句子主語(yǔ)與不定式動(dòng)詞為動(dòng)賓關(guān)系時(shí)，我們要注意以下三點(diǎn)：
1）不定式一般不用被動(dòng)式（最容易出錯(cuò)），而多用主動(dòng)形式表示被動(dòng)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(yǔ)：
a. Football is very interesting to watch it.*
b. She is very nice to talk to her.*
3）不定式動(dòng)詞所帶的介詞不能省略：
a. She is interesting to listen.*
b. She is easy to get on.*
