【一般過去時】
1. 一般過去時的定義

What did you do yesterday? 昨天你干了什么?
I met Lin Tao this morning. 今天上午我會到了林濤。
I was there a moment ago. 剛才我在那兒。
2. 一般過去時的應用
(1) 表示過去某時所發(fā)生的動作或存在的狀態(tài)。如:
Liu Ying was in America last year. 劉英去年在美國。
Jim rang you just now. 吉姆剛才給你打了電話。
(2) 表示過去經(jīng)?;蚍磸桶l(fā)生的動作。常接時間副詞often, usually, always, sometimes, every day / week, etc. 如:

We usually played together. 我們通常一起玩。
3. 一般過去時對謂語動詞的要求
[page]
一般過去時的謂語動詞要用動詞的過去式。動詞過去式的構成分規(guī)則變化和不規(guī)則變化兩種形式,不規(guī)則變化通常需要逐個記憶,規(guī)則變化則遵循以下原則:
(1) 一般在動詞后加-ed。如:play—played, offer—offered, weigh—weighed, destroy— destroyed, sign—signed.
(2) 在以字母e結尾的動詞后,只加-d。如:like—liked, provide—provided, hate — hated, date—dated。
(3) 在以“輔音字母+y”結尾的動詞后,則改y為i,再加—ed。如:supply—supplied, fly—flied, study— studied.
(4) 在以單短元音的重讀閉音節(jié)結尾且,末尾只有一個輔音字母的動詞后,雙寫最后一個輔音字母,再加-ed。如:plan—planned, refer—referred, regret—regretted, ban—banned.
4. 特別說明
有些動詞的過去時,如:expect, hope, intend, plan, wanted 等一般過去時,后接不定式的完成時;或它們的過去完成時接不定式的一般式,都可表示過去未曾實現(xiàn)的意圖、打算或希望。如:
I hoped to have been invited to his wedding party. —I had hoped to be invited to his wedding ceremony. 我本希望他來邀請我參加他的婚禮。
I intended to have joined their games. —I had intended to join their games. 我本打算參加他們的比賽。
【現(xiàn)在完成進行時】
1. 現(xiàn)在完成進行時的定義
現(xiàn)在完成進行時表示某動作從過去某個時間開始,一直延續(xù)到現(xiàn)在,并且還有可能持續(xù)下去。如:
We have been waiting for him for two hours. 我們等他等了兩個小時。
2. 現(xiàn)在完成進行時的結構
現(xiàn)在完成進行時由“have /has been + 現(xiàn)在分詞”構成。
3. 現(xiàn)在完成進行時的應用
現(xiàn)在完成進行時所用的時間狀語:this month / week / year, these days, recently / lately, in the past few + 時間段, since +時間點, for + 時間段。如:
They have been building the bridge for two month. 兩個月來他們一直在修橋。
They have been planting trees this month. 這個月來他們一直在植樹。
4. 現(xiàn)在完成進行時與現(xiàn)在完成時的區(qū)別
(1) 現(xiàn)在完成時強調(diào)動作的完成,而現(xiàn)在完成進行時強調(diào)動作的延續(xù),因此,表示動作的完成,只能用現(xiàn)在完成時,而不能用現(xiàn)在完成進行時。如:
He has changed his idea. 他改變了想法。
(2) 在表示動作的延續(xù)時,雖然既可用現(xiàn)在完成時,也可用現(xiàn)在完成進行時,但現(xiàn)在完成進行時強調(diào)動作的進行。因此在需要明確表示動作還要持續(xù)下去時,應用現(xiàn)在完成進行時。如:
We have been studying here for two years. 我們在這兒已經(jīng)學習了兩年了。
(3) 有些延續(xù)性動詞(如 keep, learn, live, stay, study, work等),用于現(xiàn)在完成時或現(xiàn)在完成進行時的區(qū)別不大。如:
I have lived here for many years.=I have been living here for many years. 我在這兒住了多年了。
