he'd拆开是哪两个单词?
he would?he could?怎样区分?

'd 是 did、had 或 would 的缩略形式.如果后面跟动词原形,就是 did 的缩写;如果后面跟过去分词或者 “better + 原形”,就是 had 的缩写; 如果后面是 “rather/like to + 原形”,就是 would 的缩写.例如:


Where'd you go yesterday? 昨天你上哪去了?【= Where did】
 
He'd already left.  他已经离开了.【= He had】
You’d better go away. 你最好走开.【= You had】
 
I'd rather walk than drive.我宁愿步行也不愿乘车.【= I would】
I'd like to go.我愿意走.【= I would】
