解析:
被动语态：
1：英语中语态有两种：主动语态和被动语态。
语态的作用：语态是动词的一种形式，用来说明主语和谓语之间的关系。
语态的选用：如果主语是动作的执行者，谓语用主动语态。
例如：We clean the room every day.
如果主语是动作的承受者，或者说是动作的对象，谓语则是要用被动语态。
例如：The room is cleaned every day.
被动语态由“助动词be + 急务动词的过去分词”构成。助动词be 有人称、数和事态的变化，其变化规则与be 作为连系动词时完全一样。

喻炭菁虽然选项C) have to be said也是被动语态,但当what做主语时,谓语动词要用单数has,而不是have。而且,have to be said(不得不说)的意思和全句不合,不可能是本题的答案。B) must say 和D) need to say这两个选项的动词都是主动语态,因此,都不是本题的答案。18) 不定式的被动语态:to be done...
