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. Companies like Google and Tesla have been designing and     1     these cars, and the technology is there.

So how do they work? The cars have sensors (传感器) all around which can find other cars and     2     on the road. Sensors on the wheels also help when     3    , so the car knows how far it is from the stone or other parked cars. Road signs are read by cameras, and GPS is used so the car knows where you want to go. All you have to do is type in the address!     4    , a central computer system takes in all the information it receives from the sensors and cameras and work out when to speed up, turn and stop.

Sound     5     your idea of heaven? Sitting back, looking out of the windows and even watching a film or reading a book while “driving” would be     6     with this new technology. You wouldn’t have to worry about remembering directions where you’re going. In addition, computers are generally better     7     than humans. They would also drive     8     than people — they don’t listen to music or talk with friends, they would follow the speed limit and they have quicker reaction times if something bad happens.

However, there are many downsides of driverless cars. Computers would have difficulty     9     ethical(道德的) decisions; if a child ran into the road, would the computer choose to hit the child or turn suddenly and kill the car’s passengers? There would also be many legal decisions to be made — should children, or drunk people, be allowed in a driverless car by     10    ? Or would there need to be a responsible(有责任的) adult with a driver’s licence in the car at all times?

On Oct. 16, 2016, Chinese astronauts of the Shenzhou-11 mission (任务), Jing Haipeng and Chen Dong, met the press（新闻发布会）Sunday ahead of Monday’s launch.

Sitting under a national flag, the astronauts _______ in good spirits and answered several questions.

“_______ the job is challenging, risky and dangerous, there is nothing more I would rather do,” Jing Haipeng, 50, who is commander of this mission, told reporters. It will be Jing’s _______ spaceflight following his Shenzhou-7 mission in September 2008 and Shenzhou-9 mission in March 2012.

On Monday, China successfully launched   (发射) manned spacecraft Shenzhou-11 carrying the two astronauts who will remain in space for 33 days. The spacecraft was sent up at the Jiuquan Satellite Launch Center in _______ China’s Gobi desert at 7: 30 am. Beijing time Monday with a Long March-2F Y11 carrier rocket. The spacecraft has entered its designated orbit (轨道). The launch _______ a success by Zhang Youxia, about 19 minutes after the blast-off (发射).

Three weeks before the task, the family members of Jing Haipeng and ChenDong still knew nothing. Chen Dong has been a (an) _______ for many years before joining the space team. He and his wife now have a pair of five-year-old twin sons. One-month mission is not the longest time that Chen _______ away from home. When he was a pilot , he once did not come back home for half a year during a mission.

Chen Dong described the experience as “no seeing, no _______.” But with the help of Virtual Reality (虚拟现实) (VR) technology, astronauts will meet their family during free time. “If I see them (family members) , it will be different somehow,” Chen said.

3 . Artificial intelligence(人工智能), or AI in short, is the science of giving computers and machines ability to think and work like humans. AI scientists and engineers have made a lot of cool technologies.

AI is rapidly catching up with the human ability to read faces. As a result, facial recognition(识别) is used a lot in the world. Chinese police use this technology to identify criminals(罪犯). Once they caught a criminal when he attended a concert. It also checks the ID of ride-hailing(网约车) drivers and lets people pay for things with a smile.

AI is also used in self-driving cars, which are believed to be the future of driving. Most drivers may wave or nod at passers-by to let them cross the street, but self-driving cars don't have this ability. Carmakers are testing a light signal system to help them "speak" to humans. The system can show what self-driving cars will do. For example, if a driverless car is yielding(让路), it will flash two white lights side to side. A rapidly flashing light tells passers-by that the car is about to speed up.

Service Robots also show you how powerful AI is. Imagine this—you come back home from school and your robot housekeeper is waiting for you at the door. After dinner, he teaches you to play the piano, just like a real music teacher. Such thoughts will soon happen in the real world. In the future, more and more service robots will become good home helpers.

AI is so powerful that it can help human beings and even replace us in many jobs.

3. Which technology has been used in real life according to the passage?

A．Service Robots at school.	B．Robots as ride-hailing drivers.
C．Facial recognition for payment.	D．Light signals for self-driving cars.

