if引导的条件状语从句
1.引导条件状语从句最常用的连词是if, 意为“如果;假如”, 表示在某种条件下某事很可能发生。如:
If you want to go, please tell me.
If you want to know more about it, please telephone our teacher.
If the red light is on, wait a minute.
在 if 引导的条件状语从句中,if 和条件句位置灵活,可放在句首,也可直接放在主句后面,若 if 条件句放句首,从句后面要加逗号,和主句隔开。如:
Print the text if you like it.
If you like the text, print it.
Look at the blackboard if you can’t remember the words.
If you can’t remember the words, look at the blackboard.
3. 在 if 引导的条件状语从句中,如果从句谈论的是一个有可能发生的事实及其产生的相关的结果,主句用一般将来时态,从句用一般现在时态。如:
We can walk there if we can't find a bus.
If it rains tomorrow, we will not go to the zoo.
What will you do if you find a panda in danger
4.如果 if 条件句谈论的是重复发生和预示要发生的情景和事件,则主从句大多用一般现在时态。如:
If bears are in danger, they attack people.
If you fall into the water and can\'t swim, they may come up to help you.
5. if " 引导的条件状语从句的用法,现在总结一下:
if 条件句不一般,几个要点记心间;
条件句,放在前,逗号要放句中间。
条件句表可能,主句多用将来时;
条件句表事实,主句常用现在时。
if条件句歌诀
if是个连词,含义多多,其中一个含义是“如果”,可以用来引导条件状语从句。if条件从句的主要用法可用下面的口诀来概括:
if条件句不一般,几个要点记心间。
条件句放在前,逗号要放句中间。
条件句表可能,主句多用将来时;
条件句表事实,主句常用现在时。
if条件句有特点,现在时把将来替;
这个规则要牢记!
注释:(1)if引导的条件句位置灵活,可直接放在主句后面。如:
I’ll only stay if you offer me more money.
如果你肯多给钱,我就留下。
此外,if引导的条件句还可直接放在句首。不过,若放于句首,if条件句后面要加逗号和主句隔开。如:
If you go to the party, you will have a great time! 如果你去参加晚会,你将玩得非常开心!
(2)如果if条件句谈论的是今后可能出现的情况,则主句大多用一般将来时。
(3)若条件句谈论的是客观事实,则主句大多用一般现在时。
(4)在if引导的条件状语从句中,通常用一般现在时代替一般将来时表示将来。
条件状语从句(一):主将从现
主将从现指if条件状语从句用一般现在时,主句用一般将来时。
e.g. If it doesn’t rain tomorrow, we’ll go to the Great Wall.
如果明天不下雨, 我们就会去长城.
If you don’t get up early, you will be late for school.
如果你不早点起床, 你就会上学迟到.
If I play games on it, it will go wrong.
如果我用它玩游戏, 它就会坏掉.
这里特别注意if条件状语从句与if引导的宾语从句之间的区别:
He will call you if he comes back. 如果他回来,他会给你打电话。
(此句if表如果,是条件状语从句,所以用主将从现。)
I don’t know if he will come back. 我不知道他是否会回来。
(此句if表是否,相当于whether,引导宾语从句, 所以不遵循主将从现,应根据实际情况选择时态。)
补充:when也有相同的用法。
He will call you when he comes back. 当他回来的时候,他会给你打电话。
(此句when表当…时候,是时间状语从句,所以用主将从现。)
I don’t know when he will come back. 我不知道他何时会回来。
(此句when表什么时候,引导宾语从句, 所以不遵循主将从现,应根据实际情况选择时态。)
条件状语从句(二):主情从现
即主句是含有情态动词的句子,从句仍然是一般现在时的句子。
e.g. If all your answers are right, you can go to Hainan for holiday.
如果你的答案都是对的,你就可以去海南度假了。
You may stay to dinner if you like. 你要是愿意可以留下来吃饭。
