(错误) If you leave now, you will never regret it. (正确) (2) if “如果”, 引导条件状语从句, 主句用一般将来时, 从句则用一般现在时，如： If it rains tomorrow, I shan’t climb the hills. 注意: 宾语从句中的if与条件状语从句if的区别。 宾语从句中的if“是否”相当于whether, 引导宾语从句, 时态需根据语境确定。 I don’t know if it will rain tomorrow. 我不知道明天是否会下雨。 要注意这种带“will＋动词原形”的if-分句在某些场合是不可以随便用的, 比如我们可以说： If he gets my letter in time, he’ll be able to change his plans. 如果他及时收到
