我們平時(shí)在課本中經(jīng)常碰到as long as這樣的句子，那么有些學(xué)生就要問了：這個(gè)as long as 到底是什么意思呀，它怎么用?下面，答案網(wǎng)小編就來給大家談?wù)?strong>as long as的用法有哪些吧！
一、as long as解釋：
1.長(zhǎng)達(dá)；達(dá)…之久
2.當(dāng)…時(shí)候
3.既然，由于，因?yàn)?/p>
4.如果，只要，在…情形下
二、as long as 是介詞短語(yǔ)，一般接句子
1.As long as arranging the time reasonably,we are sure to benfit more from recreational activities.(08年6月CET-4里的.)
其中的arranging ，并不是說該詞后加動(dòng)詞ing形式，arranging 是句子arranging the time reasonably中的部分，是獨(dú)立主格形式，它不能看作是as long as后加動(dòng)名詞。
2.as long as it isn't boring就是一個(gè)例子，而As long as do not rain!實(shí)際上是省略句，省略了it ，完整的用法是As long as it do not rain!至于什么時(shí)候省略，隨著英語(yǔ)學(xué)習(xí)的加深，自然能夠形成這種語(yǔ)感。
三、.as long as其實(shí)有三個(gè)意思：
1) 只要 = so long as = while
如：You'll succeed as long as you work hard.
只要你好好學(xué)習(xí),你就會(huì)成功的.
2）(長(zhǎng)度上)和...一樣長(zhǎng) / 長(zhǎng)至...(程度)/ 長(zhǎng)達(dá)...
如：The room is as long as 10 meters.
這個(gè)房間長(zhǎng)達(dá)10米.
3）(時(shí)間上)和...一樣久 / 久至.../ 長(zhǎng)達(dá)...
如：I've lived here as long as 20 years.
我在此處居住長(zhǎng)達(dá)20年之久.
四、"as long as" =有三個(gè)用法:
1.During the time that (在這段時(shí)間):I'll stay as long as you need me.
2.Since (既然) :As long as you've offered,I accept.
3.On the condition that (條件是):I will cooperate as long as I am notified on time.
