初中英语新外研版七年级下册Unit 1 语法讲解练习（2025春）

七年级英语下册Unit1语法讲解练习一、一般过去时知识讲解1.用法：(1)一般过去时表示过去某个时间或时间段内发生的动作或存在的状态；常有表示过去的时间状语标志，如lastnight，threedaysago，in1900，before等。e.g.Ivisitedmyparentslastnight.Hegotupat7:30yesterday.(2)一般过去时也表示过去经常或反复发生的动作。e.g.Tomalwayswenttoschoolbybuslastyear.Iwasoftenlateforschoolbefore.2.时间状语（标志词8大类）：(1)“last（上一个）+表示时间的单数可数名词(day/month/week/year等)”，意为“上一……”；e.g.lastday昨天=yesterdaylastmonth上个月(2)“时间段+ago(以前)”，意为“多长时间以前”；e.g.twoweeksago五周前(3)“in+过去的年份”，意为“在哪一年”；e.g.in1918在1918年，这里要注意区分in+未来的年份，如in2099，这个就要用未来时(4)inthepast在过去；(5)then=atthatmoment在那时。(6)由when，as，though等引导的状语从句中，有时从句需用一般过去时。e.g.WhenTomcamebackyesterdaynight,hismotherwascookingdinner.Tomdidn’tcomebackhomeuntilIfinishedmyhomework.(7)since意为“自从”，引导的时间状语从句，从句用一般过去时，主句用现在完成时。e.g.TomhaslivedinKunmingsincehecamehere.MyparentshavebeenawayfrommyhometownsinceIwenttotheuniversity.(8)大多数情况下，由并列连词and，but和or连接的句子，前后时态需一致。如果其中一部分用了一般过去时，这些词连接的另一部分也需要用一般过去时。e.g.Tomwashardworking,buthewascareless.Ilikedapplesandmymotheralsolikedapplesinthepast.3.谓语动词形式：(1)be动词:was(am/is的过去时)；were(are的过去时)。①was：主语为单数（包括I）名词，代词，词组或是句子；was是am和is的过去式。②were：主语为复数名词，代词，词组或是句子；were是are的过去式。e.g.Iwasauniversitystudentthreeyearsago.Markisn’twhathewasinthepast.Theywerestrangers.(2)实义动词：过去式形式。注意：当谓语动词为实义动词的过去式式时，谓语动词的形式不受主语的影响。e.g.TomwenttoShanghailastsummerholiday.Myfatherusedtogoforawalkaftersupper.Everythingwentwellatthatmoment.4.一般过去时中肯定句转换为否定句，一般疑问句以及肯定和否定回答的知识点总结。4,(1)含有be动词（was/were）的陈述句转换为一般疑问句时，直接把be动词提到句首，然后把“.”转换为“?”即可，其中第一人称I，we和our要相应的转换为第二人称you和your。肯定及否定回答用相对应的be动词来回答即可，但是主语需转换为对应的人称代词（therebe句型除外，直接用there来回答）；若是肯定句转换为否定句，直接在be动词后面加not，可缩写，可全称；但否定回答只能用缩写。wasnot=wasn’t；werenot=weren’te.g.①肯定句:TomandMarywerefriendsbefore.否定句:TomandMarywerenot/weren’tfriendsbefore.一般疑问句:WereTomandMaryfriendsbefore?肯定回答:Yes,theywere.否定回答:No,theyweren’t.②肯定句:Theapplewasgood.否定句:Theapplewasnot/wasn’tgood.一般疑问句:Wastheapplegood?肯定回答:Yes,itwas.否定回答:No,itwasn’t.(2)含有实义动词的陈述句转换为一般疑问句时，需要请助动词did，然后把助动词提到句首，后面的实义动词必须转换为原形。肯定回答和否定回答也用相应的助动词来回答即可，但是主语需转换为对应的人称代词，注意否定回答必须用缩写。若是肯定句变为否定句，直接在助动词did后面加not变为否定形式，放于谓语动词之前，但切记请了助动词，后面的谓语动词必须变为原形。didnot=didn’te.g.①肯定句:Iwenttothezooyesterday.否定句:Ididnotgotothezooyesterday.一般疑问句:Didyougotothezooyesterday?肯定回答:Yes,Idid.否定回答:No,Ididn’t.②肯定句:Shevisitedherunclelastyear.否定句:Shedidn’tvisitherunclelastyear.一般疑问句:Didshevisitherunclelastyear?肯定回答:Yes,shedid.否定回答:No,shedidn’t.5.易混项非常需要注意的是，在实际的考题中，时态类考题通常会和固定搭配的短语、使动短语等一起考，来增加难度和区分孩子是否理解透彻。常考的易混点如下：1.makesb+形容词使某人…+名词使某人成为.