初中英语复合句
初中重点语法 从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。（参见以下各条） 3、各从句在句子中的位置以及用法： (1) 表语从句：在句子中作连系动词的表语的从句,它位于主句中的系动词之后。 例如：That is why he did not come to school yesterday. / It is because you are so clever. (2) 宾语从句：在句子中作及物动词或介词的宾语。 ①基本形式：（主句＋）连词+从句主语+从句谓语+... ②关于宾语从句连词的选择： 若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略; 若从句来源于一个一般疑问句,连词则用if 或whether; 若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等) 例如：They believe that the computer will finally take the place of human beings.(他们相信计算机终将 代替人类。) (从句本来就是陈述句)/ I wonder whether I should say something for him to the headmaster.(我不知道是不是该为他在校长跟前说点什么。) (从句来源于一般问句Shall I say something for him to the headmaster?) / He asked me where he could get such medicine. (他问我在 哪儿能搞到那样的药。) (从句来源于特殊问句Where can he get such medicine? ) ③宾语从句的时态问题：如果主句是现在时,从句则用现在某一时态,甚至可以用过去时； 如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。如：I think I will do better in English this term. (我想本学期我的英语会学得好点。) / The teacher asked the boy if the earth is round. (老师问那个男孩地球是不是圆的。) ④下列结构后面的从句一般也作为宾语从句看待： be sorry / afraid / sure / glad +that从句,如：I’m sorry I’m late. (对不起,我迟到了。) / I’m afraid he isn’t in at the moment. (恐怕他此刻不在家。) (3) 状语从句：在复合句中作状语,其位置可以在主句前或主句后。状语从句可以分为时间、地点、原因、 目的、结果、比较、让步、条件等几种。状语从句由从属连接词引导。 时间状语从句通常由when ,as ,while, after, before, since, as soon as ,since, till (until), while, whenever 等引导。时间状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该 用现在时替代。如：When you finish the work, you may go out to play with Sam. (你完成工作就可 以出去和Jim一起玩了。) / I won’t leave until Mum comes back. (妈妈回来了我才会走。) 地点状语从句通常由where, wherever等引导。如：Go back where you came from! (哪里来还滚到哪里去！) / I will never forget to catch the thief who stole my necklace wherever he may be. (我永远也不会 忘记去抓住那个偷我项链的贼,无论他会在哪里。) 原因状语从句通常由because, since, as等引导,一般放在句首或句尾。如：He went abroad because his father had found a good university for him. (他出国了,因为他父亲给他找了一所好大学。) 目的状语从句通常由so that..., so...hat..., in order that...等引导,往往放在句尾,从句中通常含有can / could / may / might等情态动词。如：He got up earlier so that he could catch the first train. (他起身 更早为的是赶上第一班车。) 结果状语从句通常由so that..., so...that... 等引导,放在句尾。结果状语从句一般表示已经发生的事情,故多为过去时态。如：He lost so many bikes that he decided never to buy a new one. (他丢了那么多 辆自行车,他决定再也不买新车了。) 比较状语从句通常由as, than, as (so)...as等引导,一般省略从句的谓语部分,只剩下名词或代词(用主格或宾格均可)。如：Jane is much taller than I/me. (Jane比我高多了。) / I don’t have as many books as you (do). (我书没有你多) 让步状语从句通常由though (although), as, even if( even though), however, whatever等引导。如：Even if you pay the debt(债务) for me, I will not thank you because it has nothing to do with me. (即使你替 我还了债我也不会感谢你,因为它与我毫无关系。) / He wears a T-shirt though it is very cold. (他穿 了一件T恤衫,尽管天很冷。)
用合并句子法讲解定语从句
用合并句子法讲解定语从句 定语从句是高中英语教学中重要的语法部分，同时也是为下一步学好其他从句（名词性从句）打好基础。但在实际英语教学中，学生因为对英语句子成分没有清晰的概念，所以导致对定语从句知其然而不知其所以然。在教授定语从句时，应先从句子成分入手，使学生先了解什么是定语，然后在利用合并句子的方式解析定语从句是如何构成的，并引出引导词的使用方法。 一、什么是定语 句子中修饰名词或代词的成分叫做定语。定语可以由形容词，名词，不定式，分词，动名词或从句来充当。 eg: I bought an (expensive) computer. （形容词） I met someone( funny) on my way to school. （形容词）（修饰不定代词的定语后置） she is an( English) teacher. （名词） I have a lot of work( to do). （不定式） The book( written by Tom) is very popular now. （过去分词短语） We can see the (rising) sun. （现在分词）= the sun is rising. He is in the( reading) room. (动名词) = the room for reading The boy (who broke the window)is Tom’s brother. （从句） 二、定语从句 两个术语：先行词，关系词 先行词：被修饰的名词、名词词组或代词 关系词（关系代词或关系副词）：连接先行词与定语从句的词。 