(改变谓语动词) He has been back since three days ago. (改变谓语动词) He came back three days ago. (改变时间状语及动词时态) It’s three days since he came back. (改变句型) 注意： 在表示持续一段时间的句子中，应将短暂性动词转化为相同意义的延续性动词或状态动词。 短暂性动词 延续性动词 fall ill (asleep) finish, end begin, start go out get up borrow get to know die lose be ill (asleep) be over be on be out be up keep know be dead be lost 五 标志词（时间状语） Next 考点大观 易错辨析 通关训练 六 练习 词语正确形式填空 They ______________ their homework.
