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(前面已經學過)或實義動詞來充當。今天我們重點學習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常性或習慣性的動作。2謂語動詞:當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)。當主語是第一人稱(I,we),第二人稱(you),第三人稱復數(shù)
2、(they)及其他復數(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?;當謂語動
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的適當形式填空。1I _ a new friend.2_ Grace _ a bag?3She _ five baseballs.4_
