初二年级下册英语知识点整理

初二年级下册英语知识点整理初二年级下册英语知识点整理 Unit3WhatwereyoudoingwhentheUFOarrived? 知识点：过去进行时 a)过去进行时由“was/were+动词ing形式”构成。以动词work 为列，b)其肯定式，c)否定式，d)疑问式以及简略答语见下表：肯定式：I/He/She/Itwasworking.We/You/Theywereworking. 否定式： I/He/She/Itwasnotworking.We/You/Theywerenotworking. 疑问式和简略答语：WasIworking?Yes,youwere. Washeworking?No,hewasn’t. 【注意】wasnot常简略为wasn’t;werenot常简略为weren’t e)过去进行时的用法：过去进行时表示过去某一时刻或某一段时间正在进行的动作。这一特定的过去时间，f)除有上，g)下文暗示以外，h)一般用时间状语来表示 not…until直到…才。表示动作在某时之前尚未开始，直到此时动作才开始。not…until可以用after或when来代替，但主句谓语动词要用肯定形式。Until为连词时后接时间状语从句，until 作介词时，后面接表示时间的名词。Until用于肯定句多表示动作或状态一直延续到until所表示的时间为止，意思为“直到…”from..till…中till往往表示不太具体的时间。From…to…或from…until常用来表示具体的'时间。

findit…todo，it在此句中为形式宾语代表动词不定式，动词不定式为真正的宾语，常用于这种用法的动词有 find,feel,think,make等。 “疑问词+不定式“结构相当于一个名词性从句，常常可用同等成分的从句代替。改写时，只需在疑问词后面加一个适当的主语(这个主语一般与主句的主语一致)，并将不定式改成适当形式的谓语即可。如， Wheretogoisstillaquestion.=Whereweshouldgoisstillaquestion. when与while:when连接的状语从句是个特殊句型，“前一个分句(谓语动词用过去进行时)+when(作并列连词，意思为“这时，突然”)+后一个分句(谓语动词用一般过去时)”表示在前一个动作正在进行的过程中突然发生了后一个动作，when强调动作的突然性，when后面的动词为非延续性动词;while表示“在….过程中”，强调在一段时间内，所以while引导的从句中的谓语动词必须为延续性动词。在状语从句中，若从句放在句首时，应用逗号与主句隔开。感叹句的构成：What+a/an+形容词+单数名词+主语+谓语!Whatagoodbookitis! What+形容词+复数可数名词+主语+谓语!Whateasyquestionstheyare! What+形容词+不可数名词+主语+谓语!Whatcoldweatheritis! How+形容词+主语+be动词!Hownicethewatchis! How+副词+主语+谓语!Howhardtheyareworking! 8.takeplace,happen“发生”：takeplace指“发生事先计划或预想到的事物”;happen指“一切客观事情或情况的偶然或未能预见地发生”。两者都是不及物动词或短语，后面不能跟宾语，也不能用于被动语态;happen的意义很广泛，而takeplace仅用于历史上的事件，集会等，是先行布置而后发生或举行的事件，它不用于地震等自然界的现象。 happentodo巧遇sthhappenstosb某人遭遇某事
