____doesn't seem to have been any trouble in solving this problem
A It
B there
C that
D he
答案是b,我想问怎么解释这个选项.并请分析下为什么不选a
为什么是there be的句型呢?怎么看出来的呢?

这就是一个there be in sth的句型的变型
如果用it的话
后面必须有形式主语
改成it doesn't seem to have been anytrouble to solve this problem

记住吧,这是there be 的一种用法,be 可以用一些词组代替.再给你点素材吧
there happen to be ,,remain,,enter,live, stand,lie.etc
