时态关系
句型: 条件从句 主句
一般现在时 shall/will + 动词原形
If he comes, he will bring his violin.
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,主句谓语动词便不用shall (will) +动词原形,而直接用一般现在时的动词形式。
