  请给出正确答案并说明原因
answer: 1.B 不定式做主语表示“为了……”的意思，而第一句想要表达的是：
      为了赶第一班公车，他们走的很急。
  2.D remind sb to do sth 是固定用法，意思是：
      Lily,我下午要起购物中心，请帮我邮信。
      send sb to do sth,意思是：派遣
      force sb to do sth,意思是：强迫，逼迫
      help sb (to) do sth,意思是：帮助，帮忙
      本题属于理解题，按句法考虑，B和D都符合，但从句意看来，D比较合适，因为国外邮筒都设置在便利店里，方便人们买邮票后直接邮信，而国内邮筒也设置在路边较显眼的地方，而说话人因为要出去，所以是正好顺路，因此应该选remind,指出门前提醒我一声。
