文章大意：这是一篇记叙文。Nome小镇里的孩子们感染了白喉病。为了挽救孩子们，

一些勇士们展开了雪橇接力赛，冒着危险，日夜兼程地把药品安全运到小镇上，孩子们最终得救了。

1．A.examined B．warned

C．interviewed D．cured

解析：根据下文中的“and knew he had diphtheria”可知，应填examine“检查(身体)”，表示Dr.Welch给一个生病的男孩做了检查。

2．A.harmless B．helpless

C．fearless D．careless

解析：上文说这种病主要传染给孩子，下文说如果这种病袭击这个镇子，因此根据语境，应选B，表示如果发生这种情况的话，那么这里的孩子们就会很无助了。helpless表示“无助的，无能为力的”。

3．A.Moreover B．Therefore

C．Otherwise D．However

解析：上下文语境表示转折含义，因此选D，表示“然而，可是”，指可是最近的供应物也远在一千多英里之外。

4．A.airport B．station

C．harbor D．border

解析：下文说用船只送药的方法不可行，因此这里选C，指这个小镇中船只进出的港口已经被冰覆盖。harbor“港口”。

5．A.narrow B．snowy

C．busy D．dirty

解析：根据语境和上文的“full of ice”可知，这里说的是汽车和马不能在被雪覆盖的道路上行进，因此选B表示“被雪覆盖的”。

6．A.From B．On

C．By D．After

解析：根据下文的“had died”可知，此处表示在1月26日之前，Billy和其他三个孩子已经死去了。故用by表示“在……之前，到……为止”。

7．A.tired B．upset

C．pale D．sick
