小题1:on
小题2:arrives
小题3:price
小题4:kind
小题5:pay
题目分析：
小题1:考查介词的用法。在具体的一天前面用on。句意为：我想订三月十三日去泰山的票。故填on。
小题2:考查固定搭配的用法。arrive at/in到达。and前后连接两个动词时，第一个动词用什么时态，第二个动词就用什么时态，本句中and前的动词用第三人称单数的形式，故arrive也要用单三形式。故填arrives。
小题3:考查名词的用法。what about怎么样？根据下文回答价格，可知本句问多少钱？price价格。故填price。
小题4:考查名词的用法。因为上文说有两种车票，这里问Kangkang需要哪一种车票。故填kind。
小题5:考查固定短语的用法。pay for支付。句意：请在下午五点半之前支付。故先pay。
