怎样浅显易懂地解释英语各种从句的逻辑？.docxVIP

（一）问题澄清：何谓从句从题目的正文可以看出来题主问的是名词性从句、形容词性从句（定语从句）、副词性从句（状语从句）三类复杂句从句，但是从句的概念不止如此。英语中的从句概念包括：复合句（compound sentence），常称为并列句，指的是用连词连接多个简单句组成的句子。复杂句（complex sentence），也称为从句、主从复合句，用代词、副词、连词把一个简单句作为另外一个简单句的从属成分的句子。两点说明：上面这两种是专业语法的说法，而一般我们说的复杂句其实指的是比较难比较复杂的句子，可能是简单句、复合句或者复合句。要学好语法，首先就要准确定义这些名词，不然会混，很多争论也是从此而来。复合句和复杂句还可以融合为复合复杂句，也称为并列复杂句，不过理解了复合句和复杂句，就不用单独讨论。虽然题主问的只是上面的第二种，即复杂句（complex sentence），但是无邀自答，把这两种一起讲了，因为这两种从句的根本规律是一体的。（二）总起：从句的一般结构从上面的复合句和复杂句的定义就可以看出来，从句都是两个句子连接起来，代词、副词、连词，都笼统地称为引导词，所以从句的一般结构是：简单句1 + 引导词 + 简单句2关键点在引导词上，分述如下：复合句的引导词：连词复杂句的引导词：代词、副词、连词根据引导词能够连接的句子的完整性（即完整句子与不完整句句子），引导词可以分为两类：代词 + 不完整句子（即SVtO缺少S或者缺少O）副词/连词 + 完整句子（即SVO俱全或者SVi不需要O）（三）复合句复合句 = 简单句1 + 并列连词 + 简单句2而并列连词又极其简单，即fanboys + and yet + and so，fanboys即下列连词的首字母缩写：for: Id better take an umbrella, for it is going to rain.and: He is so handsome and the princess is willing to marry him.nor: The city is not beautiful, nor is it clean.but: I like action movies but she doesn’t like them.or: Take the chance, or you will regret.yet: She walked slowly into the hall and at once noticed that all the room doors were open, yet following her regular practice she had shut them before going out.and yet: She walked slowly into the hall and at once noticed that all the room doors were open, and yet following her regular practice she had shut them before going out.so: It is hard for energetic, quick-minded people to waste time, so they are often tempted to finish a job before setting out to keep an appointment.and so: It is hard for energetic, quick-minded people to waste time, and so they are often tempted to finish a job before setting out to keep an appointment.三点说明：and yet和and so是可以合并的两个连词，其他连词只能用一个（比如and or就不对，and but也不对，当然and/or另当别论。and therefore、and thus等并不是连词合用，因为therefore/thus是副词，所以在and therefore + 简单句2中，therefore只是副词做状语。常见伪连词：thereforehowevermoreover/furthermorenonetheless/neverthelessnotwithstandingthen错误用法句子1, however, 句子2.正确用
