as用法小結(jié)(2)

　　(4)as far as

　　He walked as far as the railway station yesterday evening.昨天傍晚，他一直散步到火車站。

　　(5)as well as

　　She cooks as well as her mother does.她燒菜燒得跟她母親一樣好。

　　【知識(shí)拓展2】：一些帶有as...as結(jié)構(gòu)的常見(jiàn)短語(yǔ)歸納：

　　as busy as a bee像蜜蜂一樣忙碌 　　 as easy as ABC像ABC一樣容易

　　as deep as a well像井一樣深 　　 as light as a feather像羽毛一樣輕

　　as soft as butter像黃油一樣軟 　　 as rich as a Jew像猶太人一樣富裕

　　as strong as a horse健壯如牛 as poor as a church mouse一貧如洗

　　as cool as a cucumber十分冷靜;鎮(zhèn)定自若

　　二、as作為關(guān)系代詞，可以引導(dǎo)定語(yǔ)從句，既可以單獨(dú)使用，也可以與其他詞連用，其用法要比that和which更為復(fù)雜，而且as在定語(yǔ)從句中可以充當(dāng)主語(yǔ)、賓語(yǔ)、介詞賓語(yǔ)、表語(yǔ)，可以指人也可指物。要注意引導(dǎo)定語(yǔ)從句時(shí)。

　　1、引導(dǎo)限制性定從句。

　?、儆糜趖he same...as結(jié)構(gòu)中。

　　This is the same book as I read last week.這本書和我上周讀的那本是一樣的。

　　He isn’t the same person as he used to be.

　?、谟糜趕uch...as結(jié)構(gòu)中。

　　I have never heard such story as he is telling.

　　I don’t like such books as he recommends. 我不喜歡他推薦的那些書。

　?、塾糜?quot;as/so +adj. + a/an + n. (單數(shù)) + as "結(jié)構(gòu)中

　　I am not so strong a man as I was.我已經(jīng)沒(méi)有從前那么強(qiáng)壯了。

　　2、引導(dǎo)非限制性定從句，修飾整個(gè)主句或主句的一部分，可在句首、句中、句末。當(dāng) as 在從句中做主語(yǔ)時(shí)，從句的謂語(yǔ)動(dòng)詞常是被動(dòng)語(yǔ)態(tài)或系表結(jié)構(gòu)。在從句中做賓語(yǔ)時(shí)，從句的謂語(yǔ)動(dòng)詞常是情態(tài)動(dòng)詞 + 動(dòng)詞原形。

　　As is often the case, we have overfull filled the production plan.

　　This machine, as might be expected, has stopped operating.

　　He came very early this morning, as (was) usual.

　　She is late, as is often the case.她遲到了，這是經(jīng)常的事。(先行詞是整個(gè)主句)

　　To shut your eyes to facts, as many of you do, is foolish.

　　對(duì)事實(shí)視而不見(jiàn)--你們好多人都是如此的愚蠢。(先行詞是不定式短語(yǔ))

　　此外還有: as has been said before/ as may be imagined / as is well known/ as we all can see/ as often happens/ as has already been pointed out等等。

　　三、as作為介詞的用法：

　　1. 表示“好像”。如:He dressed as a policeman.

　　2. 表示“作為”，“當(dāng)作”。如：I found a job as a guide.

　　3. 表示某人是什么某身份時(shí)。如：As a child , she was sent to abroad.

　　He came to China as a tourist five years ago.他五年前以游客的身份來(lái)過(guò)中國(guó)。

　　4. as引導(dǎo)的介詞短語(yǔ)大多用作狀語(yǔ),as譯為"作為";少數(shù)情況可引起賓語(yǔ)補(bǔ)足語(yǔ)。如:

　　As a Party member, I'll take the lead in everything. (狀語(yǔ))

　　She works as a model. (狀語(yǔ))

　　She has me as one of her best friends.(引起賓語(yǔ)補(bǔ)足語(yǔ))

　　四、as作為副詞的用法：

　　1、意思為“相同地”，“ 同樣地”=(to the same degree or amount; equally)

　　例如：They don’t have as many airplanes.他們沒(méi)有同樣多的飛機(jī)。

　　This dress is twice as expensive as that one.

　　2、意思為“像，如”等。如：As before, he remained unmoved.

　　總之，通過(guò)以上的分析，我們對(duì)as的詞性和用法有了比較全面的理解和把握，才能在實(shí)際的運(yùn)用中做到心中有數(shù)，應(yīng)付裕如。
