B，表示過去可能發(fā)生而實質(zhì)上未發(fā)生的事，用

might+

動詞達成式。若可是推斷過去可能已經(jīng)發(fā)生的事，則可用

may[might]動詞達成式，如Hemay[might]havegone.他可能已經(jīng)走了。選C。由句意可知。選B，doallonecan意為“全力”或“傾盡全力”。選C，mustn’在t此相當于can’t，且語氣更強。選B，“needn’動t+詞達成式”的意思是：本來不用做某事，但實質(zhì)上做了。上句意思是“你本來不用告訴他這個信息的，由于他(當時)已經(jīng)知道了”。注意，句中knew為過去式。選B，must后接動詞達成式表示對過去情況的必然推斷，意“必然已經(jīng)做了某事”。選B，should后接動詞達成式表示“本來應當做某事，結(jié)果未做”。選B，對過去情況的必然推斷，宜用“神情動詞+動詞達成式”，再依照句意，可確定答案為B。注：can表示推斷平常不用于必然句。選A。mayhavedonesth表示對過去可能發(fā)生的事進行推斷，意為“可能從前”。選C。依照上下文的語境推知。can’意t為“不能夠”。14.選B。依照上下文的語境推知。can’表t推斷，意為“不不能”。選D。couldn’thavedonesth表示對過去情況進行推斷，意為“過去不能能發(fā)生過某情況”。選A。依照下文的willbe可知，“他考試再不及格”是將來的事，據(jù)此可除去B和D。再依照語意，除去C。選D。從時間上看，由于是昨天沒來開會，所以推斷他患病也應指昨天，故除去A和C。從語境上看，既然上文說I’mnotsosure，那么說明說話者對自己的推斷沒有很大掌握，應選D。選C。依照上文的過去時態(tài)可知，此句談的是過去的事，故除去A和C。依照語境除去D。選C。couldn’thavedonesth構(gòu)造在此表示責怪，指過去本來能夠做某事但實質(zhì)上未做。第二空填waswasted，陳述的是過去的一事實。21.選B。依照下文的I’llphonetheairportandfinditout可知，說話人對自己的推斷沒有很大掌握，應選might。若選A，語氣太強，不合語境;若選D，不合語法習慣，由于can表推斷平常不用于必然陳述句中。選D。既然“通行證現(xiàn)在不在口袋里”，那么它“掉出去”應發(fā)生在過去，故除去A和B。比較選項C和D所表示的意思，選D更合
