確定句子時(shí)態(tài)的三大訣竅

1、確定句子時(shí)態(tài)的三大訣竅要迅速、準(zhǔn)確地確定句子的時(shí)態(tài)有時(shí)是比較困難的。無(wú)論是作動(dòng)詞時(shí)態(tài)填空題還是單項(xiàng)選擇題，掌握好動(dòng)詞時(shí)態(tài)的幾種基本用法對(duì)于學(xué)好英語(yǔ)至關(guān)重要。如能對(duì)所學(xué)的幾種時(shí)態(tài)運(yùn)用自如，則可以迅速地提高英語(yǔ)寫(xiě)作能力，中學(xué)生英語(yǔ)寫(xiě)作中的錯(cuò)誤大多都與時(shí)態(tài)有關(guān)。學(xué)好動(dòng)詞的時(shí)態(tài)是一個(gè)漫長(zhǎng)的過(guò)程，要靠平時(shí)逐漸積累語(yǔ)法知識(shí)，細(xì)心體會(huì)，但掌握規(guī)律，總結(jié)經(jīng)驗(yàn)也是十分重要的。     要確定一個(gè)動(dòng)詞在具體的句子中到底用什么樣的時(shí)態(tài)，首先是理解各種時(shí)態(tài)的概念、其語(yǔ)法形式和基本用法，其次是要記住與各種時(shí)態(tài)經(jīng)常配合使用的時(shí)間狀語(yǔ)及相關(guān)的信息詞，如at this time yes

2、terday經(jīng)常與過(guò)去進(jìn)行時(shí)態(tài)連用；often，always經(jīng)常與一般現(xiàn)在時(shí)態(tài)或一般過(guò)去時(shí)態(tài)連用；yet常與現(xiàn)在完成時(shí)態(tài)連用；Look！或Listen！暗示其后的句子應(yīng)該用現(xiàn)在進(jìn)行時(shí)態(tài)等等。也就是說(shuō)，在沒(méi)有上下文的情況下常要靠時(shí)間狀語(yǔ)或相關(guān)的信息詞來(lái)確定句子的時(shí)態(tài)，所以確定句子時(shí)態(tài)的第一個(gè)要訣是：     一、簡(jiǎn)單句，最基本，時(shí)間狀語(yǔ)是線索，信息詞匯要留心。     例1Mr King taught（teach）us English last term      例2His

3、unclein three days     Areturns Bhas returnedCreturned Dwill return     例3Listen！Some of the girls about Harry PotterLet's join them ！     Aare talking BtalkCwill talk Dtalked     一個(gè)并列句，如果兩個(gè)分句的謂語(yǔ)動(dòng)詞在同一時(shí)間發(fā)生（過(guò)去、現(xiàn)在或?qū)?lái)），前

4、后兩分句的時(shí)態(tài)應(yīng)保持一致；如果兩個(gè)分句的謂語(yǔ)動(dòng)詞表示不同時(shí)間的動(dòng)作或狀態(tài)，則前后兩個(gè)分句的時(shí)態(tài)就不一樣。所以確定并列句謂語(yǔ)動(dòng)詞的時(shí)態(tài)關(guān)鍵是要分析謂語(yǔ)動(dòng)詞所表示的動(dòng)作或狀態(tài)發(fā)生或存在的時(shí)間關(guān)系，故確定句子時(shí)態(tài)的第二個(gè)訣竅是：     二、并列句，前后看，時(shí)間關(guān)系是關(guān)鍵。     例4I often my homework after supperBut yesterday evening，ITV      Ado，watch Bdid，watchedCdid，watc

5、h Ddo，watched     例5Tom to bed early but his brother doesn't     Agoes Bwent Chas gone     例6He turned off the light then      Aleaves Bleft Cwill have     復(fù)合句是由一個(gè)主句和一個(gè)或一個(gè)以上的從句構(gòu)成的，故主、從句之間有一種時(shí)態(tài)呼應(yīng)關(guān)系

6、。如果主句是一般現(xiàn)在時(shí)態(tài)，則賓語(yǔ)從句根據(jù)需要選擇相應(yīng)時(shí)態(tài)；如果主句是一般過(guò)去時(shí)態(tài)，則賓語(yǔ)從句用一般用過(guò)去時(shí)態(tài)，即一般過(guò)去時(shí)態(tài)，過(guò)去進(jìn)行時(shí)態(tài)，過(guò)去將來(lái)時(shí)態(tài)或過(guò)去完成時(shí)態(tài)。有時(shí)語(yǔ)法規(guī)則并不能概括所有的語(yǔ)言現(xiàn)象，所以一些習(xí)慣用法必須遵循。如果賓語(yǔ)從句表示的是不受時(shí)間限制的客觀真理，盡管主句是一般過(guò)去時(shí)態(tài)，賓語(yǔ)從句也得用一般現(xiàn)在時(shí)態(tài)；when，as soon as， until等引導(dǎo)的時(shí)間狀語(yǔ)從句或if引導(dǎo)的條件狀語(yǔ)從句，通常用一般現(xiàn)在時(shí)態(tài)表示將來(lái)。其基本格式是：一般將來(lái)時(shí)態(tài)的陳述句或祈使句時(shí)間或條件狀語(yǔ)從句。還需要注意積累一些其它的時(shí)態(tài)搭配關(guān)系。故確定句子時(shí)態(tài)的第三條訣竅是：  

7、   三、復(fù)合句，句套句，動(dòng)詞時(shí)態(tài)要呼應(yīng)，習(xí)慣用法須記清。     例7She didn't tell us      Ahow old the patient was Bhow old was the patient     Chow old the patient is  Dhow old is the patient     例8When will you tell him the good
