在时间状语从句中,主句和从句的动作是先后发生还是同时发生?主句和从句分别用了什么时态?引导词有哪些?
Read the sentences belw, and circle the cnjunctins f clauses and underline the tense.
By the time I gt back t schl, the bell had rung.
在过去某个时间或某个动作之前发生的动作或存在的状态,它表示动作发生的时间是“过去的过去”。
肯定句: 否定句:一般疑问句:
构成:___________________________
助动词had+动词的过去分词
主语+had+过去分词+其他.
主语+hadn’t(had nt)+过去分词+其他.
—Had+主语+过去分词+其他?—Yes, 主语+had./ N, 主语+hadn’t.
(1)表示某一动作或状态在过去某一时间或动作之前已经发生或完成,即发生在“过去的过去”。这个过去的时间常与by, befre等构成的短语连用。
例:我睡醒时我的父母已经开始工作了。 My parents had begun t wrk by the time I wke up.
(2)过去完成时用在tld, said, knew, heard, thught 等后面的宾语从句中。
例:约翰说它拥有这辆自行车五年了。 Jhn said he had had the bike fr five years.
根据句意,写出括号内所给单词的适当形式。Yu tld me yu had ______(deal) with these letters.Why are they still here?
(3)在含有时间、原因、方式等状语从句的复合句中,主、从句的动作都发生在过去,且有明显的先后关系,动作在前的要用过去完成时,动作在后的要用一般过去时。
例:迈克不想再吃鸡肉了,因为他已经吃够了。 Mike wanted n mre chicken because he had had enugh.
After he turned ff the light, he had left the rm. ( )After he turned ff the light, he left the rm. ( )
注意:在由befre, after 引导的时间状语从句的复合句中,由于befre和after 本身已表达了动作的先后关系,若主、从句表示的动作紧密相连,则主、从句都可用一般过去时。
(4)一般可根据上下文语境来确定过去完成时的时态。
例:尽管他失败了很多次,但他从没放弃过。 Althugh he had failed many times, he never gave up.
(1)由时间状语来判定 ① by+过去的时间点 例:到昨天9点钟时,她已经读完了这本书。 She had finished reading the bk by 9 ’clck yesterday.
② by the end f+过去的时间点 例:到上个月月底,我们已经完成了所有工作。 We had cmpleted all the wrk by the end f last mnth.
