四年级下册一般现在时

教师：学生：学段：四学科：英语第次-1-一般现在时一般现在时的用法(1)表示经常发生或习惯性发生的动作时，用一般现在时态。如：IoftenwatchTVathome.(2)表示客观的事实，用一般现在时态。如：Therearesevendaysinaweek.一般现在时的构成当句子主语是I,we,they,you或复数名词时，动词用动词原形。当句子的主语是he,she,it或单数名词时，动词要用第三人称单数的现在式形态。具体讲解：特别注意特征词(oftenusuallyalwayssometimesneverseldomevery+时间)在句子中的标志作用，在做练习时最好把他们标记出来。例子：Sheusuallydoesherhomeworkafterdinner.注意区分好人称，第一，二人称和第三人称复数只需要用动词原形，他们的否定形式是“don’t+动词原形”，他们的疑问形式为“Do…+动词原形…?”如果是第三人称单数就要作动词的变化。例子：Theygotoworkbybusonweekdays.Theydon’tgotoworkbybusonweekdays.Dotheygotoworkbybusonweekdays?对于句子中的“doesn’t+动词原形”及“Do…+动词原形…?”分别是否定和一般疑问句的形式，一旦遇见“doesn’t”“do”这两个词时，动词必须还原。Thegirllikeseatingfruitsverymuch.Thegirldoesn’tlikeeatingfruitsatall.Doesthegirllikeeatingfruits?1.标识词，特征词：oftenusuallyalwayssometimesneverseldomevery+时间2.构成：主语是一(I/we).二人称(you)及复数形式(they)：人/物+动词原形例子：I/Weoftengotoschoolontimeeveryday.否定形式：…don’t+动词原形例子：I/Wedon’toftengotoschoolontimeeveryday.教师：学生：学段：四学科：英语第次-2-提问：Do…+动词原形…?Yes,…do.No,…don’t.例子：Doyouoftengoschoolontimeeveryday?Yes,Ido.No,Idon’t.第三人称单数（he/she/it以及一个人/物）：人/物+动词未尾+“s”或“es”例子：a.He/Sheusuallygoestoschoolbycareveryday.b.Janet/Benhaslunchat12:00everyday.c.Thecateatsafisheveryday.3.动词的变化：动词末尾+“s”或“es”（1）一般情况下，在动词后面+s，如：look---lookseat---eats（2）以“s”，“x”“sh”“ch”“o”结尾的单词在词尾+“es”，如：watch---watcheswash---washescatch---catchesteach---teaches（3）以辅音字母+“y”结尾的单词，把“y”改为“i”再+“es”,如：fly---fliescarry---carriestry---tries（4）特殊形式：have---has4.否定形式：…doesn’t+动词原形例子：Theoldmanplayschessinthemorning.Theoldmandoesn’tplaychessinthemorning.5．提问：Does…+动词原形…?Yes,…does.No,…doesn’t.例子：Doestheoldmanplaychessinthemorning?Yes,hedoes.No,hedoesn’t.巩固练习选择正确的答案填空，将其字母编号写在题前的括号内。（）1.Mymother_______houseworkeveryday.A.didB.doC.does（）2.Theliondoesn’t______thenetthreetimesaday.A.bitedB.biteC.biting（）3.He______abigholeeveryweek.A.makesB.ismakingC.made（）4.Doesthecat______amouseeveryhour?教师：学生：学段：四学科：英语第次-3-A.catchB.catchingC.catches（）5.Heusually_______theearthtothehill.A.carryB.carriesC.carrys（）6.Mymotheralways_______upathalfsix.A.gotB.getC.gets（）7.Sheoften_____underabigtreeand_____booksinthemorning.A.sit…readsB.sits…readC.sits…reads（）8.______theboy______TVonweekdays?A.Do…watchesB.Does…watchC.Do…watch（）9.Theirfriend______totheparkeverytwodays.A.goB.goesC.going（）10.Henever______alotofwaterafterhe_____football.A.drinks…playB.drinks…playsC.drink…plays（）11.____yourmother_____acartogetthereeveryday?A.Does…driveB.Do…driveC.Do…drives（）12.Heseldom______anything.A.forgetB.forgotC.forgets（）13.Sheoften______overwhenshe______thebaton.A.falls…getsB.falls…getC.fall…gets（）14.Janet______thedogeverymorning.A.feedB.feedingC.feeds（）15.Myfather_______wellintheeveningeveryday.A.doesn’tfeelB.don’tfeelC.doesn’tfeels（二.在下面的动词后加-s或-es.(1)catch_________(2)go_________(3)cost_________(4)fish________(5)listen_________(6)do____________(7)fall________(8)show__________(9)brush__________（三.翻译。1．Ioften____________________(看电视)intheevening.2．Jack____________________(踢足球)everyafternoon.3．Jane______________(购物)withhermotherontheweekend.教师：学生：学段：四学科：英语第次-4-4．Theyall__________(喜欢)Englishteacher.5．Jackoften__________(睡觉)atten.6．Dothey____________________(吃晚饭)athome?7．Weoften__________(跳舞)inmusicclass.8．Achair__________(有)fourlegs.（四）.用适当的动词形式填空.(1)WangXinusually_________(get)upat6:30.He________(get)upnow.(2)Meihuausually_________(clean)hisbedroomonSunday.Nowit’snineo’clock.He_________(clean)hisbedroom.(3)Bill_________(notlike)skipping.He_________(like)running.(4)Mymother_________(make)noodlesonSunday.She_________(notmake)pasta.(5)-_________yoursister_________(like)coffee?-No,butshe_________(like)tea.(6)Thebirdsometimes_________(fly)high.(7)Today_________(be)my12thbirthday.Mygrandmother_________(give)meadoll.(8)Thegirlusually_________(plant)manyplantsinthespringeveryyear.(9)Ourmusicteacher_________(teach)usmusiconMondayafternoon.(10)Heusually_________(water)theminthemorning.(11)Healways_________(clean)slowlyand________(look)leftandright(12)Theyounglady_________(clean)herbedroomeveryafternoon.(13)Shenever_________(go)toschoollate,andshealways_________(do)wellinclass.(14)Usually,Tom_________(water)themtwotimesaday.(15)Mayusually_________(plant)manytreesinspring.(五).仿照例句,写出下列动词的形式.例:singsingssinging(1)cut_________________________(2)catch_________________________(3)swim________________________(4)take_________________________(5)get_________________________(6)run________________________(7)ask_________________________(8)brush_________________________
