To see is to believe.It is to do sth. eg. It is easy to work out this problem.It is + adj + for sb to do sth. eg. It is hard for us to learn foreign languages well.It is + adj + of sb to do sth. eg. It is very foolish of the man to believe in fairy tales .It is + n+ to do Eg. It is our duty to protect the environment.2) 不定式作表语预定要发生的动作或将来的可能性He is return from Paris tomorrow.说明主语的内容(aim, duty, idea, plan. Mistake, purpose. Suggestion) Her duty is to look after little animals in the zoo.用于正式的指示或命令Two tablets are taken twice a day.3)不定式作宾语(vt.+ to do)初中阶段常见的只能跟不定式作宾语的动词: agree, afford, choose, decide, expect, offer, pretend, prepare, refuse, want, volunteer, wish, plan, fail, hope，learn 等温馨提示: 有些动词后面要用动词+it (形式宾语) + 宾语补足语 + 不定式(真正的宾语)常见的有feel, find, make, think 等.Eg. She found it difficult to do the work by herself. 4)作宾语补足语(vt. + 宾语 + to do )宾语与用作宾语补足语的不定式构成复合宾语, 二者在逻辑上是主谓关系. 初中阶段常见的有: allow，ask，expect，invite，teach，tell，want，would like，encourage，help, advise, guide 等。 Teachers are always tell us not to play with fire . 5）不定式作定语需位于被其修饰的名词或代词之后。（n.+to do/ pronouns + to do）Eg. Zhang Shan is the first one to go abroad in my village. Only then will I have a chance to achieve my dream. I have something to tell you.温馨提示：不定式和它修饰的动词通常有动宾关系，且这个不定式是不及物动词，它后面就应有必要的介词。Eg. I dont have a partner to practice English with。6）不定式作状语初中阶段学的常用来表目的，结果或原因。enough to do tootoEg.
