Id like to be informed of the process of your dealing with my complaint. (3)构成宾语补足语或主语补足语：By that time, Tony expected the house to be completely transformed.（宾语补足语） She didnt like herself to be praised like that. （宾语补足语）As Tony was not allowed to accompany her to the shops, he wrote out a list of items for her.（主语补足语） (4) 作定语：Are you going to the meeting to be held in the teachers office?(5) 作状语：She was too young to be assigned such work.2.不定式有时还可以有完成式的被动式，在句中作主语、宾语、定语，或真正的宾语、复合谓语等，如：He thought it an honor to have been invited to the party. （真正的宾语）The book is said to have been translated into many languages. （复合谓语）She was the first woman to have been elected to such a post. （定语） 三、不定式的主动形式表示被动1. 在there be结构中。例如：There is a lot of homework to do There is no time to lose (to be lost). 2. 在“npron + be + adj + to do”结构中。常用的形容词有easy，difficult，hard，impossible，nice，pleasant，interesting，important，dangerous等。例如：He is hard to convince. He is an impossible person to work with3. 在“tooto do; enoughto”结构中。例如：The problem is too difficult to work out The house is big enough to live in.4. 在“with+宾语+to do”结构中。例如：With nothing to do, he lay in bedWith so many exercises to do, I cant go to the cinema 5. 当不定式的逻辑主语在句中出现时。例如： I have a letter to type today(I是to type的逻辑主语) Do you have anything to say? (you是to say的逻辑主语)6. 当不定式隐含在for sb to do结构中时。This is the best book to read (=for usyou to read)The important thing to do is to lock the door when we leave the house(=for us to do) 7. 一些作表语用的不定式的主动形式。 常见的这类动词有let(出租), rent， hire, blame等。例如：The house is to letI felt I was to blame. Notice 1. 动词不定式主动语态形式的使用要比被动语态形式的使用普遍，有时（尤其在口语中）虽然意思上是被动的，也往往用主动语态形式来表示。I have three motors to repair today.The task is difficult to finish on time.2. 有些动词如want, need, require表示“需要”时,后接不定式的被动形式和接动词-ing的主动形式表达的含义一致。The house needs to be repaired / repairing. Our classroom requires to be cleaned / cleaning per day.五、当堂练习Exercise 2 : Use the words & phrases below to fill in the blanks (Textbook P14) 六、知识梳理和课堂小结: 不定式的被动语态形式： 一般式_ ,表示不定式动词与谓语动词 _发生或在谓语动词_发生。 完成式_, 表示不定式动词发生在谓语动词_。七、 课后作业：1. 复习优化指导P 31 Grammar; 2. 优化指导P32-33. 达标训练I， II.
