考点4
by the end of 与表示时间的名词连用, 通常根据by the end of 之后时间的不同, 句子选用相应的时态:
(1) 接表示将来的时间, 句子用一般将来时。
e.g. By the end of next month, I will finish reading the book.
到下个月底, 我将读完这本书。
考向
(2) 接表示现在的时间, 句子用现在完成时。
e.g. By the end of this week, my sister has learned five English songs.
到这周末, 我妹妹学了五首英语歌曲。
(3) 接表示过去的时间, 句子用过去完成时。
e.g. By the end of last year, thousands of trees had been planted in this city. 到去年年底, 这个城市有成千上万棵树已被种植。
辨析:by the end of, at the end of 与in the end
by the end of “在……之前”, 仅指时间。
at the end of “在……结束时;在……尽头”, 指时间或地点。强调一段时间的结束点或某段路程的终止处。
in the end “最后;终于”, 位于句首或句末, 表示事情已结束。

概念:过去完成时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。也可以指过去的动作或状态延续到过去的某一时刻。它表示动作发生的时间是“过去的过去”。
考点1
过去完成时
构成:过去完成时由“助动词had (用于各种人称和数) +动词的过去分词”构成。
考点2
速记小法:
巧学过去完成时:
过去完成时态不算难,形式要向完成时态看。
have 变成had 不怠慢,断定过去之前是关键。
过去完成时的判断依据。
考点3
表示在过去某一时刻或动作之前已经发生或完成了的动作, 常和by, before 或by the end of 构成的介词短语及by the time 或until 引导的时间状语从句搭配。
考向1
考题1:[绥化] By the time the teacher came, we ______ cleaning the classroom.
A. finished B. have finished C. had finished
C
【点拨】用语法判定法解题。By the time 引导时间状语从句,从句为一般过去时,主句用过去完成时,表示截止到从句动作发生时,主句动作已经完成,即过去的过去。
表示从过去的某一时刻开始,一直持续到过去另一时间的动作或状态,常和for 或since 构成的时间状语连用。
e.g. I had studied English for three years before coming to this school.
在来这所学校之前,我已经学习英语三年了。
Tom said that he had worked in that factory since 2013.
汤姆说自从2013 年以来他就在那家工厂工作。
考向2
考题2:When we got to the cinema, the movie ______ for ten minutes.
A. has been on B. had been on
C. had begun D. began
【点拨】考查过去完成时及动词的延续性与非延续性。过去完成时表示在过去某一动作发生之前已经完成或发生了的动作。“电影开始”这一动作在“到达”这一动作之前发生,故用过去完成时。begin 为非延续性动词,与时间段搭配时常用be on。
B
过去完成时经常用于主句为一般过去时的宾语从句中, 表示从句动作先于主句动作发生, 像在told, said, knew, heard, thought 等动词后的宾语从句中。
考向3
考题3:[无锡] You told me you had ________ (deal) with these letters. Why are they still here
【点拨】用语法判定法解题。过去完成时的结构为“had+ 动词的过去分词”。分析题目可知deal 用过去分词形式。
dealt
【易错点】在表示过去某一动作或状态的句子中, 常出现与完成时态连用的词, 如:already, yet, since, for, ever, never 及表次数的词, 此时句子常用过去完成时。
e.g. I met Jim in the street yesterday. We hadn’t seen each other since he went to Beijing.
我昨天在街上碰见了吉姆。自从他去北京后, 我们彼此还没有见过面。
考向4
考题4:[ 济宁改编] Although he _______________ (fail) many times, he never gave up.
【点拨】用语法判定法解题。过去完成时表示在过去某一动作发生之前已经完成或发生了的动作。分析句意可知在“放弃”这个动作发生之前,“失败”这个动作已经发生。故用过去完成时。
had failed
过去完成时的句式结构。
考点4
肯定句 主语+had+ 过去分词+ 其他.
否定句 主语+hadn’t+ 过去分词+ 其他.
一般疑问句及答语 Had+ 主语+ 过去分词+ 其他?
肯定回答:Yes, 主语+had.
否定回答:No, 主语+hadn’t.
考题5:Her mother had already gone to work by the time she got up. (变为否定句)
Her mother _________ gone to work _________ by the time she got up.
【点拨】用语法判定法及词义辨析法解题。含有过去完成时的句子变否定句时要在had 后加not。already 用于肯定句,yet 用于疑问句或否定句。
hadn’t yet
【特别提醒】
(1) 句中有yesterday, last year, in 2019, two weeks ago 等明确表示过去的时间状语时, 常用一般过去时, 而不用过去完成时。
(2) 叙述过去连续发生的两件及两件以上的事情时, 虽然时间上有先后之别, 但仍用一般过去时。
考点5
(3) 在包含before, after, when, until, as soon as 等引导的时间状语从句的复合句中, 如果主句的动作和从句的动作紧接着发生, 则主从句均用一般过去时。
本节课主要学习了过去完成时态的意义和用法, 了解了中考对这类题的考查角度, 掌握了这类题的做题方法。
