so as to用法（so as）

關(guān)于so as to用法，so as這個問題很多朋友還不知道，今天小六來為大家解答以上的問題，現(xiàn)在讓我們一起來看看吧！

1、as ...as 表示“和...一樣”之意；用于同級比較時,既可用于肯定中也可用于否定句中,如：Mike is AS tall AS I.麥克和我一般高.Mike is not AS tall As I.麥克沒有我高.so … as 只能用于否定句中,也就是說,通常是以 not so...as 出現(xiàn)的；如：The Atlantic Ocean is NOT AS big AS the Pacific Ocean.大西洋沒有太平洋大.在否定句中既可以用 not as ...as...也可以用 not so...as,而在肯定句中只能用 as...as; 關(guān)于as...as的常見句型：(1)as...as possible Please answer my question as soon as possible.請盡快回答我的問題.(2)as...as usual/before She looks as pretty as before.她看起來和以前一樣漂亮.(3)as long as...(引導(dǎo)條件狀語從句) It took us as long as three years to carry out the plan.我們花了長達三年的時間才完成這項計劃.(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。
