(2) 一般过去时常与表示过去的时间状语或从句连用,如:
yesterday,last week ,in the past ,in 1993,at that time,once,during the war,before,a few days ago,when 等等.
(句子中谓语动词是用一般过去时还是用现在完成时,取决于动作是否对现在有影响)。
Have you had your lunch? 你吃过午饭了吗?(你现在不饿吗?)
Yes,I have. 是的,我已经吃过了。(已经吃饱了,不想再吃了。)
When did you have it? 你是什么时候吃的?(关心的是吃的动作发生在何时。)

Used to do something 表示过去常做而现在已经停止了的习惯动作。
I used to work fourteen hours a day. 我过去常常一天干十四个小时。
I ate it at 6:45。我在六点四十五分吃了。
(3)带有确定的过去时间状语时,要用过去时。如:
yesterday(昨天)、two days ago…(两天前…… )、last year…(去年…)、the other day(前几天)、
once upon a time(很久以前)、 just now(刚才)、in the old days(过去的日子里)、before liberation(解放前…)、
When I was 8 years old(当我八岁时…)、at+一个时间点
Did you have a party the other day?前几天,你们开了晚会了吗?
Lei Feng was a good soldier.雷锋是个好战士。
注:在谈到已死去的人的情况时,多用过去时。

The boy opened his eyes for a moment,looked at the captain,and then died.
那男孩把眼睛张开了一会儿,看看船长,然后就去世了。
(5)表示过去一段时间内经常或反复的动作。常与always,never等连用。
Mrs. Peter always carried an umbrella.彼得太太过去老是带着一把伞。
(只是说明她过去的动作,不表明她现在是否常带着伞。)
比较:
Mrs. Peter always carries an umbrella.彼得太太老是带着伞。
(说明这是她的习惯,表明她现在仍然还习惯总带着一把伞)
Mrs. Peter is always carrying an umbrella.彼得太太 总是带着一把伞。
(表示说话者对这一动作或行为厌烦)
I never drank wine.我以前从不喝酒。
(不涉及到现在,不说明现在是否喝酒)
(6)如果强调已经终止的习惯时要用 used to do(过去常常做,而现在不那样做了)
He used to drink alcohol.他过去喝酒。
(意味着他现在不喝酒了。喝酒这个动作终止了)
I used to take a walk in the morning.我过去是在早晨散步。
(意味着现在不在早晨散步了)
比较:
I took a walk in the morning.我曾经在早晨散过步。
(只是说明过去这一动作)
(7)有些句子,虽然没有表示过去确定时间的状语,但实际上是指过去发生的动作或存在的状态的话,也要用过去时。
I didn''t know you were in Paris.我不知道你在巴黎。
(因为在说话时,我已经知道你在巴黎了。这句话指的是说话之前,所以只能用过去时表示。实际上,这句话暗指:But now I know you are here.)
I thought you were ill.我以为你病了呢。
(这句话应是在说话之前,我以为你病了。但是现在我知道你没病)
一变:肯定句变为否定句
技巧1.当句中含有情态动词或助动词could,would,should等时,可直接在其后面加not构成否定句。例如:
I could get you a concert ticket. → I could not / couldn't get you a concert ticket.
技巧2.当句中含有系动词was,were 时,可直接在其后加not构成否定句。例如:
I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.
技巧3.当句中谓语是除情态动词、助动词、系动词was, were以外的动词时,在该动词之前加did not / didn't,动词还原,构成否定句。例如:
The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.
二变:陈述句变为一般疑问句
技巧1.移动词语的位置。将was,were, could,would,should等移到句首。例如:
He could pack his things himself. → Could he pack his things himself?
技巧2.添加助动词did。谓语是除情态动词、助动词、系动词was, were以外的动词时,在主语之前加did,动词还原。例如:
Mr Li looked very old. → Did Mr Li look very old?
三变:陈述句变为特殊疑问句
技巧1.确定疑问词:人who / whom,物what,地点where,时间when / what time,原因why,频率how often,长度how long,距离how far等等。例如:
They gave the concert last night. → When did they give the concert?
技巧2.辨认结构形式:疑问词+情态动词/助动词/ was / were / did +主语+...? 例如:
The accident happened near the station. → Where did the accident happen?
考点名称:实义动词的单数第三人称形式
在一般现在时的肯定句中,当主语为非第三人称单数时,谓语动词用原形;
当主语为第三人称单数时,谓语动词用单数第三人称形式。- 实义动词的一般现在时的单数第三人称形式遵从“s,es, ies”六字母规则。如下表所示:
规则 动词原形 第三人称
单数形式s 一般在词尾加s(读音规则:
清清浊浊元浊,
在清辅音后读清辅音/s/,
在浊辅音和元音后读/z/)stop
take
clean
play
growstops/s/
takes/s/
cleans/z/
plays/z/
grows/z/es 以,x,ch,sh,或o结尾的动词
加-es(读/iz/)pass
fix
wash
watch
dopasses
fixes
washes
watches
doesies 以辅音字母
加y结尾的动词,变y为ies(读/iz/)fly
carry
hurryflies
carries
hurries
注意:不规则变化的有have—has, be—is, go—goes, do—does 一般现在时,当主语是第三人称单数时,谓语动词要用第三人称单数形式
主语是第三人称单数有以下几种情况:(1) 不可数名词做主语:
Some water is in the glass(2) 单个的可数名词做主语:
The girl is Chinese. My watch is on the dresser.
(3) He ,she , it 等代词单个做主语:
He is in the tree. She likes her family very much.
(4) 单个的人名,地名或称呼作主语:
Mary is a doctor. Uncle Li speaks a little English.
Changchun is a beautiful city.(5) 指示代词this, that 等作主语:
This is a pear. That is an apple .(6) Everyone, everything ,something, nobody, nothing.等不定代词作主语时
Is everyone here today? Everything is ok .(7)单个数字作主语时:
”8” is a good number in China.
动词单数第三人称形式的一般现在时的句子的否定句、疑问句及特殊疑问句。 <?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />否定句:
在主语的后面实义动词前加doesn’t(注意实义动词应恢复原形。)主语(单三)+doesn
