【解析】【聽(tīng)力原文】 Of two eggs, can you find out which is the boiled egg and which is the uncooked one? Maybe you think it's difficult because they both look the same. But there's an interesting and easy experiment for us to find it out. Before the experiment, make sure you have the following things: two plates, one boiled egg and one uncooked egg.

Put the two eggs on the two plates and start spinning them at the same time. The egg that can spin for a longer time is the uncooked egg.

Why can the uncooked egg spin longer? Now we can do the second experiment. Put the uncooked egg on a plate, and make it spin. Then touch it with your finger to stop the spinning. Once the egg stops spinning, take your finger away at once.

What happened to the egg? The shell of the egg actually stops spinning, but its inside is still spinning because it's liquid. On the other hand, the boiled egg can stop quickly because it's solid inside.


（1）根據(jù)這句Before the experiment, make sure you have the following things: two plates, one boiled egg and one uncooked egg. 故選A。
（2）根據(jù)這句The egg that can spin for a longer time is the uncooked egg.Why can the uncooked egg spin longer? Now we can do the second experiment. 可知在第一個(gè)實(shí)驗(yàn)中得知未煮的蛋停的晚了些。故選B。
（3）根據(jù)這句Why can the uncooked egg spin longer? Now we can do the second experiment. 故選C。
（4）根據(jù)這句The shell of the egg actually stops spinning, but its inside is still spinning because it's liquid. 故選B。

【題目】閱讀下面材料, 從每題所給的A, B, C, D四個(gè)選項(xiàng)中選出最佳選項(xiàng)。(C )
A major development to self-driving cars may change the way we will drive in the future. Google, the leading company in self-driving technology, has changed its develop plan. It had driverless cars built by car factories, but now it will start building its own cars.
Google has started to build some kinds of experimental electric self- driving cars that look like a Smart car or Fiat 500. There is no steering wheel(方向盤(pán)), gas pedal or brake. The only things a human passenger controls are a red "e-stop" button (按鈕) for fear stops and a start button. The car's only "friendly" face is designed to make it help people accept self-driving technology.
Google workers took part in a long experiment, in which they used self-driving cars for their usual travel to work. No accident happened, but Google's heads realized that depending on a human passenger to drive in an emergency(緊急情況) wouldn't work because they may be reading, working , or sleeping. Now the self-driving car drives by itself if the driver takes his hands off the wheel for over ten seconds.
Google recently announced that its cars had covered 700,000 miles of public roads, and they were now running in busy city streets. People who love self-driving cars say this will improve transport by making roads safer, cutting down accident, and making less pollution.
Of course, there's no need to look for parking at a crowded shopping mall. Instead, users could let their self-driving cars drop them off to park itself. A mother who took a test ride said that having the car would allow her more time to catch up with her son. The cars could also allow people who might not be able to drive to enjoy the hand-free driving. And drunk driving? Not a problem. It is very likely that by 2020, driverless cars will be common. Do you believe so?

（1）What is Google's plan about driverless cars?
A.It will have driverless cars built by car factories.
B.It will give up its plan to make driverless cars.
C.It will start building its own driverless cars.
D.It will help other companies to make cars.
（2）The second paragraph mainly describes about ____________.
A.Google self-driving cars
B.Smart car or Fiat 500
C.a red "e-stop" button
D.gas pedal or brake
（3）What advantage of self-driving cars is not mentioned?
A.They can start the engine by itself and make people's hands completely free.
B.They can help to solve air pollution and reduce car accident.
C.They can park by themselves and make mothers look after young kids easily.
D.They can help those disabled people to enjoy the driving.
（4）We can guess from the last paragraph that ______________.
A.self-driving cars are too expensive
B.there will be fewer self-driving cars
C.there will be more self-driving cars
D.the government will stop Google's plan
