2013中考英語備考:多變的“as”(必背重點)

字號:


    as詞性多,詞義廣,用法靈活,現(xiàn)將其用法歸納如下:
    I. as作副詞, 表示程度, 意為“同樣地”。“as…as…”,表示“和/與……一樣”,是同級比較,其中第一個as是副詞;否定句中常用“not so…as…”,表示“和/與……不一樣”。如:
    Jack is as tall as his father.杰克和他的父親一樣高。
    He doesn’t speak English so/ as fluently as you.
    他的英語說得不如你流利。
    II. as作介詞。
    ①如,像
    They got united as one man.
    他們團結(jié)得像一個人一樣。
    She spoke of me as her dearest friend。
    她談起我猶如我是她最親密的朋友。
    ②充當,作為
    As a writer, he was famous.作為作家,他是很有名的。
    English is spoken as the first language by most people in Australia.
    在澳大利亞,大多數(shù)人把英語作為第一語言。
    ③當某人是(某身份)時
    As a child (=When he was a child),he lived in the countryside.他小時候住在農(nóng)村。
    III. as作連詞, 常用來引導(dǎo)狀語從句
    ①引導(dǎo)時間狀語從句, 表示“當……的時候”;“隨著……”。如:
    He shouted loud as he ran along.
    他一邊往前跑,一邊高聲地呼喊。
    We get wiser as we get older.
    隨著年齡的增長,我們變得更聰明。
    ②引導(dǎo)原因狀語從句,表示“因為,由于”。如:
    As it was getting very late, we soon turned back.
    因為很晚了,我們很快就回來了。
    I must stop writing now, as I have rather a lot of work to do.
    我必須停筆了,因為我還有許多工作要做。
    ③引導(dǎo)比較狀語從句,表示“像……一樣地”。如:
    They always work as hard as we do.
    他們工作總是像我們一樣努力。
    (句中第二個as是連詞,引導(dǎo)比較狀語從句,也屬于同級比較)
    IV. as作關(guān)系代詞, 引導(dǎo)定語從句,表示“正如……”。如:
    He was a foreigner, as I knew from his accent.
    他是個外國人,這一點我是從他的口音中聽出來的。
    [相關(guān)鏈接] 含as的固定詞組
    as soon as 一……就……
    as... as possible = as... as one can 盡可能地……
    as/ so long as 只要
    as if/ though 好像,仿佛
    as to 關(guān)于,至于
    as much/ many as 多達……,達……之多
    so/ as far as I know 就我所知,在句中作插入語
    as a result, as a result of 結(jié)果;由于……的結(jié)果
    as well 也,還
    山東 張新峰
