be与become的区别（帮忙,
额,在网上看了看be与become的区别
但是答案都不统一的说.
哪位仁兄能帮我整理下,规定下正确答案呢.
我说的是当be和become都是成为的意思.
我举个例子,
I want to be a doctor.
I become a doctoe.
I be a doctor.
I want to become a doctor.
……虽然很荒谬 但是我真的混了.
请求请求!
感激不尽
很多答案说be是一种结果.而become是一种过程
但是比如 I want to be a doctor这是一种结果对吧
但 I become a doctor或者
I want to become a doctor 也是一种结果啊