4. What can we learn from the passage?

A．People use AI in many different ways.	B．AI will take the place of human beings in all jobs.
C．Self-driving cars will be able to talk like humans.	D．A criminal was caught for inventing facial recognition.

4 . Take a piece of hair from your head. Ouch! It may be long, but it’s not wide. Three scientists spent over 30 years _______ a kind of machine. This kind of machine is about a thousand times _______ than the width of one piece of your hair. These machines are _______ small that they can only be seen under a microscope(显微镜)! They _______ nanomachines(纳米机器).

Because of their hard work, the three scientists _______ the 2016 Nobel Prize in Chemistry. They are all Europeans. Sir J. Fraser Stoddart, one of the scientists, told reporters that he thanked hundreds of other scientists from 24 different countries for helping make this prize _______. He said he once brought a chocolate Nobel Prize to his daughter from a trip to Stockholm. He expected _______ a real one someday.

What are nanomachines good for? Scientists believe that _______ the future, nanomachines can help deliver(传送) medicines inside a person’s body, or take away things that are making us sick. Mr. Feringa compared _______ work to that of the Wright Brothers. When the Wright Brothers flew their airplane for the first time, some people questioned what airplanes _ good for.

5 . A British supermarket became the first in the world to let customers pay by using just the veins(静脉) in their fingers in September, 2017.

Customers at the Costcutter store, at Brunel University in London, can now pay by using their vein map.

The company behind the technology, Sthaler, said it was in “serious talks” with other big British supermarkets to use high－technology finger vein scanners(扫描器)．

It works by using infrared(红外线) to scan people's finger veins and then connects this map with their bank cards.Customers' bank details are then stored with payment provider Worldpay, in the same way you can store your card details when shopping online.Shoppers can then go to the supermarket with nothing on them but their own hands and use it to make payments in just three seconds.It requires the person to be alive.It means that if a criminal cuts off someone's finger, it would not work.

It's reported that fingerprint recognition(指纹识别)，used widely on mobile phones now，is unsafe and can be copied even from finger smears(指纹残留) left on phone screens.But vein technology is safer as it cannot be copied or stolen.

Sthaler said nearly fifty students were already using the system and it expected 3,000 students out of 13, 000 to have signed up by November.

Simon Binns, commercial director of Sthaler, told The Daily Telegraph, “This makes payments so much easier for customers.This is the safest form.”

6 . When we discuss inventions, many of us think of some important things such as planes, trains and computers. In fact, many inventions are c    1     and they are often used in our daily life. However, we even don't know w    2     invented them.

There are a lot of things in our schoolbags, i    3     pencils, rulers, books and so on. None of them grow in the field. People make them in factories. They look common today, but hundreds of years ago no one knew about them. Who invented them? Where were they invented? We aren't sure. However, we should thank the inventors. Their inventions are so important to us. We couldn't e    4    such a wonderful life without their inventions.

Some of the inventions have changed not only our life but also the w    5    world, such as the telephone, the TV and the computer. We use them every day, but most of us don't know the names of the inventors. Should we remember the inventors? We can remember so many movie stars and pop stars. Why don't we pay more attention to the scientists and inventors? We should look on them as stars in our eyes!

7 . The Chang’e-3, named after a Chinese goddess, is China’s first spacecraft(航天器) to make a soft landing on the moon. It includes a lander and a moon rover(月球车) called Yutu. The Chang’e-3 spacecraft is the second phase(阶段) China’s lunar programme, which includes orbiting, landing and returning to Earth. It follows the success of the Chang’e-1 and Chang’e-2 spacecraft in 2007 and 2010. The launch of Chang’e-3 was successful.

The Chang’e-3 is one of the most difficult tasks in China’s space programme, the news says. The news adds that exploring the universe(宇宙) and seeking peaceful use of space are dreams of Chinese for thousands of years.

With a lander and the moon rover Yutu, Chang’e-3 soft-landed(软着陆) on the moon at 9:11 p.m. Saturday. Yutu later separated(分离) from the lander and ran to the moon surface earlier Sunday.

China has chosen the name Yutu for its first moon rover, after a worldwide online vote(投票) attracted people to come up with names.

In Chinese folk tale, Yutu is the white pet rabbit of Chang’e, the moon goddess. Chang’e took her pet and flew towards the moon. She became a goddess and has lived there with the white animal ever since.
