I did slept very well last night 错没
问题描述：
I did slept very well last night 错没
答
错了，应该把did去掉。I slept very well last night
答
有点小问题
do或(does, did)+动词原形表强调
所以可以删去did 或改slept 为 sleep
答
错了，应该是I did sleep very well last night
答
没有 did 表示强调
答
应为: I did sleep very well last night. (强调句）或I slept very well last night.。强调句型可以将助动词加上。如：Although I don't like Apple very much, I do have an iPhone 4s. (后半句属于强调句，不加do也没关系。就是一般陈述了。）
答
错了
可改为以下说法：
I did sleep very well last night.或
I really slept very well last night.
答
错了
I slept very well last night
答
恩，应用sleep
