Question

‘if’翻译做“如果”和“是否”句中都用主将从现的形式么?

Answer 1

不要这么绝对.
当做"如果"的时候,在不是虚拟语气的情况下,主将从现.比如
I will go climbing the mountains if it is not rainy tomorrow.
(明天不下雨,我就去爬山)
做"是否"的时候,和主句一致.比如
I don't care if he comes.
(我不在乎他是否来)
当"如果"是虚拟语气的时候,主句与现在事实相反,从句用would/情态动词过去式+do /were (不分人称) /did,比如
If the doctor had been available a little earlier,the child could not have died.
(假如医生能早到一点点,那小孩不会死) 实际是死了
