方式狀語從句:
as按時(shí)(正如…/ 就象…)
Air is to man as water is to fish.
要點(diǎn):不要把a(bǔ)s 與like 混淆,like是介詞,不是連接詞, 如不能說:All plants need air like they need water,應(yīng)為:All plants need air as they need water. (所有的植物需要空氣,正如他們需要水一樣。)
as if / as though(好象…)可以是真實(shí)的,也可以是"虛擬"的,如:
The meat tastes as if (though) it has already gone bad.(這肉吃起來好象變質(zhì)了。—— 確實(shí)壞了)
He speaks English as though (if) he were an Englishman. (他說起英語來好象英國人! 他不是英國人,動(dòng)詞用的是were)
8)目的 / 結(jié)果狀語從句
目的狀語從句:
so that / in order that
lest / for fear that (惟恐… / 一以免…) 注意:該句型一般使用"should型"虛擬式(見"第六講")
結(jié)果狀語從句:
so…that / such…that…/ so that / that / so
The professor speaks so fast that we find it difficult to follow him. (這位教授講話很快,我們感到很難理解他講話的意思。要點(diǎn):so + 形容詞或副詞)
He give me such good advice that I finished the task smoothly. (他給了我很好的建議,因此我順利地完成了任務(wù)。要點(diǎn):such + 名詞)
The film was such that everyone was deeply moved. (這部電影如此精彩,每個(gè)觀眾都被深深打動(dòng)了。要點(diǎn):such在這里做代詞,可以理解為:The film is such a good film that…)
順便提一下,"…,only to do…" 雖不屬于從句,但是是一個(gè)重要的表 (意想不到的) 結(jié)果的句型,請記住, 例如:
For nearly three hours we waited for the decision, only to be told to return the next day. (為這個(gè)決定我們幾乎等了三個(gè)小時(shí),可結(jié)果被告知第二天返回。)
從考試角度看,狀語從句的重點(diǎn)是:時(shí)間、原因、條件、讓步和比較
注:如前所述,本講座不是經(jīng)典語法書,有些講法從廣義上說是不完整的,甚至是不確切的,如:"逗號","不能連接兩個(gè)句子"的提法,但這些概念對于理解英語的某些語法現(xiàn)象,特別是解題是實(shí)用的。"相信我,沒錯(cuò)的".
