例如：Bothhisparentslooksad.Maybethey____what'shappenedtohim.Ａ.knewＢ.haveknownＣ.mustknowＤ.willknow（2011天津）

简析：现在完成时主要强调过去发生的动作对现在造成的影响，重点在于对现在的影响。虽说是过去发生的，但没有具体的表示过去的时间状语。这种考查难度较大，往往无时间状语，需要从上下文分析、推理才行。Ｂ中考考点：考点一：考查基本概念1简析：现在完成时主要强调过考点二：考查时间状语

Ａ.willseeＢ.haveseenＣ.sawＤ.seeＢＣＤＣＣＣＢ考点二：考查时间状语

例1.Hehas____

简析：现在完成时的时间状语常有如下四类：

⑴现在完成时常与already（已经），just（刚刚，正好），ever（曾经），never（从不），before（以前），yet（已经、尚、还）等连用。

⑵现在完成时常与recently（近来），sofar（到目前为止），inthepast/“last+一段时间”等时间状语连用。因为上述短语表示的是从现在起往前推算的一段时间，句中的动作是从过去某一时间或时刻开始持续到现在的。

⑶现在完成时时常与“for+时间段或since+过去时间点”连用（含从句，从句过去时）。

⑷现在完成时还与once（一次），twice（两次），threetimes（三次），severaltimes（几次）等表示重复次数的词语连用。简析：现在完成时的时间状语常有如下四类：考点三：考查与一般过去时的区别

例1.—ThesefarmershavebeentotheUnitedStates.

—Really?When___there?

Ａ.willtheygoＢ.didtheygo

Ｃ.dotheygoＤ.havetheygone

例2.—______you___yourhomeworkyet?

—Yes.I_____itamomentago.

Ａ.Did;do;finished

B.Have;done;finished

Ｃ.Have;done;havefinishedＤ.will;do;finish

简析：现在完成时与一般过去时容易混淆，就是因为它们所表示的动作都发生在过去，但二者又有区别：一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作，说话的侧重点在于陈述一件过去的事情，与现在没有关系，一般有表示过去的时间状语；现在完成时表示与现在有关系的发生在过去的动作，它不与表示过去的时间状语（如yesterday,lastweek,amomentago等）连用。BB考点三：考查与一般过去时的区别

简析：现在完成时中，非延续性动词不能与for和since引导的表示一段时间的状语连用，通常是用相应的延续性动词或表示状态的词来代替。常用的延持续性动词及替代形式如下：简析：现在完成时中，非延续性动词不能与fo5.短暂动词和延续动词转换非延续性动词延续性动词buyborrowcomego/leaveopen/closebegin/startend/finishdiecatchacoldbecomeinterestedingetmarriedhavekeepbeenherebeenaway(from)beenopen/beclosedbeenonbeenoverbeendeadhaveacoldbeeninterestedinbeenmarried5.短暂动词和非延续性动词延续性动词buyborrowcom非延续性动词延续性动词putongetupwakeupfallasleepjoinarrive/reachwearbeupbeawakebeasleepbein=beamemberofbein/at非延续性动词延续性动词putongetupwakeup1.【2011．云南昆明】51.Lanmon______hereforalmosttenyearsandhehasmanyChinesefriends.hasbeenB.leftC.hascomeD.came2.【2011四川泸州】47.Mr.Fan___thiswatchin2005.he____itfor6years.A.bought,hashadB.bought,hasC.hasbought,hashadD.hasbought,had3.【2011广东肇庆】41.Youaretoolate.Thefilm______sincehalfanhourago.hasbegunB.hasbeenonC.beganPractice:AAB1.【2011．云南昆明】51.Lanmon_____考点五：考查词组have/hasbeenin/to与have/hasgoneto的区别
