試題解析：考查be clear about和clear to的用法，be clear about意思“對……明白”， clear to意思“明白的”，句子意思“你明白在課堂上所教的內(nèi)容嗎？也就是說，課堂上交的每個東西你都明白嗎？”，所以選D
考點：考查be clear about和clear to的用法
點評：注意句子Are you clear about what has been taught in this class?是個賓語從句，從句what has been taught in this class?做介詞about的賓語，關(guān)系代詞what引導(dǎo)；句子That is: Is everything that has been taught in this class clear to you?從句that has been taught in this class對先行詞everything解釋說明的，并且不做成份，所以是同位語從句。
