条件状语从句的用法及规则(if什么情况下不用主将从现)

条件状语从句知识点总结?

一.if的位置:if“如果”,当引导条件状语从句时,既可以放在主句前面,也可以放在主句后面。若if引导的条件句放在句首,从句后面要加逗号与主句隔开。

例如:My mother will take me to the park if she is free.如果我妈妈有空,她就会带我去公园。

二.时态的运用

注意:在if的条件状语从句中,主句为下列情形之一时,if条件状语要用一般现在时。

1.主句是一般将来时(主将从现)

例如:If he comes, he will tell me all.如果他来了,他会告诉我所有(的事情)。

2.主句是含有情态动词may/might/can/must/should等句子。

例如:If you want to lose weight, you must eat less bread.如果你想减肥,你必须少吃面包。

3.主句是祈使句

例如:If you are not strong enough, please don’t take part in such an activity.如果你不够强壮,请不要参加这种活动

条件状语从句可以位于主句前面或后面。

1、 由if,unless引导

if 表示正面的条件,意为“如果”;unless表示反面的条件,意为“除非,如果不”(if not)

You will be late unless you leave immediately.除非你立即走,否则,你会迟到。

If you don’t hurry up, you’ll be late. 如果你不快点,你就会晚了。

We’ll go there unless it rains. 如果不下雨,我们就去那儿。

2、由suppose,supposing,as/so long as, providing, provided, on condition that和in case等引导

这类连词(词组)意思相近,有:“如果、假设、即使、在……条件下”等意义。

Suppose (Supposing) he is ill, what shall we do? 如果他病了,我们该怎么办?

You’ll do all right, as long as you follow his advice.只要你听从他的劝告,你就会干得很好的。

In case John comes, please tell him to wait.假如约翰来了,请让他稍候。

You may keep the book a further week provided (that) no one else requires it.倘若这本书没有其他人想借的话,你可以再续借一个礼拜。

if引导条件状语从句,翻译成“如果”时主将从现、主情从现、主祈从现。除了这三个还有什么时从句用现在时

  • 我们老师说还有一个,我个人认为没有想出来,请知道的帮助一下
  • 英语高考五三上,有关于if 的详细解读

“if”条件状语从句对“过去的将来”进行假设,其真实条件和虚拟条件在时态上分别遵循什么规则?

  • 即站在过去,“对过去的将来的假设”应该用什么时态?和“对过去的假设”有什么不同?
  • 所谓过去将来,就是指动作或行为还没有发生,只是可能发生,这就是虚拟。如果,动作或行为已经发生,再假设它还没有发生,这也是虚拟。虚拟条件句的时态遵循往前推一步的原则。比如,①. If you had been here, the problem would have been solved.如果你在这,那个问题就会被解决了。(真实情况:you were not here)②. If you were here, the problem could be solved.如果你在这,这问题就可能被解决。(真实情况: you are not here)

根据例子,把下列句子改成if引导的条件状语从句。

  • Example: The girl eats too much. She is getting too fat for her best dress. If you will eat so much, you can’t complain if you’re getting too fat for your best dress!1.Tom smokes a lot of cigarettes. They make him cough. 2.Ben goes out without his raincoat and gets caught in a shower. 3.Keith stays up late drinking in the bar. He feels tired next morning. 4.Mary fails to hand in her homework. She is punished by the teacher. 5.Diana forgets to book a hotel for her holiday and finds nowhere to stay.问题补充: 用will
  • 1 If Tom doesn‘t smoke a lot of cigarettes,he won‘t cough by them2 If Ben goes out with his raincoat,he will not get caught in a shower. 3.It Keith doesn‘t stay up late drinking in the bar,he will not feel tired next morning. 4.If Mary doesn’t fail to hand in her homework,she will not be punished by the teacher. 5.If Diana doesn’t forget to book a hotel for her holiday,she will not find nowhere to stay.

八年级英语(关于if引导的条件状语从句)

  • 1-5 CDEAB

下面这句话中“that”后面到底是宾语从句还是if的条件状语从句?

  • he went over to the workmen and told them that if a pоliceman ordered them to go away, they were not to take him seriously. (告诉他们若有个X来让他们走开,不要把他当回事)若为宾语从句,则该从句做told的直接宾语吗?
  • 句中that引导的是宾语从句,作 told 的直接宾语。就像 tell them a story 的 a story 一样。这个宾语从句本身也是一个复合句,包含一个条件状语从句(if a pоliceman ordered them to go away)。
