B 一楼的解释应该是对的
B regret 即可做及物动词又可作不及物动词,在此处主要按句意理我对于那些我在本该好好学习却已经浪费掉的日子表示惋惜,强调本该和已浪费.
A 区分what to do 和 how to do ,一般就是看do 后面有没有东西,如果有,就是两者都可,如果没有,就是what to do .how to do 后面要加it的.后面一个空简单,是说“另外的人喜欢'被'留下一个人思考”,强调被动关系.
A 首先是句型：it is +adj.+of you to do sth.表示你这样的做法是怎样的.而动作发生在过去,所以是have left.
A regret to do sth.例句：为...抱歉,遗憾[+to-v][+that]
I regret to say that I am unable to help you.
很抱歉,我爱莫能助.
the news +that 表示特指
D 一楼的解释就够了

B 两个动词不能连用，要选不定式。wake to find醒来后发现
B regret doing 后悔做了某事，should have done本来该做，但事实上没有做
A what to do 该做什么，后面的是被动关系，需要选被动语态
A 前面有was，选完成时
A regret to do很遗憾做某事，
D happen to do碰巧做...

10。A.what to do ,to be left。第一空缺少宾语，应选what to do。how to do本身不完整，应该是how to do sth.。第二个空是被动语态。
11。A.to have left 。it 是形式宾语，真正的宾语是不定式 to have left。
12。A.to tell ,that 。regret to do sth.在此表示遗憾地做某事。第二空是同位语从句，用that引导。
13。D.to be。happen to do 碰巧做某事。当发生火灾时，史密斯一家正好在电影院里。
