Unit1 Relationships语法讲解与练习
语法:过去完成时详细讲解
(一)核心定义:什么是过去完成时?
过去完成时表示在过去某一个动作/时间之前已经发生,完成的动作或存在的状态,通俗总结为:过去的过去。
关键前提:必须有一个过去的参照点(一般过去时动作/过去时间点),不能单独使用。
例句1:I had finished my homework before my parents came back.
(父母回来前,我就写完了作业)
例句2:By the time I got up, my sister had gone to school.
(我起床时,姐姐已经去上学了)
(二)完整基本结构(肯定/否定/疑问)
1. 肯定句:主语+ had +过去分词
例句1:She had learned basic communication skills before entering high school.
例句2:They had built a close friendship long ago.
2. 否定句:主语 + had not (hadn’t) + 过去分词
例句1:I hadn’t met him before he joined our class.
例句2:She hadn’t realised her mistake until her friend reminded her.
3. 一般疑问句:Had +主语+过去分词?
例句1:Had you known each other before the competition?
例句2:Had he finished the report when the teacher checked?
4. 特殊疑问句:特殊疑问词+ had +主语+过去分词?
例句1:What had you done before you moved here?
例句2:How long had they stayed friends before they parted?
(三)必考时间标志词(看到直接优先考虑过去完成时)
by the time + 过去句子/ before +过去动作/by +过去年份/时间 / until / already / yet / never / just
例句1:By the end of last term, we had mastered basic interpersonal skills.
例句2:He had never argued with his best friend before that incident.
(四)四大核心用法
用法1:先后两个过去动作,强调“先完成”的动作用过去完成时,后发生的用一般过去时
例句1:The rain had stopped when we went out for a walk.
例句2:She had prepared gifts before her friends arrived.
用法2:主句一般过去时,宾语从句动作发生在主句之前,从句用过去完成时
例句1:He said that he had made a new friend in the dorm.
例句2:I found that she had already left the classroom.
用法3:描述过去的经历、次数、持续状态(截止到过去某时间)
例句1:By 2022, he had lived in this community for 8 years.
例句2:She had tried many ways to fix their relationship before giving up.
用法4:虚拟语气高频(本单元拓展考点):hardly/scarcely…when… / no sooner…than…
固定句式:Hardly had +主语+过去分词+ when +一般过去时
例句1:Hardly had I sat down when the bell rang.
例句2:No sooner had they met than they began to chat warmly.
(五)重难点辨析
1. 一般过去时 VS 过去完成时
一般过去时:只陈述过去事实,无先后对比;
过去完成时:强调过去的过去,有明确先后顺序。
例句1(一般过去时):He left home.(单纯陈述他离开了家)
例句2(过去完成时):He had left home when I arrived.(我到之前,他就已经走了)
2. already/yet 用法区别
already 多用于肯定句,yet 多用于否定、疑问句,常搭配过去完成时。
例句1:She had already finished her group work.
例句2:I hadn’t heard of the story yet.
(六)解题秒杀口诀
有过去、找先后,先发生者用完成;
by the time/before 现,过去完成必出现;
主句过去从句先,从句时态往前推。
