7) 方式狀語從句:
as按時(正如…/ 就象…) Air is to man as water is to fish.
要點:不要把as 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! 確實壞了)
He speaks English as though (if) he were a醫(yī)學(xué)全在線m.52667788.cnn Englishman. (他說起英語來好象英國人! 他不是英國人,動詞用的是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: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:such + 名詞)
The film was such that everyone was deeply moved. (這部電影如此精彩,每個觀眾都被深深打動了。要點: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. (為這個決定我們幾乎等了三個小時,可結(jié)果被告知第二天返回。)
從考試角度看,狀語從句的重點是:時間、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,特別是解題是實用的。"相信我,沒錯的".
(1) 原級比較:as +形容詞或副詞原級+ as, 否定式:not so (或as) +形容詞或副詞原級+ as 注意問題:as…as 之間的形容詞或副詞是否采用了原級;as…as 之間該醫(yī)學(xué)全在線m.52667788.cn用形容詞還是副詞;用as much as 還是用as many as 表示倍數(shù)時用下面結(jié)構(gòu), 如3倍:three times as …as… 例如:
The size of the island is about ______ that of this one.
A.three times as much as B.as three times much as C.as three times greater than D.three times as big as
解題思路:B、C違反了上述句型規(guī)定,A、D的區(qū)別是size(大小 / 尺寸)是與much搭配還是與big搭配,D是對的。
(2) 比較級:more …than… 注意:
1) 比較形式是否正確,如是否有類似"more better"這樣重復(fù)比較的錯誤;
2)兩者之間是比較級,三者以上是最高級,看看是"兩者"還是"三者或三者以上;
3)只有同類的人或物才能比較(可比性);比較不能包括"自己", 常用other表示排除。
例如不能說: He is taller than any students in this class.
