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。
初中英语状语从句和练习题(含答案)
状语从句的分类一、时间状语从句时间状语从句表示时间，引导词有：when, while, as, till, until before, after, since等。
时间状语从句的引导词所表示的意思不尽相同，要注意把握不同引导词所表示的不同时间关系，以及它在具体句子中对应的时态、语态等问题。
注意：as（在……时候，因为），since（自从，因为），它们可以引导时间从句，并强调主句和从句的动作同事发生。
并且while有时还可以表示对比。
例如：（1）While my mother was reading the newspaper, I was watching TV.(read是延续性的动词，read和watch同事发生)I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。
（对比）（2）when（当……的时候），引导的从句的谓语动词可以是延续性动词，也可以是瞬间动词。
从句动作可与主语动作同事发生，也可在其后发生。
I was reading a book when she came into my room.(come是瞬间动词，只能用when引导，不能用while)I often missed my home when(while) I lived in NewYork.（live是延续性动词，when可用while代替）（3）when和while的区别还在于：while引导的时间状语从句多用于进行时态，而when引导的时间状语从句多用于一般时态。
While they were talking, the bell rang.正在他们谈话的时候，上课铃响了。
（4）as译作“一边……一边”、“随着……”，侧重主句和从句的动作同时发生。
有时可与when，while通用。
We always sing as we walk.我们总是边走边唱。

A. got 表示一般过去时；B. will get 是一般将来时；C. get 是一般现在时。

(完整版)初中英语状语从句讲解、练习与答案
状语从句状语从句用来修饰主句中的动词，副词和形容词的从句叫状语从句。
根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句，原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。
1. 时间状语从句(1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。
例如：It was raining hard（rain hard 下大雨）when got to school yesterday.While he was doing his homework, the telephone rang.As he walked along（沿着走）the lake, he sang happily.He had learned a little Chinese before he came to China.After he finished middle school, he went to work in a factory.(2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。
例如：I’ll ring you up as soon as I get to New York.I will tell him everything when he comes back.He won’t believe it until he sees it with his own eyes.(3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。
如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。
例如：The young man read till the light went out（熄灭）.Let’s wait until the rain stops.We won’t start until Bob comes.Don’t get off（从下来）until the bus stops.【Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。
八年级条件状语从句讲练（附答案）
八年级条件状语从句讲练（附答案）引导条件状语从句的连接词主要有：if(如果）、unless（除非）或as long as（只要）等。
unless 在意思上等于if...not。
一、条件状语从句用法1、引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。
如:If you ask him, he will help you.如果你请他帮忙,他会帮你的。
If you fail in the exam, you will let him down.如果你考试不及格,你会让他失望的。
另外,if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。
如: If I were you, I would invite him to the party.如果我是你,我会邀请他参加聚会。
2、unless = if...not.除非,若不,除非在……的时候例如：Let's go out for a walk unless you are too tired.=If you are not too tired, let's go out for a walk.Unless it rains, the game will be played.除非下雨,比赛将照常进行。
3、so/as long as只要例句;You may borrow my book as long as you keep it clean.只要你保持书的清洁，你就可以把我的书借去。
So long as you’re happy, it doesn’t matter what you do.只要你高兴，你做什么都没有关系。
二、时态问题在条件状语从句中，要注意“主将从现”的规定，即主句用一般将来时，从句用一般现在时表示将来时。
例句：I will come to see you if I have time. 我有时间，我就来看你。

初中条件状语从句(附答案)(整理)
初中条件状语从句(附答案)(整理)条件状语从句讲解及练习一、考点归纳由连接词if或unless引导的状语从句叫做条件状语从句。
（注意：在含有条件状语从句的复合句中，如果主句是一般将来时态，从句要用一般现在是“主将从现原则”。
通常译作“假如，如果，除非”。
引导词：常用引导词：if , unless1.if引导词用法研究" 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引导的条件句有：真实条件句和非真实条件句两种:（1）真实条件句：表示在某种条件下某事很可能发生。
Eg:a)If you ask him, he will help you.假定你请他协助,他会帮你的。
b)If you fail in the exam, you will let him down.假定你测验不合格,你会让他扫兴的。
c)If it rains tomorrow, wewon’tgo on a picnic.假定明世界雨，我们就不去野餐。
留意：切记紧随着if的那句话是从句。
（2）非实在前提句是虚拟语气的一种，透露表现与究竟相反，不成完成的前提或基本不成能存在的前提,也就是一种虚拟的前提或假定,从句多用普通曩昔时或曩昔完成时。
Eg:a)If I were you, I would invite him to the party.假定我是你,我会约请他加入集会。
b)I would have arrived much earlier if I had not been caught in the traffic.如果没有堵车,我会到的早一点儿。
c)If I were you, I would go with him.如果我是你,我会和他一起去的。
2.unless引导词用法（1）牢固搭配：unless = if...not除非,若不,除非在……的时分。

e.g:If you put wood into water, it floats.如果你把木头放到水里，它就会浮起来。
Unless you keep ice cream in a fridge, it melts.除非你把冰淇淋放进冰箱，不然它就会融化。
二、时态1．当主句和从句所表示的是原理、客观真理、规则时，主句是一般现在时（包括祈使句和含有情态动词can/may/must等），从句也要用一般现在时。
例如：1) 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。
(原理)2)Be careful if you cross the road.(祈使句)3) You must see the doctor if you are ill.( 含有情态动词）2. 在if条件状语从句中，如果从句谈论的是一个可能发生的事实及其产生的相关结果，主句用一般将来时，从句用一般现在时。
e.g:1) If it rains tomorrow, we will not go to the zoo.2) If you go to bed earlier, you won't feel tired in the morning.3. 如果从句用现在进行时或现在完成时，主句需用一般将来时。
