16.1 真实条件句
真实条件句用于陈述语气,假设的情况可能发生,其中if是如果的意思。
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。
