英语问题become,,,,,,,请解释下

Question

将来成为不用become

i will become a teacher.错误
i will be a teacher是对的。为什么？

Answer 1

become 的动词用法
1. 基本文法说明这个动词的意思是「变成~；成为~」(=start to be)，因此后面接的字不是名词就是形容词。例 He became famous when he was only a child. 他在小时候就出名了。
become 之后一般不接不定式表示“逐渐…” (此时可用 come, begin＋不定式)。如：＋不定式正：He began [came] to like English. 他开始喜欢英语起来。
误：He became to like English.
正：He became ill yesterday. 他昨天病了。
误：He became to be ill yesterday.
to do或doing 表示逐渐或开始做某事用come begin代替，而不能用become to do，become doing。
注意：1.become一般不用于“将来成为”的意思。如：

（误）I hope you will become well.

（正）I hope you will get well.

2.become，get也用于天气、社会的发展变化，两者可以互换。

1)Our country is getting/becoming stronger and stronger.

我们的国家日益强大。

2)It's becoming/getting colder and colder.

天变得越来越冷。

Answer 2

两句话都是正确的。
become 可以接形容词或名词作表语。
[V-ADJ] It was becoming more and more difficult to live on his salary.
[V-N] She became queen in 1952.
可参考《牛津高阶英汉字典》，祝进步！

Answer 3

I wanna be a teacher或者说I want to become a teacher. BECOME不与将来时连用
