1.He didn't become a person who his father wanted him to be .在這個(gè)定語(yǔ)從句中,先行詞是person,關(guān)系代詞是who,從句的主語(yǔ)是his father,賓語(yǔ)是him,who做表語(yǔ),邏輯上是his father wanted him to be who.
2,The boy who I know studies best in his class 中,studies 是主句的謂語(yǔ),當(dāng)然取決于主句的主語(yǔ),主句的主語(yǔ)是the boy,三單,故用了studies.一般來(lái)講,這與先行詞無(wú)關(guān)的.只不過(guò)這里的先行詞剛好就是主語(yǔ).
此外,定語(yǔ)從句的謂語(yǔ)動(dòng)詞的單復(fù)數(shù)要跟先行詞一致的.至于時(shí)態(tài),則要看從句具體表達(dá)的語(yǔ)境來(lái)定.從句的時(shí)態(tài)與主句的時(shí)態(tài)并無(wú)直接的關(guān)系,是互相獨(dú)立的.
祝你進(jìn)步.