关系代词有：who, whom, whose, that, which等；关系副词有：when, where, why等； 1、关系词在定语从句中充当主语 先行词为人时 （1）两个单句为The boys are from Class One. The boys are playing football. （2）第一句为主句，第二句为从句，将两个单句合并为一句。 The boys（the boys are playing football）are from Class One. (3) 括号中句子里的主语the boys, 和先行词是同一个词，应该用关系词替换从句中重复 的the boys. The boys 在从句中作主语，关系词中能作主语并代表人的是who, that The boys（who\that are playing football）are from Class One. (4) who\that==the boys, 在定语从句中做主语的成分，并连接先行词和定语从句。 先行词为物时 （1）I found the letter. The letter came yesterday. （2）I found The letter( the letter came yesterday). （3）用关系词替换从句中重复的the letter, 关系词中能作主语并代表物的是which, that I found The letter(which\that came yesterday). （4）which\that==the letter, 在定语从句中做主语的成分，并连接先行词和定语从句。 2. 关系词在定语从句中充当宾语 先行词为人时 （1）The man is my friend. You met the man just now
(九) 复合句——状语从句
（九）复合句——状语从句 (九) 复合句——状语从句 说明: 所有相关复合句的综合练习将出现在“从句综合练习”章节 考点归纳 1. 状语从句的类型: 时间状语从句、地点状语从句、原因状语从句、条件状语从句、目的状语 从句、结果状语从句、让步状语从句、比较状语从句、方式状语从句 2. 时间状语从句: ⑴ 连接词及固定搭配: when, while, as, since, after, before, until / till, once, each time, every time, any time, whenever, as soon as, the moment, the minute, the instant, hardly / scarcely / barely / rarely … when / before, no sooner … than, just as, directly, immediately, instantly, shortly after, soon after, it won ’t be long before, by the time, it ’s the first time that, it ’s … since, the first time, the last time ⑵ as soon as 与hardly … when 等结构都能表示“一……就……”，但两者的时态不同；前者一般主从句均为一般时态，表示一般情形遵从主将从现原则；后者一般主句为过去完成时，从句为一般过去时，且在句首引起倒装 ⑶ 特殊地，可用the minute, each time, the first time 等名词或名词短语充当连接词引导时间状语从句，该类词称为边际从属连词 3. 地点状语从句可由where, wherever 引导，前者指特定地点，后者为无特定地点 4. 原因状语从句: ⑴ 可由because, since, now that, as, in that 引导，注意for, so, with + n . + 宾补结构 ⑵ 现代英语中，because 与for 都可引导原因状语从句，且都能表示“直接理由”与“间接理由”，如It must be very late, for the streets are quite deserted. (间接理由) 上句中的for 实也可替换为because ，只是在两者同时存在时，使用for 语势较弱，更显出说话人的推断的不确定性，说明说话人的推断略显主观臆断 ⑶ 在表述直接理由时，because, since, as 从句位置既可在主句前，也可在句尾；而for 则只能位于主句后；此外，because 可回答why 问句，because 前可加入诸如simply 的修饰语，because 从句也可作为强调句的强调部分，这些场合下because 不能替换为for ；若because 也表述的是间接理由，则其位置只能在主句后 5. 条件状语从句的连接词及相关搭配: if, unless ( if … not), on condition that, given that, as / so long as, suppose that, even if, even though, provided that, in case, lest, given that, considering that, since, now that 等 6. 目的状语从句可由that, in order that, so that, for the purpose that, in the hope that 等作连接词或 固定搭配，常与情态动词连用 7. 结果状语从句: ⑴ 连接词及固定搭配: that, so … that, such … that, so that 等 ⑵ such 修饰名词，so 修饰形容词或副词，such / so 结构类似于what / how 的固定结构；当 such 修饰可数名词单数时可将其与so 结构互换；若such 修饰不可数名词或可数名词复数时则无法互换 ⑶ 当many, few, little, much 表多少修饰名词时只能用so ；若little 不表多少，且修饰可数名词单数时只能用such 8. 让步状语从句: ⑴ although, though, as, while, even if, even though, however, whatever, no matter 系列等 ⑵ though 引导的让步状语从句可以倒装(也可不倒装)，作用相当于as (必须倒装)，此时though 不能与although 替换；though 与although 都不能与but 并存，却能与yet 并存；as 引导让步状语从句时，倒装形容词、副词及无冠词的名词；只存在even though ，而无 *even although ；though 也可作连接性状语，而although 不可，如He said he would come; he didn ’t, though . ⑶ -ever 系列与no matter 系列的区别(见前) 9. 比较状语从句(见第一章，此略) 1 2
宾语从句练习
宾语从句 1.引导词：1)从句是陈述句引导词加that;2)从句是一般疑问句引导词加if/whether;3)从句是特殊疑问句引导词用特殊疑问词;4)从句是祈使句变为ask/tell sb to do sth. 2.时态：主过从过,主现从不变,客观真理不变。 3.语序：陈述语序(主语在前，谓语在后）。 4.人称：一随主、二随宾、第三人称不更新。 5.当从句是特殊疑问句且主从句的主语一致时，从句能够简化成“疑问词＋不定式结构”。 一、单选 1.Have you decided ________for Australia?

