8BUnit1Grammar導(dǎo)學(xué)案
教案課件是老師需要精心準(zhǔn)備的，到寫(xiě)教案課件的時(shí)候了。在寫(xiě)好了教案課件計(jì)劃后，才能夠使以后的工作更有目標(biāo)性！有沒(méi)有好的范文是適合教案課件？以下是小編收集整理的“8BUnit1Grammar導(dǎo)學(xué)案”，希望能為您提供更多的參考。
8BUnit1PastandpresentGrammar
1.識(shí)記動(dòng)詞的過(guò)去分詞形式。
2.能夠在語(yǔ)境中正確運(yùn)用現(xiàn)在完成時(shí)。
3.運(yùn)用現(xiàn)在完成時(shí)談?wù)摪l(fā)生在過(guò)去并與現(xiàn)在有聯(lián)系的事情。
4.理解并運(yùn)用常與現(xiàn)在完成時(shí)連用的時(shí)間表達(dá)方式。
1.四會(huì)內(nèi)容
詞匯：repairvt.sentencen.yetadv.recentlyadv.centuryn.
everadv.justadv.ownvt.
詞組：infactbytheway
句型：EddiehaslivedwithMilliesincehewasborn.
EddiehaslivedwithMillieforfouryears.
Haveyouseenanyexhibitionsrecently?
2.三會(huì)內(nèi)容
詞匯：exhibitionn.titlen.
一、在課文中劃出下列短語(yǔ)并翻譯。
1.bytheway_________________________2.infact____________________________
3.repairovertenbicycles_______________
5.forgetthetitle_______________________
7.overthepastcentury_________________
9.Iwon’tmissitthistime.______________
11.differentformsoftransport___________
4.seesomeexhibitions_________________
6.thechangesinBeijing________________
8.pastandpresent_____________________
10.haveacold________________________
12.ownaboat________________________
二、認(rèn)真閱讀課本P13-17，寫(xiě)出下列動(dòng)詞的過(guò)去式和過(guò)去分詞。
move________________
make________________
learn________________
give________________
play________________

come________________
finish________________
watch________________
forget________________
know________________
repair________________
travel________________
write________________
read________________
live________________
see________________
eat________________
put________________
be________________
go________________
do________________
三、語(yǔ)法小貼士。
現(xiàn)在完成時(shí)
(一)現(xiàn)在完成時(shí)的定義
現(xiàn)在完成時(shí)是表示在過(guò)去發(fā)生但與現(xiàn)在情況有聯(lián)系的動(dòng)作或狀態(tài)的時(shí)態(tài)。
(二)現(xiàn)在完成時(shí)的構(gòu)成
助動(dòng)詞have/has+P.P.(動(dòng)詞的過(guò)去分詞)
1．過(guò)去分詞的構(gòu)成
1)規(guī)則變化。與動(dòng)詞過(guò)去式的變化一樣，在動(dòng)詞詞尾加-ed。
e.g.clean-________close-________stay-________study-________drop-________
2)不規(guī)則變化。見(jiàn)課本P121不規(guī)則變化動(dòng)詞表，需要同學(xué)們逐個(gè)記憶。
2．基本句型結(jié)構(gòu)
1)肯定句：主語(yǔ)+have/has+過(guò)去分詞+…
2)否定句：主語(yǔ)+havenot(haven’t)/hasnot(hasn’t)+過(guò)去分詞+…
3)一般疑問(wèn)句：Have/Has+主語(yǔ)+過(guò)去分詞+…?
Yes,主語(yǔ)+have/has.No,主語(yǔ)+havenot(haven’t)/hasnot(hasn’t).
4)特殊疑問(wèn)句：特殊疑問(wèn)詞+have/has+主語(yǔ)+過(guò)去分詞+…?
注：當(dāng)主語(yǔ)為第三人稱單數(shù)時(shí)，助動(dòng)詞用has。
[練一練]改寫(xiě)下列句子。
1)Theyhavefinishedtheirhomework.
否定句：__________________________________________________________
一般疑問(wèn)句并肯定回答：____________________________________________
2)Johnhasplayedthisgameafewtimes.
否定句：__________________________________________________________
一般疑問(wèn)句并否定回答：____________________________________________
對(duì)劃線部分提問(wèn)：__________________________________________________
(三)現(xiàn)在完成時(shí)的用法
1．用法一：表示過(guò)去發(fā)生或已完成的某一動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果。
并且此影響或結(jié)果現(xiàn)在仍然存在。
常與下列時(shí)間狀語(yǔ)連用：already(已經(jīng)),yet(還/還未),ever(曾經(jīng)),never(從來(lái)沒(méi)有),just(剛才),recently(最近),before(以前),once,twice,manytimes,howmanytimes等。
[練一練]譯一譯，填一填，體會(huì)并操練。
1)I________already________(do)myhomework.
2)Mybrother________never________(read)thisstorybefore.

如：for,since(自…以來(lái)),recently,thisweek,thesedays,untilnow,sofar(迄今為止),over/duringthelastthreeyears/inthepastthreeyears(最近三年來(lái))。

1．一般過(guò)去時(shí)只表示過(guò)去的動(dòng)作或狀態(tài)，與現(xiàn)在無(wú)關(guān)。它常和確定的表示過(guò)去的時(shí)間狀語(yǔ)連用。如：lastweek,yesterday,in1980,…ago,justnow,whenIcamein。
現(xiàn)在完成時(shí)表示過(guò)去發(fā)生的某一動(dòng)作對(duì)現(xiàn)在造成的影響，或從過(guò)去一直持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)，強(qiáng)調(diào)的是現(xiàn)在。它不能和明確指出過(guò)去的時(shí)間狀語(yǔ)連用。
e.g.1)Ihavecleanedtheblackboard.(說(shuō)明現(xiàn)在黑板是干凈的)
Icleanedtheblackboardhalfanhourago.(強(qiáng)調(diào)過(guò)去的行為，與現(xiàn)在無(wú)關(guān))
2)Theteacher________just________(write)somenewwordsontheblackboard.
Theteacher__________(write)somenewwordsontheblackboardjustnow.

e.g.---When________you________(lose)yourcat?---I________(lose)itlastnight.
---Where________you________(find)it?---I________(find)itinthegarden.
