以下是引用麻集爱在2004-3-21 13:23:00的发言:
“时态呼应:本题也可以看出来:表示将来的情况,一般主句用将来时,儿从句一般用现在时。 当while 表示转折,这时候前后两部分并列, rise 应该用 原形 对应 前面的(will )dope 。”
While as conjunction:
1. a : during the time that, *take a nap while I'm out*
b : as long as, provided that, *while there's life there's hope*
2. a : when on the other hand : WHEREAS *easy for an expert, while it is dangerous for a novice*
b : in spite of the fact that : ALTHOUGH *while respected, he is not liked*
3. similarly and at the same time that *while the book will be welcomed by scholars, it will make an immediate appeal to the general reader?*
the rate of addition to arable lands will drop while the rate of loss rises. While是什么连词,应该从句意和时态上判断。按照上面authoritative解释,逐类判断:
在loss rises发生过程中,addition will drop? As long as loss rises,addition will drop?(好象loss发生在后,并非前提条件,)
虽然loss rises,addition will drop?(很明显不对,排除)
loss rises的同时,addition will drop?(从发生时间和变化方向上看,没有similarly和simultaneously的地方,排除)
所以,这样理解好一些:the rate of addition to arable lands will drop during the time that the rate of loss rises. (在这里,loss是指损失,还是减少—reduction,lessening?)
对麻集的观点,保留意见:
1、og中只发现在条件状语从句中,有“一般主句用将来时,儿从句一般用现在时”说法。 2、时态要符合实际需要/句意,可不并列。参考:og 160.While some propose , others suggest , and still others are calling.