(完整版)状语从句在复合句中作状语
状语从句在复合句中作状语， 修饰动词、形容词或副词等。 状语从句可以表示时间、 条件、原因、 地点、目的、结果、让步、方式、比较等意义。 知识梳理：提纲挈领，抓住重点和难点！ 各类状语从句连接词(短语)一览 表： 时间 条件 If, unless 原因 As, because, since 地点 Where 目的 So that, in order that 结果 So that, so …that, such …that 让步 though, although, even if, however 方式 As 比较 than, (not)as … as, 时间状语从句： Whenever he comes, he brings a friend. 条件状语从句： As long as I am alive, I will go on studying. 原因状 语从句： Since we live near the sea, we enjoy nice weather. 由于我们住在海边 地点状语从句： Put it where we can all see it. 把它放在我们都能看到的位置。 当……时候#, 但用法有区别 : ① when 意为#在……时;当……时#,可表示#点时间#或#段时间#,从句谓语可以是终止性动词，也可以是延续性动词。 例如: When I got home, he was having supper . ② as 意为#边??…边……#或#与??…同时#,重在表示两个动作同时发生。伴随进行。 as 从句是终止性动词时，主句通常 也必须是终止性动词。例如 : They sang as they danced. ③ while 只可表示#段时间#,从句谓语只限于延续性动词。例如 While I was sleeping, my father came in. 注:从句谓语是持续性动词时，when 、while 和as 可以互换？主?从句谓语都是终止性动词时，when 与as 可互换？从句谓 语表示状态时 , 通常用 while 。 2. 引导原因状语从句的连词 原因状语从句一般由 because ， since ， as ， for 引导?注意 as ，because ，since 和 for 的区别 : ① 如果原因是构成句子的最主要部分 ，一般用because 。because 引导的从句一般不放在句子的开头。例如 ： when, while, as, as soon as, since, until, after, before 他每次来都带个朋友。 只要我活着， 我就要学习。 ，能享受到好的天气。 目的状语从句： Finish this so that you can start another. 结果状语从句： He was so angry that he couldn't say a word. 让步状语从句： Though he is in poor health, he works hard. 方式状语从句： Students do as the teachers say. 比较状语从句： The work isn't as easy as I thought. 状语从句的考查点 状语从句是中考词汇和句法部分考查的重点内容之一。 法。现就主要考查点简述如下 : 1.引导时间状语从句的连词 主要有 when, while, as, by the time, before, after 把这个做完，你可以开始另一个。 他气得说不出话了。 虽然他身体不好，但是他工作很努力。 学生们按照老师说的去做。 这项工作比我想象得难。 在复习状语从句时 ,主要任务是弄清楚引导各种状语从句的连词的用 , since, till/until, as soon as 等。其中 when?while 和 as 都可表示 #

宾语从句专题复习
宾语从句专题复习 【复习内容】宾语从句考点归纳 【复习目标】 1．掌握引导宾语从句的各种连词 2．掌握宾语从句的语序──主句+连接词+主语+谓语 3．掌握宾语从句，主句与从句在时态上的呼应。 【重点】语序和时态呼应 【难点】语序和时态呼应 【考点梳理】 一、概念：句子的宾语一般由名词、代词、动名词或动词不定式充当，当一个句子充当宾语时,我们把这个句子叫做宾语从句。 宾语从句的三要点：1、引导词2、从句语序3、从句的时态二、宾语从句的连接词 1．连词that，只起连接作用，在从句中不作句子成分，也无词汇意义，在口语中常被省略。eg. I am afraid（that）you are right. 2．连词if 、whether，它们起连接作用，在从句中不作句子成分，作“是否”解，在口语中多用if。 eg. Tom don't know if/whether his grandpa liked the present. He asked me whether or not I was coming. 引导宾语从句时只用whether不用if的五种情况. （1）后面紧跟or not时。如：I want to know whether or not it is big enough. She asked whether Tom was at home or not. （2）whether引导的从句居句首时。如： Whether my father agrees me or not, I must do that. （3）从句位于介词后作介词宾语时。