你的句子中用need不對.因為need用作情態(tài)動詞時,只能用作疑問句或否定句；作實義動詞時,need后面需+to ..所以,還是用should 好.老師，你可以幫我詳細(xì)講解一下need的用法嗎，我給金幣的：）。謝謝哈！舉例說明情態(tài)動詞need用作情態(tài)動詞時，只能用作疑問句或否定句——Need i do it now ?----No, you needn't He needn't return it today 實義動詞needI need to see my uncle tomorrowYon don't need to see him todayHe needs to leave at once He doesn't need to leave now Does he need to leave now ?老師那在允許我問問我曾經(jīng)看到這樣的句子government neednot to forbid the tobaccoyou need cleaning your house第二句是實意動詞的動名詞形式吧government neednot to forbid the tobacco這句不對，need后加了not ，need是情態(tài)動詞，后面怎么還有個to呢？應(yīng)該去掉to you need cleaning your house也不對，應(yīng)該是Your house needs cleaning =Your house needs to be cleaned
