 英语时态之一般过去时讲解

一．一般过去时的基本用法

1．一般过去时表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用。

1. yesterday或以其构成的短语：yesterday morning(afternoon, evening)等；

2. 由“last+一时间名词”构成的短语：last night, last year (winter, month, week)等； 3. 由“时间段+ago”构成的短语：a moment ago, a short time ago, an hour ago等； 4. 其它：just now等

5. 由某些表示过去时态的从句等：when I was ten years old. 如：he was late yesterday.

I did my homework three hours ago.

I came home just now.

二．一般过去式的构成形式 1．Be动词在一般过去时中的变化：

⑴am 和is在一般过去时中变为was。（was not=wasn't） ⑵are在一般过去时中变为were。（were not=weren't）

⑶带有was或were的句子，其否定、疑问的变化和is, am, are一样，即否定句在was或were后加not，一般疑问句把was或were调到句首。 2．句中没有be动词的一般过去时的句子

否定句：didn't +动词原形，如：Jim went home yesterday.

Jim didn't go home yesterday.

一般疑问句：在句首加did，句子中的动词过去式变回原形。

如：Jim went home yesterday.

Did Jim go home yesterday?

特殊疑问句：⑴疑问词+一般疑问句？如：Jim went home yesterday. Did Jim go home yesterday?

What did Jim do yesterday? 肯定式 I worked He(she,it) worked We worked You worked They worked

疑问式 Did I work? Did he(she,it) work? Did we work? Did you work? Did they work?

否定式

I did not work He (she,it)did not work We did not work You did not work They did not work

疑问否定式 Did I not work? Did he(she,it)not work?

Did we not work? Did you not work? Did they not work?

三、规则动词的过去式

1.一般情况下，在动词原形后面加-ed。

look→looked play→played start→started visit→visited

2.以不发音e结尾的动词，在词尾直接加-d。 live→lived use→used

3.以“辅音字母+ y”结尾的动词，先将 y 改为i ,再加 –ed。 study→studied try→tried fly→flied

4.以重读闭音节（即辅音＋元音＋辅音）或r音节结尾，末尾只有一个辅音字母的动词，要先双写这个辅音字母后，再加 –ed。

stop→stopped plan→planned prefer→preferred

5.不规则动词的过去式需特殊记忆。 Step 4 Project

1. Review the past simple tense. 2. Homework
