a.is done b.does c.is drawn d.are done为什么是Ａ，能翻译并说明其它答案吗／／

465. must 的反义疑问句比较特殊,也就是你看到的,还是用 must.非要说个理由的话,就用排除法吧.首先 should I 八杆子打不着.再有, must (必须)的反义词是 needn't (不须),而不是 mustn't (不行),所以按照一般的反义疑问句构成法,应该用 needn't I.但是,这就是个惯性问题了,前面是 must,怎么突然后面就变成 needn't 了?这让人听起来很别扭.所以为了听着舒服,还是用 must I.
- You must do as you are told!
- Oh, I must, must I?
翻译: - 你必须照我说的去做!
- 呵,我必须这么做,不是吗? (注:这还是一句反义疑问句,所以翻译还是"不是吗?")

471．Here is a rule for you to remember: No drawing is done on the wall.
翻译:有条规定请你记住:不要在墙上涂鸦.
很明显的这里要用被动语态.所以 does 是肯定不对的.至于 draw drawing 怎么也不如 do drawing 来得顺耳(况且 do drawing 是个固定搭配).剩下的选项A和D中, no drawing 的数量是零,所以在数量为零或一的情况下,应用 be 动词的单数形式 is.不过要我填的话,我会填 is to be done 或 must be done.
