Become和come into being在用法上存在差别。

1. Become通常指个人或事物状态的转移或变化，表示某种变化的结果，比如：I have become a teacher.（我已成为一名教师）。

2. Come into being则表示事物或现象的开始，常用于说明某些事情从无到有的过程，表示一个事物的形成或开始，例如：The world has come into being for billions of years.（世界已形成了数十亿年）虽然在用法上有所区别，但在某些情况下两个词可以互换使用，表达近似的意思。

come into (verb,动词） 走进来 ，进入, 得到, 继承,取得

e.g. # To come into effect

生效

# Come into my office.

到我办公室里来。

# Come into the warm.

进到暖和的地方来。

# To come into existence.

发生使出现（存在）

# come into being; become reality.

形成产生；成为现实。

# come into existence through birth.

# come into fashion; become fashionable.

流行起来；变得流行起来。

# Come into possession of sth.

依我看来，并没有所谓的“become into"，因为become已包含into的意思。
