(bare infinitive) To see is to believe. (to-infinitive) T: Ok, let’s look some usages of the infinitive structure

He seems to know the way.

④

The adjective followed by the infinitive structure E.g. I am very glad to see you.

Explanation: ①

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？
