专升本英语语法学习中,学习让步状语从句的关键是关联词的选用,其次要注意的是由as引导的让步状语从句要用倒装语序。下面湖北专升本网就为大家整理了一些让步状语从句语法,希望对大家有所帮助。
1.whether...or...表示“不论是否……”,“不管是……还是……”之意。由这一个复合连词引导的让步状语从句 旨在说明正反两个方面的可能性都不会影响主句的意向或结果。
例如:You\'ll have to attend the ceremony whether you\'re free or busy. 不管你忙不忙,都要参加这个典礼。
2.though, although。 当有though, although时,后面的从句不能有but,但是 though 和yet可连用
例如:Although it\'s raining, they are still working in the field.虽然在下雨,但他们仍在地里干活。
注意,although引导的让步状语从句位于主句之前的情况较多,though引导的让步状语从句可位于主句之前或主句之后。例如:She passed the examination though she had not studied very hard. 她虽然不用功学习,考试却及格了。
3.as, though 引导的倒装句。as 引导的让步从句必须表语或状语提前(形容词、副词、分词、实义动词提前),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),though还可以用作副词,放在句末。
例如:Child as /though he was, he knew what was the right thing to do.= Though he was a small child, he knew what was the right thing to do.
注意:(1)句首名词不能带任何冠词。(2)句首是实义动词,其他助动词放在主语后。如果实义动词有宾语和状语,随实义动词一起放在主语之前。
4.ever if, even though. 即使。例如:We\'ll make a trip even though the weather is bad.
5."no matter +疑问词" 或"疑问词+后缀ever"。
no matter与what(who,which,when,etc。)与whatever(whoever,whichever,whenever,etc。)的区别: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,表语从句和同谓语从句)时则只能用whatever(whoever,whichever,whenever,etc)。
例如:No matter what happened, he would not mind.或者是Whatever happened, he would not mind.
6.常见的让步状语词组替换
no matter what = whatever;no matter who = whoever;no matter when = whenever
no matter where = wherever;no matter which = whichever;no matter how = however
注意:no matter 不能引导主语从句和宾语从句。
让步状语从句表示:虽然,尽管,即使等概念,由although(尽管), though(尽管), however(无论怎样), whatever(无论什么), whoever(无论谁), whomever(无论谁), whichever(无论哪个), whenever(无论何时), wherever(无论哪里), whether(是否), no matter (who, what, where, when, etc) (无论……), even if(即使), even though(即使)等词引导。
