin has two·sides.
C.Where there is a will, there is a way.
D.Never count the chicken before they are hatched(孵化)。
5. In which section of a newspaper can you probably read the text?

文章大意:本文是一篇说明文。主要介绍了几种解决道路安全问题的新科学技术。

【推荐1】New Science and Technology


Look carefully before you cross

The city of Daye in Hubei Province is using new technology to stop people from crossing against red lights. The city has set up special posts (杆) on its sidewalks. The posts can recognize (识别) human faces. If they catch a person crossing at a red light, they will send water drops at him or her.


High-tech building

China not only builds things quickly, but also tries to use new and high technology. About twelve years has passed since the opening of the Qinghai-Tibet Railway. About 550 kilometers of the railroad runs over ice-covered earth. When the ice-covered earth gets warm during summer, it can make the railway move. Chinese scientists built special structures(结构) to solve this problem.


Musical road in Holland(荷兰)

In a village of Holland, there is a musical road. With the help of something special, the road can play a song. But if a car drives at a speed of over 60 km/h, the sound will become noisy. The local government thinks it will encourage drivers to control the speed. They will have to slow down in order to hear the song instead of the noise.

1. If you cross the street at a red light in Daye, you will be punished_________.
A.by other peopleB.by red lights
C.by the policemanD.by water drops
2. Chinese scientists built special structures on the Qinghai-Tibet Railway to_________.
A.let the train run over ice-covered earth during winter
B.stop the railway from moving over the warming earth during summer
C.make things move quickly along the 550 kilometers’ railway road
D.stop the ice-covered earth from getting warm during summer
3. When you drive at a speed of about_________on the musical road in Holland, you can hear a beautiful song.
A.80 km/hB.70 km/hC.50 km/hD.100 km/h
4. All the three kinds of new science and technology introduced here are about _______.

文章大意:这是一篇说明文,简要讲述了计算机的发展史。

【推荐2】What exactly is a computer? That’s not always an easy question to answer. Webster’s Collegiate Dictionary defines a computer as “a programmable usually electronic device that can store, retrieve(检索), and process data”.     1    

For thousands of years, people have tried to improve their lives by inventing machines to make certain tasks easier. Some people believe a simple mechanical device called an “abacus” was one of the earliest forms of a computer.     2     Archaeologists have found evidence that the ancient Greeks used the abacus as early as the 5th century B.C.

Modern computers were developed much more recently. The first modern electronic computer—known as the Electronic Numerical Integrator and Computer or ENIAC—became operational in 1946. Weighing more than 30 tons, ENIAC took up as much space as 1,800 square feet.     3     While ENIAC could perform 5,000 addition problems per second, many of today’s laptop computers weigh just a few pounds and can perform several billion operations per second.

    4     Large desktop computers gave way to laptops. Laptops have developed into a wide variety of even smaller computing devices, such as netbooks and tablet computers. Many people even carry computers with them everywhere they go. Smartphones—cellular telephones with advanced computing capabilities—fit easily into a pocket and allow their users to make telephone calls, surf the Internet, and conduct business on the go.

So what’s the smallest computer available today? As of 2015, the smallest computer is just one cubic millimeter. However, today’s computer manufacturers are constantly producing newer and smaller models at a rate too fast to keep up with.     5    

A.Today, we rely on computers for all sorts of things.
B.Today’s computers keep getting smaller and smaller.
C.Ancient people used the device to perform simple calculations(计算).
D.Since then, computers have become much smaller and much more powerful.
E.Others think a computer is anything that transforms information in a meaningful way.
F.Modern laptops are slow compared to modern supercomputers.
G.Whatever is smallest today will probably be replaced with something even smaller tomorrow!

文章大意:本文是一篇说明文。文章主要介绍了人工智能的相关内容以及其可能带来的风险,并就如何降低风险给出一定建议。

【推荐3】AI is a machine’s ability to perform the cognitive (认知的) functions we associate with human minds, such as reasoning, learning, interacting with an environment, problem solving, and even exercising creativity. You’ve probably interacted with AI even if you didn’t realize it — voice assistants like Siri and Alexa are founded on AI technology, as are some customer service chatbots that pop up to aid you to explore websites.

By using artificial intelligence, companies have the potential to make business more efficient and profitable. But ultimately, the value of artificial intelligence isn’t in the systems themselves but in how companies use those systems to assist humans — and their ability to explain what those systems do — in a way that builds and earns trust.

Since they are so new, we have yet to see the long-tail effect of AI models. This means there are some risks involved in using them — some known and some unknown.

The outputs AI models produce may often sound extremely convincing. This is by design. But sometimes the information they generate is just plain wrong. Worse, sometimes it’s biased, because it’s built on the gender, racial, and various other limitations of the internet and society more generally. And it can even be operated to enable immoral or criminal activity.

These risks can be reduced, however, in a few ways. For one, it’s crucial to carefully select the initial data used to tarin these models to avoid including toxic (中毒的) or incorrect content. Next, rather than operating an off-the-shelf generative-AI model, organizations could consider using smaller, specialized models. Organizations with more resources could also customize a general model based on their own data to fit their needs and minimize shortcoming. Organizations should also keep a human in the process — make sure a real human checks the output of a generative-AI model before it is published or used, and avoid using generative-AI models for critical decisions, such as those involving significant resources or human welfare.

1. What can we learn about AI from the first two paragraphs?
A.Its value lies in its practical application by firms.
B.It performs the same abilities humans own.
C.It’s always being used when we surf the websites.
D.It has been widely used by profitable companies.
2. What does underlined word “biased” in paragraph 4 mean?
A.Unclear.B.Unimportant.C.Unreliable.D.Unusual.
3. Who are mostly responsible for reducing the risks when using AI?
A.Produces and personal users.
B.Developers and operating firms.
C.Personal users and data collectors.
D.Operating companies and personal users.
4. What’s the author’s purpose in writing the text?
A.To analyze the advantages and disadvantages of AI.
B.To lead companies to improve efficiency with AI.
C.To introduce AI and ways to overcome their limitations.
D.To tell customers how to operate AI correctly and precisely.
