真实条件句用于陈述语气,假设的情况有可能发生。各种结构参见下表:
句型条件从句主句一般现在时shall/will + 动词原形祈使句情态动词一般现在时
例如:If he comes, he will bring his violin. 如果他来,会带小提琴来的。
典型例题
The volleyball match will be put off if it ___.
A. will rain B. rains C. rained D. is rained
答案B.真实条件句主句为将来时,从句用一般现在时。
注意:
1)在真实条件句中,主句不能用be going to表示将来,该用shall, will.
(错) If you leave now, you are never going to regret it.
(对) If you leave now, you will never regret it.
2)表示真理时,主句谓语动词不用shall (will) +动词原形,而直接用一般现在时的动词形式。
