问题 As teachers we should concern ourselves with what is said, not what we think______.

选项 A、ought to be said
B、must say
C、have to be said
D、need to say

答案A

解析 从句子结构我们可以看出,介词 with后面接两个what引导的名词性从句。在前一个从句中,what作主语,is said作谓语:在后一个从句中,what 也是主语,谓语也同样应用被动语态,其中的 we think 是插入语,对句子成分不造成影响。所以A正确。C虽也用了被动语态,但 what作主语时,后面的谓语动词一般应用单数,B和D不是被动语态。
