《大学英语》1998年第8期(p.29)和《大学英语四六级考试全真试题集详解》(航空工业出版社,p.73)对上题的解答如下：
“此句的意思是‘因此他可以赶紧回到玩具旁’。[A]项 so‘因此,所以’,符合题意。”请问上句中的 so 是“因此,所以”的意思吗?
词典解答
尽管我们大家都知道 so(that) 既可以引导结果状语从句(因此,以致,所以),也可以引导目的状语从句(以便……,为了……),但是遇到具体的句子还是会发生误解。从句意来看,上句中的 so 从句肯定是目的状语从句。下面是 so 引导目的状语从句的实例:
Leave the keys out so (that) I remember to take them with me. 把钥匙放在外面，以便我能记着随身携带。
[试题句意]……不要让孩子饭后立即离开餐桌,否则他为了赶忙回去玩玩具就会学会狼吞虎咽地吃饭。
