比如这个句子 I knew I was bleeding,and I < > get up.
A coudn't B didn't
,我不知为什么,顺便问一下couldn't与didn't的区别,这样我就懂了

我知道我在流血,我起不来了
couldn't表示没有能力 或者不行不允许
didn't就表示那个时候没做什么动作和能力条件没什么关系

前者是表示不能够的意思,强调你的能力,后者只是一般的否定,程度不一样啊!

a 表示能力。b 表示过去的事实

比如这个句子 I knew I was bleeding,and I < > get up.A coudn't B didn't,我不知为什么,顺便问一下couldn't与didn't的区别,这样我就懂了 I knew it was rea WHAT I WISH I KNEW WHEN I WAS 20怎么样 帮我翻译一下这个句子,谢拉I wish I knew how to quit you The next thing I knew was that the police came.这个是同位语从句么?

He knew where I was going.这是什么从句? 状语从句,必须要有主语吗?比如:while I was reading ,my tears came to my eyes .这个句子,状语从句While I was reading 可不可以改成While reading (省略I was)? 比较下面三个英语句子,它们各表示什么意思?1、when i was in high school, you never knew what to expect.2、when i was in high school, you never knew me what to expect.3、when i was in high school, i never knew what to expect. at last 可不可以放在不用过去时的句子里比如at last,I know而不用I knew这样可以吗 I never knew you everything i knew 歌词 When I Knew 歌词 英语虚拟语气,“我真想知道他现在在哪儿.”I wish I knew where he was.I wish I knew where he is.应该用is还是was? 翻译这个句子,I was about 10 years old then.
