Ⅲ. 语法重点 学习not … until / till和复习句子的省略。特别要真正掌握not until型的强调表达和倒装表达。 【指点迷津】 not…until ( till ) 的四种句型 如果主句谓语动词是持续性动词,则主句常用肯定式,表示“直到……为止”,即:主句 ( 用肯定式 ) + until ( till ) 时间状语或状语从句。例如: I worked until ( till ) he came back . 我工作到他回来为止。 I watched TV until ( till ) 10 o\clock . 我看电视一直到10点钟。 如果主句的谓语动词是瞬间动词,则主句必须用否定式,译为“直到……才”,即:主句 ( 用否定式 ) + until ( till ) 时间状语或状语从句。例如: I didn\t go to bed until ( till ) he came back . 直到他回来我才睡觉。 I didn\t go to bed until ( till ) 10 o\clock last night . 昨晚我直到10点钟才睡觉。 注意:用在句首时,一般只用 until 而不能用 till。例如: Until I finished my homework , I didn\t go to bed . 直到做完家庭作业我才睡觉。 Not + until 时间状语或状语从句 + 助动词 ( 常用 did ) + 主语 + 动词原形 ( 注:not 放在句首,故用部分倒装 ) 译为:“直到……才”。可以简化成:Not until…did + 主语。例如: Not until I finished my homework did I go to bed last night . I didn\t go to bed until ( till ) 10 o\clock last night . 昨晚我直到10点钟才睡觉。 注意:用在句首时,一般只用 until 而不能用 till。例如: Until I finished my homework , I didn\t go to bed . 直到做完家庭作业我才睡觉。 Not + until 时间状语或状语从句 + 助动词 ( 常用 did ) + 主语 + 动词原形 ( 注:not 放在句首,故用部分倒装 ) 译为:“直到……才”。可以简化成:Not until…did + 主语。 Not until I finished my homework did I go to bed last night . 昨晚直到做完家庭作业我才睡觉。 Not until last week did he realize he was wrong . 直到上星期他才认识到他是错误的。 It was not + until 时间状语或状语从句 + that + 主句 ( 注:此句型实际上是强调 not until 状语或状语从句。同学们应该记住:无论是强调时间、地点或原因状语,一般只用 that。这一点与定语从句不同,且此句型是陈述句语序,不用倒装。 ) 可以简化成句型:It was not until… + that . 例如: It was not until I finished my homework that I went to bed . 是在做完作业之后我才去睡觉的。 It was not until last week that he realized he was wrong . 一直到上个星期他才认识到他是错误的。 【针对练习】 1 .
