get 和become 都有做连系动词用法,表“变得”,两者有什么区别呢?

“go+形容词”多表示“(从好的状态)变成坏的状态”,
In hot weather,meat goes bad.
He went mad last year.去年他疯了.
Hearing this,she went red.听到这个,她脸红了.
指人的情绪或身体状态的变化,多用become与get,两者可以互换.
Hearing what he said,the teacher got/became angry.
become,get也用于天气、社会的发展变化,两者可以互换.
Our country is getting/becoming stronger and stronger.
It's becoming/getting colder and colder.
become后的名词前有冠词
She became a lawyer.
