由to+动词原形构成。不定式是一种非限定性动词

而非限定动词是指那些在句中不能单独充当谓语的动词

动词不定式在句中可以作句子除谓语之外的任何句子成分

动词不定式的被动形式除了一般形式外还有其完成式和进行式

The book is worth 5 dollars.这本书值 5 美元。The car is worth repairing.那辆车值得一修。

动词不定式作主语时，句子的谓语动词常用单数，把不定式置于句首

To get there by bike will take us half an hour.

用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中

It+be+名词+to do　　It's our duty to take good care of the old.

It takes sb+some time+to do　　How long did it take you to finish the work?

It+be+形容词+for sb+to do　It is difficult for us to finish writing the composition in a quarter of an hour.

It+be+形容词+of sb+to do　It is stupid of you to write down everything (that) the teacher says.

It seems(appears)+形容词+to do　　It seemed impossible to save money.

常用表示客观情况的形容词，如：difficult,easy,hard,important,impossible,necessary 等

常用careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid

在不定式前的sb，可看作其逻辑主语。这一句式有时相当于Sb is+形容词+to do句式

It's kind of you to help me with my English.=You are kind to helpme with my English.

形容词值得，价值·一，只作表语，但是不可单独作表语，后面必须跟名词、代词或动名词

“很值得”只能用 well 来修饰，不能用Very。beworth sth.值„钱;(指行动)值得

有价值be worth doing sth.值得做某事The book is well worth reading.这本书很值得读
