5、品质的词时，常用“It + be +形容词+ of sb. + to do”，相当于“Sb. is +形容词+ to do”；部分形容词后接不定式，用主动形式表示被动意义，该句型的主语是不定式的逻辑宾语，常见的此类形容词有：comfortable, easy, dangerous, difficult, expensive, fit, impossible 等。2. 当动词不定式充当宾语且其后有宾语补足语时，常用形式宾语 it 代替不定式，即“主语+谓语动词+ it +宾语补足语+ to do” 。3. 介词 but, except, besides 等前如有动词 do 时，其后一般用不带 t
6、o 的不定式；如其前没有 do，则一般接带 to 的不定式。4. 部分动词（如 believe, consider 等）后常接“to be +形容词、名词短语等”，有时 to be 可省略，但当不定式是完成式时，to 不能省略。5. 感官动词和使役动词后用作宾语补足语的不定式须省略 to，但此类句式变为被动语态时，to 不能省略。6. 一些动词如 like, hate, love, prefer 等前面加上情态动词 would 时，其后要用不定式。7. 动词不定式与被修饰词之间是动宾关系时，如果不定式是不及物动词，动词后需跟与其相搭配的介词。8. 由序数词，last，plenty of 等修饰
7、的名词常用不定式作定语，另外，next，only 或形容词最高级修饰的名词后也常用不定式作定语。9. 不定式作状语表示目的，或用于 so as 或 in order 之后来强调目的，so as to 一般不用于句首；不定式可以表示结果，特别是 so . as to, such . as to, only to . 以及 too . to 等结构中。10. “wh- 疑问词+ 不定式 ”或“whether +不定式”构成的不定式短语，其作用相当于一个从句，常作某些动词的宾语，此类动词有 know, see, decide, tell, ask, consider, discover, expla
