come 和 go 都可用作连系动词，表示事物状态的变化。
The handle has come loose. 这个把柄松了。
This envelope has come unstuck. 这封信开了。
Wrong never comes right. 错的永远不会变成对的。
Your shoe-laces have come undone. 你的鞋带散了。
The package is about to come unwrapped. 那个包快散开了。
The children went wild with excitement. 孩子们欣喜若狂。
She went pale at the news. 听了这消息她脸色变得苍白。
He went mad in the end. 最后他疯了。
Fish soon goes bad in hot weather. 大热天鱼很容易坏。
The children must not go hungry. 孩子们不应挨饿。
两者之后所接形容词通常各有其特点，有时还可从好坏方面去区别：即 come 用于“好”的变化，go 用于“坏”的变化(也多指由强到弱的变化)。如：
The meat has gone bad. 这肉变味了。
Something has gone wrong with the radio. 这收音机什么地方出了毛病。
Things will come right. 一切会顺利地进行。
Her dream has come true. 她的梦想实现了。
表示人的生理变化通常用 go。如：
go blind 变瞎
go deaf 变聋
go grey 两鬓渐白
go bald (deaf,insane,etc) 变秃,变聋,发疯
但是 go 通常不与 old, ill, tired 等连用。
另外,go还可用于人或事物颜色的变色,与turn用法相同：
She went [turned] blue with cold.她冻得脸色发青了.
The rotten meat went [turned] green.这块腐烂的肉变绿了.
【注】① 但是 go 一般不与 old,tired,ill 等连用,遇此情况要用其他连系动词：grow [get] old 变老,fall [become] ill (sick) 生病,get [feel] tired 疲劳
② go后接形容词通常表示的结果(见上例),在个别搭配中也表示现状：go hungry 挨饿,go naked 光着身子
③ come 除表示向好的方面变化外,还有以下常见搭配值得注意：come untied 解开,come loose 变松,come undone 松开
3.以上连系动词通常接形容词作表语,但有的还可接其他结构,如come,get后可接不定式,become,turn后可接名词,get,grow后可接介词短语：
You’ll soon grow to like her.你很快就会喜欢她的.
It’s becoming a serious problem．它正在成为一个严重问题.
They went out of fashion years ago．它们好多年前已变得不时新了.
【注】turn后接名词时,往往表示意想不到的变化,名词前通常用零冠词：
He turned writer after he graduated from a medical college.他从医学院毕业后当了作家.(比较：He became a writer after graduating from college.)
