新人教目标版八年级上册英语课时练习课件-Unit 2 How often do you exercise Section A（Grammar Focus-3c）

第三课时SectionA(GrammarFocus3c),单元同步语法精讲,表示频率程度的副词称为频度副词。eg：always，usually，often，sometimes，seldom和never等。这些词表示经常性的动作或状态，而不是某一具体动作，常用于一般现在时中。1频度的区别,2它们在句中的位置：频率副词在句中常位于be动词、助动词、情态动词之后，实义动词之前。sometimes有时可位于句首或句末。3表示频率的短语有：once/twiceaweek，threetimesaday，everyweek/year等。4对频率副词或短语提问用howoften。5频率副词或短语常与一般现在时态连用。eg：Inevereatmeat.我从不吃肉。Jimusuallydoeshishomeworkintheevening.吉姆通常晚上做作业。SallydoesntoftenwatchTVattheweekend.萨利周末不常看电视。Howoftendoyoueatfruit？你多久吃一次水果？,单元同步语法强化训练,一、单项选择。1Ifmyfriendshaveanyproblems，mydooris_opentothem.(2014，安徽)AneverBseldomCsometimesDalways2Didyougotothecinemalastnight?Oh，no.I_gotothecinema.Thetickets，youknow，aretooexpensive.(2014，宁波)AalwaysBhardlyCusuallyDoften3Mysister_goestobedearlybecausesheneedsalotofsleepeveryday.(2014，南昌)AalwaysBsometimesChardlyDnever,D,B,A,4LiKe_runsinthemorning，forhewantstobehealthy.(2014，成都)AneverBoftenChardly5Howoftendoyougoskating?_.Icantskateatall.(2014，温州)AAlwaysBSometimesCSeldomDNever6Whereshallweeattonight？(2014，河南)LetscallHarry.He_knowsthebestplacestogo.AonlyBnearlyCneverDalways7I_watchthisTVprogram.Itsveryinteresting.(2013，徐州)AoftenBneverChardlyDseldom,B,D,D,A,8_doyougotothesportsclub?Atleastonceaweek.(2014，苏州)AHowlongBHowoftenCHowmuchDHowfar9LookattheflowersIgaveyoulastmonth.Theyaredying！_doyouwaterthem?Sorry，Iforgottowaterthem.(2014，菏泽)AHowlongBHowoftenCHowsoonDHowmuch,B,B,二、按要求改写句子。10Theboydrinksmilkonce_a_day(对画线部分提问)_theboy_milk?11Shesleepsseven_hourseveryday.(对画线部分提问)_doesshesleepeveryday?12SheusuallywatchesTVintheevening.(变为一般疑问句)_she_TVintheevening?13Jeanishavingmilkandbreadforbreakfastnow.(用sometimes改写句子)Jean_milkandbreadforbreakfast.14Alicealwaysdoesherhomeworkat7pm.(变为否定句)Alice_herhomewo
