题目内容
【题目】----- Did you buy the dictionary?
---- No. My lost dictionary was found, so I ________ a new one.
A. didn’t need to buy B. needn’t have bought
C. shouldn’t have bought D. mustn’t have bought
【答案】A
【解析】
试题分析:考查实义动词用法;need在这里作为实义动词,后面的宾语可以是名词、动名词、动词不定式或代词,这种情况下,need既可用于肯定句,也可用于否定句和疑问句,构成否定句和疑问句时要借助于助动词do或does. 回话者句意:没有。我丢的词典被找到了,所以我不需要买一个新的。故选A
