选择题
-- Are you sure that he will come here in time?
--- You may ______ he will come to help us though he is very busy.
A．rely upon that
B．rely upon it that
C．rely upon what
D．rely upon it what
答案
答案：B
题目分析：考查it做形式主语，词组rely on后面不能直接接从句，要先接it做形式宾语，再接that从句，句意：--你确信他会准时到这儿吗？--你可以相信虽然他很忙他肯定会来帮我们的。选B。
点评：英语中有的词组是不能直接加从句的，要先接it再接从句，这样的词组有see to，depend on，relyon等后面都是先接it再接从句。