如： I don`t care about whether he is friendly to me. （4）放在不定式前，与不定式组成词组时。如： The question is whether to go or stay. （5）当主句的谓语动词是discuss等时。如： They are discussing whethere they should sell the old house. 3．连接代词who, whom, whose, what, which，连接副词when, where, why, how，它们起连接作用，作句子成分，各有自己的意义。eg. 1. He asked ______________________________. (谁能回答这个问题） 2. Do you know__________________________. （他们在等谁） 3. He asked ____________________________________________.（谁的书法是班上最好的） 4. Please tell me ____________________________. （我们什么时候开会） 5. Can you tell me ______________. （他在哪儿） 6. Could you tell me ____________________________. （我该怎么去站） 7. Would you tell me ____________________.（为什么火车迟到了） 三、宾语从句的语序 宾语从句的语序是陈述语序，即“连接词+主语+谓语+其它成分”。特别强调：它的主语和谓语的语序是陈述语序，而不是疑问句的倒装结构。 Can you tell me who（m）do we have to see?（╳） Can you tell me who（m）we have to see?（√） The teacher asked the students what they were doing.（思考: what在从句中的成分） 陈述句变为宾语从句时,要注意人称和时态的变化,语序不变。eg. She said, “I will leave a message on the desk.”→She said she would leave a message on the desk. 四、宾语从句的时态呼应 宾语从句中谓语动词的时态，常常受到主句谓语时态的制约，此为时态呼
中考英语语法复合句
人教版中考英语专项练习复合句 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。主句为句子的主体，从句只是做句子的一个成分。根据从句在句子中的作用，可以把从句分为名词性从句（主语从句，宾语从句，表语从句和同位语从句），定语从句和状语从句（时间，地点，原因，条件，让步，方式，比较等）三类。 一.宾语从句 1.宾语从句根据引导词的不同分为三种类型 ⑴由that引导的宾语从句，其中that不做成分，可省略。 We all knew (that) we should learn from each other. ⑵由if/whether引导的宾语从句。 Please tell me if/whether you have been to America. ⑶由who,where,how等连接代词或连接副词引导的宾语从句。 Can you tell me how I can get to the nearest post office? 2.宾语从句“三关” ⑴引导词关 注意：whether与if的区别 只用whether的情况 ①在介词后面 We don`t think about whether it would rain the next day. ②在动词不定式前 They asked me whether to sit at the front. ③当与or not连用，或提出两种选择时 Mary asked whether I was
doing my homework or not at that time ④宾语从句提前时 Whether this is true or not, I can`t say ⑤在动词discuss后的宾语从句中 We discussed whether we should have a sports meeting next week. ⑥引导表语从句或位于句首的主语从句用whether The question was whether he went there last night 只用if的情况 ①引导否定概念的宾语从句时 He asked me if I had`t finished my homework ②引导条件状语从句时，if意为“如果” We`ll go hiking if it doesn`t rain tomorrow ⑵语序关 ①宾语从句若为陈述句，语序不变 ②宾语从句若为一般疑问句或特殊疑问句，语序还原为陈述语序 ⑶时态关 ①如果主句是现在的时态，从句时态据实际情况而定 ②如果主句是过去某种时态，从句时态一定变为过去某时态 注意：宾语从句表述的是客观真理，自然现象时，只能用一般现在时 3.人称变化： 4.从句简化 ⑴当主句谓语动词是find, see,watch,hear等时，从句常简化为“宾语+宾补”结构，宾补为省to不定式或v+ing形式
