(1) "need" 當(dāng) (main verb) 用時(shí)應(yīng)該加 "to" :
(a) I think he doesn't need to worry about his health.
(b) He needs money to buy a car.
(c) He needs to work as he has a big family.
(d) He needs to go.
(e) Does he need to go so soon?
(f) He doesn't need to go.
(2) 當(dāng) (auxiliary verb) 用時(shí)不能加 "to":經(jīng)常只使用 (present tense).
(a) I think he needs worry about his health.
(b) I think he needs not worry about his health.
(c) He needn't go.
(d) Need he go so soon?
(3) 助動(dòng)詞 auxiliary verbs = need,can,may...你好 請(qǐng)問(wèn)這句怎么回答 I think he ______ worry about his health.上面已經(jīng)給你答案了:用<助動(dòng)詞> (auxiliary verb):(a) I think he worry about his health. 他需要擔(dān)心...或(b) I think he worry about his health. 他不需要擔(dān)心...親 可是應(yīng)該是 needs to 還有needs not不行 如果是否定的話是 I don't think he needs to worry about his health.似乎從句不能否定 只能在主句里否定需要看上下文/前后關(guān)系 [context]. (c) I think he needs (to) worry about his health. 亦沒(méi)錯(cuò)!
