语法点拨:if与unless引导的条件状语从句

1.常用引导词:if(如果),unless(除非)。

2.条件状语从句的位置

e.g.If it rains tomorrow, I will stay at home.

= I will stay at home if it rains tomorrow.

如果明天下雨我就呆在家里。

3.if引导词用法

if引导的条件句有:真实条件句和非真实条件句两种。

真实条件句:表示在某种条件下某事很可能发生。

e.g.If you ask him, he will help you.

如果你请他帮忙,他会帮你的。

则)。如果主句是祈使句或含有情态动词时,从句也

初中英语时间状语从句讲解及练习

语法 29时间状语从句 一、什么是状语从句 状语就是在一句话中表示该句子的时间、地点、方式、原因、条件等成分。状语从句就是用一个从 句表示状语。状语从句根据它表达的意思不同,可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等九类。 与状语一样,状语从句的位置比较灵活。既可置于主句之前(通常用逗号与主句隔开),也课置于主句之后(不需要用逗号与主句隔开),有时甚至可以置于主句之中。 二、时间状语从句 1. 主句和从句同时发生,这类从句由从属连词when, while, as引导。 He was hungry when he came home. I was crying while everyone was laughing. As I walked out, he walked in. as, when, while, 的区别 ① as强调从句的动作与主句动作同时发生及持续,具有at the same time的意思 他继续往下谈的时候,越来越兴奋。 as还可以表示一边??一边??,强调从句和主句中两个动作交替进行或同步进行。 他们边走边聊。 as还有“ 随着”的含义 随着春天的到来,天气暖和起来。 ② when 强调动作点的特定时间,具有at the time that 的意思 当老师走进来的时候,我们都站起来了。 ③ while 表示较长的期间,具有during the time that 的意思 当我在这的时候,我很安全。 2.主句发生在从句之前,这类从句由从属连词before, until 引导 ,before 意为“ 在---之前” until 在肯定句中意为“直到 --- 为止”,在否定句中意为“直到 --- 才”。从句既可置于主句前,也可置 于主句之后。 回家之前我必须干完所有的活。

初中英语状语从句及练习题(含答案)合集

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。(as表示“一边……一边”) As you grow, you will know more and more。随着年龄的增长,你会懂得越来越多。 2.till或until引导的时间状语从句 till,until(直到……才):一般情况下两者可以互换,但是在强调句型中多用until。till 不可以在句首,而until可以放在句首。 注意:如果主句中的的谓语动词是瞬间动词时,必须用否定形式;如果主句中的谓语动词是延续 性动词时,用肯定或否定形式都可以,但表达的意思不同。例如: I didn’t go to bed until(till) my father came back.直到我父亲回来我才上床睡觉。(go to bed 是瞬间动词,主句用否定形式) I talked until he came back.我工作到他回来为止 I didn't work until he came back.他回来我这才开始工作 Please wait until I arrived.在我到达之前等我。 3.since引导的时间状语从句

初中英语状语从句知识点总结

初中英语状语从句知识点总结(一) 用来修饰主句中的动词,形容词或副词等而充当状语的从句叫做状语从句。状语从句常用从属连词来引导,与主句连接起来。若置于句末,则前面不加逗号。根据意义和作用,状语从句可分为时间原因条件等几种。下面我们就来分析一下这几种状语从句。 1时间状语从句 时间状语从句常用从属连词when,after,until,as soon as,等来引导。 当主句是祈使句或谓语动词是一般将来时态或情态动词时,其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。 如:Please call me when you getthere.当你到那时,请给我打个电话。 I will write to you as soon as I arrive in Beijing.我一到北京就给你写信。 <温馨提示>since引导时间状语从句表示“自从…以来”,从句中的动词一般表示动作的起点,用过去时;而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为: It has been/is+一段时间+since+过去时。 如:I has been/is three years since we met last time.自从我们上次见面,已经三年了。 2条件状语从句 引导条件状语从句的连词或词组有:if(如果),unless(除非),as long as(只要)等。如果主句是将来时,条件状语从句也用一般现在时来表示。 如:I will stay at home if it rains tomorrow.如果明天下雨,我就待在家。 You can’t learn Englishwell unless you work hard. 除非你努力学习,否则是学不好英语的。 <温馨提示>由if引导的条件状语从句,若从句表达的是与现在事实相反的事实,则常用虚拟语气,即用过去时态表示(如果涉及到be动词,一律都用were)。此时,主句则用过去将来时。

初中英语语法讲解 在中考单项选择试题中,除了时态,名词的考查频率也较高。一般考查以下几点: 一、可数名词与不可数名词 在可数名词与不可数名词上一般出现这样几类,(1)分辨是哪一类名词,并根据结论做选择。(2)可数名词复数的不规则变化。(3)不可数名词的量化表达。所以,考生首先要能够明确哪些是可数名词,哪些是不可数名词。其次,还要知道可数名词的复数的变化规则。可数名词的变化规则一般是在单词后面加-s 或-es,如: 1desk---desks bed---beds piano---pianos hat---hats bag---bags photo---phot os 2bus---buses box---boxes watch---watches brush---brushes 3tomato---tomatoes potato---potatoes hero---heroes Negro---Negroes 4 leaf---leaves knife---knives 5baby---babies family---families 另外,还要记住一些特殊的名词的变化形式,如: Chinese---Chinese Japanese---Japanese Englishman---Englishmen Frenchman---Frenchmen Russian---Russians American---Americans

German --- Germans child---children foot---feet man---men woman---women tooth---teeth goose --- geese deer---deer sheep---sheep 还要掌握不可数名词的量化表达有:a piece of、a bag of、a bottle of、a cup of、a glass of 另外,大家应注意:单数集合名词作主语时谓语动词“数的”变化:单数集合名词如class, police, family, school, group, team等。尽管形式上是单数,意义上都是复数,因此,一般要与复数谓语动词连用,例如: Class Five have a foreign friend. 五班有一位外国朋友。(这里的五班指五班的同学的。) His family are good to me. 他的家人对我很好。(很显然,这里的family指家庭成员。)当上述集合名词着重指“整体”时,意义上则是单数,因此,要与单数谓语动词连用。例如, Our school team often plays well in our city. 我们的校队经常在我们市踢得很好。(这里的team 指整个队,但意义上仍为单数,故谓语动词用plays. 初中英语语法讲解二、名词所有格 名词所有格有两种形式:一是加’s,一种是用of来表示。一般情况

初中英语状语从句

初中英语状语从句 【考点直击】 1. 时间状语从句 2. 条件状语从句 3. 原因状语从句 4. 结果状语从句 5. 比较状语从句 6. 目的状语从句 7. 让步状语从句 8. 地点状语从句 【名师点睛】 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 when got to school yesterday. While he was doing his homework, the telephone rang. As he walked along 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. Let’s wait until the rain stops. We won’t start until Bob comes. Don’t get off until the bus stops. 2. 条件状语从句 (1)条件状语从句通常由if, unless引导。例如: What shall we do if it snows tomorrow? Don’t lea ve the building unless I tell you to. (2)在条件状语从句里,谓语动词通常用现在时态表示将来的动作或状态。例如: I’ll help you with your English if am free tomorrow. He won’t be late unless he is ill. (3)“祈使句+ and (or)+ 陈述句”在意思上相当于一个带有条件状语从句的复合句。例如: Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如: He didn’t come to school because he was ill. As it is raining, we shall not go the zoo. Since you can’t answer the question, I’ll ask someone else. (2)because表示直接原因,语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题,只能用because。
