譯林版三下（新版）Unit34語法講練測【核心語法】一、祈使句的否定與肯定形式知識點： 1.否定祈使句：1)Don't+動詞原形（或be動詞）+其他成分行為動詞開頭：這類句式多用于禁止具體動作。例句：Don'ttouchthewetpaint.（別碰未干的油漆。）Don'tforgettoturnoffthelights.（別忘了關(guān)燈。）be動詞開頭：此類句式常用于表達對狀態(tài)或態(tài)度的禁止，例如提醒他人避免某種持續(xù)性行為。例句：Don'tbenoisyinthelibrary.（不要在圖書館喧嘩。）Don'tbeafraidofmakingmistakes.（不要害怕犯錯。）Let+賓語+not+動詞原形這是在動詞原形前加“not”構(gòu)成的否定句，語氣較委婉。例句：Lethimnotein.（別讓他進來。）Letthechildrennotjumponthebus.（別讓孩子們在汽車上跳躍。）祈使句的否定形式還有一種常見的是“No+名詞/動詞ing形式”，這類祈使句一般表示禁止或規(guī)勸的含義，用于警示人們不許做某事。例如：“NoParking.”（禁止停車。）或“Nosmoking.”（禁止吸煙。）2.肯定祈使句：結(jié)構(gòu)：動詞原形開頭（例：Closethedoor.）或Let’s+動詞原形（例：Let’sfollowtherules.）易錯點：在Let’s后加to（如錯誤句子Let’stoplay.）練習題：1.______eatinthelibrary.(Don’t/Not)2.改錯：Norunintheclassroom!_____________________________________3.連詞成句：your/desk/draw/on/don’t/._____________________________________翻譯：請保持安靜！_____________________________________5.—Let’splayhideandseek!—______(Goodidea!/No,thanks.)6.______(Don’t/Not)lookoutofthewindow.7.改錯：Let’snottoshoutinclass._____________________________________8.—______talkinthelibrary.—OK.A.Don’tB.NotC.No9.翻譯：不要在課桌上畫畫。_____________________________________10.連詞成句：follow/rules/let’s/the/._____________________________________二、方位介詞知識點：1.常見介詞：behind（在……后），by（在……旁），under（在……下），on（在……上），infrontof（在……前）2.易錯點：1)混淆by與near（by表示緊挨，near表示附近）2)錯誤使用inthetree（外來物）與onthetree（樹上生長的）練習題：1.Thecatis______(under/on)thechair.2.改錯：Thebookisinfrontthedesk._____________________________________3.連詞成句：butterfly/the/by/tree/is/the/._____________________________________4.翻譯：我的飛機在花叢中。_____________________________________5.選擇：—Whereistheruler?—It’s______thedesk.A.byB.onC.under6.填空：Theballis______(在……后面)thedoor.7.改錯：Theapplesareinthetree.(假設(shè)蘋果是長在樹上的)_____________________________________8.翻譯：不要站在黑板前面。_____________________________________9.連詞成句：flowers/the/in/plane/is/the/._____________________________________三、特殊疑問句Where的用法知識點：1.句型結(jié)構(gòu)：Whereis/are+主語?→回答用方位介詞短語（例：Whereismypen?It’sunderthebook.）2.易錯點：混淆Whereis（單數(shù)）與Whereare（復數(shù)）（如錯誤句子Whereisthepencils?）練習題：1.—______arethecrayons?—They’reinthebox.2.改錯：Whereisyourbooks?_____________________________________3.連詞成句：the/where/butterfly/is/?_____________________________________4.翻譯：你的書包在哪里？_____________________________________5.填空：—Where______(is/are)thestudents?—They’reintheplayground.6.選擇：—______isthecat?—It’sbehindthedoor.A.WhatB.WhereC.How7.翻譯：我們的美術(shù)社團在花園旁邊。_____________________________________8.連詞成句：plane/my/where/is/?_____________________________________9.改錯：Wherearethepencil?_____________________________________四、情態(tài)動詞can的否定與疑問知識點：1.否定句：can’t+動詞原形（例：Wecan’teathere.）2.疑問句：Canyou...?→回答Yes,Ican./No,Ican’t.3.易錯點：在can后加動詞不定式（如錯誤句子Icantoread.）練習題：1.—______youplayoutside?—Yes,Ican.2.改錯：Shecan’tdrawsonthedesk._____________________________________3.翻譯：我們不能在圖書館跑步。_____________________________________4.連詞成句：the/clean/can/blackboard/you/?_____________________________________5.填空：I______(can/can’t)findmyruler.It’slost.6.選擇：—Canweeatinclass?—______A.Yes,wecan.B.No,wecan’t.7.翻譯：你會畫蝴蝶嗎？_____________________________________8.改錯：Canhetoclosethewindow?_____________________________________9.連詞成句：run/don’t/can’t/we/here/._____________________________________10.選擇：—______canyousee?—Abeautifulflower.A.WhatB.WhereC.How【考點精煉】一、單項選擇（共10題）（）1.—Don’t______inthelibrary.—OK.A.runB.runningC.runs（）2.Thecatis______thetable.A.behindB.inC.between（）3.—______isyourpencilcase?—It’sonthedesk.A.WhatB.WhereC.How（）4.—CanIeathere?—No,you______.A.canB.can’tC.don’t（）5.—Let’splayfootball!—______!A.GoodideaB.No,thankyouC.Don’trun（）6.—Where______mycrayons?—They’reinthebox.A.isB.amC.are（）7.—______shoutinclass!—Sorry,MissLi.A.Don’tB.NotC.No（）8.Theapplesare______thetree.A.inB.onC.under（）9.—What’s______thechair?—It’saball.A.behindB.byC.for（）10.—______yourbrotherlikeswimming?—Yes,hedoes.A.DoB.DoesC.Is二、填空題（共10空）1.Don’t______(draw)onthedesk.2.Thebutterflyis______(在……旁邊)theflowers.3.—Where______(be)therobots?—They’reunderthechair.4.Wecan’t______(eat)inthelibrary.5.Let’s______(follow)theschoolrules.6.Myschoolbagis______(在……下面)thetable.7.—______(不要跑)intheclassroom!8.Thebirdis______(在……里)thetreenow.9.—Canyou______(clean)theblackboard?—Yes,Ican.10.—Whereisthelunchbox?—It’s______(在那里).三、連詞成句（共5題）1.don’t/the/draw/desk/on/.____________________________________2.is/where/the/butterfly/?____________________________________3.can’t/we/here/run/.____________________________________4.your/is/schoolbag/where/?____________________________________5.let’s/outside/play/.____________________________________四、閱讀理解（共2篇，每篇5題）A.SchoolRulesHello!I’mLucy.Ourschoolhasmanyrules.Don’trunintheclassroom.Don’teatinthelibrary.Keepquietinclass.Wecanplaygamesafterschool.Let’sfollowtherules!根據(jù)短文判斷正誤（T/F）：1.()Wecanrunintheclassroom.2.()Don’teatinthelibrary.3.()Wemustshoutinclass.4.()Wecanplaygamesafterschool.5.()Lucylikesschoolrules.B.FunAfterClassTodayisFriday.Afterclass,TimandAmyplayhideandseek.Timhidesbehindthedoor.Amyhidesunderthetable.“Whereareyou?”Timasks.“I’mhere!”saysAmy.Theyareveryhappy.根據(jù)短文選擇正確答案：（）1.Whatdayistoday?A.MondayB.FridayC.
