有关语法的
23.He was sitting there,______ in deep thought.
A.lose B.lost C.being lost D.losing
为什么是选B而不是选D呢?不是说伴随动作要用ING的吗?
答
其实这里是伴随状语.一般伴随状语有两种情况：一种是ing形式,一种就是表语或被动语态.被动语态和表语也是可以做伴随状语的.其实该句子是两个合并的 He was sitting there ,and was lost in deep thought.短语be lost in 是陶醉于.的意思,是一个被动语态,也可以看成是表语.上面两句合并后,就变成了He was sitting there,lost in deep thought.
