所有的主從復(fù)合句，主從句的時(shí)態(tài)都得一致。一致并不意味著時(shí)態(tài)完全一樣，只要從時(shí)間關(guān)系上講得通即可。用as soon as引導(dǎo)時(shí)間從句時(shí)要注意“主將從現(xiàn)”即從句用一般現(xiàn)在時(shí)表將來。

as long as是介詞短語，一般接句子，如：

1.As long as arranging the time reasonably,we are sure to benefit more from recreational activities.

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!

as long as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。
