核心问题
May I sit nearer ____ I can see more clearly? A. as if B. so that C. even if D. so
《高中英语语法练习手册》(外研社, p.166) 给的答案是 so that。能否选 so 呢?
词典解答
上面的试题有重大失误:在非正式语体中,so 可以代替 so that,引出目的状语从句。例如：
-
They whisper to each other so (that) no one else can hear. 他们彼此小声说话,以免其他人听到他们的谈话。
-
He's going to the lecture early so (that) he'll get a good seat. 他要早点儿去听讲,以便得到一个好座位。
-
The school closes earlier so (that) the children can get home before dark. (目的) 学校提前放学, 让孩子们能在天黑前回家。
-
Leave the door open, so I can hear if anyone comes. 让门开着，以便我能听到是否有人来。
由此看来,下面的试题也是有毛病的(选项 D 和 B 都是正确的):
Let's start earlier ____ we can get there in time.
A. as if B. so
C. even if D. so that(《英语语法练习手册》, 外研社, p.69, 给的答案是 D)
