英語(yǔ)是一種西日耳曼語(yǔ)支,最早被中世紀(jì)的英國(guó)使用,并因其廣闊的殖民地而成為世界使用面積最廣的語(yǔ)言。下面是小編為大家收集的as用法,歡迎閱讀,希望大家能夠喜歡。
1. as...as的用法
as...as意為"和……一樣",表示同級(jí)的比較。使用時(shí)要注意第一個(gè)as為副詞,第二個(gè)as為連詞。其基本結(jié)構(gòu)為:as+ adj./ adv. +as。例如:
(1)This film is as interesting as that one.這部電影和那部電影一樣有趣。
(2)Your pen writes as smoothly as mine.你的鋼筆書(shū)寫(xiě)起來(lái)和我的一樣流暢。
其否定式為not as/so +adj./ adv. +as。例如:
This dictionary is not as/so useful as you think.這本字典不如你想象的那樣有用。
若有修飾成分,如twice, three times, half, a quarter等,則須置于第一個(gè)as之前。例如:
Your bag is twice as expensive as mine.你的袋子比我的貴一倍。
幾個(gè)關(guān)于as...as的常見(jiàn)句型:
(1)as...as possible
Please answer my question as soon as possible.請(qǐng)盡快回答我的問(wèn)題。
(2)as...as usual/before
