第三人稱單數,動詞後是不是要加s或es susan can't speak English.此句話中speak為什麼不加s susan是一個人名第三人稱單數,動詞後應該加s或es啊? 2,saly is going to type he boss's此處type後為什麼不加s 3,His sister can cook for the family.此處也是第三人稱單數,cook後為什麼不加s

首先,本來第三人稱單數(三單)後,動詞也要跟住主語用單數(加s或者es)但是如果有了情態動詞,動詞就不需要加s後者es情態動詞有can,could,shall,should,may,might,ought to等.如果動詞前面有to,那麼動詞用原型.to+動…



who的特殊疑問句的謂語動詞用第三人稱單數嗎?為什麼?


WHo後面可跟單數或複數謂語.視情况而定如
who is the man that stands there?
Who are the people that are present the meeting?



為什麼特殊疑問句中的'who“後接單數第三人稱形式?


who後面可以加單數或複數eg:who is that woman
who are your parents
關鍵是看賓語是單或複數
