23、uest, desire, insist 等表示“建议”、“要求”、“命令”、“决定”、“安排”、“计划”、“主张”的动词后面接的宾语从句中。这里的 should 也可以省略。本句中should 作为情态动词，可以用来表示意外、惊喜或者在说话人看来是不可思议的，常常译为竟会、居然，住的这么近的邻居居然不认识。表示意外，所以答案选C。14he law is equally applied to everyone.

26、出意思，比较好理解。The lights were out. They must have been asleep. 灯灭了，他们应该睡觉了。should have done本该做某事却没做，should是应该，重点记忆最后的结果是没做某事。You should have told her that you loved her.你本应该告诉她你爱她。could have done字面意思是可能已经做了某事，也可用作本能做却没做某事，重点记忆最后的结果是没做。You could have reviewed, but you played games all night.你本可以复习的，但你一晚上
