摘 要:英語動(dòng)詞時(shí)態(tài)是語法課教學(xué)的重點(diǎn)、難點(diǎn)和易混點(diǎn)。本文介紹一種新的教學(xué)方法——運(yùn)用時(shí)間線對(duì)時(shí)態(tài)進(jìn)行教學(xué),它能夠激發(fā)學(xué)生們的學(xué)習(xí)興趣,使復(fù)雜抽象的動(dòng)詞時(shí)態(tài)變得簡(jiǎn)單、具體、直觀,從而收到事半功倍的效果。
關(guān)鍵詞:動(dòng)詞時(shí)態(tài);時(shí)間線;直觀;興趣
英語動(dòng)詞時(shí)態(tài)是語法課教學(xué)的重點(diǎn)和難點(diǎn)。傳統(tǒng)教學(xué)中教師反復(fù)講解了好多遍(講的口干舌燥),但很多學(xué)生對(duì)動(dòng)詞時(shí)態(tài)仍然概念模糊,理不清頭緒,感覺抽象、枯燥。筆者在長(zhǎng)期的英語教學(xué)實(shí)踐中,嘗試運(yùn)用時(shí)間線對(duì)時(shí)態(tài)進(jìn)行教學(xué),并利用多媒體動(dòng)畫展示,激發(fā)了學(xué)生們的學(xué)習(xí)興趣,使復(fù)雜抽象的動(dòng)詞時(shí)態(tài)變得簡(jiǎn)單、具體、直觀,收到了事半功倍的效果。
一、基本用法介紹
時(shí)間線跟數(shù)學(xué)上的坐標(biāo)軸類似。如下圖所示:先畫一條帶箭頭的橫線,命名為時(shí)間線(Time Line),箭頭方向代表將來(見圖1);取橫線上的中間一處為現(xiàn)在的時(shí)間點(diǎn)(now)(見圖2)。
以此為分界點(diǎn),在它前面的表示將來(future),在它后面的表示過去(past)(圖3)。
二、時(shí)間線在四大類時(shí)態(tài)中的應(yīng)用
動(dòng)詞時(shí)態(tài)(The Tense)其實(shí)是兩個(gè)概念:時(shí)間和狀態(tài),指動(dòng)詞所表示的動(dòng)作發(fā)生的時(shí)間和存在的狀態(tài)。從時(shí)間上劃分可分為四大類:現(xiàn)在時(shí),過去時(shí),將來時(shí)和過去將來時(shí)。
通過下面的時(shí)間線就能直觀的展示出來(見圖4,●表示某時(shí))。
每一類從狀態(tài)上又可分為四種形式:一般式,進(jìn)行式,完成式和完成進(jìn)行式。
(一)現(xiàn)在時(shí)態(tài)
現(xiàn)在時(shí)態(tài)包括:一般現(xiàn)在時(shí),現(xiàn)在進(jìn)行時(shí),現(xiàn)在完成時(shí)和現(xiàn)在完成進(jìn)行時(shí)。
1.一般現(xiàn)在時(shí)
概念:表示現(xiàn)在時(shí)間內(nèi)經(jīng)常發(fā)生的動(dòng)作或存在的狀態(tài)。

Summer comes after spring.
(4) 在時(shí)間和條件狀語從句中,用一般現(xiàn)在時(shí)代替一般將來時(shí)。如:

(5) 表示已決定或計(jì)劃要做(將來)的事,常用于航班、列車時(shí)刻、開學(xué)、開會(huì)、電影開始放映的時(shí)間等。這種用法常用于表示“來、去、開始、結(jié)束”等動(dòng)詞:come, go, begin, start, end, stop, leave, arrive, return, stay, open, close, dine, depart等。如:

(6)用于圖片說明或劇本中的動(dòng)作提示和背景說明。如:
