the difficulty lies _____we have no money.A in that B in the fact that
问题描述：
the difficulty lies _____we have no money.A in that B in the fact that
选A是that 引导的宾语从句做介词in 的宾语,虽然that 一般不引导介词的宾语从句但是in but except 却可以接that 引导的宾语从句,貌似A可以
选B是that 引导的同位语从句,the fact 是先行词,that从句说明fact 的内容
请哪位指教下这个选什么为什么,说明原因
答
答案是in the fact that
that作介词的宾语只用于except that(除了),in that（因为）这两种结构,而本题in是lie in 的搭配,that不能用于lie in 后.
答案B中,the fact 作lie in 的宾语,that 是the fact的同位语.能给举个例子that 从句做in 的宾语吗This book is different from that book in that this one is about chemistry and that one about history. 这本书不同于那本,因为这本是有关化学的,而那本是有关历史的。 （并不是所有的in后都能加that，你可以把in that当固定搭配来记。）
