1.for as long as 的for
问题描述：
1.for as long as 的for
1.for as long as 的FOR在其中的结构,是怎么用,第一次见FOR在 as long as 前,不怎么理解
2.BETTER YET是怎么用
答
1.for as long as 是 for long（长久）用在比较句中的的扩展,如：
He has looked forward to seeing her for long.长久以来他一直盼望见到她.
扩展为：He has looked forward to seeing her for (as) long (as he can await).在就他能够等候的限度一直盼望见到她.
2.yet 是副词,与比较级连用加强比较程度,意思是“还要如何”,作用同 still,much,far,even 等副词差不多,多放在形容词或副词前,不同是 yet 也可以放在后面,如：
You must work yet harder.（harder yet） 你工作还要加把劲.
It is yet better (better yet) than the other one.这个比那一个还要好.
