新概念英語第一冊自學導讀Lessons71-72語法Grammarinuse

一般過去時（2）

（請參見Lessons67～68語法局部。）

be動詞以外的動詞在一般過去時中一般有兩種形式。規(guī)章動詞一般是在動詞后面加-ed，如answered；以-e結尾的規(guī)章動詞加-d，如telephoned,arrived。另一局部動詞的過去式拼寫不規(guī)章，因此稱為不規(guī)章動詞，如：say----said,do----did。

用一般過去時的句子中經(jīng)常有表示過去某一時刻的時間狀語，如本課中的yesterday（昨天），thedaybeforeyesterday（前天），yesterdaymorning（昨天上午），yesterdayafternoon（昨天下午），yesterdayevening（昨天晚上），lastnight（昨夜）。
