核心问题
____ catch the early bus, he got up at five this morning. A. So that B. So as to C. In order to D. In order that(《高中英语标准化测试》第二册,p.117) 书上给的答案是 C(In order to)。但我认为 B(So as to) 也是正确的。
词典解答
出题者可能认为 so as to 只能用于句尾,而不能用于句首。其实并不是这样。请看下面的实例：
So as to be heard, he spoke through a microphone. (EGS) 为了使人们能听到他讲话，他用了麦克风。
