河南省八年级英语上册Unit10Ifyougotothepartyyouwillhaveagreattime！解题技巧总结单选题1、—What’s your plan for this Sunday?—If it ________ rain, we ________ fishing.A．doesn’t ; will goB．won’t ; will goC．isn’t ; will go答案：A句意：——这个星期天你有什么计划？——如果不下雨，我们就去钓鱼。
考查if引导的条件状语从句。
go fishing“去钓鱼”，根据if引导的条件状语从句遵循“主将从现”原则，排除B，第一个空后的“rain”是实义动词以及主语“it”是第三人称单数，所以否定形式用助动词doesn’t，排除C，故选A。
2、—Lily is intelligent and hard-working, she ________ do well in the singing competition.—Sure. She was born to be a singer.A．shouldB．mightC．can’t答案：A句意：——莉莉聪明又勤奋，她应该在歌唱比赛中取得好成绩。
——当然。
她天生是个歌唱家。
考查情态动词。
should应该；might可能；can't不可能。
根据答句“Sure. She was born to be a singer.”讲到Lily是天生的歌唱家，可知此处表示肯定的推测，排除C。
might表示推测时可能性非常小，而should表推测时讲话人是根据自己了解的情况和判断，试探性地得出结论，有“按理应当，估计”的含义。
根据题干中“Lily is intelligent and hard-working”可知这里是根据自己了解的情况而做出的推测，用should而不用might。
故选A。
3、You will be able to see something you climb onto those rocks.A．ifB．thoughC．untilD．unless答案：A句意：如果你爬上这些岩石，你就会看到一些东西。
2019年秋人教版八年级Unit 10 if引导的条件状语从句讲和练(含答案及解析)
2019年秋八年级上册单元语法讲与练if引导的条件状语从句语法精讲1.条件状语从句的含义由一个主句和一个或一个以上的从句构成的句子叫复合句。
在复合句中作状语的句子叫作状语从句。
状语从句根据它表达的意思可分为很多种，if引导的句子在复合句中表示条件，作主句的条件状语，因此称为条件状语从句。
If you don’t hurry，you’ll be late.如果你不快点，你将会迟到的。
If he comes，let me know.如果他要来，通知我。
2.if引导的条件状语从句的结构if引导的条件状语从句在句中的位置比较灵活，可以放在主句之前(这时要和主句用逗号隔开)，也可以放在主句的后面(不用逗号)。
条件状语从句的结构为：if+陈述句，主语+谓语(=主语+谓语+if+陈述句)。
意为“如果……就……”。
If you ask him，he will tell you the answer.如果你问他，他就会告诉你答案。
I hope to visit her if I’m free.如果我有空，我希望去看望她。
3.if引导的条件状语从句与主句时态的一致性在复合句中，从句中动词的时态在一定程度上受到主句动词时态的制约，英语语法中称为时态呼应。
（1）在含有条件状语从句的复合句中，如果主句是一般将来时，从句则用一般现在时代替一般将来时表将来。
If it rains，I will stay at home.如果下雨，我将待在家里。
If you study hard，you will pass the examination.如果你努力学习，就能通过这次考试。
（2）如果主句含有must，may，can等情态动词，从句也要用一般现在时。
If you drive too fast，you may have an accident.如果你把车开得太快，你可能会出事故。
You must stop if the traffic light is red.如果红灯亮了，你必须停下来。

【英语】英语状语从句练习题及答案含解析
【解析】
【详解】
句意：——我想知道蒂娜下周是否会来中国。——如果不下雨，她就会来。根据语境推测对话的语境是“——我想知道蒂娜下周是否会来中国。——如果不下雨，她就会来。”，第一个设空处的if意思是“是否”，引导宾语从句，主句是一般现在时，从句根据时间状语next week确定用一般将来时，一般将来时的构成是：主语+will+动词原形，排除B/C；第二个设空处考查含有if引导的条件状语从句中主句的时态，在含有条件状语从句中的复合句中，时态遵循“主将从现”的原则，即：主句用一般将来时，从句使用一般现在时表将来，表示“不下雨”应借助于助动词does，故选D。
8．It is necessary for children to exchange ideas with parents from time to time ________ a good parent-children relationship could be set up.

