1、让步状语从句用法分析1. as引导让步状语从句的用法：引导让步状语从句时，as意为“虽然，尽管”，通常从句要倒装，倒装的方法是将从句的表语或状语放在as之前，而用though引导让步状语从句时句字则不必倒装（口语中也可倒装）,但although不能使用倒装用法。eg. Heavily as it was raining out side,they started out very early.Young as he is,he knows a lot=Though he is young / Young though he is,he knows a lot.2. 用though/althou
2、gh,as引导让步状语从句时，句中不能用but表示转折语气。eg. Though she is beautiful, but nobody like her. ()Though she is beautiful, nobody like her.（）She looks beautiful,but nobody like her.（）3. however 用作副词，不可连接句子。eg: Alice is a good studentHowever,she has one shortcomingHe has not arrived. He may,however,come later.The ho
3、tel has no room avaliable. There is room reserved,however.4. no matter 疑问词 与 疑问词ever ：当引导引导让步状语从句时，两者相同，可以互换，但后者可以引导名词性从句，前者则不能。eg. I am ready to do whatever you want me to .（宾语从句）No matter who (whoever) you are, I will still love you.引导让步状语从句的连词让步状语从句是状语从句中用法较为复杂的一种，连词总类较多用法也多，让人不容易记住，并且让步状语从句在句子意义
4、表达上也有许多容易混淆的地方，给学习者们带来不少困惑让步状语从句是状语从句中的一种，一般翻译为“尽管”或“即使”。引导让步状语从句的连词主要有以下这些：though,although,while,as; even if,eventhough; whether.or.; no matter+疑问词，疑问词-ever，regardless of+名词/名词短语/名词从句，despite，in spite of。 though，although：“虽然，纵然”，这两个连词意思大致相同，在一般情况下可以互换使用。在口语中，though较常使用，although比though正式，二者都可与yet，st
5、ill或nevertheless连用，但不能与but连用。eg. I will go to school though its too late now. Although he was exhausted, he(still) kept on working. Although/Though he is very old, (yet) he is quite strong. as（though）：“虽然但是”，“纵使”，as引导的让步状语从句必须以部分倒装的形式出现，被倒装的部分可以是表语、状语或动词原形，though也可用于这样的结构中。eg. Object as/though you m
6、ay, Ill go.(=Though/Although you may object, Ill go.)Fast as you write, you cant finish your paper in only one night.Lover of towns as I am, I realize that I owe a debt to my early country life. whether：“无论，不论，不管”，由这一个复合连词引导的让步状语从句旨在说明正反两方面的可能性都不会影响主句的意向或结果，所以它的语气是比较强烈的。eg. Youll have to attend the
7、ceremony whether youre free or busy.Whether you believe it or not, its true.Whether or not you like her, you have to become her husband. no matter+疑问词=疑问词-ever：“都；不管都”eg. No matter what happened, he would not mind. =Whatever happened, he would not mind. whether.or.：“不论是否”，“不管是还是”eg. Whether you are
8、rich or poor, the end result is the same, death.语法核心：让步状语从句学习必须注意的地方让步状语从句是指某一个句子发生在某一个时态，句子本身就是状语从句，这个状语从句让了一步给主句，一般翻译为“尽管”或“即使”。让步状语从句时从句学习中的一个难点，很多人都不会使用1. 引导让步状语从句的从属连词主要有 although, though, however (=no matter how), even if(即使), whetheror(不论还是)等连词。如：The speech is good, though it could be better.
