Question

But the latest research further confirms that the danger lies less in what a motorist's hands do when he takes a call than in what the conversation does to his brain.
谁能帮我分析分析这句话
主要是the danger 后面的
in what
这些事句子什么成分
怎么理解

Answer 1

最近的研究表明,开车时讲电话的危险,在电话里对话对大脑的影响要大于驾驶者手部在做什么（即讲电话本身).
你要把danger lies in倒过来理解,a motorist's hands do is less than the conversation does to his brain.你说的in（what XXXXX）,是动词lies in what从句.
搞忘了术语对不对,反正这么理解就对了.语法搞忘很多年了.
