We dont like vegetables.He likes ice cream. She doesnt like strawberries.

3、二只有主語在第三人稱單數(shù)時(shí)用動(dòng)詞的“三單形式，其他人稱用動(dòng)詞原形。 動(dòng)詞三單形式的變化規(guī)那么：1.1多數(shù)直接在動(dòng)詞詞尾加-s. play plays like likes ask-asks work-works get-gets call-calls2以字母s, x, ch, sh或o結(jié)尾的動(dòng)詞，在詞尾直接加-es. watch-watches wish-wishes do-does go-goes 3以“輔音字母加 - y結(jié)尾的動(dòng)詞，要先變y為i再加-es. try-tries study-studies cry-cries fly-flies2.不規(guī)那么變化：be- is have-has

(be后not莫忘記)例：陳述句：She is my sister.疑問句 Is she your sister? Yes, I am./ No, Im not.否認(rèn)句 She is not my sister.陳述句：I can play soccer.疑問句 Can you play soccer? Yes,Ican./ No, I cant.否認(rèn)句 I can not

Yes, theyre./ No, they arent.Are those Jims brothers? Yes, theyre./ No, they arent.3當(dāng)句子中沒有be動(dòng)詞，也沒有情態(tài)動(dòng)詞時(shí)，變一般疑問句時(shí)，在主語前加助動(dòng)詞do (I, we,

6、 you,以及復(fù)數(shù)), does第三人稱單數(shù)she,he,it等變成問句；4變否認(rèn)句時(shí)，在主語后謂語動(dòng)詞前加助動(dòng)詞dont, doesnt變成否認(rèn)句，切記：助動(dòng)詞后的動(dòng)詞那么復(fù)原成動(dòng)詞原形。例：陳述句：We get up起床 at 7:00 every morning.疑問句Do you get up at 7:00 every morning?否認(rèn)句We dont get up at 7:00 every morning.陳述句：She has a brother.疑問句 Does she have a brother? 否認(rèn)句 She doesnt have a brother. 在一般現(xiàn)
