Must如果當(dāng)助動(dòng)詞用,后方加的是不帶TO的不定式.
Must do sth.
如果用作名詞,句型就不是這樣寫,應(yīng)該是：
It's a must to do sth.
所以你這邊表達(dá)都不對(duì) 應(yīng)該表達(dá)為l must work 這邊的must是助動(dòng)詞must be 這種句型怎么用？謝謝這時(shí)候的must還是助動(dòng)詞 表示必須這時(shí)候的動(dòng)詞是be動(dòng)詞1,English must be studied to get good grades.2,Rooms must be cleaned to keep healthy.3,Books must be read to gain knowledge.4,Children must be educated to grow up.5,Cotton-padded clothes must be woren to keep warm.6,Buses must be taken to go to outskirts.7,Trees must be planted to greening.8,Mood must be cooled off to thinking.9,Cellphones must be used to communicate.10,Bags must be used to contain things.
