一、根據(jù)時間狀語與時態(tài)的對應(yīng)關(guān)系 動詞特定的時態(tài)常常與特定的時間狀語聯(lián)系在一起,如由this time yesterday可知用過去進(jìn)行時;由so far, in the past three years, till now可知要用完成時,等等。
1、句中含有yesterday; last year(last + 具體時間); two days ago(一段時間 + ago); just now; this morning; in 2008(in + 過去的年代); the other day; over the weekend等時間狀語時,謂語動詞用一般過去時;

2、句中含有tomorrow; next week(next +具體時間); in two hours(in +一段時間); (how) soon; from now on; 10 years from now(一段時間+from now); in the future; in 2012(in +將來的年代); by (the end of) next month(by+將來時間); for the weekend; this afternoon; this evening; tonight; this weekend等時間狀語時,謂語動詞用一般將來時;

3、句中既有yesterday等過去時間狀語,又有一個具體時間點(at 5:00; this time; at that time)時,謂語動詞用過去進(jìn)行時;

4、句中含有recently; in the last/past two years(in the last/past+一段時間); over the years(over the+一段時間); since 2005(since+具體時間或從句); for two years(for+一段時間,句中無其它時間狀語); before(單獨用于句尾)等時間狀語時,謂語動詞用現(xiàn)在完成時;

5、by (the end of) last year(by+過去時間); two days before(一段時間+before); for和since說明的時間同時用于句中;by the time + 從句(過去時態(tài))等時間狀語時,謂語動詞用過去完成時;

6、簡單句中如不含上述時間狀語或有含說話時間在內(nèi)的表示現(xiàn)在時間關(guān)系的詞語時(如now; today; these days等詞)解析:由時間狀語at this time tomorrow可知用將來進(jìn)行時,故選B。

二、固定句型與動詞時態(tài)間的對應(yīng)關(guān)系 在英語中,不少句型與一些動詞在時態(tài)的運用方面都存在著特定的對應(yīng)關(guān)系,
1.在“祈使句+and/or+陳述句”句型中,陳述句中用will表示的一般將來時;
2.在This/如That/It is t he second time that…句型中用現(xiàn)在完成時,若is改為was,就用過去完成時;
3.在no soon er…than…和hardly…when…句型中,前面常用過去完成時,when/than后的句子用一般過去時;
about to do…when…或was/were doing…when…或was/were on the point of doing…when…句型中,when分句的謂語動詞用一般過時;
5.在一個含有時間狀語從句的主從復(fù)合句中,如果主從句的謂語動詞都是過去發(fā)生的動作,一般來說,表示短暫性動作的動詞用一般過去時,表示持續(xù)性動作的動詞用過去進(jìn)行時;等等。
Let’s keep to the point or we _______ any decisions.
A. will never reach B. have never reached C. never reach D. never reached
解析:這是“祈使句+or +陳述句”句型,陳述句的謂語要用“will+動詞原形”,故選A。

三、根據(jù)某些動詞與時態(tài)的對應(yīng)關(guān)系 在英語里有些動詞與時態(tài)有著特定的對應(yīng)關(guān)系,如see(看見),hear(聽見),find(找到) 等都不可用于進(jìn)行時態(tài);work表示機(jī)器不能正常運行、運轉(zhuǎn)時,常用一般現(xiàn)在時的否定式;open, close, lock等詞表示門、窗等不能正常關(guān)、開、鎖的意思時,常用won’t open /close /lock等,這時它們是以主動形式表示被動意義。
—Can I help you, sir? —Yes. I bought this radio here yesterday, but it _____.
work B. won’t work C. can’t work D. doesn’t work 解析:此處的work是指radio不能正常運行,應(yīng)用一般現(xiàn)在時的否定式,故選D。

四、根據(jù)上下語境來確定時態(tài) 在絕大多數(shù)情況下,動詞的時態(tài)是由上下文來決定的,這就要求我們一方面要熟記各種時態(tài)的適用范圍,另一方面要求我們注意上下文的提示。
— Is this raincoat yours? — No, mine ______ there behind the door.
hanging B. has hung C. hangs D. hung
解析:根據(jù)上下文的提示,hang表示的是目前的狀態(tài),故選A。

五、主從句時態(tài)的一致性原則:主從復(fù)合句可根據(jù)其時態(tài)一致性原則,通過主從句中任意一個句子的時態(tài)確定另外一個句子的時態(tài);含有時間狀語從句的主從句還可通過其引導(dǎo)詞所表示的不同時間關(guān)系,確定主句和從句的時態(tài)。
