新概念英语第一册自学导读Lessons71-72语法Grammarinuse

一般过去时（2）

（请参见Lessons67～68语法局部。）

be动词以外的动词在一般过去时中一般有两种形式。规章动词一般是在动词后面加-ed，如answered；以-e结尾的规章动词加-d，如telephoned,arrived。另一局部动词的过去式拼写不规章，因此称为不规章动词，如：say----said,do----did。

用一般过去时的句子中经常有表示过去某一时刻的时间状语，如本课中的yesterday（昨天），thedaybeforeyesterday（前天），yesterdaymorning（昨天上午），yesterdayafternoon（昨天下午），yesterdayevening（昨天晚上），lastnight（昨夜）。
