1.as far as=so far as
就……而言,至于
【例句】As far as I am concerned, I'm not against your plan.
就我而言,我并不反對你的計(jì)劃.
遠(yuǎn)到
【例句】He walked as far as the railway station yesterday evening. 昨天傍晚,他一直散步到火車站.
【總結(jié)】表示"直到……為止"之意時(shí),as far as既可用于肯定句,也可用于否定句;在表示"直到……程度"之意的借喻說法中,as far as和so far as都可使用,但前者不及后者用得普遍.在表示"就……而論"之意時(shí),as far as和so far as可互換使用.在表示"只要"、"盡……所能"之意時(shí),應(yīng)用as far as,不用so far as.
2.as if 似乎、好像
【例句】She treats himas if he were a stranger.
她待他如陌生人.
【總結(jié)】(一)as if 從句的作用.在look, seem 等系動詞后引導(dǎo)表語從句.如:She looks as if she were ten years younger. 她看起來好像年輕了十歲.引導(dǎo)方式狀語從句.如:She loves the boy as if she were his mother. 她愛這男孩,就好像她是他的母親一樣.
(二)as if 還可用于省略句中 如果as if 引導(dǎo)的從句是"主語+系動詞"結(jié)構(gòu),可省略主語和系動詞,這樣as if 后就只剩下名詞、不定式、形容詞(短語)、介詞短語或分詞.如:He acts as if (he was) a fool. 他做事像個(gè)傻子.
(三)as if 從句的語氣及時(shí)態(tài) as if 從句用陳述語氣的情況.當(dāng)說話者認(rèn)為句子所述的是真實(shí)的或極有可能發(fā)生或存在的事實(shí)時(shí).如:It sounds as if it is raining. 聽起來像是在下雨.He talks as if he is drunk. 從他談話的樣子來看他是醉了.as if從句用虛擬語氣的情況.當(dāng)說話人認(rèn)為句子所述的是不真實(shí)的或極少有可能發(fā)生或存在的情況時(shí).從句虛擬語氣動詞時(shí)態(tài)的形式如下:
a.如果從句表示與現(xiàn)在事實(shí)相反,謂語動詞用一般過去時(shí).如:ou look as if you didn't care. 你看上去好像并不在乎.
b.從句表示與過去事實(shí)相反,謂語動詞用"had+過去分詞".如:He talks about Rome as if he had been there before. 他說起羅馬來好像他以前去過羅馬似的.
c.從句表示與將來事實(shí)相反,謂語動詞用"would/could/might+動詞原形".如:He opened his mouth as if he would say something. 他張開嘴好像要說什么.
3.as long as=so long as
只要
【例句】As long as you don't betray me, I'll do whatever you ask me to (do).
只要你不出賣我,要我做什么我都愿意.
as long as: 和……一樣長
【例句】This line is four times as long as that one.
這條線是那條線的四倍長.
【總結(jié)】?當(dāng)用于同級比較時(shí),as.....as 既可用于肯定中也可用于否定句中,
而so....as 只能用于否定句中.
His pencil is as long as mine.
His pencil isn't so/as long as mine.
當(dāng)表示只要時(shí),兩者沒有什么區(qū)別,可以替換.
e.g.Our profits will be good as/so long as the dollar remains strong.
【詞語辨析】as long as ,as far as
as long as有"只要"的意思
As long as you keep working, you will get what you want.
as far as的意思比較抽象,可以表示距離上的"遠(yuǎn)到,直到"也有"據(jù)我所知"的意思,翻譯起來可根據(jù)上下文語境靈活處理.
As far as I can see, it is a perfect plan.
在我看來,這是個(gè)完美的計(jì)劃.
4.as well as
①和……一樣
【例句】She as well as you is an English teacher.
她像你一樣也是英文教師.
②與……一樣好
【例句】He speaks Spanish as well as English. 他說西班牙語像說英語一樣好.
【總結(jié)】A as well as B的結(jié)構(gòu)里,語意的重點(diǎn)在A,不在B.
