Imagine having a simple app (应用程序) that works like: When you need help, just open the app, touch the “notOK” button and a message will be sent to five pre-selected (预先设定的) people, along with a location to show where you are.

文章大意:本文主要讲述了最有可能在10到30年后发生的一些事——数字货币、仿生眼及自动驾驶汽车。

【推荐1】What’s going to happen in the future? Will robots control our planet?     1     Not likely. But here are some things that scientists say are most likely to happen in 10 to 30 years from now, according to the BBC.

Digital money

We need to pay with cash for everything we bought. Now when we use a credit card to shop online, money is spent without us seeing it.    2     Using a card is much easier than searching our pockets for change. It is also safer than carrying a lot of cash.

Bionic (仿生的) eye

    3     People who are blind may have a chance to get their sight back — by wearing bionic eyes.

A blind eye can no longer sense light, but a bionic eye can use a camera to “see” the environment and send data to the mind.     4     A high resolution (高清的) image could be just a few years away.

    5    

Unlike a human driver, a self-driving car won’t get distracted (分神) by a phone call, the radio or something outside the window. Sensors (探测器) and cameras on the car would allow it to stick strictly to the rules of the road and keep a safe distance from other cars. This would greatly reduce the number of road accidents. You could even take a nap while the car drives itself. In the future, driverless cars would be widely accepted.

A.That means we are already using digital money.
B.Will computers become smarter than us?
C.Self-driving cars
D.Now the bionic eye only allows patients to see lights and unclear shapes.
E.It’s no longer something only in a science fiction movie.

【推荐2】Artificial intelligence or AI, is defined as “the capability of a machine to imitate intelligent human behavior”. It is around us every day. AI is set to benefit mankind in many ways. Imagine being able to hop in a car, tell it your destination, and sit back in comfort as the AI-guided self-driving car takes you there. Imagine having an AI tutor that could help you with your schoolwork. It will make everyday tasks easier and bring efficiently to various industries. AI might just prove to be one of man’s greatest inventions.

______________________ In February 2018, a group of AI experts got together to discuss the possible misuse of AI. What they found was that “Every AI advance by the good guys is an advance for the bad guys, too,” according to Quartz.

Their biggest concern was that criminals could use AI for wrong purposes. One of the areas they looked at was the use of AI to create websites that could be used to steal people’s personal information. Another possibility is that AI programs could be taught to hack software and break into computer secure systems.

There are some other concerns as well. It is possible that AI could be used to create fake imagines and videos. Chinese tech giant Baidu, in fact, has developed a program called Deep Voice that can “clone” anyone’s voice by studying a 3.7-second audio sample.

Many leading figures in the tech world have expressed concern about AI. People like Bill Gates and Elon Musk have called for the industry to be more strictly regulated, as there are few laws right now on the use of AI.

However, this is set to change. In March 2018, the European Union plans to set up a group that will discuss the moral and ethical dangers of advanced AI—and hopefully, suggest some regulations that will help us keep it safe for mankind.

1. Why do some experts have concerns about AI?
A.Because it makes people lazier.
B.Because some people may use it to do wrong things.
C.Because it will replace workers in many industries.
D.Because it is developing too fast.
2. Which of the following is the best to fill in the “_________” in Paragraph 2?
A.Convenience is the main advantage of AI.
B.The technology of AI is increasing.
C.However, AI will replace humans one day.
D.And yet, like any other technology, AI will also bring risks.
3. Deep Voice is mentioned to show _________.
A.How AI is developedB.What AI can do in the future
C.Why Baidu is a tech giantD.How AI can copy voices
4. What can we infer from the story?
A.There may be new laws to regulate the use of AI.
B.AI will bring more harm than benefit to mankind.
C.Many AI programmers will become criminals.
D.There will only be fake news and video online.

【推荐3】There is much heated discussion today about 5G. Your Internet experience is not pleasant when the net speed is too slow — it takes so long to open a web page and the talk show you’re watching stops every few minutes. But soon it could be a thing of the past. On June 3, 2020, the Chinese government announced (宣布) that 5G services would be provided around the country.

5G is the 5th generation network. It is a new network after 1G, 2G, 3G and 4G and it can connect everyone and everything together. 5G speed can be very fast. In the near future, 5G network will cover many cities in China.

5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission (传输) to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Even airplanes will become “smart” in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet or order food and drinks.

5G will be a big help for students who take online classes. In the world, many people live in poor areas where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.

In addition, 5G will be used in hospitals. It will be easier for doctors to care for patients who live far away by 5G.

However, 5G has its own weaknesses. According to China National Radio, though 5G will make our lives easier, it will not be perfect. For one thing, 5G will not “travel” far. On 4G networks, you can be 10 kilometers away from the nearest transmission centre and connect the Internet easily. But 5G will only cover about 300 meters. And in order to use 5G, we will have to buy new products specifically designed for 5G that are expensive at present.

1. The underlined word “it” in Paragraph 1 refers to ______.
A.the talk showB.the slow net speedC.the web pageD.the heated discussion
2. According to the passage, 5G will make ______ possible in people’s life.
①online classes        ②self-driving cars             ③“smart” airplanes             ④hospitals without doctors
A.①②③B.①②④C.①③④D.②③④
3. Paragraph 6 is mainly about the ______ of 5G.
A.productsB.networksC.centersD.disadvantages
4. What’s the purpose of the passage?
A.To show 5G is perfect.B.To give an introduction of 5G.
C.To call on people to use 5G.D.To explain how 5G becomes popular.
