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．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．
42．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
43．The third paragraph mainly tells us about the of driverless cars．
A．instructions
B．standards
C．advantages
D．tests
44．The underlined word "potentially" in Paragraph 4 means" "．
A．possibly
B．successfully
C．especially
D．naturally．
45．What's the writer's opinion about future driverless cars？
A．They'll cause more accidents．
B．They'll be less expensive．

It is said that all dreams serve a purpose（目的）. While there is no agreement among scientists about why we dream, there are many ideas about the different kinds of dreams we have.
One common kind of dream is the repeating dream, in which the same story is repeated again and again, often for many months or even years. Some believe these are a sign people have a problem in their life and once that problem is gone then the dream will stop. Others think they are a way to help people remember something very important.
Another well-known kind of dream is the nightmare. The pictures and stories in such dreams make people very afraid and dreamers usually remember them far more clearly than normal dreams. The cause of such dreams may be seeing something terrifying such as a car accident or some deadly snakes. Others think such dreams may be trying to make a person pay attention to something that is dangerous in their life.
Daydreams happen during wake-time when we forget where we are or what we are doing and find ourselves in a made-up story or unreal world. We often daydream when we are doing something that is not interesting or exciting. They help us think about our future.
Lucid dreams are the most fun. These happen when dreamers suddenly understand that they are dreaming. Instead of waking up, they stay in the dream and are able to control what happens in the dream as if they are making a movie.The underlined word “they” (in paragraph 2) refers to “_________”.

When might a person daydream?
| A．During a very interesting movie. |
| B．While playing at a fun park. |
| C．While listening to an uninteresting talk. |
| D．When making a movie. |

| A．We can remember the dream very clearly. |
| B．We can control what happens in the dream. |
| C．We think that the dream is like a movie. |
| D．We feel very nervous after we wake up. |
