:①Ihaveneverheardofthatbefore.②Haveyoueverriddenahorse?③Shehasalreadyfinishedthework.④Haveyoumilkedthecowyet?Yes,Ihavedonethatalready.⑤I’vejustlostmysciencebook.有时没有时间状语;多是一般疑问句。(2)现在完成时表示过
去已经开始,持续到现在,也许还会持续下去的动作或状态。可以和表示从过去某一时刻延续到现
在(包括现在在内)的一段时间的状语连用。如:for和since,以及sofar,now,today,
thisweek(month,year)等。①Ihaven’tseenherthesedays.②ShehaslearntEnglishfor3years.③Theyhavelivedheresince1990.④WhathashappenedtotheUSAinthelast350years?注意:表示短暂时间动作的词,如

可延续)HejoinedtheLeaguethreeyearsago.(三年前入团,joined为短暂行为。
)注意:句子中如有过去时的时间副词(如yesterday,lastweek,in1960)时,不能使用现
在完成时,要用过去时。例如:(错)Tomhaswrittenalettertohisparentslast
