2、ssage in case you have any difficulty.As long as we dont lose heart, well find a way to overcome any difficulty.You cant learn English well unless you work hard. 除非你努力学习，否则你学不好英语。 You can use my bike on condition that you return it by Friday. 你可以使用我的自行车，条件是你星期五以前还。 3. 让步状语从句让步状语从句常用although/though（虽
3、然），even though/even if（尽管），as（尽管），whatever/whenever/however（无论什么/何时/如何），no matter what/when/how（无论什么/何时/如何）等引导。下面对这些连词引导的让步状语从句作一说明。（1） though, although表示“虽然，纵然”之意。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, still或nevertheless连用，但不能与but连用。例如：Although/Though he was worn out,
4、(still) he kept on working. 虽然他已经精疲力竭了，但仍然继续工作。Although/Though he is very old, (yet) he is quite strong. 他虽然年纪大了，身体还很健壮。（2）as, though表示“虽然但是”，“纵使”之意。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，但although不可以这样用。例如：Object as you may, Ill go. (=Though/Although you may object, Ill go.) 纵
5、使你反对，我也要去。Hard as/ though he works, he makes little progress. (=Though he works hard, he makes little progress.)尽管他学习很努力，但几乎没取得什么进步。Child as/though he was, he knew what was the right thing to do.（=Though he was a child, he knew what was the right thing to do.）虽然他是一个孩子，但他知道该做什么。 (3). though还可以用作副词，放在
6、句末。如：It was hard work; I enjoyed it, though=It was hard work, but I enjoyed it.那工作很苦，但是我喜欢干。（4）even if, even though 表示“即使”，“纵使”之意。这两个复合连词的意思基本相同。它们常可互换使用，但意义有细微差别。even if引导的让步从句含有强烈的假定性，而even though引导让步状语从句时，是以从句的内容为先决条件的，也就是说，说话人肯定了从句的事实。例如：Well make a trip even if/though the weather is bad. 即使天气不好
7、，我们也要作一次旅行。Even if he is poor, she loves him. (=He may be poor, yet she loves him.)即使他很穷，但她还是爱他。Even though he is poor, she loves him. (=He is poor, yet she loves him. )尽管他很穷，但她还是爱她。（5）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 wh
8、ether youre free or busy. 不管你忙不忙，都要参加这个典礼。Whether you believe it or not, its true.无论你是否相信，这都是真的。（6）“no matter+疑问词”或“疑问词-ever”的含义为“都；不管都”，它们引导的让步状语从句可以互换。例如：No matter what happened, he would not mind. (=Whatever happened, he would not mind.)无论发生了什么，他都不会介意的。No matter who you are, you must keep the law
9、.(=Whoever you are, you must keep the law.不管你是谁，你都要遵纪守法。但“no matter+疑问词”结构只能引导让步状语从句，而“疑问词-ever”还可以引导名词性从句。例如：Whatever(=No matter what)you say, I won t believe you. (Whatever 引导让步状语从句)无论你说什么，我都不会相信你。Ill eat whatever(no matter what)you give me. (whatever引导宾语从句)你给我吃什么，我就吃什么。Whoever comes will be welcome. (Whoever 引导主语从句) 不管谁来都受到欢迎。
