【问】
Since you have repaired my TV set, ____ is no need for me to buy a new one.
A. there B. it
答案：A
问题：there is和it is句型难以区分，通否总结一下这两个句型？
【答】
There is句型除了上面的there is no need，还有：
- There is no possibility that Bob can win the first prize in the match.
- There is no point saying that again.
常用的it’s句型有：
- It is no use crying over spilt milk.
- It is no wonder that he is so excited.
- It is no surprise that he is a thief.
- It is no good doing it now.
注：There is no use doing sth和It is no use doing sth都是正确的，后者更常用些，但是前者以出现在人教社高中英语教材必修一第三单元课文中。
