一、语法知识—— 行为动词的一般过去时
1. 行为动词的一般过去时
形式
did
例 句
用法
过去发生的动作或存在的状态
——What did you have for breakfast this morning?
——I had two eggs and a bowl of
noodles.
说话时已不复存在的情况
I didn’t know I lost my pen.
描述过去发生的一连串动作
Just now Jim turned off the light, locked
the door and left.
时 间
状 语
yesterday, the day before yesterday, last night, at that time, just now,
......ago 等
2. 规则动词过去式的构成
①一般在动词词尾加-ed play — played clean — cleaned
②结尾是 e 的动词加-d dance — danced
③末尾只有一个辅音字母的重读闭音节词,先双写这个辅音字母,再加-ed
stop — stopped trip — tripped
④ 尾是“辅音字母+y”结尾的词,先变 y 为 i ,再加-ed
study — studied
3. 句法结构
(1)肯定形式 主语+动词过去式+其他
E.g. She often came to help us in those days.
(2)否定形式 在行为动词前加 didn't,同时还原行为动词
E.g. I didn't know you like coffee.
(3)一般疑问句 Did+主语+谓语动词原型+其他?
E.g. Did I do homework?
回答: Yes, I did. \ No, I didn’t.
【巧学妙记】 动词一般过去时,表示过去发生事。
句中谓语用过去式,过去时间作标记。否定句,很简单,主语之后 didn’t 添, 疑问构成也有法,主语前面 did 加, 还有一点不能忘,后面的动词要还原。
二、知识点小结
1. decide to do sth 决定做某事
E.g. She decided to live in London
