　　英语语法详解动词不定式(三)三、不定式作表语

　　1. 一种情况为主语是不定式(表示条件)，表语也是不定式(表示结果)

　　To see is to believe/ To work means to earn a living.

　　2. 另一种情况主语是以aim, duty, hope, idea, happiness, job, plan, problem, purpose, thing, wish等为中心的名词，或以what引导的名词性从句，不定式表语对主语起补充说明作用

　　12) The most important [A] thing is negociate [B] with them about [C] the future of [D] the plant.

　　四、不定式作定语

　　1. 不定式作定语修饰名词或代词，它只能放在它所修饰的名词或代词后面。这时被修饰的名词与不定式之间有逻辑上的主谓关系

　　2. 动词不定式作定语往往有一层动宾关系，即所修饰的名词是不定式的宾语

　　[C] to do … to talk to[D] doing… to talk
