Iamreadingthebook.完成时

Ihavereadthebook.现在完成进行时

Ihavebeenreadingthebook.现在正在读已经读过过去到截至说话为止，一直在读PresentPerfectContinuous

现在完成进行时由“助动词have(has)+been+动词的ing形式”构成：

Shehasbeenswimming.Ihavebeenthinkingaboutthisproblem.Theyhavebeencookinginthekitchen.PresentPerfectContinuous

现在完成进行时表示从过去某时开始一直延续到说话时还在进行，或可能还要继续下去的动作。它通常和“for…”或“since…”的时间状语连用。

Ihavebeenwaitingforaletterfrommyparents.

Ithasbeenrainingforthreehours.

Wehavebeenstudyingheresince2004.我一直在等我父母的回信。雨已经下了三个小时。我们自从2004年开始一直在这里读书。PresentPerfectContinuous

现在完成进行时2.

表示从过去某时开始，一直延续到说话时刻，可能刚刚结束的动作。

Shehasbeensweepingthestreetallday.Sheistootired.Wehavebeenwaitingforyoufortwohours.Wedon'twanttowaitanylonger.她整天都在扫大街。她太累了。我们已经等了你两小时。我们不想再等了。PresentPerfectContinuous

现在完成进行时肯定句：I/You/They/We+havebeen+动词ing形式*He/She/It+hasbeen+动词ing形式

Ihavebeensittingherealltheafternoon.Hehasbeencollectingallkindsofstampssincehewastenyearsold.

我在这儿坐了一个下午。自十岁起他就开始收集各式各样的邮票。PresentPerfectContinuous

现在完成进行时否定句：主语+have(has)notbeen+动词ing形式Theyhaven'tbeenmeetingeachotherforfiveyears.Hehasn'tbeenteachingheretheseyears.他们已经五年没见过对方。这些年，他没有一直在这教书。PresentPerfectContinuous

现在完成进行时疑问句：Have(Has)+主语+been+动词ing形式

Haveyoubeenwritingabook?Yes,Ihave./No,Ihaven’t.时态对比现在完成进行时与现在进行时比较：

现在完成进行时强调某一动作从过去一直延续到现在；而现在进行时只指目前正在发生的动作。试比较：

Susanhasbeenreadingthatstorybooksincelastnight.

从昨晚开始苏珊就一直在看那本故事书。

Susanisreadingastorybooknow.

苏珊正在看一本故事书。时态对比现在完成进行时和现在完成时比较：⑴有些动词(如：work,study,live,teach等)用现在完成进行时与现在完成时表达的意思差不多。试比较：

Theteacherhasbeenteachingatthisschoolfortenyears.

十年来，那位老师一直在这所学校教书。

Theteacherhastaughtatthisschoolfortenyears.

那位老师在这所学校已经教了十年书了。时态对比⑵英语中的多数动词在这两种时态中表示不同的含义。现在完成时如果不带表示一段时间的状语，就只能表示动作的完成，而现在完成进行时则表示动作的延续。试比较：

Theyhavebuiltanewlab.

他们建造了一幢新的实验室。(表示动作的完成)

Theyhavebeenbuildinganewlab(theseyears).

他们(这几年)一直在建造一幢新的实验室。(无论用时间状语还是不用时间状语，都表示动作的延续)Howlonghaveyoubeen
