Unit 5Do you have a soccer ball?七年级英语上册（浙江地区）第三课时Section A (Grammar Focus3c)单元同步语法精讲一般现在时的谓语动词可以由be动词(前面已经学过)或实义动词来充当。今天我们重点学习含实义动词的一般现在时。1意义：一般现在时可以用来表示现在的状态，主语的性格和能力以及经常性或习惯性的动作。2谓语动词：当主语是第三人称单数(he，she，it)、单数名词或不可数名词时，谓语动词也要相应地使用第三人称单数形式(本单元中讲的是动词have，其第三人称单数形式为has)。当主语是第一人称(I，we)，第二人称(you)，第三人称复数(they)及其他复数名词时，谓语动词则以原形出现。eg：I have an orange.我有一个橙子。Tom has a friend.汤姆有一个朋友。3句式变形：变否定句时，当谓语是第三人称单数形式时，在谓语动词前加doesnt，此时要注意其后的动词变成原形；当谓语动词是原形时，在谓语动词前直接加dont即可。eg：My brother doesnt have a basketball.我弟弟没有篮球。The girls dont have computer games.女孩们没有电脑游戏。变一般疑问句时，当谓语是第三人称单数形式时，在句首加助动词Does，句中谓语动词变为原形；当谓语动词是原形时，在句首直接加助动词Do。其肯定回答为“Yes，主语do/does.”；否定回答为“No，主语dont/doesnt.”。eg：Do you have a basketball？你有(一个)篮球吗？Yes，I do./No，I dont.是的，我有。/不，我没有。Does she have a tennis ball？她有(一个)网球吗？Yes，she does./No，she doesnt.是的，她有。/不，她没有。单元同步语法精练 一、用have的适当形式填空。1I _ a new friend.2_ Grace _ a bag?3She _ five baseballs.4_ they _ a daughter?5She _(not) five basketballs.6They _ a volleyball.7_ Lucy _ a sister?8_ your brother _ a soccer ball?9I _(not) a pencil box.10Lily and Lucy _ a room.haveDoeshavehasDohavedoesnt havehaveDoeshaveDoeshavedont havehave11_ you have an eraser?Yes，I _12_ Bob have an English map?No，he _He _ a map of China.13_ they have a telephone in the room?14Sally _ a watch and it is nice.15_ Mike and Bill have model planes?No，they _16We _ schoolbags.But we _ have pens.DodoDoesdoesnthasDohasDodonthavedont三、按要求完成句子。17My brother has a soccer ball.(改为一般疑问句)_ _ brother _ a soccer ball?18I have two tennis bats.(改为否定句)I _ _ two tennis bats.19She doesnt have a tennis.(改为肯定句)She _ _ tennis.20Bob has a pingpong.(用I代替Bob改写句子)_ _ a pingpong.Does yourhavedont havehas aI have21Do your parents have a TV？(作肯定回答)Yes，_ _22He has a tennis bat.(改为复数句)They have _ _23Kate has a pingpong bat.(改为否定句)Kate _ _ a pingpong bat.24Her sister has two baseballs.(改为一般疑问句)_ her sister _ two baseballs?25They have a tape player.(改为一般疑问句)_ they _ a tape player?they dotennis batsdoesnt haveDoeshaveDohave
