1、三、难句透视1.Many people think it is the most beautiful city in Canada ,as it is surrounded by mountains on the north and east and the Pacific Ocean on the west.很多人认为温哥华是加拿大最漂亮的城市，因为它北部、东部由高山环绕，西部临太平洋。【剖析】这是一个主从复合句，在主句中 think 后跟了一个宾语从句， as 引导了一个原因状语从句。其中 be surrounded by 是被所包围之意。【归纳】as, because ,for 与 si
2、ncebecause 语气最强，所表示的是 why 的直接理由或原因；若说话人认为事因已比较清楚，主要是为了表明语言或思维上的因果关系就用 as 或 since ;for 是并列连词，两个分句之间有时并不存在着困果关系，此时 for 分句只是说话人为了对前面的分句所表示的事实进行推论而主观设立的一种论据，for 不放于句首。Because I was ill for one year, I lost my job.因为我病了一年，所以我失业了。Since everyone is here ,lets begin our class.既然大家都来了，咱们就开始上课吧。活学巧用1.1）单项填空(1

5、as 引导的是时间状语从句，在该从句中 the train 是主语， rushed 是谓语，有四个状语，分别是 through the night, across the top of Lake Superior, through the great forests 和 southward towards Toronto.【归纳】（1）注意介词 across 与 through 的用法区别：across “横过；穿过 ”，着重指从一条线或一物体表面的一边到另一边；含义与 on 有关：across the street 横过马路through 穿过，从中通过，着重指从空间的一头纵穿到另一头；含义
