as long as的用法有哪些

更新時(shí)間:2018/9/25 23:56:00  手機(jī)版

  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(wèn)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(lái)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(shuō)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.
