I'm sorry for not ___(let)you know the good news earily

问题描述:

I'm sorry for not ___(let)you know the good news earily

to let,be sorry to do sth,对做。。。事深感歉意。在不定式to前直接加not表示否定形式

not let

having let/letting
按照非常正统标准的语法用前者,表示抱歉已经发生的事情,由于是已经,所以用完成式
但是在口语中后者也表较常用,表示一种事实

letting
for后面动词用ing

for是一个介词,所以后面的东西必须是名词或者动名词.所以,要用for not letting you know ...其他例子:I'm sorry for being late again.He is happy for your coming to his birthday.Thank you for helping me....
