2019-2020年高中英语 Module 6The Worlds culture heritage教案（5） 外研版选修7GoalTo learn the adverbial clauses of place, condition and concession ProceduresStep 1: adverbial clauses of place, condition and concession状语从句在句中作状语，修饰主句中的动词、形容词或副词等。状语从句放在主句之前时，常用逗号分开；放在主句之后，一般不用逗号。状语从句按其意义和作用可分为时间、原因、条件、让步、地点、目的、结果、方式、比较等九种。本单元主要熟悉掌握地点、条件和让步状语从句。1.地点状语从句 1）地点状语从句常由where和wherever引导，通常可置于主句之前或之后。I found the books where I left them. Make a mark where you have any questions. We should go where(ver) we are most needed. Where there is a will, there is a way. Where there is water, there is life. 2）where引导的状语从句和where引导的定语从句常可转换，判断它属于哪类从句的关键是看where前面有没有被修饰的、表示地点的先行词。试比较： Stand where you are! （状语从句） Stand at the place where you are! （定语从句） Bamboo grows best where its wet and rainy. （状语从句） Bamboo grows best in places where its wet and rainy. （定语从句）2.条件状语从句 条件句可分为真实条件句和非真实条件句，非真实条件句在虚拟语气中有详细表述，这里只讨论真实条件句。引导条件句常用的有if, unless, as(so) long as, in case等，when, once, suppose (that) 或supposing (that)，on condition that 也可引导表示条件的从句。条件状语从句和时间状语从句一样，表示将来要用一般现在时。例如： The bell is rung if there is a fire. We wont let you in unless you show your pass. You may use my bike as/so long as you return it before Friday. In case anything important happens, please call me up. Turn off the switch when anything goes wrong. Once you taste the noodles, youll never forget their delicious flavour. Suppose/Supposing (that) you fail again this time, what will you do? He agreed to lend him the money on condition that he paid back three times more money in three months time. 3.让步状语从句 1）通常由though, although, even/though引导，主句中不能用but，但可用yet。如： He didnt light the fire though/although it was cold. Although/though he is quite old, (yet) he still tries to learn more. Ill try to finish the work myself even if/though it takes me days. 2）whatever, whoever, whichever, whenever, wherever, however 引导状语从句时，分别相当于no matter what/who/which/when/where/how引导的从句，意为“无论”。例如： Whatever/No matter what he said, no one believed him. Whoever/No matter who breaks the law, he will be punished. Whichever/No matter which job you take, you should try to do well in it. Whenever/No matter when I need his help, he es immediately. Wherever/No matter where you go, never forget your motherland. However/No matter how busy he was, he would watch TV sports news every night. 注意whatever, whoever, whichever又可引导名词性从句，注意区别。可参阅本章第一节。 3）as引导让步状语从句要倒装，其结构通常是“n./adj./adv. + as + 主语+谓语(+其它成分)，主句”，可转换成though/although从句。 Child as he is, he knows a lot. （注意：名词前不用冠词） =Although/Though he is a child, he knows a lot. Difficult as the task was, they managed to finish it in time. =Although/Though the task was difficult, they managed to finish it in time. Much as I like it, I will not buy it. =Although/Though I like it much, I will not buy it. 偶尔也可见用动词提前的让步状语从句。例如： Try as he may, he can hardly do better than she. =Although/Though he may try, he can hardly do better than she. 4）whetheror也可引导让步状语从句，相当于“no matter whetheror”。 Whether you e in winter or in summer, you will find it a nice place. =No matter whether you e in winter or in summer, you will find it a nice place.Step 2: 链接1. _ he has limited technical knowledge, the old worker has a lot of experience.
