今天的句子：
Right now, fully autonomous cars are rolling around Pittsburgh, the San Francisco Bay area, and parts of Michigan, shuttling people from here to there with minimal manual intervention. Instead of fixing the old subway trains, let’s rip out the tracks and fill the tunnels with fleets of autonomous vehicles running on pavement. The result would be radical improvements in throughput while saving money and increasing the ability of the system to survive a fire, flood, or terrorist attack.
词汇突破：
1. fully autonomous cars 完全自动驾驶汽车
2. San Francisco Bay area 旧金山湾区简称(Bay area )
3. rolling around 滚动行驶
4.instead of = not; 这就是一个否定词!记好了!
I will work hard during the vacation, instead of killing time on Douyin.
假期里我会努力而不是在抖音上浪费时间。
Instead= however!
Aman promised the money to JPP. Instead, he gave it to KK，his own true love, finally.
(一男答应把钱给JPP. 但最后还是给了他自己的真爱，KK.)
(注意promise的用法。注意he 和his指代的是 Aman，毕竟有own;his own true love 是KK的同位语。)
这样理解做题才不会出错。你相信我!
5.rip out: 撕毁，拆除，
6.pavement ：路面 (但这里显现不是人行道的意思就是路面)
7. throughput：吞吐量
8.survive sth：渡过，幸免于难
The company survived the crisis.
公司渡过了危机
9. radical improvement: 极大提高，彻底提高
第一句：
Right now, fully autonomous cars are rolling around Pittsburgh, the San Francisco Bay area, and parts of Michigan, shuttling people from here to there with minimal manual intervention.
切分：
1. Right now, fully autonomous cars are rolling around Pittsburgh, the San Francisco Bay area, and parts of Michigan
2. shuttling people from here to there with minimal manual intervention.
参考译文：现在，完全自动驾驶汽车在匹兹堡，旧金山湾区和密歇根州的部分地区滚动行驶，在两个地点之间穿梭运送人们，而且只需很少的手动干预。
思考题一：
Autonomous cars are widely used in many American cities to replace the old trains.
这个说法前面都没有问题包括widely 和many 在考研的选项中加上都可以认为是正确的，这种程度的加减在没有更准确的选项时都是可以接受的。但是最后的to replace the old trains(代替老式的火车)就是不可接受的了。
所以这个思考题是错误的。
第二句:
Instead of fixing the old subway trains, let’s rip out the tracks and fill the tunnels with fleets of autonomous vehicles running on pavement.
切分：
1.Instead of fixing the old subway trains,
2. let’s rip out the tracks
3. and fill the tunnels with fleets of autonomous vehicles running on pavement.
参考译文：不用修理旧的地铁列车，把铁轨拆掉，铺平道路，让自动驾驶汽车组成的车队在隧道里行驶并填满这些隧道。
第三句：
The result would be radical improvements in throughput while saving money and increasing the ability of the system to survive a fire, flood, or terrorist attack.
切分：
1. The result would be radical improvements in throughput
2. while saving money and increasing the ability of the system to survive a fire, flood, or terrorist attack.
参考译文：其结果将是极大提高吞吐量，同时节省资金，以及增强系统在火灾、洪水或恐怖袭击中幸免于难的能力。
思考题二：
The system of subway is vulnerable to fire and flood contrast to the autonomous vehicles.
(和无人驾驶交通工具相比，地铁系统容易受到火灾和洪水的伤害。)
既然文中说了，使用无人驾驶汽车可以提高交通系统的应对火灾和洪水的能力。
所以这个说法是对的。
