2、先行词。注意:where引导状语从句时,where是从属连词,where前面没有表示地点的先行词。句型剖析语境领悟(1)She is going to live in Beijing,where she has some close friends.她打算住在北京,在那里她有一些好朋友。(定语从句)(2)The bookshop where I bought this book is not far from here.我买这本书的那家书店离这儿不远。(定语从句)(3)Where there is water,there is life.有水的地方就有生命。(状语从句)句型剖析学以致 用句型转

5、本句that引导宾语从句,做concluded的宾语。在宾语从句中,动词-ing形式短语boiling the sweet wormwood做主语,表示“煮青蒿”这件事情。句型剖析动词-ing形式或动词-ing形式短语可以位于句首直接做主语。谓语动词用第三人称单数形式。有时,也可以用it做形式主语,把动词-ing形式(真实主语)置于句尾。但这种场合不多,多见于某些形容词及名词之后。常见的能用于这种结构的形容词有:good,enjoyable,interesting,foolish,difficult,useless,worthwhile等,构成It is/was+adj.+动词-ing形式。句

7、she said,“The honour is not just mine.”(Page 3)当她听到自己被授予诺贝尔奖时,她说:“这不仅仅是我的荣誉”。句型剖析句法分析在本句中,“介词upon+动词-ing形式”构成介词短语,用作时间状语。有时也可以换成“upon ones doing”的形式。另外,介词upon还可换为on,表示“一件事紧接着另一件事而发生”。这种用法常见于正式的文体,依据语境,可译作“在的时候;当时;一就”。相当于连词as soon as或when引导的时间状语从句。句型剖析语境领悟(1)Upon graduating,he joined a small law firm
