to be是从动词不定式to do过来的，就是把do换成be。
be就是系动词is am, are,was were的原型,当然不同的词组意思也不相同。
例如：
1. have to（不得不）be late for (迟到)
because of the bad weather, i have to be late for school. （由于坏天气，我不得不上学迟到了。）
2. be going to(将要)
I am going to be a techer.我就要成为一名教师了。
To Be No.1也是此句型的省略用法。
3. be doomed to 注定
My life is doomed to be colourful.我的生活注定多姿多彩。
等等，词组不同，语义也不尽相同。
希望对你有帮助
to be一般用在你想表达将来的一种状态时用，比如说I want to be a manager.我想当一名经理。再比如说to be continue...待续....(很多电视连续剧什么会在结尾时有)。用法上，to be一般跟在一个不动词之后，如want to be, would like to be等等，翻译则要根据具体的语境和动词。

其实通常看到to be ,就是用在如：I want to be a teacher ,像这样的，大有成为....的意思
to be 你如果是说 TO的用法 那你就去字典查查。 I want to be a rich man. 我想成为一个富有的人。 按葫芦画瓢
