现在进行时专项练习

现在进行时专项练习在英语的时态体系中，现在进行时如同一个动态的镜头，捕捉着当下正在发生的动作与情景。掌握它，不仅能让我们精准描述眼前的景象，更能帮助我们理解动作的临时性与持续性。以下，我们将通过系统的梳理与针对性练习，深化对这一时态的理解与运用。一、定义与构成现在进行时，顾名思义，用于表示此时此刻正在进行或发生的动作，也可用于表示现阶段正在进行但说话瞬间不一定正在进行的动作，或是按计划、安排近期内即将发生的动作（多与表示移动的动词连用）。其构成方式为：主语+be动词(am/is/are)+动词的现在分词(-ing形式)*be动词的选择：根据主语的人称和数进行变化。第一人称单数用am，第三人称单数用is，第二人称单复数及第一、三人称复数用are。*现在分词的构成：*一般情况下，直接在动词词尾加-ing：work-working,eat-eating。*以不发音的字母e结尾的动词，去掉e再加-ing：write-writing,dance-dancing。*以重读闭音节结尾，且末尾只有一个辅音字母的动词，双写这个辅音字母再加-ing：run-running,sit-sitting,swim-swimming。*以ie结尾的动词，通常将ie改为y再加-ing：lie-lying,die-dying。二、核心用法解析1.表示此时此刻正在进行的动作：这是现在进行时最基本也最常见的用法，常与now,atthemoment,look,listen等词或短语连用，以强调动作的即时性。*Look!Thechildrenareplayinginthegarden.(看！孩子们正在花园里玩。)2.表示现阶段正在进行的动作：动作可能并非在说话的exact瞬间发生，但在当前一段时间内持续进行。常与thesedays,thisweek,recently等时间状语连用。*Sheislearningtoplaythepianothesedays.(这些天她在学弹钢琴。)*Weareworkingonanewprojectthismonth.(这个月我们正在做一个新项目。)*Myparentsarearrivingtomorrowmorning.(我父母明天早上到。)4.与always,constantly,forever等副词连用，表示反复发生的动作或持续存在的状态，往往带有说话人的某种情感色彩，如赞赏、厌烦、不满等。*Heisalwayshelpingothers.(他总是乐于助人。——赞赏)三、专项练习（一）基础填空：用所给动词的适当形式填空。1.Listen!Someone__________(sing)inthenextroom.2.Mybrother__________(notwatch)TVnow;he__________(do)hishomework.3.What__________you__________(do)atthemoment?5.Theworkers__________(build)anewbridgeovertheriverthesedays.6.Sheusually__________(read)novelsintheevening,buttonightshe__________(read)anewspaper.7.Theplane__________(takeoff)at6:00p.m.tomorrow.(提示：按计划)8.He__________(alwayslose)hiskeys.It'ssoannoying!（二）句型转换：按要求改写下列句子。1.Theyareplayingfootballinthepark.(改为否定句)_________________________________________________2.Sheiswritingaletter.(改为一般疑问句，并作肯定回答)_________________________________________________3.Iamcookingdinner.(对划线部分提问)_________________________________________________4.IsTomcleaninghisroomnow?(作否定回答)_________________________________________________5.Thebirdsaresinginginthetree.(对划线部分提问)_________________________________________________（三）情景对话补全：根据上下文，用现在进行时补全对话。A:Hello,thisisMikespeaking.B:HiMike,thisisLucy.What__________you__________(do)rightnow?A:I__________(watch)adocumentaryaboutwildlife.It'sreallyinteresting.Whataboutyou?B:I__________(notdo)much.I__________(fold)thelaundry.Bytheway,__________yoursister__________(study)forherexamtoday?A:Yes,she__________(sit)inherroomand__________(review)hernotes.She__________(work)veryhardthesedays.（四）段落填空：用括号内动词的适当形式完成短文。It'satypicalSundayafternoon.Thesun__________(shine)brightly,andagentlebreeze__________(blow).Inthepark,manypeople__________(enjoy)theirweekend.Somechildren__________(run)aroundand__________(laugh)loudly.Agroupofoldmen__________(play)chessunderabigtree.Ayoungcouple__________(walk)handinhandbythelake.Amother__________(push)herbabyinastroller,andthebaby__________(smile)happily.Everyone__________(seem)toberelaxedandhappy.四、答案与解析（一）基础填空1.issinging(listen提示此时此刻)2.isn'twatching,isdoing(now提示，前后动作对比)3.are,doing(atthemoment提示)5.arebuilding(thesedays提示现阶段)6.reads(usually提示一般现在时),isreading(tonight提示今晚正在进行)7.istakingoff(按计划发生)8.isalwayslosing(always与进行时连用，表示不满)（二）句型转换1.Theyarenot(aren't)playingfootballinthepark.2.Isshewritingaletter?Yes,sheis.3.Whatareyoudoing?(划线部分是cookingdinner，对动作提问用what)4.No,heisn't.5.Wherearethebirdssinging?(划线部分是inthetree，对地点提问用where)（三）情景对话补全B:are,doingA:amwatchingB:amnotdoing,amfolding,is,studyingA:issitting,reviewing,isworking（四）段落填空isshining,isblowing,areenjoying,arerunning,laughing,areplaying,arewalking,ispushing,issmiling,
