职称英语语法:第九讲c

分类: 职称英语 

6) 地点状语从句:

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)

8)目的 / 结果状语从句

目的状语从句:

so that / in order that

lest / for fear that (惟恐… / 一以免…) 注意:该句型一般使用"should型"虚拟式(见"第六讲")

结果状语从句:

so…that / such…that…/ so that / that / so

The professor speaks so fast that we find it difficult to follow him. (这位教授讲话很快,我们感到很难理解他讲话的意思。要点:so + 形容词或副词)

He give me such good advice that I finished the task smoothly. (他给了我很好的建议,因此我顺利地完成了任务。要点:such + 名词)

The film was such that everyone was deeply moved. (这部电影如此精彩,每个观众都被深深打动了。要点:such在这里做代词,可以理解为:The film is such a good film that…)

顺便提一下,"…,only to do…" 虽不属于从句,但是是一个重要的表 (意想不到的) 结果的句型,请记住, 例如:

For nearly three hours we waited for the decision, only to be told to return the next day. (为这个决定我们几乎等了三个小时,可结果被告知第二天返回。)

从考试角度看,状语从句的重点是:时间、原因、条件、让步和比较

注:如前所述,本讲座不是经典语法书,有些讲法从广义上说是不完整的,甚至是不确切的,如:"逗号","不能连接两个句子"的提法,但这些概念对于理解英语的某些语法现象,特别是解题是实用的。"相信我,没错的".
