B，表示过去可能发生而实质上未发生的事，用

might+

动词达成式。若可是推断过去可能已经发生的事，则可用

may[might]动词达成式，如Hemay[might]havegone.他可能已经走了。选C。由句意可知。选B，doallonecan意为“全力”或“倾尽全力”。选C，mustn’在t此相当于can’t，且语气更强。选B，“needn’动t+词达成式”的意思是：本来不用做某事，但实质上做了。上句意思是“你本来不用告诉他这个信息的，由于他(当时)已经知道了”。注意，句中knew为过去式。选B，must后接动词达成式表示对过去情况的必然推断，意“必然已经做了某事”。选B，should后接动词达成式表示“本来应当做某事，结果未做”。选B，对过去情况的必然推断，宜用“神情动词+动词达成式”，再依照句意，可确定答案为B。注：can表示推断平常不用于必然句。选A。mayhavedonesth表示对过去可能发生的事进行推断，意为“可能从前”。选C。依照上下文的语境推知。can’意t为“不能够”。14.选B。依照上下文的语境推知。can’表t推断，意为“不不能”。选D。couldn’thavedonesth表示对过去情况进行推断，意为“过去不能能发生过某情况”。选A。依照下文的willbe可知，“他考试再不及格”是将来的事，据此可除去B和D。再依照语意，除去C。选D。从时间上看，由于是昨天没来开会，所以推断他患病也应指昨天，故除去A和C。从语境上看，既然上文说I’mnotsosure，那么说明说话者对自己的推断没有很大掌握，应选D。选C。依照上文的过去时态可知，此句谈的是过去的事，故除去A和C。依照语境除去D。选C。couldn’thavedonesth构造在此表示责怪，指过去本来能够做某事但实质上未做。第二空填waswasted，陈述的是过去的一事实。21.选B。依照下文的I’llphonetheairportandfinditout可知，说话人对自己的推断没有很大掌握，应选might。若选A，语气太强，不合语境;若选D，不合语法习惯，由于can表推断平常不用于必然陈述句中。选D。既然“通行证现在不在口袋里”，那么它“掉出去”应发生在过去，故除去A和B。比较选项C和D所表示的意思，选D更合
