Note: keep sb.from doing 中from 不可以省略, 因为keep sb.doing 意为：让某人一直做某事。其他两个词组中from省略后意思不变。

Step 1 Presentation Look at the examples a-f.The underlined phrases are examples of different types of infinitive.a.The wind is strong enough.It can move sand dunes.The wind is strong enough to move sand dunes.b.We were advised, “ Don’t go outside.” We were advised not to go outside.c.I’m cycling to work in a sandstorm and it’s frightening.I’m frightening to be cycling to work in a sandstorm.

eg: He seems to understand what I said I hope to visit Paris again.2.动词不定式的进行式：表示与主动词同时发生且动作正在进行。 eg: The two cheats pretended to be working hard.3.动词不定式的完成式：表示不定式动作发生于主动词之前。 eg: She seems to have seen this film.He happened to have gone out when I went to see him 4.动词不定式的被动式：表示与逻辑主语之间的被动关系。 eg: The meeting to be held tomorrow is about how to stop the pollution.I want to have been told the news earlier. 5 Ⅱ动词不定式的句法功能
不定式的句法功能是做主语，表语，宾语，宾语补足语，主语补足语，定语，目的状语和结果状语，分别给出一个例句 ：
1) To master a foreign language is neceary for a college student.(主语) 2) Your job is to wash dishes.(表语) 3) She promised to give him a chance.(宾语) 4) The teacher told his students to pay attention to their pronunciation.(宾语补足语) 5) I was asked to help him with his leons.(主语补足语) 6) Have you got a pencil to draw pictures with?(定语) 7) Some scientists went to Germany to attend a medical conference.(状语) 8) He was too excited to say anything.(状语) Ⅲ 不定式的复合结构
1)“疑问词+不定式”可以做主语，宾语，表语，同位语。 The problem is how to persuade him to change his mind.2) 带有逻辑主语的结构of/ for sb.to do sth The first thing to do is to clean the room.It is foolish of you to say such words.辨析：⑴ It is + adj.+ of sb + to do sth.;// ⑵It is + adj.+ for sb + to do sth.差别：以上(1)结构中的adj是用来说明主语的特征的，并作其表语; 而结构(2)中的adj是用来说明句中动词的特征的。
Eg: It’s foolish of you to do such things 可转化为：You’re foolish to do such things.但:It’s easy for you to learn English well
6 不可以象上边那样转化。 Step 3 Practice.Ex1.Fill in the blanks with the verbs in their proper forms.1.It\'s very kind of you ________ it for me.(do) 2.My job is ________ the students English.(teach) 3.If you want ________ with us, you should be ready by eight o\'clock.(go) 4.I dare not ________ him about it.(tell) 5.He told me ________ at six thirty.(leave) 6.The children are warned ________ in that lake.(not swim) 7.Before you leave the room, please remember ________ the light.(turn off) 8.You\'d better ________(stay) at home and ________ (do) your homework.9.It\'s too hard ________ (do) it by myself.10.It takes about two hours ________ (get to) the station.11.It\'s time ________ our cla.(start) 12.I have a lot of things ________ you.(tell) 13.I\'m very glad ________ you again.(hear from) 14.The article is not easy ________ .(understand) 15.We didn\'t have time ________ a rest.(to have) 16.I\'ll try ________ that again.(not do) 17.John\'s wish is ________ a writer in the future.(become) 18.I\'d like ________ (go) to the Summer Palace.19.She doesn\'t know whether and when ________ Shanghai in two days.(leave) 20.She is not sure how ________ out the maths problem.(work) 7 Ex2 1.Don\'t forget _________ the letter.A.to send B.send C.sending D.being sent 2.The chair looks very old, but in fact it is very comfortable to _________.A.sit B.sit on C.be sat D.be sat on 3.Is ______ neceary to return the book tomorrow?
