一、条件状语从句的定义和基本结构
条件状语从句是用来表示主句动作发生的条件的从句。在初中英语中,if引导的条件状语从句是重点。其基本结构是“if + 从句(一般现在时),主句(一般将来时)”。这是一种“主将从现”的原则,即从句用一般现在时表将来,主句用一般将来时。例如:If it rains tomorrow, I will stay at home.(如果明天下雨,我就待在家里。)
二、详细讲解
1. if从句中的动词形式
- if引导的条件状语从句中,当从句描述的是一个客观事实或经常发生的情况时,从句也用一般现在时。例如:If you heat ice, it turns into water.(如果你给冰加热,它就会变成水。)
- 即使主句是祈使句或含有情态动词,从句依然遵循“主将从现”的原则(祈使句和情态动词本身就有将来的含义在里面)。例如:If you see him, tell him to come to my office.(如果你见到他,告诉他来我的办公室。);If you want to pass the exam, you must study hard.(如果你想通过考试,你必须努力学习。)
2. 位置关系
- if引导的条件状语从句可以放在主句之前,这时从句和主句之间要用逗号隔开。例如:If you come early, you can get a good seat.(如果你来得早,你可以得到一个好座位。)
- 也可以放在主句之后,这时不需要逗号。例如:You can ask me for help if you need it.(如果你需要帮助,你可以向我求助。)
3. 真实条件句和虚拟条件句(初中阶段简单了解)
- 我们上面讲的大多是真实条件句,即假设的情况是有可能发生的。虚拟条件句表示与事实不符的假设,初中阶段简单了解即可。例如:If I were you, I would choose the red one.(如果我是你,我会选择红色的那个。)这里的“我是你”是与事实不符的假设,在虚拟语气中,be动词要用were。
