条件状语从句让步状语从句结果状语从句用法 1. 条件状语从句 连接词主要有 if, unless, as/so long as, on condition that 等。if 引导的条件句有真实条件句和非真实条件句两种。非真实条件句已在虚拟语气中阐述。 unless = if not. 例如： Let's go out for a walk unless you are too tired. 如果不太累，我们去散散步。 If you are not too tied, let's go out for a walk. 典型例题 You will be late ___ you leave immediately. A. unless B. until C. if D. or 答案A。句意：除非你立即走，否则你就回迟到的。可转化为 If you dong leave immediately, you will be late。B、D句意不对，or表转折，句子如为 You leave immediately or you will be late. 2. 让步状语从句 （1）though, although引导的让步状语从句，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。 He is very old, but he still works very hard. 虽然他很老了，但仍然努力地工作。 （2）as, though 引导的让步从句表语或状语提前（形容词、副词、分词、实义动词提前）。例如：Child as /though he was, he knew what was the right thing to do. 虽然是个小孩，该做什么不做什么，他全知道。 （3）ever if, even though 即使。例如： We'll make a trip even though the weather is bad. 即使天气不好，我们也要去远足。 （4）whether…or… 不管……都。例如： Whether you believe it or not, it is true. 信不信由你，这确实是真的。 （5）"no matter +疑问词" 或"疑问词+后缀ever" 。例如： No matter what happened, he would not mind. =Whatever happened, he would not mind. 不管发生什么，他不在意。 替换：no matter what = whatever no matter who = whoever no matter when = wheneverno 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。 3.结果状语从句 结果状语从句常由so…that 或 such…that引导。so…that与such…that之间可以转换。例如： The boy is so young that he can't go to school. 这男孩年龄太小，不能上学。 He is such a young boy that he can't go to school 题一： Was it in this palace ________ the last emperor died? A. that B. in which C. in where D. which 题二： It was a year ago ________ I first met him here. A. which B. that C. in which D. when 题三： It is Zhuang Hua ________has seen the film before. A. which B. who C. whom D. whose 题四： It is these poisonous products ______ can cause the symptoms of the flu, such as headache and aching muscles. A. who B. that C. how D. what 题五： —Where did you get to know her? —It was on the farm _____ you worked. A. that B. there C. which D. where 题一： A 详解：这是个强调句型，所以选that。被强调部分是in this palace。 题二： B 详解：这是个强调句型，所以选that。被强调部分是 a year ago。 题三： B 详解：这是个强调句型，被强调部分是主语Zhuang Hua。因为Zhuang Hua指人作主语，所以出了用that之外, 还可以用who。 题四： B 详解：这是一个强调句型。被强调部分是these poisonous products，所以选 that 。 在强调句型中，引导词有that和who。that任何情况下都可以用，who强调指人的主语时才可以用。 题五： D 详解：_____ you worked是定语从句，其先行词为the farm。从句缺少地点状语，所以选where引导定语从句。在这个题中，on the farm是被强调部分，后接一个定语从句修饰the farm，定语从句之后是that引导的强调句型部分。为了避免重复，在回答的时候把强调句“that+＋原句其它部分”都省去。把答句补充完整应为It was on the farm where you worked that I got to know her.
