这几道题都是现在完成时部分的，涉及到延续性动词和非延续性动词的用法以及与之转换的几个句型。

第一题：

1、主语+have/has+done(动词的过去分词)+for+时间段/since---.

=It's/hasbeen+时间段+since从句（从句用一般过去时）.

=时间段+haspassed+since从句（从句用一般过去时）.

例如：这本书我已经买了三天了。

Iboughtthisbookthreedaysago.(buy为非延续性动词不能与时间段连用，但可与一般过去时连用)

=Ihavehadthisbookforthreedays/sincethreedaysago..(buy为非延续性动词用have替换）

=It's/hasbeenthreedayssinceIboughtthisbook.

=ThreedayshaspassedsinceIboughtthisbook.

第一题为句型，故选择A

第二题：自从你离开后她很悲伤。

主语+have/has+done(动词的过去分词)+for+时间段。

=主语+have/has+done(动词的过去分词)+since+时间段+ago.

=主语+(动词的过去分词)+since从句（从句用一般过去时）.

第三题：非延续性动词不能与howlong/for---/since---连用但可与一般过去时连用

gettoknow不延续用know替换

延续性动词与非延续性动词及其转换

动词按其动作发生的方式、发生过程的长短可分为延续性动词与非延续性动词。

一.延续性动词表示能够延续的动作,如：learn,work,stand,lie,know,walk,keep,have,wait,watch,sing,read,sleep,live,stay等。延续性动词可以与表示时间段的状语连用。

表示时间段的短语有:for+一段时间,for2years;since从句,sincehecamehere;since+时间点名词,sincelastyear,since5daysago;howlong;foralongtime等。

二.非延续性动词也称终止性动词、瞬间动词,表示不能延续的动作,这种动作发生后立即结束。如:open,die,close,begin,finish,come,go,move,borrow,lend,buy等。非延续性动词在肯定句中与表示时间点的状语连用，如：twoyearsago;at5o'clock;否定的终止性动词可以与表示时间段的时间状语连用。

三.延续性动词与非延续性动词之间的转换：leave---beaway,borrow---keep,buy---have,begin/start---beon,die---bedead,finish---beover,join---bein+组织机构,beamemberof+组织机构,opensth---keepsthopen,fallill---beill,getup---beup,catchacold---haveacold,comehere---behere,gothere---bethere,become---be,comeback---beback,fallasleep---beasleep,getto/arrive/reach---be(in),leave---beawayfrom,gettoknow---know,go(get)out→beout，puton→wear；catchacold→haveacold等。例:Theoldmandied4yearsago.----Theoldmanhasbeendeadfor4years.----Itis4yearssincetheoldmandied.----Fouryearshaspassedsincetheoldmandied.HejoinedtheParty2yearsago.-----HehasbeeninthePartyfor2years.Iboughtthebook5daysago.----Ihavehadthebookfor5days.
