B．might C．could D．wouldneed的用法【知識積累·練前熱身】【知識積累·練前熱身】這兩詞既可做實義動詞用，又可做情態動詞用。作為情態動詞，兩者都只能用于疑問句，否定句和條件句。need作實義動詞時后面的不定式必須帶to，而dare作實義動詞用時,后面的to時常可以被省略。1.need的用法（1）need可用作實義動詞,意為"需要；必要",后面可接名詞、動名詞或動詞不定式等作賓語。注意"needdoing"表示被動意義,相當于needtobedone。例如：Ineedadictionary,soIneedtogotothebookstore.我需要一本詞典,因此我要去趟書店。Howoftendoesyourhairneedwashing(needtobewashed)?你的頭發需要多久洗一次？（2）need可用作情態動詞,通常用于疑問句和否定句中,后接動詞原形。這時need沒有人稱和數的變化,也沒有時態的變化，need后加do，否定形式為neednot。例如：It'sonlyeighto'clock.Needyougosoearly?才八點。你需要去這么早嗎？Yes,Imust./No,Ineedn't.是的，我必須去/不，我不需要了。Youneedn'ttellhimaboutitasIhavetoldhim.你不必跟他說那件事，我已經告訴他了【鞏固練習】1．You________worryaboutyourbrother.Hewillgetwellsoon.A．must
