职称英语考试：地点状语从句及例题解析
主要连接词：where / wherever / everywhere
注意地点状语从句中where与定语从句中关系副词where的区别与联系：
Put the book where it is. (把书放好，即"把书放在该放的地方。)
Put the book in the place where it is.
以上两个句子的意思是一样的，第一个句子是"地点状语从句"，第二个句子是"定语从句"(详见"第四讲")，where作关系副词修饰the place
7) 方式状语从句：
as按时(正如…/ 就象…)
Air is to man as water is to fish.
要点：不要把as 与like 混淆，like是介词，不是连接词， 如不能说：All plants need air like they need water，应为：All plants need air as they need water. (所有的植物需要空气，正如他们需要水一样。)
as if / as though(好象…)可以是真实的，也可以是"虚拟"的，如：
The meat tastes as if (though) it has already gone bad.(这肉吃起来好象变质了。—— 确实坏了)
He speaks English as though (if) he were an Englishman. (他说起英语来好象英国人。—— 他不是英国人，动词用的是were)
