句子主語與不定式動詞為動賓關系時，我們要注意以下三點：
1）不定式一般不用被動式（最容易出錯），而多用主動形式表示被動含義：
a. English is difficult to be spoken.*
b. Football is interesting to be watched.*
2）不定式后不能再加賓語：
a. Football is very interesting to watch it.*
b. She is very nice to talk to her.*
3）不定式動詞所帶的介詞不能省略：
a. She is interesting to listen.*
b. She is easy to get on.*
