isfallingD wasfalling 答案为A inthepasttwoyears意为 在过去的两年里 最常与其搭配的时态就是现在完成时 通常句中有时间状语inthepast previous years centuries days时 要用现在完成时 2 Customersareaskedtomakesurethatthey therightchangebeforeleavingtheshop A willgiveB havebeengivenC havegivenD willbegiven 答案为B give后接双宾语 therightchange作直接宾语 customers作间接宾语 所以当customers作主语时 谓语动词要用被动语态 根据句意顾客被要求在离开商店前确认已被找零 表示某事发生前已经完成的动作 故使用完成时态 3 Myfriend who ontheInternationalOlympicCommitteeallhislife isretiringnextmonth A servedB isservingC hadservedD hasserved 答案为D 时间状语allhislife表示一段时间 由后面一句下个月将退休 可知allhislife表示的是从之前某个时间开始到现在的一段时间 故用现在完成时 表示从过去直到现在一直持续的动作 4 We ournewneighborsyet sowedon tknowtheirnames A don tmeetB won tmeetC haven tmetD hadn tmet 答案为C yet在这里几乎是使用完成时态的标志 根据句意又可以推断出前半句的意思是我们到现在还没有见过新邻居 故使用现在完成时 现在完成时在此表示过去发生的某一动作对现在造成的影响 5 Iwon ttellthestudenttheanswertothemathproblemuntilhe onitformorethananhour A hasbeenworkingB willhaveworkedC isworkingD hadworked 答案为A 由句意可知 在学生研究这道题目的时间满一个小时之前 我 都不会告诉他答案 从句意推断 这里强调的是动作持续一段时间而且还在进行 所以应该用现在完成进行时 6 Thepowerstation electricityforthecityforthreeyearsandtheircooperationwillcontinue A providedB wasprovidingC providesD hasbeenproviding 答案为D 理解句意 这家电厂为这个城市供电三年了 它们的合作还会继续 forthreeyears确定了要使用完成时态 现在完成进行时在此句中表示过去的动作持续到现在 而且还将继续进行 7 He foraprojectinRussiainthelastthreemonthsandhewillreturnhomesoon A hadworkedB worksC hasbeenworkingD isworking 答案为C 在本题中inthelastthreemonths决定了要使用完成时态 从句意中可以推断出此处不是以过去某个时间点为基点的 故不用过去完成时 现在完成进行时在本句中表示从过去一直持续到现在 刚刚或即将停止的动作 8 Sinceshesawtheoldfilmlastweek she theoldsongformanydays A issingingB hasbeensingingC singsD sang 答案为B 从since和formanydays可看出要使用完成时态 现在完成进行时在此处表示从过去持续到现在重复出现的动作 Homework 1 Searchforinformationaboutcleanmachines 2 Finishthedesignofyoursolarcars
