Question 2 is based on the news report you have just heard.

听力原文：

    One of Google’s self-driving cars crashed into a bus in California last month. There were no injuries.It is not the first time one of Google’s famed self-driving cars has been involved in a crash, but it may be the first time it has caused one.

    On February 14th the self-driving car, travelling at 2mph (3km/h), pulled out in front of a public bus going 15mph (24km/h).

    The man in the Google vehicle reported that he assumed the bus would slow down to let the car out, and so he did not switch to the manual mode.

    In a statement, Google said: “We clearly bear some responsibility, because if our car hadn’t moved, there wouldn’t have been a crash.”

    （1）That said, “our test driver believed the bus was going to slow or stop to allow us to merge into the traffic, and that there would be sufficient space to do that.”

    （2）The company’s self-driving cars have done well over a million miles across various states in the US, and until now have only reported minor accidents.

2. How have Google’s self-driving cars performed so far?

解析：D。本题目为细节题。问题为：目前，谷歌公司自动驾驶汽车的表现如何？出题点位置在文章尾段尾句。根据原文“The company’s self-driving cars have done well over a million miles across various states in the US, and until now have only reported minor accidents”，可见谷歌的自动驾驶员在美国各州的测试公里数已经超过了一百万英里，并且至今仅发生过一些小的故障。本题目较简单，关键词为done well，并且only report minor accidents含义与general 大致上所表达的引申义相同，视听一致即可选出正确选项D）They have generally done quite well.