一I finished the project.
A．UntilB．WhileC．WhenD．Not until

八年级英语 if条件状语从句及巩固练习答案
八年级英语if条件状语从句+巩固练习概念引入英国前首相撒切尔夫人（Margaret Thatcher）曾用if条件句对男人和女人进行评价：In politics, if you want someone to make a speech, ask a man; if you want something done, ask a woman.在政治领域，如果你想要有人发表演说，那就找男士去；而如果你想真正把事情解决，那就找女士。
用法讲解一、概念连词if的意思是“如果”，它引导的句子表示某事发生所需要的条件，即“在……条件下某事才能发生”，在句子中充当状语，因此我们称之为条件状语从句。
在复合句中连词if引导的句子为从句，被修饰的句子为主句。
从句可以放在主句后，也可以放在主句前，从句放在主句前时，应用逗号将它与主句隔开。
例如：We’ll go to the Great Wall if it doesn’t rain tomorrow. = If it doesn’t rain tomorrow, we’ll go to the Great Wall.如果明天不下雨，我们就去长城。
二、用法1. 条件状语从句通常由连词if引导，意为“如果，假如”，主句不能用be going to 表示将来，而应该用shall或will。
例如：If I’m free tomorrow, I’ll go with you.如果我明天有空，我将会和你一起去。
2. if引导的条件状语从句，主句用一般将来时，从句则用一般现在时，即“主将从现”。
例如：If it is sunny tomorrow, I’ll climb the hill.如果明天天气晴朗，我将去爬山。
3. 正确区分if引导的条件状语从句和if引导的宾语从句。
在条件状语从句中，if表示“如果”；而在宾语从句中，if表示“是否”。
可以用下面的方法区分：1) 从句前置法：if引导的条件状语从句，可以放在主句之前并用逗号隔开，也可放在主句之后；而if引导的宾语从句只能放在主句之后。

牛津版沪教版英语八年级(上)Unit7Memory语法讲解+练习+答案
牛津版沪教版英语八年级(上)Unit7Memory语法讲解+练习+答案Unit 7 Memory语法讲解：条件状语从句，if…not=unless由引导词if或unless引导的状语从句叫做条件状语从句。
在英文中，条件是指某一件事情实现之后（状语从句中的动作），其它事情（主句中的动作）才能发生，通常译作“假如”。
从句的位置可在主句之前或之后（从句在前，一般需要用逗号与主句分隔）。
一、if引导的条件状语从句条件状语从句最常用的引导词是if（连词）。
（1）主现从现构成：主句（一般现在时态）+ if从句（一般现在时态）用法：讲述自然规律，肯定会发生的事情或客观事实。
例如：If you take a fish out of water, it dies.如果把鱼从水中拿出，它会死。
If you put a piece of paper into water, it gets wet.如果你把一张纸放进水中，它会变湿。
If you put salt into water, it disappears.如果你把盐放入水中，它会消失。
If you heat ice, it turns into water.如果你加热冰块，它会变成水。
Steam turns into water if you cool it.如果你冷却水蒸气，它会变成水。
Oil floats if you pour it on water.如果你把油倒入水中，它会漂浮。
（2）主将从现、主祈从现、主情从现组成：主句（普通未来时态、祈使句、神态动词）+ if从句（普通目前时态）用法：评论未来大概会产生的情形。
比方：①I’ll buy a car if I have enough money.假如我有充足的钱，我会买一辆车。
They won’t go out if it rains heavily tomorrow.假如明世界大雨，他们不会外出。
②Be careful when you cross the road.过马路时要谨慎。
