现在完成时（三）当表示动作已经充成并对现在有一定影响时，我们一般用现在充成时。同时，可分别用just,already或yet加以强调或说明。其结构也是：

have/has+动词的过去分词.常用的时间状语有:already,just,

一般置于have/has之后，用于肯定句中；在否定句中则要用yet表示“还，未”。Grammarfor和since在现在完成时中的应用for与since都能与现在完成时连用，但区别较大：（1）for后须接“时间段”

HehasstudiedEnglishforfiveyears.

他学英语5年了。（2）since后须接“时间点”

HehasstudiedEnglishsince1999.

他从1999年开始学英语。（3）二者可以转换

for+一段时间=since+一段时间+agoHehasbeenhereforfiveweeks.=Hehasbeenheresincefiveweeksago.

他到这儿已经有五个星期了。如：HehastaughtheresincehecametoChina.自从他来到中国就在这儿教书。Wehavebeenfriendssincewemetinschool.我们从在学校见面起就成为了好朋友。(4)since能引导时间状语从句(主句用现在完成时，从句用一般过去时)，而for则不能。（5）现在完成时常用句型：①Itis(hasbeen)+时间段+since+时间状语或从句ItisfourdayssincelastFriday.从上周五到现在已经四天了。IthasbeentwoyearssinceJimcametoBeijing.吉姆来北京已经两年了。②Thisisthefirst(second…)timethat+从句

句型中的that从句通常使用现在完成时。如：ThisisthefirsttimethatJennyandDannyhavebeentoChina.这是珍妮和丹妮第一次来屮国。ThisisthethirdtimethatIhaveseenKaren.这是我第三次见到Karen。（6）均须与延续性动词连用，也可以与非延

续性动词的否定式连用。如:Ihaveboughtthiscomputersincefouryearsago.(×)Ihavehadthiscomputersincefouryearsago.(√)Ihaven’tboughtanythingfortwomonths.(√)Ihaven'theardfromhimfor3weeks.(√)非延续性动词和延续性动词的转换leave—beawayborrow—keepbuy—havebegin/start—beondie—bedeadfinish---beoveropensth—keepsthopenfallill—beillgetup—beup,comehere—behere,join—beon+组织机构

/beamemberof+组织机构,gothere—bethere,become—be,comeback—beback,fallasleep—beasleep,getto/arrive/reach—be(in),leave—beawayfrom,gettoknow—know,go(get)out—tieout，puton—wear,catchacold—haveacold,getmarried—bemarried等。Theoldmandied4yearsago.—Theoldmanhasbeendeadfor4years.Itis4yearssincetheoldmandied.—Fouryearshaspassedsincetheoldmandied.HejoinedtheParty2yearsago.—HehasbeeninthePartyfor2years.Iboughtthebook5daysago.—Ihavehadthebookfor5days.例如：（7）二者引出的时间状语往往用howlong提问。—Howlonghaveyouhadthisbook?
