1、Unit 5Do you have a soccer ball?七年級英語上冊（浙江地區(qū)）第三課時Section A (Grammar Focus3c)單元同步語法精講一般現(xiàn)在時的謂語動詞可以由be動詞(前面已經(jīng)學(xué)過)或?qū)嵙x動詞來充當(dāng)。今天我們重點學(xué)習(xí)含實義動詞的一般現(xiàn)在時。1意義：一般現(xiàn)在時可以用來表示現(xiàn)在的狀態(tài)，主語的性格和能力以及經(jīng)常性或習(xí)慣性的動作。2謂語動詞：當(dāng)主語是第三人稱單數(shù)(he，she，it)、單數(shù)名詞或不可數(shù)名詞時，謂語動詞也要相應(yīng)地使用第三人稱單數(shù)形式(本單元中講的是動詞have，其第三人稱單數(shù)形式為has)。當(dāng)主語是第一人稱(I，we)，第二人稱(you)，第三人稱復(fù)數(shù)

2、(they)及其他復(fù)數(shù)名詞時，謂語動詞則以原形出現(xiàn)。eg：I have an orange.我有一個橙子。Tom has a friend.湯姆有一個朋友。3句式變形：變否定句時，當(dāng)謂語是第三人稱單數(shù)形式時，在謂語動詞前加doesnt，此時要注意其后的動詞變成原形；當(dāng)謂語動詞是原形時，在謂語動詞前直接加dont即可。eg：My brother doesnt have a basketball.我弟弟沒有籃球。The girls dont have computer games.女孩們沒有電腦游戲。變一般疑問句時，當(dāng)謂語是第三人稱單數(shù)形式時，在句首加助動詞Does，句中謂語動詞變?yōu)樵?；?dāng)謂語動

3、詞是原形時，在句首直接加助動詞Do。其肯定回答為“Yes，主語do/does.”；否定回答為“No，主語dont/doesnt.”。eg：Do you have a basketball？你有(一個)籃球嗎？Yes，I do./No，I dont.是的，我有。/不，我沒有。Does she have a tennis ball？她有(一個)網(wǎng)球嗎？Yes，she does./No，she doesnt.是的，她有。/不，她沒有。單元同步語法精練 一、用have的適當(dāng)形式填空。1I _ a new friend.2_ Grace _ a bag?3She _ five baseballs.4_