…dosth使某人做某事2.keepdoingsth继续做某事，一直做某事3.decide/choose/want/remembertodosth决定/选择/想要/记得做某事4.letsbdosth让某人做某事5.likedoingsth喜欢做某事6.havetodosth必须做某事7.howtodosth如何做某事whattodo做什么8.Whatdoyoumeanby...?你……是什么意思?9.It'stimetodosth.到做某事的时间了。4,10.What'ssthlike?某物是什么样子的?11.Itis+形容词+todosth.做某事是……的。二、过去时态练习1.Lastweekend,myparents______(make)mefeellovedbycookingmyfavoritemeal.2.She______(keep)helpingherlittlebrotherwithhomeworkuntilhe______(understand).3.Itwasheartwarming______(see)thefamilyreunionphotoalbumyesterday.4.WhenI______(be)achild,mygrandmother______(tell)mestoriesaboutkindness.5.They______(make)thehousecozyby______(decorate)itwithflowers.6.Theboy______(keep)smilingwhenhe______(receive)abirthdaygiftfromhisdad.7.Itwasspecial______(celebrate)mysister’sgraduationtogetherlastmonth.8.WhileMom______(wash)dishes,Dad______(play)theguitarinthelivingroom.9.Mybrother______(break)thevaseaccidentally,buthe______(apologize)sincerely.10.We______(notexpect)thesurpriseparty,sowe______(feel)extremelyhappy.11.Theteacher______(make)theclassexcitedby______(announce)afieldtrip.12.They______(keep)dancingatthefamilyweddinguntilmidnight.13.Itwaschallenging______(learn)torideabike,butmydad______(teach)mepatiently.14.WhenI______(walk)home,I______(meet)anoldfriendfromprimaryschool.15.Mygrandparents______(visit)uslastsummer,andwe______(share)manyhappymemories.16.Thelittlegirl______(make)hermotheracardthat______(say),"Iloveyou."17.He______(keep)practicingthepianobecausehe______(want)tomakehisfamilyproud.18.Itwasunforgettable______(travel)tothecountrysidewithmycousinslastyear.19.Whileshe______(read)abook,hercat______(jump)ontoherlap.20.Thefamily______(laugh)togetherwhenthey______(watch)afunnymovie.21.She______(make)herfriend’sdaybetterby______(give)herahandmadegift.22.They______(keep)plantingflowersinthegardenuntilit______(start)raining.23.Itwasrelaxing______(sit)bythefireplacewithmyparentslastwinter.24.Whenthebell______(ring),allthestudents______(rush)outoftheclassroom.25.Myaunt______(bake)acake,andthesweetsmell______(fill)thewholekitchen.26.Thechildren______(make)apromisetoalways______(help)eachother.27.He______(keep)callinghisgrandparentsbecausehe______(miss)them.28.Itwastouching______(hear)howthecommunity______(support)thefamilyinneed.29.WhileDad______(fix)thecar,Mom______(prepare)lunchinthekitchen.30.Theoldphoto______(make)merememberhowwe______(hug)eachotheratthefarewellparty.【答案】1.made2.kept,understood3.tosee4.was,told5.made,decorating4,6.kept,received7.tocelebrate8.waswashing,played9.broke,apologized10.didnotexpect,felt11.made,announcing12.kept13.tolearn,taught
