What you did ____ the school rules. So next time you're late, don't try to slip into the classroom without ____ by the teacher. A. go against; being noticed B. goes against; being noticed C. went against; noticing D. went along with; noticing 答案选Ｂ what you did在这里是个主语从句。goes against是句子谓语.之所以用goes第三人称单数，是因为把主语从句看成一个抽象整体，“你所做的事情” 然后第2个空，肯定是"被"注意到，"被"发现，用被动。
