爱华网知识点：
一：一般过去时由动词的过去式表示，动词be有was,were两个过去式，was用于第一、三人称单数，were用于其他情况。在构成否定及疑问句时，一般都借助助动词did,动词be有其独特的疑问及否定形式（基本上和一般现在时一致）。
二：这个时态的三种结构可表示如下：
1：否定式均由did not +动词原形构成
I / you / he / she/ they / we did not work.
2：疑问式均由 did + 主语 +动词原形 构成
三：在英语当中有一部分动词的过去式变化形式是不规则的，这类动词被称为不规则动词。总数大概不过200多个，但是使用频率很高。主要分成三类：
1、第一类不规则动词的三种形式同形，如：
cost costcost
cut cutcut
hurt hurthurt
shut shutshut
set setset
注意，有些动词的过去式与过去分词有两中形式，如：
bet bet / bettedbet / betted
wed wed / weddedwed / wedded
wet wet / wettedwet / wetted
2》第二类不规则动词的过去式和过去分词同形，如：
bend bentbent
bring broughtbrought
catch caughtcaught
hide hid hid /hidden
get got got/gotten(AmE)
lead ledled
3》第三类不规则动词的原形、过去式和过去分词都不相同，如：
原形过去式过去分词
begin beganbegun
break brokebroken
forbid forbadeforbidden
grow grewgrown
ring rangrung
wake woke / wakedwoken / waked
此外还有少数不规则动词的过去分词与原形相同，如：
