skating2hourscooking1hourTask2現(xiàn)在完成時和現(xiàn)在完成進行時的區(qū)別I1.現(xiàn)在完成時:have+過去分詞表示在某一特定時間之前曾經發(fā)生過的動作,或者到這一時間為止已經完成的動作.2.現(xiàn)在完成進時:have+been+現(xiàn)在分詞

(1)表示從過去某一時間開始一直在進行的動作,并有可能持續(xù)下去,強調動作的全過程；表示從過去到現(xiàn)在的重復性動作。

(2)注意:多用于延續(xù)性動詞，如work,live,study,skate,collect…

概念:動作從過去某一時間開始一直延續(xù)到現(xiàn)在,

并且有可能持續(xù)下去構成:

have/hasbeen+doingsth+常用詞:for+一段時間;since+

e.g.Howlong

since

nineo’clock.現(xiàn)在完成進行時從句(一般過去時)一段時間+ago過去的時間點時間狀語:1.for+一段時間

2.since+過去的時間點

3.since+一般過去時的句子表示動作從過去某一時間開始一直延續(xù)到現(xiàn)在或離現(xiàn)在不遠的時間。其動作是否繼續(xù)下去，由上下文而定。這個時態(tài)多用于延續(xù)性動詞?，F(xiàn)在完成進行時構成：have/hasbeen+V.ing+……Howlonghaveyoubeendoing…?

I’vebeendoing…for…+一段時間since…+一個時間點

+

一段時間+ago

+

從句注意點三：havebeenin,havebeento與havegoneto的用法1、have(has)beenin表示“在某地（多長時間）”，現(xiàn)在仍在那里。常與表示一段時間的狀語連用。例如：Mr.BrownhasbeeninShanghaiforthreedays.布朗來上海已經有三天了。TheyhavebeeninCanadaforfiveyears.他們到加拿大有五年了。2、have(has)beento表示“曾經去過某地”，現(xiàn)在已經不在那里了?？膳cjust,ever,never等連用，例如：Ihavejustbeentothepostoffice.我剛才去郵局了。MaryhasneverbeentotheGreatWall.瑪麗從未去過長城。HaveyoueverbeentoHangzhoubefore?你以前曾經去過杭州嗎？Have(has)beento后面可接次數，表示去過某地幾次。例如：Theyhavebeentothatvillageseveraltimes.他們去過那個村莊好幾次了。3、have(has)goneto意為“到某地去了”，表示到了某地或正在去某地的途中?？傊f話時該人不在現(xiàn)場，例如：----WhereisTom?----Hehasgonetothebookshop.他到書店去了。JackJohnsonhasgonetoLondon.杰克.約翰遜到倫敦去了。動詞的過去分詞的規(guī)則變化，在動詞后加ed，規(guī)則變化有以下四種：

①原形+ed

如：worked,

passed

②詞尾是e時，直接加d

如：liked

lived

③若詞尾為“輔音字母加y”，則改y為i加ed。詞尾為“元音字母+y”時，直接加d；如:

played

stayed

studied

cried

④末尾只有一個輔音字母的重讀閉音節(jié)是，雙寫最后一個輔音字母加ed.如：

stopped

dropped

動詞的過去分詞的規(guī)則變化初中英語不規(guī)則動詞巧記法

英語動詞按其過去式和過去分詞的構成方式可分為規(guī)則動詞和不規(guī)則動詞。規(guī)則動詞的過去式和過去分詞由詞尾加-ed構成，而不規(guī)則動詞的變化因詞而異。但如對不規(guī)則動詞的過去式和過去分詞做一分析，就可發(fā)現(xiàn)其中的“規(guī)則”。為方便同學們記憶，現(xiàn)將初中英語(新目標goforit)中常見的不規(guī)則動詞的原形、過去式和過去分詞列出并規(guī)為五種類型。同學們還可將第四、五類分為若干組，以便準確記憶。一、AAA型（動詞原形、過去式、過去分詞同形）cost（花費）costcostcut（割）cutcuthit（打）hithithurt(傷害）hurthurtlet（讓）letletput（放）putputset（設置）setset

read（讀）

read／red/

／red/二、AAB型（動詞原形與過去式同形）beat（跳動）beat

beaten三、ABA型（動詞原形與過去分詞同形）become（變成）

became

becomecome（來）

camecome四、ABB型（過去式與過去分詞同形）

get（得到）

gotgothold（抓?。?/p>

heldheldsit（坐）

satsatwin（贏）

wonwonmeet（遇見）

metmet

keep（保持）

sleptslept五、ABC型（動詞原形、過去式與過去分詞三者不同形）give（給）gave

go（去）went

gonesee（看見）

非延續(xù)性動詞不能與時間段連用：go/come/begin/start/die/buy/borrow/sell/leave/arrive/receive/become等詞語是瞬間動詞表示的動作是一時的，不能延續(xù)，不能與for、since等表示一段時間的詞連用，也不能用于howlong引導的疑問句中。如不能說：Hehasborrowedthebookfortwomonths.(ⅹ)但可以說：Hehaskeptthebookfor2months.或：Ithasbeen2monthssinceheborrowedthebook.或：Twomonthshaspassedsinceheborrowedthebook.

這些瞬間動詞常與它對應的可以表示時間段的詞語進行互換。become—beborrow—keepbuy—havebegin(start)—beonopen—beopendie—bedeadleave--beawaycome--behere/ingoout—beoutjoin--beamember/beinbegintostudy--study注明：非延續(xù)性動詞在否定結構中可用于現(xiàn)在完成時態(tài)：Ihaven’tboughtanythingfortwodays.Readthefollowingmessage.Thendrawlinestomatchthesnowglobeswiththeirdescriptions.DearJack,Thanksforsendingmethesnowglobeofthemonster.Iloveit.InfactIthinkit’sprobablymyfavorite.I’vebeencollectingsnowglobesforsevenyears,andnowIhave226ofthem.MymomsaysIhavetostop,becausewe’verunoutofroomtostorethem.They’reallaroundourapartment.Ievenstoretheminboxesundermybed.ThefirstoneIevergotwasabirthdaycakesnowglobeonmyseventhbirthday.Iparticularlyloveglobeswithanimals.Ihaveabigonewithbearsinit,andanotheronewithpenguins.Ifyouknowanyoneelsewhocollectsthem,pleasetellme.I’dliketostartasnowglobecollectors’club.Bytheway,what’syourhobby?Love,Ellensendsbsth=sendsthtosb
