( ) He was barking ________ let him in.A for someone to B.in case someone C.so someone to D.so that someone
正確答案為A.for someone 是不定式短語to let him in的邏輯主語,本題中for someone to let him in作目的狀語.選項(xiàng)B,in case+從句意為“ 以防萬一,如果” ,用一般現(xiàn)在時(shí)表示將來.如：Bring your umbrella in case it rains.so表示結(jié)果,引導(dǎo)句子,選項(xiàng)C,so 一旦出現(xiàn)會(huì)加句子,而to 是不定式是非謂語.關(guān)鍵是D選項(xiàng),so that =in order that引導(dǎo)目的狀語從句,在過去時(shí)的句子里,從句中要有should或could,本題中無,故D不是正確選項(xiàng).下面論述引自《牛津英語用法指南》：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.
