If it (rain)__last night ,the ground would be wet and the temperature would be low today.
题目
If it (rain)__last night ,the ground would be wet and the temperature would be low today.
用词正确形式填空求解.此句有 If.would be..虚拟语气里面的 主句用would do,If从句应该用一般过去式的,表示现在事实相反.我本来用rained.但是书上答案是had rained,如果这么用后面主句应该用would have done啊.
答案
该题为虚拟语气的错综时间条件句
前句是对过去的虚拟,后句则指现在的情况
如:If you had taken the medicine according to the doctor's advice,you would be well now.
当主句中有now,today等表示现在情况的词时,就依情况来定
