外研社四年级上语法总结

一般过去时

一般过去时用来表示过去某一时间内发生的动作或存在的状态以及过去习惯性、反复性的动作。谓语动词要用动词的过去式，常和表示过去的时间状语连用，如yesterday昨天、last night昨晚、last week上周、last year 去年，等

时间状语：

1.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

Was，were的一般过去时

Be动词在一般过去时中的变化：

1．am和is在一般过去时中变为was。（was not=wasn’t）

2．are在一般过去时中变为were。（were not=weren’t）

3．带有was或were的句子，其否定、疑问的变化和am, is,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

构成：

肯定句式：主语+be(was,were)+其它.

否定句式：主语+be(was,were)+not+其它.

一般疑问句：Be(was,were)+主语+其它？

肯定回答: Yes, 主语+ be(was,were)

否定回答：No, 主语+be(was,were)+not.

含有实义动词（行为动词）的一般过去时的主结构：

构成：

肯定句：主语+动词的过去时+其它。

否定句：主语+did+not+动词原形+其它。did not缩写为didn’t
