首先，你要明白：doing 是一种省略出来的形式，如metal ,giving way to stone, becomes a material in modern time.----这句话就是metal gives way to stone, and (metal) becomes~~.也就是说，如果你要用doing ,那么一定要注意能否找到其‘发出者’，或者说二者是否一致；
其次，疑问词（这里用which说明）+to do ，其一是惯用语，其二就是为了避免上述情况。新概念里有这样一句话：they hardly know which facts to select from evidence. 如果要把to select from 变成doing 的形式，这就要找到doing的发出者---which facts, 而句型 select sth from sth，即为select (which facts) from sth，也就是说要用被动done 而不是doing。于是整句话为they hardly know which facts selected from~~. 可见，这样的被动形式，看上去就不如to do那样整洁，而且找到select 的先行词也是很麻烦的事情---因为前面已经有which（facets）。
