新概念英语第一册Lesson 77-78 练习题

各位同学，大家好！今天我们将针对《新概念英语第一册》Lesson77和78课的核心语法点进行梳理与练习。这两课的重点在于巩固一般过去时和过去进行时的用法，并理解它们之间的区别与联系。扎实掌握这两种时态，对于我们描述过去发生的事情至关重要。下面，让我们通过一系列有针对性的练习来深化理解。一、核心知识点回顾在开始练习之前，请大家快速回顾以下关键语法点：1.一般过去时(SimplePastTense)*构成:主语+动词的过去式(V-ed或不规则变化)。*用法:表示过去某个特定时间发生的动作或存在的状态，动作通常已完成。*时间状语:yesterday,lastweek,twodaysago,in2020,justnow等。2.过去进行时(PastContinuousTense)*构成:主语+was/were+动词的现在分词(V-ing)。*用法:表示过去某个特定时间点或时间段正在进行的动作。*时间状语:at8o'clocklastnight,thistimeyesterday,when/while引导的时间状语从句等。3.一般过去时与过去进行时的区别:*一般过去时强调动作的完成性和结果。*过去进行时强调动作在过去某一时刻的持续性和未完成性。*常搭配使用：when(引导短暂动作，用一般过去时)+while(引导持续动作，用过去进行时)。二、练习题Exercise1:Fillintheblankswiththecorrectformoftheverbsinbrackets.(用括号内动词的正确形式填空。)1.I_______(watch)TVat9p.m.lastnight.2.She_______(visit)hergrandparentslastSunday.4.Myfather_______(read)anewspaperwhilemymother_______(cook)dinner.(read;cook)5.Tom_______(notdo)hishomeworkyesterdayevening.He_______(go)tothecinema.(notdo;go)6._______you_______(see)Maryatthepartylastnight?(see)7.Thephone_______(ring)whenI_______(take)ashower.(ring;take)8.We_______(have)agoodtimeatthebeachlastsummer.Exercise2:Rewritethefollowingsentencesasrequired.(按要求改写下列句子。)1.Hewasreadingabook.(改为否定句)He______________readingabook.2.Theyplayedbasketballyesterday.(改为一般疑问句)_______they_______basketballyesterday?3.Iwaslisteningtomusicat7o'clockthismorning.(对划线部分提问)______________you_______at7o'clockthismorning?4.Sheboughtanewdresslastweek.(对划线部分提问)______________she_______lastweek?5.Weretheydancingwhenyouarrived?(作肯定回答)_______,they_______.Exercise3:Choosethebestanswer.(选择最佳答案。)1.Mybrother_______hisbikewhenhe_______off.A.rode;fellB.wasriding;fellC.rode;wasfallingD.wasriding;wasfalling2.I_______TVwhenthedoorbell_______.A.watched;rangB.waswatching;rangC.watched;wasringingD.waswatching;wasringing3.What_______you_______thistimeyesterday?A.do;doB.did;doC.were;doingD.are;doing4.He_______toLondonlastmonth.A.goB.goesC.wentD.wasgoing5.Whilemysister_______,I_______myhomework.A.sang;didB.sang;wasdoingC.wassinging;didD.wassinging;wasdoingA:Hi,Peter!What_______you_______(do)at8o'clocklastnight?Icalledyoubutnooneanswered.B:Oh,hi,Linda.I_______(have)dinnerwithmyfamilyatarestaurant.A:_______you_______(enjoy)themeal?B:Yes,verymuch.Thefood_______(be)delicious.Whataboutyou?What_______you_______(do)then?A:I_______(study)formyEnglishtest.Bytheway,_______Tom_______(go)totheconcertwithyou?Ithoughthelikesthatband.B:No,he_______(notgo).He_______(work)overtimeattheoffice.Exercise5:TranslatethefollowingsentencesintoEnglish.(将下列句子翻译成英语。)1.昨天这个时候，我正在公园里散步。2.他昨晚没有看电视，他读了一本小说。3.当老师进来的时候，学生们正在说话。4.你上周末去哪里了？5.我做饭的时候，电话响了。三、参考答案与解析Exercise1:1.waswatching(过去进行时，表示过去特定时间点正在进行的动作)2.visited(一般过去时，表示过去某个时间发生的动作)3.wereplaying,started(过去进行时+when+一般过去时，表示一个动作正在进行时，另一个动作突然发生)4.wasreading,wascooking(while连接两个同时进行的持续性动作，都用过去进行时)5.didn'tdo,went(一般过去时的否定式；第二个空仍为一般过去时)6.Did,see(一般过去时的一般疑问句)7.rang,wastaking(when引导短暂动作，用一般过去时；主句用过去进行时)8.had(一般过去时，表示过去的经历)Exercise2:1.wasnot/wasn't2.Did,play3.Whatwere,doing(对动作内容提问，用what...do)4.Whatdid,buy(对具体事物提问，用what)5.Yes,wereExercise3:1.B(while/when一个动作进行，另一个动作发生)2.B(同上)3.C(thistimeyesterday是过去进行时的标志)4.C(lastmonth是一般过去时的标志)5.D(while连接两个同时进行的动作)Exercise4:A:Hi,Peter!Whatwereyoudoingat8o'clocklastnight?Icalledyoubutnooneanswered.B:Oh,hi,Linda.Iwashavingdinnerwithmyfamilyatarestaurant.A:Didyouenjoythemeal?B:Yes,verymuch.Thefoodwasdelicious.Whataboutyou?Whatwereyoudoingthen?A:IwasstudyingformyEnglishtest.Bytheway,DidTomgototheconcertwithyou?Ithoughthelikesthatband.B:No,hedidn'tgo.Hewasworkingovertimeattheoffice.Exercise5:1.Iwaswalkingintheparkatthistimeyesterday.2.Hedidn'twatchTVlastnight.Hereadanovel./HereadanovelinsteadofwatchingTVlastnight.3.Thestudentsweretalkingwhentheteachercamein.4.Wheredidyougolastweekend?5.ThetelephonerangwhenIwascooking./WhileIwascooking,thetelephonerang.四、总结与学习建议做完以上练习，相信大家对一般过去时和过去进行时的理解又加深了一层。请务必注意：*语境是关键：判断
