1、Unit23 Grammer Learning Aims:（學(xué)習(xí)目標(biāo)）Step1:Revision(知識(shí)回顧)提問(wèn)上節(jié)課學(xué)的部分知識(shí)點(diǎn)。Step2: Check preview（檢查預(yù)習(xí)）Ask some students to translate the sentences in red in the text.Step3:Self-study and Cooperation（自主學(xué)習(xí)與合作探究） 時(shí)態(tài)是英語(yǔ)中一個(gè)重要的語(yǔ)法范疇，它表示不同時(shí)間發(fā)生的動(dòng)作或存在的狀態(tài)以及動(dòng)作發(fā)生或存在的方式。動(dòng)作發(fā)生的時(shí)間可分為現(xiàn)在、過(guò)去、將來(lái)和過(guò)去將來(lái)四種形式，動(dòng)作發(fā)生的方式可分為一般、完成、進(jìn)行和完成進(jìn)行

2、四種形式。將這時(shí)間形式和動(dòng)作方式結(jié)合起來(lái)，就構(gòu)成了以下16種時(shí)態(tài)形式(以do為例)： 一 般完 成進(jìn) 行完 成進(jìn) 行現(xiàn) 在現(xiàn)在一般時(shí)do現(xiàn)在完成時(shí)have done現(xiàn)在進(jìn)行時(shí)is doing現(xiàn)在完成進(jìn)行時(shí)have been doing過(guò) 去過(guò)去一般時(shí)did過(guò)去完成時(shí)had done過(guò)去進(jìn)行時(shí)was doing過(guò)去完成進(jìn)行時(shí)had been doing將 來(lái)將來(lái)一般時(shí)will do將來(lái)完成時(shí)will have done將來(lái)進(jìn)行時(shí)will be doing將來(lái)完成進(jìn)行時(shí)will have been doing過(guò)去將來(lái)過(guò)去將來(lái)一般時(shí)would do過(guò)去將來(lái)完成時(shí)would have don

3、e過(guò)去將來(lái)進(jìn)行時(shí)would be doing過(guò)去將來(lái)完成進(jìn)行時(shí)would have been doing注：構(gòu)成時(shí)態(tài)的助動(dòng)詞be (is, am, are), have (has, have), shall, will 等需根據(jù)主語(yǔ)的變化來(lái)選擇。在這16種時(shí)態(tài)中，其中有8種時(shí)態(tài)是最重要的，也是用得最多的，是初學(xué)者必須要掌握的，它們是一般現(xiàn)在時(shí)(也稱一般現(xiàn)在時(shí))、一般過(guò)去時(shí)(也稱一般過(guò)去時(shí))、一般將來(lái)時(shí)(也稱一般將來(lái)時(shí))、現(xiàn)在進(jìn)行時(shí)、現(xiàn)在完成時(shí)、過(guò)去進(jìn)行時(shí)、過(guò)去完成時(shí)、過(guò)去將來(lái)一般時(shí)(也稱過(guò)去將來(lái)時(shí))，其余的時(shí)態(tài)相對(duì)用得較少。Step4: Doing exercises（課堂檢測(cè)）1When I
