11、成式，如 He may might have gone. 他可能已經(jīng)走了。4. 選C。由句意可知。5. 選B，do all one can 意為“盡力”或“竭盡全力”。6. 選C，mustnt 在此相當(dāng)于 cant，且語氣更強。7. 選B，“neednt + 動詞完成式”的意思是：本來不必做某事，但實際上做了。上句意思是“你本來不必告訴他這個消息的，因為他(當(dāng)時)已經(jīng)知道了”。注意，句中 knew 為過去式。8. 選B，must 后接動詞完成式表示對過去情況的肯定推測，意為“一定已經(jīng)做了某事”。9. 選B，should 后接動詞完成式表示“本來應(yīng)該做某事，結(jié)果未做”。10. 選B，對過去情況的

12、肯定推測，宜用“情態(tài)動詞 + 動詞完成式”，再根據(jù)句意，可確定答案為B。注：can 表示推測通常不用于肯定句。12. 選A。may have done sth 表示對過去可能發(fā)生的事進行推測，意為“可能曾經(jīng)”。13. 選C。根據(jù)上下文的語境推知。cant 意為“不能”。14. 選B。根據(jù)上下文的語境推知。cant 表推測，意為“不不能”。16. 選D。couldnt have done sth 表示對過去情況進行推測，意為“過去不可能發(fā)生過某情況”。17. 選A。根據(jù)下文的 will be 可知，“他考試再不及格”是將來的事，據(jù)此可排除B和D。再根據(jù)語意，排除C。18. 選D。從時間上看，由于

13、是昨天沒來開會，所以推測他生病也應(yīng)指昨天，故排除A和C。從語境上看，既然上文說 Im not so sure，那么說明說話者對自己的推測沒有很大把握，故選D。19. 選C。根據(jù)上文的過去時態(tài)可知，此句談的是過去的事，故排除A和C。根據(jù)語境排除D。20. 選C。couldnt have done sth 結(jié)構(gòu)在此表示責(zé)備，指過去本來可以做某事但實際上未做。第二空填 was wasted，陳述的是過去的一事實。21. 選B。根據(jù)下文的 Ill phone the airport and find it out 可知，說話人對自己的推測沒有很大把握，故選 might。若選A，語氣太強，不合語境;若選D，不合語法習(xí)慣，因為can 表推測通常不用于肯定陳述句中。22. 選D。既然“通行證現(xiàn)在不在口袋里”，那么它“掉出去”應(yīng)發(fā)生在過去，故排除A和B。比較選項C和
