1、高三英語總復(fù)習(xí)語法系列訓(xùn)練,讓步狀語從句專講,寶安高級中學(xué)高三英語備課組,讓步狀語從句通常用 though, although, no matter, even if, if, even though, however, whatever等引起。 讓步狀語從句可以前置，也可以后置；前置時(shí)強(qiáng)調(diào)主句內(nèi)容，后置時(shí)強(qiáng)調(diào)從句內(nèi)容。有時(shí)也可以采取中位（插入句中）。,1although 和though 引導(dǎo)的讓步狀語從句：,兩個(gè)詞同義，一般情況下可以互換使用，如： He didnt light the fire though / although it was cold. although 比though

2、較正式，語氣較重，常用于強(qiáng)調(diào)讓步概念，如： He insisted on doing it although I warned him not to. though可以和even 連用，但although 不可以，如： Although (Even though) the traffic held us up, we got to the airport on time., 當(dāng)讓步狀語從句是指一種假設(shè)的情況，不指事實(shí)時(shí)，通常用though，而不用although，如： He will never do such a thing though he (should) be forced to.

3、Though all the world were against me, I shall still hold to my opinion. though可以在非正式文體中用作連接性狀語，而although 則不行。（though 可以放在句中或句末，通常用逗號隔開），如： He said he would come; he didnt, though. though引導(dǎo)的從句可用倒裝語序（即把從句中的表語或狀語等放在though之前），而although 不能這樣用，如： Young though she is, yet she is fit for the job. (= Young a

4、s she is, ), 有時(shí)可用副詞yet, still, nevertheless (但不能用連詞but) 來配合連接詞though或although，以加強(qiáng)語氣，如： Though he is over seventy, yet / still / nevertheless he can ride the bike. though和although后面的主語和謂語動(dòng)詞be 可以省略，如果這個(gè)主語和主句中的主語指同一個(gè)人或物時(shí)，如： Though (it was) cold, it was a fine winter morning. Though (he was) severely wo

5、unded, yet he refused to leave the battle field. Though (they were) very tired, they continued to march on.,2even if, even though和 if 引導(dǎo)的讓步狀語從句： even if 與 even though同義，常用于強(qiáng)調(diào)讓步概念，如： Ill do it, even if it takes me all the afternoon. He was there even if we didnt see him. Even if you fail, you can try

6、 again. Ill help you, even if I dont sleep for a night. 注：if 有時(shí)也可以用于讓步含義，但要注意條件if 與讓步if 的區(qū)別，試比較： If he is poor, how can he buy the house? (條件) If he is poor, he is at least honest. (讓步) (= even if) If he is inexperienced, he wont be able to accomplish it. (條件) If he is inexperienced, he is at any ra

7、te eager to learn. (讓步) (= even if) If John had been there, I would have seen him. (條件) If John was there, I didnt see him. (讓步) (= even if),3由as, that, though引導(dǎo)的特殊讓步狀語從句結(jié)構(gòu)： 在正式文體或文學(xué)作品中，為了強(qiáng)調(diào)讓步的含義，可用as引導(dǎo)讓步從句。但as一般不置于句首，而將從句中的表語或狀語置于句首。（though, that與as一樣，也可以用于這種結(jié)構(gòu)），如下面幾種情況：, 表語的倒裝： Tired as he was, he

8、 still went on with his work. Old as I am, I can still fight. Clever as you may be, you cannot do that. Tall as / though he was, he couldnt reach the top shelf. Difficult though the task was, they managed to accomplish it in time., 狀語的倒裝：（這時(shí)不可在狀語之前加very, much等修飾語） Much as I admire him as a writer, I

Hate him as we may, we must admit

10、 his greatness. Search as they would, they could find nothing in the room. Try as you may, you will never succeed.,注意事項(xiàng)：, 如果是單數(shù)名詞或形容詞最高級作表語，不再用冠詞，如： Teacher as Michael is, he is not capable of teaching all subjects. Child as / that he was, he knew what was the right thing to do. Youngest as he is in

11、 our class, he speaks English the best. Child as he is, he knows much. as從句可以置于主句前、主句后或句中，當(dāng)as從句置于句首時(shí)，主句前可加yet ，如： Mary, brave as she is, is afraid of snakes. He was unable to make much progress, hard as he tried. Rich as he is, (yet) I dont envy him., 當(dāng)作表語的形容詞提前時(shí)，如果從句的主語是人稱代詞，那么它只能放在動(dòng)詞之前；如果從句的主語是名詞，

12、則可用倒裝語序，也可用陳述語序，如： Tired as were the workers, they did not stop. Clever though / as you may be, you cant do that. as 從句與主句在時(shí)態(tài)上可以不一致，如： Child as he is, he was brave. 注意區(qū)別as 引導(dǎo)的原因從句與讓步從句，試比較： As he is a lawyer, he explains the reason clearly. (原因從句) Lawyer as he is, he cant explain the reason very cle

(可能知道，也可能不知道。) He will not reveal the secret though he knows it. (雖然知道，卻不說出來。),5while引導(dǎo)的讓步狀語從句： while (= although),它引導(dǎo)的讓步狀語

14、從句只能前置，位于句首，如： While you may be right, I cant altogether agree. While I admit that the problems are difficult, I dont agree that they cannot be solved.,注意比較下列各句： While I admit his good points, I can see his shortcomings. (讓步) While I understand what you say, I cant agree with you. (讓步) While I was r

Whatever others may say, you are certainly right. W

18、hichever (= no matter which) you choose, we have no objection.,8由連接形容詞whatever 或whichever 引導(dǎo)的讓步狀語從句，如： Whatever (= no matter what) difficulties may arise, we must and can overcome them one by one.
