___you were ill,i wouldn`t have spoken so abruptly.A if i have realizedB had i realizedC did i realizedD should i realize 为什么选B?我觉得A才是对的呀,虚拟语气

必须选Ｂ．had i realized =if i had realized，这是倒装．整个句子是虚拟．用ｉｆ引导可以用倒装．如if i were you可以写成were i you．如果选Ａ的话，时态不对．后面用i wouldn't have spoken so abuptly表示我不会这么唐突地说话．也就是说，实际上我说了．如果我意识到你病了的话，我就不会说，但现在真实的情况是我没有意识到你病了，所以这个假设是和过去的事实相反，因此要用had done,而不是have done

Had i realized you were ill,i wouldn`t have spoken so abruptly.=If I Had realized you were ill,i wouldn`t have spoken so abruptly才是虚拟语气eg:If I had seen you, I definitely would have said hello.（如果当时我看到你的话，我一定会打招呼的。）

是虚拟语气没错，句子的大概意思是这样的，如果我知道你生病了，我就不会那么唐突地说出来了！
