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 testing these cars, and the technology is there.
So how? The cars have sensors(感應(yīng)器)all around which can find other cars and objects in the road. Road signs are read by cameras, and satellite navigation systems(衛(wèi)星導(dǎo)航系統(tǒng))are used so the car knows how to get where you want to go. All you have to do is type in the address! 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. In addition, computers would also drive more safely than people — they would obey the rules and have quicker action times when in dangerous situations.
However, there are many drawbacks of driverless cars. 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 and potentially kill the car’s passengers? Moreover, I personally find driving fun –I’d miss never driving a car myself. There would also be many other decisions to be made –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 – but it’s only a matter of time before they’ll become more affordable and popular on our roads.
1.When using a driverless car, you need only .
A. read the road signs carefully B. check the cameras
C. put the address into the computer D. remember the directions
2.The third paragraph mainly tells us about the of driverless cars.
A. instructions B. standards C. advantages D. tests

Many kids do housework such as doing the dishes, making the bed, and folding the clothes. In exchange, they get some money or other computer time.
Paying kids for housework is one of the most popular topics, especially at a time when everyone is more careful about money. Some parents think since adults are paid to do their jobs, we should pay kids for everyday housework.
But some people don't think kids should get rewards(報(bào)酬) for doing housework. Susie Walton, an expert, believe that by rewarding kids, parents are sending a message that work isn't worth doing unless you get something in return. “Running any kind of housework is a team effort,” Walton said. “A home is a living space for everyone in the family. It's important for kids to see that we all have responsibilities in the house, and families decide how they want their home to look, and how they are going to keep it looking like what they want.”
Other people believe that getting a reward encourages kids to do housework, and it also teaches them real world lessons about how we need to work to get money. There are also apps(程序) that gives kids points and digital gifts that can be redeemed(兌現(xiàn)) either online or in the real world. “Our goal is to give kids lawful power so they can get rewards,” says Chris Bergman. “And kids need rewards to help encourage them. ”
1.Which of the following housework is NOT mentioned in Paragraph 1?
A. Washing the dishes. B. Cooking meals.
C. Folding the clothes. D. Making the bed.
2.The underlined phrase “in return” in Paragraph 3 has the same meaning as “_____”.
A. as a reward B. for punishment C. on sale D. under control
3.What's Walton's idea in the passage?
A. Running exercise is a kind of team work.
B. People work to get some rewards.
C. Kids have responsibilities in the house.
D. Doing the housework in only the parents' job.
4.According to Chris Bergman, kids should be encouraged to ______.
A. do housework without rewards B. do more housework
C. stay away from housework D. do housework by getting rewards
5.Which is the best title for the passage?
A. Kids Should Study as Well as Doing Housework
B. Let Children Do Some Housework
C. Should Kids Be Rewarded for Doing Housework
D. Doing Housework Is Good for Children's Study
