This is the grammar – infinitive structure we will learn this class. Who knows what the infinitive structure is. S: The infinitive structure is the phrase that has “to do sth”. T: Very good, but not always. Infinitive structure has two types. One is to-infinitive, the other is bare infinitive. For example: You cannot do better than go. (bare infinitive) To see is to believe. (to-infinitive) T: Ok, let’s look some usages of the infinitive structure ① Infinitive structure acts as subject.

E.g. To err is human. (subject) It takes me ten days to finish this project. (英语中常用 it 做形式主语, 真正的主语是 不定式) ② Infinitive structure acts as predicate E.g. He is yet to come. (be + to come) The important thing is to save lives. ③ Infinitive structure acts as object. E.g. She likes to play with the child. He seems to know the way. ④ The adjective followed by the infinitive structure E.g. I am very glad to see you. He is eager to win. ⑤ Infinitive structure acts as attribute. E.g. He was always the first to come and last to leave. The next train to arrive was from New York. ⑥ Infinitive structure acts as adverbial modifier. E.g. I stayed there to see what would happen. (doing this with explanation) Step III Grammar 1 T: Now please go through the activity 1 and to find all infinitive structures, then tell us if they give essential or extra information.

been in a sandstorm. To have been caught in a sandstorm was a terrible experience. (Ask students to check the answers) Ask students to finish activity 2&3 then call back the answers. 1.

thunderstorms.

1. to work 2. to learn 3. to tell 4. to be completed 5. to miss 6. to be finished 7. to see

Explanation: ① Some adjectives must be followed by “to”: glad, sorry, lucky, free, sure, likely, able, afraid, willing, ready, anxious, careful, foolish etc. ② have to means“不得不…….” ③ Some verbs must be followed by “to” as objective:like, want, hope,expect,

wish, try etc. ④ Set phrases: so + adj.+ as to; such (…) as to….; … enough (for sb) to….; too……to…; only to…. ( 表示未曾料到的结果) etc. Step IV Grammar 2 T: Please turn your book to Page36. At the beginning of the class, I told you that the Infinitive structure has two types. One is to-infinitive, the other is bare infinitive. Now let’s look at the second type of the Infinitive structure. “but + infinitive” is one of the bare infinitive. Who knows how to use this structure? S: We don’t know.

T: If there is a word “do” before the conjunction “but” we should use bare infinitive. e.g. we have nothing to do now but wait. Tom never does anything but talk. If there is no “do” before the conjunction “but” we should use to-infinitive. e.g. They desired nothing but to succeed. I have no choice but to accept the fact. T: Now, look at the Ex.1&2 on page 36 and find the answers. Possible explanations: 1. We do nothing except to talk. ( 可换成 “but”, 但要去掉 “to”) 2. I have to feel very concerned because I can’t do help. ( 我只能担心,因 为我帮不了你 help 是名词 ) 3. I can’t do anything but wonder what will happen. ( 除了想知道将要发生什 么,我不想作任何事情,言外之意就是,我非常想知道将发生什么事)

1. but 2. think 3. choose 4. complaining 5.love 6. nothing Possible explanations:

1. help vt. 应有宾语,所以判断此句中 help 是名词,完整形式应是 “do help”. 2. 同上 3. chose vt. 又 因 but 后是原型。 4. 因为 but 前有"do” 5. 同 1 6. do 应有宾语 其他结构: ① 口语中 go, come 后可不用 to Go tell her. 去告诉他吧。 Come have a glass. 来喝一杯吧。 ② 在 than 后不带 to I would rather go than stay You cannot do better than go. ③ 在一些固定词组中省去 to hear, make, let, see, 但在被动语态中要加上。 疑问词 why 引导的省略句中省去 to. Why not try again? Step V Homework Complete the exercises 1, 2, 3&4 on Page 85
