Help when parking.
Computers have difficulties making ethical decisions and many people will lose their jobs.
Yes. Because they are convenient. (答案合理即可)
       Smartphones are becoming more and more popular in our daily life. They bring many advantages 
to us. Smartphones greatly enrich our daily life. First, they let us surf the Internet anywhere at any time.
We can get all kinds of information by watching the news about any country in the world. Second, with 
smartphones, we can listen to music, watch films and play games. It is also convenient to do online
shopping. Third, we can keep in touch with each other by chatting on QQ or WeChat. What's more,we can 
learn a lot of knowledge by having online courses.
      However, every coin has two sides. Using smartphones for too long is harmful to health. Some 
teenagers spend too much time on mobile games. As a result, they fail to pass the exams and have poor
eyesight. So using smartphones can affect their study. 
      In my opinion, whether it is good to use the smartphones depends on ourselves. We should use them 
properly to improve ourselves.

題干：計(jì)算機(jī)驅(qū)動(dòng)的無人駕駛汽車如何讀取路標(biāo)?
根據(jù)第二段第3-4行Road signs are read by cameras,道路標(biāo)志由攝像頭讀取，可知，通過攝像頭讀取路標(biāo)。故答案為By cameras.
Help when parking.
題干：車輪上的傳感器能做什么?
根據(jù)第二段第2-3行Sensors on the wheels also help when parking, so the car knows how far it is from the outside of the road or other parked cars. 車輪上的傳感器在停車時(shí)也有幫助，這樣汽車就能知道它距離道路外面或其他停著的汽車有多遠(yuǎn)。可知，車輪上的傳感器在停車時(shí)有幫助。故答案為Help when parking.
Computers have difficulties making ethical decisions and many people will lose their jobs.
題干：無人駕駛汽車的缺點(diǎn)是什么?
第四段第1-2行提到Computers would have difficulties making ethical decisions計(jì)算機(jī)將難以做出道德決策。
以及第五段第2-3行many people would be put out of a job when driverless cars appear.當(dāng)無人駕駛汽車出現(xiàn)時(shí)，許多人將失去工作。
可知，計(jì)算機(jī)難以做出道德決策，并且無人駕駛汽車的出現(xiàn)，會(huì)導(dǎo)致許多人失去工作。
故答案為Computers have difficulties making ethical decisions and many people will lose their jobs.
Yes. Because they are convenient. (答案合理即可)題干：你希望這些由電腦驅(qū)動(dòng)的無人駕駛汽車很快就會(huì)出現(xiàn)在你附近的道路上嗎?為什么?
文章既提到了無人駕駛汽車的優(yōu)點(diǎn)，如：便捷，在遇到危險(xiǎn)情況時(shí)反應(yīng)更快。也提到了其缺點(diǎn)，如：計(jì)算機(jī)很難做出道德決定以及許多人將失去工作。
所以參考答案為：Yes. Because they are convenient. 
       Smartphones are becoming more and more popular (越來越受歡迎) in our daily life. They bring many advantages(有利) 
to us. Smartphones greatly enrich(使豐富) our daily life. First, they let us surf the Internet(上網(wǎng)沖浪) anywhere at any time.
