I feel it is you as well as your wife that ________ for your son's bad performance at school．
A.are to blameB.are going to blameC.are to be blamedD.is to be blamed在线课程A
本题一是考查主谓一致，二是考查习惯用法．本题是个强调句式．主语是“you as well as your wife”，但as well as引导的成分不影响主语的内容．说某人有过失该受非难时通常用“to blame”而很少用“to be blamed”．be going to用于此处不对，它表示“将要、计划做某事”．