9、 这次演讲不错，虽然还可以再好一点。He went out even though it was raining. 尽管下雨，他还是出去了。2. as 也可引导让步状语从句，但要将名词、形容词或副词等提到 as 前，若提前的是单数可数名词，要省略 a / an。如：Teacher as he is, he cant know everything. 虽然是老师，他也不可能什么都懂。3. 连词 while 有时也可表示“尽管”、“虽然”，引导让步状语从句。如：While we dont agree we continue to be friends. 尽管我们意见不同，我们还是朋友。4. wha
10、tever, whoever, however, whenever, wherever 等引导让步状语从句。如：Dont lose heart whatever you do. 不管你做什么，都不要灰心。Whoever you are, you cant pass this way. 不管你是谁，你都不能从这里通过。注：表示“虽然”的 though, although 不可与 but 连用，但可与 yet, still .连用让步状语从句中even if 和even though的区别even if 和 even though都可以用于状语从句，两者意思相近，所以经常被替换使用，确实利用近义词
11、可以增加句子的词汇丰富度，但是在英语里往往不存在意思完全一样的词，这两个词也有些许微妙的差别，如果用得不合适了，便会给人生硬的感觉，所以这次小编就来跟大家一起学习一下这两者的异同。1. even if引导的从句是往往是假设性的，相当于汉语的“即使”“纵然”“就算”“哪怕”，有时还可以用于虚拟语气，意思与if接近。eg. Theyll stand by you even if you dont succeed.Even if it rains tomorrow, we wont change our plan.Even if he had the chance, he wouldnt catch
12、 it. (虚拟语气，就算有机会也不会抓住)2. even though引导的从句内容往往是真实的，主要用于引出不利用于主句情况的信息，相当于汉语的“尽管”“虽然”，与 though，although意思接近。eg. He went out even though it was raining.He is the best student even though he has the least time to study.Even though (thought, although)I feet sorry for father, l am secretly pleased that he
13、has the time to play with me.3. 在口语中，even if与even though有时也可不加区别地混用。eg. Even if (even though) he hurted her, she still loves him.We are good friends, even if (even though) we keep some secrets to each other.让步状语从句：whatever, however 等 -ever词解析(1) 它们均可引导让步状语从句，意为 “无论”：Whatever its obscurities, the poe

15、ter，如说：The centre is open to all, no matter what race or creed. 该中心向所有人开放，不论种族和宗教信仰如何。He had decided to publish the manuscript no matter what. 他决定无论如何都要出版那部手稿。No matter what you say, I like to listen. 不管你说什么, 我都喜欢听.(3) 注意however以下两类句型结构： however+主语+谓语：However you travel, itll take you at least three
16、 days. 不管你怎么走，至少要三天。However you come, be sure to come early. 不管你怎么来，一定要早来。 however+形容词或副词+主语+谓语：However much he eats, he never gets fat. 无论他吃多少, 他都不发胖。However cold it is, she always goes swimming. 不管天多冷，她都会去游泳。有时该结构中的主语和谓语可以有所省略：He was of some help, however small. 他总能帮些忙，不管多小的忙。I refuse, however fav
17、orable the condition. 不管条件多好，我都不接受。(4) 有时从句谓语可用情态动词：Ill find him, wherever he is may be. 无论他在哪里，我都要找到他。Keep calm, whatever happens may happen. 无论发生什么事都要保持冷静。(5) whenever有时可引导时间状语从句，wherever 有时可引导地点状语从句：Whenever we see him we speak to him. 每次见到他，我们都和他说话。They teach wherever their pupils are working. 学
18、生在哪里工作，教师们就在哪里上课。让步状语从句：no matter what 与 -ever 的区别解析no matter what（who,which,when,etc.）与 whatever（whoever,whichever,whenever,etc.）都可以应用在让步状语从句中，但是在特殊情况下，只能用whatever。下面，小编就来为大家简单介绍一下。当引导让步状语从句时, 两者相同, 可以互换, 但当引导名词性从句（主语从句,宾语从句,表语从句和同位语从句）时则只能用whatever（whoever,whichever,whenever,etc）.例如：Dont be overaw
19、ed by people in authority, however important they are. 不管当官儿的职权有多大，都不要被他们吓倒。The effect of pushing the button is the same no matter who does it. 不论是什么人去按电钮,其效果都是一样的.下面句子不能用no matter结构 (no matter不能引导名词性从句）: Whoever comes back first is supposed to win the prize. (主语从句)I am ready to do whatever you want
20、 me to .（宾语从句）例证：Whatever you did, I will accept.为让步状语从句.I will accept whatever you did.为宾语从句.用though/although, as 引导让步状语从句时,句中不能用but表示转折语气. ：Though he looks weak, but he is healthy. ：Though he looks weak, he is healthy. 或者说：He looks weak, but he is healthy. 我自己认为让步就是存在一定条件下的说法. 除以上提到的从句连词外,表示让步的介词短
21、语有despite, in spite of, 后接名词.eg. Despite all these facts, we cannot ignore the advantages of learning through internet.however 用作副词,不可连接句子. 但可置于第二句的句首、句末或句中.要特别注意标点的使用.eg: Alice is a good studentHowever, she has one shortcoming He has not arrived.
