【推荐2】①AI (artificial intelligence 人工智能) and machine learning refer to the ability of machines to learn and act intelligently. It means they can make decisions, finish tasks, and even tell the possible future results based on what they learn from data (数据).

②AI and machine learning already play a bigger role in everyday life than you might imagine. Health care, banking, video games, every search on the Internet you make..., all are driven by AI.

③AI is going to change almost every field of modern life. Stephen Hawking said, “Success in creating AI would be the biggest event in human history.” And Hawking added at once, “Unluckily, it might also be the last, unless we learn how to avoid the risks.”

④ ▲     especially when you consider some countries are racing to develop AI-enabled autonomous weapons (人工智能自主武器). It is also going to change and take the place of many human jobs. The same worries also come from the public. According to the survey result from Centre for the Governance of AI, 91% of the people (tend to and totally) agree that “AI is a technology that requires careful management” in Europe.

⑤But rather than agreeing with an idea of a helpless future where all human jobs are given over to robots, some people believe AI will make on working lives better. It will improve the work of humans, and new jobs will appear to take the place of the old ones.

⑥What’s more, machines become more intelligent and they are able to finish more human tasks. Things which only belong to humans lie creativity and critical (批判性的) thinking, will become even more valuable in the future.

⑦Like it or not, AI is here. Maybe changing ourselves and managing it well are the best way out. Just as Benjamin Franklin once said, “When you’re finished changing, you’re finished.”

【推荐3】Have you ever seen a car without a driver? It sounds crazy, but these computer-driven driverless cars will soon be filling roads near you.    1    

So how? The cars have sensors（感应器）all around which can find other cars and objects in the road. Road signs are read by cameras, and satellite navigation systems（卫星导航系统）are used so the car knows how to get where you want to go.     2    .Finally, a central computer system takes in all the information that it receives from the sensors and cameras and works out when to speed up, stop and turn.

Sound like your idea of heaven（天堂）? Sitting back, looking out of the windows and even watching a film or reading a book while ‘driving’ would be possible with this new technology. You wouldn’t have to worry about remembering directions to where you’re going.    3     they would obey the rules and have quicker action times when in dangerous situations.

    4    .Computers would have difficulties making ethical（道德的）decisions: if a child ran into the road, would the computer choose to hit the child or turn suddenly in the risk of   killing   car’s passengers? Moreover, I personally find driving fun 一I’d miss   driving a car myself.     5    . Should children, or drunk people, be allowed in a driverless car by themselves? Or would there need to be a person with a driving license in the car at all times?

I’m not certain I’d want a driverless car 一 but it’s only a matter of time before they’ll become more affordable and popular on our roads.

A．However, there are many drawbacks of driverless cars.

B．Companies like Google and Tesla have been designing and testing these cars, and the technology is there.

C．What’s more, computers would also drive more safely than people .

D．All you have to do is type in the address!

E．The driverless car knows all the directions well.

F．There would also be many other decisions to be made .

【推荐1】More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment. Maybe that's why there are 1.4 billion bicycles and only 100 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

【推荐3】Do you have a pet? Many children like pets and even treat (对待) them like humans sometimes. They like to kiss or hug (拥抱) their pets. But this can make them ill (生病的), according to Daily Mail.

Kissing or hugging pets such as dogs and cats can expose (使接触) people to drug-resistant bacteria (耐药细菌), British scientists said.

Many pet owners (主人) give their pets antibiotics (抗生素) when they get ill. But taking antibiotics too often can affect the bacteria inside your pet. The bacteria can become drug-resistant. When people kiss or hug their pets, this kind of bacteria can move to them and make them ill.

Close relationships between pet owners and their pets are important. But if pet owners follow the rules below, they will not get ill.

Rules for playing
● Do not kiss your pets on the mouth.
● Do not let your pets touch your mouth or nose.
● Wash your hands after touching or playing with your pets.
● If you have a wound (伤口), cover it. This way, bacteria cannot pass on to you from your pet.

【推荐1】If you look at the top of your phone, you’ll usually see a little symbol that says 3G or 4G. The “G” stands for the “generation（代）” of your mobile network. But these symbols will become things of the past after 5G networks fully arrive.

On March 30, Shanghai vice-mayor（副市长）Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported. Shanghai has also become the first city in China to start testing 5G networks.

About 100 times faster than 4G networks, 5G will let people download and upload data faster than ever before. But 5G won’t just bring faster mobile internet. People can use it for many other things as well.

For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem-lag（延迟）. When the car “sees” an obstacle（障碍物）, it sends this information to a data center and receives instructions.

However, it takes time to send and receive this information. With this kind of lag, the cars might crash because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer, according to CNNU.

5G could also be used to power the internet of things（IoT, 物联网）. This refers to a large online network that connects all things and people. Fast internet speeds will be the key to developing this technology.

The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically（自动地）place an order online for eggs when it finds that there are no eggs left inside.

1. In which city was 5G tested for the first time?

A．Beijing.

B．Shanghai.

C．Shenzhen.

D．Guangdong.

2. We can infer from the story that ________.

A．5G is all over China	B．there are no symbols at the top of our phones
C．we can now buy self-driving cars	D．5G networks are much faster than 4G or 3G

3. The writer uses self-driving cars as an example to ________.

A．explain how 5G’s fast speed can be helpful

B．show us how advanced self-driving cars are

C．warn about the possible dangers of self-driving cars

D．explain how self-driving cars work

4. According to the story, the IoT is ________.

A．a robot that can do housework

B．an online store where you can buy anything

C．a large online network that connects things and people

D．a type of high-tech refrigerator

【推荐2】China is running ahead in 5G. In March, 2019, the Shanghai Hongqiao Railway Station became the world's first 5G railway station. Now, it takes only 20 seconds to download a long movie there.

We are moving closer and closer to the 5G world. However, the new technology is still strange to most of us. What is 5G. after all? At first, 5G is fast. 5G will be much faster than today's 5G networks.

The first 5G modem of the IT Company Qualcomm supports speeds of up to 5 gigabytes per second. Most of us have never experienced anything close to that speed. And we are only talking about the first generation of modems. Future models are likely to be even faster.

But 5G is not all about speed. Have you ever been to a large event where your data connection slowed down? That is because 4G networks can only support a certain number of devices per square kilometer. 5G network will be able to do much better. They can support up to a million devices per square kilometer.

Now, you begin to understand why 5G is a huge change over 4G. The technology is not just for the smart-phones. It has a strong influence on every connected device. With 5G, self-driving cars will be able to communicate with the world around them as quickly as possible, Wearables, PCs and smart home devices will be able to improve as well.

Are you looking forward to that 5G world now?

1. Each of the following is mentioned about 5G EXCEPT ________.

A．the first "5G railway station" in the world

C．Five

D．Six

4. What's the best title for the passage?

A．What's 5G?	B．How is 5G used?
C．Is 5G good or bad?	D．How's the future life?
