D
I have no idea =I don't kmow
由句意理解,我不知道他是否/何时/为何会放弃帮助.前三项皆可,if只有“如果”的意思,放入句中不符.
kidcoat看反题意了

A. 串错字!应该是whether

选A。由题意知选whether或if,排除B、C,又因为这是同位语从句(同位语从句学过吧?),故只能用whether而不能用if引导从句,排除D。故选A。

C
如果a是笔误的话。Why he will...不可理解。

if

C.why
AD 意思是我不知他是否会放弃……
C是我不知他什么时候会放弃……
而用C应该是I have no idea why he gave up ……通常是我不知他为什么放弃了……

if 虽然也有是否的意思,但这是同位语从句,只能用whether
