一般過(guò)去時(shí)（2）

（請(qǐng)參見Lessons67～68語(yǔ)法局部。）

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

用一般過(guò)去時(shí)的句子中經(jīng)常有表示過(guò)去某一時(shí)刻的時(shí)間狀語(yǔ)，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）。
