as long as 和 so long as 的区别是什么？什么时候用？

DZ

　　一、在表示during the whole time that(长达……之久)或while(只要)的含义时,往往用as long as。如:

　　1. They all continued their regard for me as long as they lived. 他们毕生都在关心着我.

　　2. As long as there is life there is hope. 留得生命在,不怕没希望.

　　二、在表示on condition that, provided that或if(只要,如果)的含义时,用as long as或so long as的情况均很常见。

　　三、在表示since, considering that(既然,因为)的含义时,多用as long as。如:

　　1. As long as we've driven this far, we might as well go on. 我们既然已经驶得这么远了,就不妨继续前进.

　　2. As long as you are going, I'll go too. 既然你要去,那么我也去.

　　四、有时,as / so long as与if only同义,由它引导的状语分句可不依附主句而单独使用,表示说话人的希望、愿望或遗憾心情等。如:

　　-It's said it's going to turn colder and freeze later on. 听说过些时候天气要变冷,有冰冻.

　　-As long as it doesn't spoil the weekend. (=I hope that it doesn't spoil the weekend.) 只要不把周末弄糟了就没事.

　　五、在用as / so long as连接的从句中,当其谓语为be,而主语和主句的主语相同时,则从句的主语和be可以省略。如:

　　I'm sure we are safe as long as(we are) in his care. 我深信只要在他的保护下,我们就会平安无事.
