( ) He was barking ________ let him in.A for someone to B.in case someone C.so someone to D.so that someone
正确答案为A.for someone 是不定式短语to let him in的逻辑主语,本题中for someone to let him in作目的状语.选项B,in case+从句意为“ 以防万一,如果” ,用一般现在时表示将来.如:Bring your umbrella in case it rains.so表示结果,引导句子,选项C,so 一旦出现会加句子,而to 是不定式是非谓语.关键是D选项,so that =in order that引导目的状语从句,在过去时的句子里,从句中要有should或could,本题中无,故D不是正确选项.下面论述引自《牛津英语用法指南》:So that and in order that--- These structues are used to talk about purpose.They can be followed by a present tense with a future meaning.So that is more common than in order that,especially inan informal style.In the past tense,should or could are nornally used after so that and in order that.The conditional (would) is also possible,and might is occasionally used in a literary style.e.g.I'm going to make an early start so that I don't/won't get stuck in the traffic.I took my golf clubs so that I could play at the weekend.
