第一类:肯定句变否定句
1(be动词类)在表示过去存在的状态的句子中在was, were的后面加上not。
肯定句:He was in the park the day before yesterday.
否定句:He was not in the park the day before yesterday.
2.(行为动词类)要在行为动词的前面加助动词didn’t. 然后把动词过去式改为动词原形。即:didn’t 动词原形
肯定句:She played the violin last night.
否定句:She didn’t play the violin last night.
第二类:一般疑问句
did 主语 行为动词原形
was / were 主语 其他成分
They finished their work at four.
一般疑问句,Did they finish their work at four?
Yes, they did. No, they didn't
第三类: 特殊疑问句
特殊疑问词 did 主语 行为动词原形
They finished their work at four.
如果对动词短语finished their work划线是What did they do at four?
如果对时间at four划线是When did they finish their work?
好了今天就和大家分析到这里了,最后再和大家强调一下,一般过去式是英语中的一个非常重要的语法点,大家一定要弄透了,才算你的语法是合格的,欢迎提出宝贵的意见。
