参考答案：A进入在线模考
句意：关于这件事，你最好去问问你父母。本题考查的是had better的用法。Had better。意为“最好”，用于表示对别人的劝告或建议。had better后面必须跟动词原形，构成had better do sth．句型。故A正确。
【知识拓展】在使用情态动词had better时，需要注意以下几点：(1)主语不论是第几人称，句子不论是什么时态，had better的形式都不变。例如：Now you(he，we)had better listen to the teacher．你(他，我们)现在最好听老师讲。(2)had better可用于下列时态：l)一般现在时。例如：Now you had better listen to the radio．你现在最好听收音机。2)一般将来时。例如：You had better start tomorrow．你最好明天动身。(3)had better的否定式是将否定副词not直接放在had better的后面。例如：You had better not miss the last bus．你最好不要错过末班公共汽车。
