初中英语过去进行时知识点整理

xx过去进行时知识点整理 一、xx过去进行时知识点解析: 对于过去进行时的考查,多以单选、词语运用或完形填空的形式考查学生在具体语境中灵活运用时态的能力。在考试中,会让大家判断是否该用过去进行时。 典型例题1:MARYADRESSWHENSHECUTHERFINGER. A.MADE B.ISMAKING C.WASMAKING D.MAKES 解析:割伤手指是已发生的事情,应用过去时。同时,WHEN表时间的同时性,表示“割伤手指”的时候“玛丽做衣服”的动作正在进行,它提供事情发生的背景,因此用过去进行时。 二、xx过去进行时知识点误区提醒: 过去进行时与一般过去时的区分,可能是同学们头疼的地方。大家可以记住以下四条; 1、一般过去时往往表示某一动作已经完成,而过去进行时却表示动作在持续或未完成。(延续性动词) SHEWROTEALETTERTOHERFRIENDLASTNIGHT.她昨晚给朋友写了封信。 (信写完了) SHEWASWRITINGALETTERTOHERFRIENDLASTNIGHT.她昨晚一直在给朋友写信。(信不一定写完) 2、一般过去时表示只做一次动作,而过去进行时却表示动作反复地进行。 (短暂性动词) SHEWAVEDTOME.她朝我挥了挥手。 3、句中有AMOMENTAGO之类的笼统的时间短语一般用一般过去时。

4、句中有ATTHISTIMELASTSUNDAY,FROM8TO9YESTERDAY之类的具体的时间状语一般用过去进行时。 典型例题:I______(WRITE)ALETTERATTENLASTNIGHT. 解析:所给的时间状语ATTENLASTNIGH“昨天晚上十点钟”是具体的过去的某一时刻,所以应该用过去进行时。 答案:WASWRITING 三、xx过去进行时知识点结构: 过去进行时的结构及句型变化 过去进行时由"WAS/WERE+现在分词"构成。如: IWASDOINGMYLESSONSTHEN.那时,我在做功课。WEWERECLEANINGTHEHOUSE.我们在打扫房子。 过去将来时态的肯定句、否定句和疑问句形式: 肯定句例句:IWASWALKINGDOWNTHESTREETWHENAUFOLANDED.否定句例句: IWASN’TWALKINGDOWNTHESTREETWHENAUFOLANDED. 一般疑问句例句: WEREYOUWALKINGDOWNTHESTREETWHENAUFOLANDED? 特殊疑问句例句:WHATWEREYOUDOINGWHENAUFOLANDED?
