Text
Why did the writer become very worried
Dentists always ask questions when it is impossible for you to answer. My dentist had just pulled out one of my teeth and had told me to rest for a while. I tried to say something, but my mouth was full of cotton-wool. He knew I collected birds' eggs and asked me whether my collection was growing. He then asked me how my brother was and whether I liked my new job in London. In answer to these questions I either nodded or made strange noises. Meanwhile, my tongue was busy searching out the hole where the tooth had been. I suddenly felt very worried, but could not say anything. When the dentist at last removed the cotton-wool from my mouth, I was able to tell him that he had pulled out the wrong tooth.

Questions：
Grammar
(一)动词不定式作定语
Grammar
1.动词不定式作定语的考点集中在动词不定式与被修饰词的逻辑关系的判断上。① He is always the first one to get up.他总是第一个起床。
("the first one"与"to getup”有逻辑上的主谓关系）
② The next train to arrive was from New York.
下一列到站的火车是从纽约开来的。
2.不定式既有动词性质，又有名词性质，它可以有时态、语态的变化，可有宾语和状语并组成不定式短语,也可以用作主语、宾语等。
3. 不定式有两种形式：一是带 to 的不定式，一是不带 to的不定式。后者即通常的动词原形。
Grammar
I like getting up very early in summer. The morning air is so good________
A. to be breathed B. to breathe C. breathing D. being breathed
Grammar
答案解析:B. 题干中后一句可看作是"The morning air is so good for me to breathe.",作状语的动词不定式前后的breathe和air之间虽然是动宾关系,但good后省略了for me,其逻辑主语是1,习惯上采用主动形式。题干的句意为:我喜欢夏天早起。呼吸早晨的空气有益于身心。
1. 主动语态。
1)一般式。由to+原形动词构成,表示该行为或状语与谓语同时或在其后发生。如:The students hoped to do business after graduation.

考题: The crowd cheered wildly as the sight of Liu Xiang, who was reported ________ the world record in the 110-metre hurdle race.
A. breaking B. having broken C.to have broken D. to break
1)一般式。由to be+过去分词构成。
如:The problem remains to be solved. 这个问题还有待解决。
2)完成式。由to have been+过去分词形式构成。
如:He is said to have been hurt in the accident. 据说他在事故中受了伤

（三)动词不定式的否定式
不定式的否定式由 not 或 never加不定式构成。
如：He decided not to do it.他决定不做那件事。
She wished never to see him again.她希望永远不再见到他。

1.在 rather than 与 other than 等之后用不带 to 的不定式。

No one could do other than admite it. 人人都不得不赞赏它。
2. can not but和can not help but之后的不定式一般都不带to。
