Module6Atriptothezoo.Unit3Languageinuse当主语是第三人称单数，表示经常性、习惯性的行为时，我们这样表达：ShespeaksEnglish.Helivesfarawayfromschool.如果表示不常做某事，该怎样表达呢？她不说英语。他住地离学校不远。Shedoesn’tspeakEnglish.Hedoesn’tlivefarawayfromschool.你能总结出什么呢？主语是第三人称单数的行为动词的一般现在时否定形式是在行为动词前加doesn’t(doesnot),这时要注意把谓语动词还原为动词原形。试比较肯定与否定句中行为动词形式的变化：肯定：Hegetsupveryearly.他起床很早。否定：Hedoesn’tgetupveryearly.他起床不很早。如果要问别人是否经常做某事，我们要采用下面的表达方式：—Doesthepandaeatmeat?熊猫吃肉吗？—No,itdoesn’t.不，它不吃。—Doesiteatbamboo?它吃竹子吗？—Yes,itdoes.是的，吃。从以上例子可以看出，行为动词的第三人称单数一般现在时疑问形式是在句首加助动词does,而加does之后，后面的谓语动词像否定句一样也要用原形。试比较:肯定：Hegetsupveryearly.他起床很早。疑问：Doeshegetupveryearly?他起床很早吗？肯定句：主语+动词的第三人称单数形式否定句：主语+doesn’t+动词原形疑问句：Does+主语+动词原形？Yes,主语+does.No,主语+doesn’t.现在我们把行为动词第三人称单数的各种句式总结如下：Completesentences.(Activity3)Theelephant_____(like)water.likes1.Thesnake_____(come)fromAmerica.2.Snakes____(live)inAsia,Africa,AustraliaandEurope.3.Themonkey____(eat)fruit.4.Monkeys____(come)fromSouthAmerica.comesliveeatsdoesn’teatdon’tlivedoesn’tcomecome把上述句子改为否定句。don’tcomeWritequestionsandshortanswers.panda/eat/bamboo?camel/live/desert?elephant/work/forest?kangaroo/eat/meat?monkey/comefromAfrica?snake/like/water?wolf/live/jungle?Askandanswerabouttheanimals.(Activity1)Name:MeimeiHometown:Sichuan,ChinaFavouritefood:BambooFavouriteactivity:ClimbingtreesDoesMeimeicomefromSichuan,China?Yes,itdoes.DoesMeimeicomefromSichuan,China?Yes,itdoes.Name:LuluHometown:Sichuan,ChinaFavouritefood:FruitFavouriteactivity:JumpingandclimbingtreesCompletethewordmapwiththesewords.(Activity4)AfricaAmericaAsiacameldesertEuropeforestjunglemeatmonkeypandapolarbearsnaketheArctictigerwolftheArctic-_________-meat.-ju...
