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。

if引导的条件状语从句在中考题中的简单剖析-最新教育文档
if引导的条件状语从句在中考题中的简单剖析if引导的条件状语从句是初中英语教学的一个重要知识点和难点,也是困扰初中生英语学习的一个亟待解决的问题。
通常是考试命题的热点。
但其有章可循,若能将其分类,并从概念、特点、主从句谓语关系入手,此问题便可迎刃而解。
条件状语从句初中英语特点问题一、前言从总结各地历年的中考题来看,if引导的条件状语从句是每年中考命题的一个主要知识点,从未回避过。
非但如此,在试卷中所占的分数比例也非常大,低的时候4或5分,高至10分以上。
但是根据调查和了解,这个知识点不仅成为学生失分的重要地方,而且也是教师教学效果不佳的教学内容方面之一。
其实,如果我们仔细地统计和分析一下多年来这个知识点在中考题中命题的方向、出现形式、考查的重点和所占的比例等,就不难发现在初中阶段学生应掌握的有关if引导的从句知识并不多,而且都是有规律可循。
if引导的条件状语从句从根本来说,可以分为两大类,一类是真实性条件状语从句;一类为非真实性条件状语从句。
非真实的也就是我们部分老师平时所称的虚拟语气。
在初中阶段,真实性条件状语从句是学生掌握和中考考查的重点,非真实性的只需要掌握其中的一个方面,考查的频率相对较弱一些。
二、if引导的真实性条件状语从句1.概念真实性条件状语从句说简单一些就是从句所表达的情况,是实现主句所表达情况的条件,而且从句表达的情况一定是通过努力可以实现的。
例.We won’t go to the beach if it rains tomorrow.2.特点一般情况下,无论是主句还是从句都用陈述语序。
3.主句与从句的谓语关系在真实性条件状语从句中,主句和从句的谓语关系有下列三种情况,我们一般将其总结为主将从现、祁使从现、情态从现。
(1)主将从现,即主句用一般将来时,从句用一般现在时例1.If Maryhas (have) time next weekend, he will go to the zoo.从句谓语主句谓语译文:如果玛丽下周周末有时间,她将会去动物园。
