Ⅱ. Fill in the blanks according to the text.
How do selfdriving cars work? 1.___________(put) simply, selfdriving cars must “see” and “behave” 2.___________(appropriate) to be safe on the road. First, cameras as well as sensors capture a 3.___________(vary) of data from the external environment. Then the data is sent to the AI system so that it 4. (analyse) and the car can “see” its surroundings 5.___________ determine its position. Meanwhile, the AI system identifies patterns from the data and learns from them to instruct the car how to “behave” in real time.
However, in reality 6.___________(technology) barriers exist in the development of selfdriving cars. Road traffic in the real world is so 7.___________(complicate) that unfamiliar or unexpected conditions may occur at any time. Selfdriving cars would have to make ethical responses in specific circumstances. Besides, in this 8.___________(emerge)industry, manufacturing and programming standards are not yet uniform. Moreover, the quality and safety of the technology used in selfdriving cars is still being challenged.
There are many challenges, but selfdriving cars will form 9.___________ big part of our future. While there are obstacles ahead, the eventual destination is bound to be another milestone for humankind's 10.___________(amaze) vision and inventiveness.
Activity 5: Warmup for the next period.
Preview the new words and find the English expressions of the following Chinese in the text.
1. 扫视;浏览;匆匆一瞥 2. 提前
3. 面对(某事物) 4. 有过错,有责任
5. 简而言之 6. 像拼图一样进行组合
7. 确定其位置 8. 减速
9. 按照行动计划行驶 10. 在特定的情况下
11. 在理论上 12. 意想不到的情况
13. 在阳光明媚的天空下 14. 提出……的问题
Activity 1:
Ⅰ. 1—5 BCDBA
Ⅱ. 1. To take an example to show a scene that one day selfdriving cars will be applied to people's daily life.
2. The AI system, the “brain” of the selfdriving car, analyses the data and puts it together like a puzzle so that the car can “see” its surroundings and determine its position.
3. Selfdriving cars stay in the lane, move into another one, speed up or slow down according to the action plan created by the AI system.
Activity 2:
1. It all depends. If the programme goes wrong, the driver shouldn't be responsible for the accident. But the final agreement on laws and regulations should make it clear how the insurance company should compensate for the loss. So the relevant laws and regulations should be more explicit at the same time.
2. Selfdriving cars are facing many challenges such as technological barriers, ethical choices and the legal situations.
3. It means that in the future the scientists will find the solutions to the problems and challenges that selfdriving cars are facing now. So we need enough time to improve selfdriving cars and make them better.
Activity 3:
1. I think the people in selfdriving cars are as important as pedestrians but those who are in selfdriving cars should make greatest efforts to avoid hurting pedestrians at first at any time.
2. In my opinion, whether technological barriers are overcome or not, human control is always vital in case any unexpected problem happens. For example, if there is something wrong with the programme, people can repair and correct it in time to prevent major accidents.
Activity 4:
Ⅰ. 1. casually 2. glanced 3. readily 4. What 5. confronted 6. perception 7. safety
8. service 9. ageing 10. is taking
Ⅱ. 1. Put 2. appropriately 3. variety 4. is analysed 5. and 6. technological
7. complicated 8. emerging 9. a 10. amazing
Activity 5:
1. glance at 2. ahead of time 3. be confronted with 4. at fault 5. put simply 6. put together like a puzzle 7. determine its position 8. slow down 9. move in line with the action plan 10. in specific circumstances 11. in theory 12. unexpected conditions 13. against the bright, sunlit sky 14. pose the question of…
