中考英语状语从句归纳

时间状语从句 要点: 时间状语从句,由以下连词引导: when while as after before as soon as since till /until by the time 在时间状语从句中,要注意时态一致。一般情况下主句是将来时的时候,从句要用一般现在时。 当。。。的时候 mozart started writing music when he was four years old. (当)莫扎特的时候,开始写音乐作品。 当。。。时 he visited a lot of places while he was traveling.他在旅途中参观了许多地方。 在。。。的同时;一边。。。一边。。。 he smiled as he stood up.他一边站起来一边笑着。 在。。。之后 he left the classroom after he had finished his homework the other day. 前几天做完作业之后回的家。 在。。。之前 mr. brown had worked in a bank for a year before he came here. 布朗先生来这之前已经在一家银行里工作一年了。 soon as 一。。。就。。。(主将从现) we began to work as soon as we got there.我们一到那就开始工作。 i will write to you as soon as i get home.我一到家就给你写信。 自。。。以来到现在 表示自过去的一个起点时间到目前(说话时间)为止的一段持续时间。主句一般用现在完成时,从句用一般过去时。 mr green has taught in that school since he came to china three years ago. 自格林先生来中国以来,他就在这所学校教书。 (还可以用作介词,本句从句还可以用短语:since three years ago(自三年前以来)表示。) 8 till /until都可以作连词,连接时间状语,也可以作介词,与其它词构成介词短语,在句中作状语。 they walked till /until it was dark.他们一直走到天黑。 xiao ming didn’t leave home till / until his father came back.小明直到他爸爸回来才离开家。 9. by the time 到。。。为止 (所在句子的主句应用完成时) by the time he gets there , his father has already gone.他到家的时候,他爸爸已经走了。 by the time i got to school, the class had already began.我到校时,已经开始上课了。 难点——as when while的辨析 as when while都表示主、从句动作同时发生,三者差异如下: as 表示“一边。。。一边"的意思 强调两个动作同时进行,并表示对比时 when 1、还可以表示从句动词的动作在主几句动词的动作"之前"或"之后"发生。 2、when=and then; at that moment (正在那个时候)

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 get there.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 English well unless you wo rk 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。

名词性从句总结

划从句的方法的方法:通常从引导词(即空)开始划到往后出现的第二个谓语动词之前 删除法(成分残缺的是名词性从句,不残缺的是的定语从句,状语从句,同位语从句) 引导名词性从句的连接词可分为三类: 连词(5个): that (本身无意义。引导单一的宾语从句时that常可省略,但引导主语从句、表语从句、同位语从句时that通常不被省略) whether,if (均表示“是否”表明从句内容的不确定性) as if ,as though ([1] 均表示“好像”,“似乎”) ◆以上在从句中均不充当任何成分 连接代词(10个): what/ whatever, who/ whoever, whom/ whomever, whose/whosever, which/ whichever 连接副词(7个): when/ whenever, where/ wherever, how/ however, why 1.whether引导主语从句(位于句首时) ,表语从句,同位语从句,不用if (.if只能引导两种名词性从句:宾语从句;不放于句首的主语从句。) 2. whether从句作介词宾语,不用if I’m thinking about whether I should quit my present job.我正在考虑是否辞去现在的工作。 3. if与whether都可以与or not连用,但后面紧跟着or not时只能用whether; 4.在动词不定式之前,只能用whether,不能用if。 I don’t know whether or not to tell her the news.我不知道要不要告诉她这个消息。 5.在容易引起混淆产生歧义的情况下,就不可用if,而须用whether。 6.位于discuss后引导宾语从句时whether They are discussing whether the meeting will be put off.他们正在讨论会议是否会被推迟。 通俗来讲,whether在大多数情况下都可以用,而if则不然,有wether和if时一般选wether 不会有错,但是如果所需的意思是"如果",自然只能选if了 考查名词性从句的语序问题 名词性从一般为陈述句语序(连接词+主语+谓语+其他成分) 但what's the matter、what's wrong 本身为陈述语气,则保持原有语序不变。

外研版英语【初中英语】状语从句知识点总结

外研版英语【初中英语】状语从句知识点总结 一、初中英语状语从句 1.I think you’ll miss the train ________ you hurry up. A.if B.and C.unless 【答案】C 【解析】 【详解】 句意“除非你快点,否则你将错过这个火车”。A.如果(引导条件状语从句);B.和(表示并列);C.除非(引导条件状语从句)。根据句意可知,表示“除非你快点”,故选C。 2.—I’m going to the post office. —________you are there, can you get me some stamps? A.When B.While C.Because D.If 【答案】B 【解析】 试题分析:A. As 一边…一边,作为 B. While当…时候 C. Because 因为 D. lf假如;句意:我将要去邮局。你去那里的时候,能不能给我带一些邮票呢?故选B 考点:连词 点评:连词在中考中涉及到的很多,尤其在宾语从句、状语从句、定语从句中连词是必考点。平时学习过程中,掌握连词的意思,及所表示的关系是至关重要的,这种关系的判断可以通过句子意思的理解来选择恰到的连词。 3.-Have you improved your spoken English? -Not yet.I'll try my best______I am not good at it now. A.so B.although C.but D.until 【答案】B 【解析】 【详解】 句意:——你提高你的英语口语了吗?——还没有.虽然我现在还不擅长,但是我会尽力的.考查连词辨析。A. so所以;B. although 虽然;C. but但是;D. until直到。根据语境推测句意是——你提高你的英语口语了吗?——还没有.虽然我现在还不擅长,但是我会尽力的.在这里两个句子之间存在一个相反的让步关系,though/although/even though“虽然;尽管”,引导让步状语从句,故选B. 【点睛】 本题主要考查连词的用法,连词在句子中主要起联系上下文的作用,他们之间的区别就是表示逻辑关系的不同,所以在解题时先要理解上下文含义,然后根据上下文逻辑关系选择合适的连词.前后句之间是让步关系. 4.You will fall behind others ______ you work hard.
