Question

Flank's dream was to have his own shop__to produce the workings of his own hands.
A.that B.in which C. by which D.how
答案是B 能理解,但是从句得主语是什么呢?
类似的,what to do? where to go? 是什么结构呢?

Answer 1

从句主语是to produce the workings of his own hands.还原回去是to produce the workings of his own hands in his own shop.which指代的his own shop.what to do?where to go?是一个宾语性质的短语.
