题型:不详难度:来源:
We were looking for you all this morning. You    office without a word.
A.mustn’t have leftB.shouldn’t have leftC.couldn’t have leftD.needn’t have left

答案
B
解析

试题分析: 句意:我们一上午都在找你。你不应该一声不吭就离开办公室。must表示推测不用于否定句,排除A选项;shouldn’t have done本不应该做(但做了);couldn’t have done不可能做过;needn’t have done 本没必要做,由句意可知此处表示责怪,选B。
