请告诉我区别啊,最好举几个例子

动词不定式(to do)可以作如下几种状语:

1)目的状语
in order to do sth.
to do sth.

2)程度状语(也有说成表示程度的结果状语)
adj./adv. + enough + to do sth.
too + adj./adv. +to do sth.
so + adj./adv. + as + to do sth.(注意不要遗漏as)
such + adj.+ a/an c.n.(单数)/c.n.(复数) + as + to do sth.

3)出其不意/出乎意料的结果
only/never + to do sth.
I arrived at the station only to find the train had left.
对比:预料之内的结果用分词作状语
I slipped, breaking the vase.
4)待办事项
Developing a form to maintain ToDo lists that are persisted in a database.
开发一个表单,保存待办事项清单,它保存在数据库中。
to be
to be其实是不定式的一种形式,to+动词原型构成动词不定式。这是非谓语动词用法的一种。
to be意思为将要 打算成为。比如
Yeah. I have got much pressure in the company. I have tobe wrapped upin my work.
是啊,在公司工作很多压力,我不得不全身心地投入工作。

i want to be an English teacher.我打算做一名英语老师。(这里的to be做宾语)

to be frank, i have no idea where he went.老实说,我并不知道他去了哪里。(这里的to be frank做状语)

二者的区别在于:

to be 是be(am,
