I am Li Ming. __Don't__ you __remember__ me?
这道题的第一空也很容易填写do,但是因为题目是“难道...吗”,有一种反问的口气在,所以用don't you... 来构成反义疑问句,起到强调作用.
1、Did you used to be outgoing ? 由答句中的 I used to be outgoing 可以判断出此时的used 是used to的结构,因此问句中应该是借助did,used to保持原样.
2、You used to be shy, didn't you? 这是一句反意疑问句,由答句中的did可以知道问句的后半部分应该要有did,因为问句中前半部分是肯定,所以后半部分要用否定,所以did 后面要加 not.
3、Did he used to have curly hair(卷发)?从答句中的not,以及He used to have straight hair（他过去是直发）可以知道,问句应该是问“他过去是卷发吗?”
He used to play soccer, didn't he?这句话第二题一样,也是一句反意疑问句,由答句中的didn't可以知道问句的后半部分应该要有did,因为问句中前半部分是否定,所以后半部分要用肯定.

不懂可以追问.
