36. A.examined B.warned C.interviewed D.cured
37. A.harmless B.helpless C. fearless D.careless
38. A.Moreover B.Therefore C.Otherwise D.However
36. 此句中并没有提到治愈疾病或者没有，但直到文章结尾处才反映了疾病最终被治愈，所以此处极有可能只是检查并确认病症，所以用examined.
37.首先要理解if引导的从句中主要it指代白喉这种致命的疾病，然后我们还得了解句中的struck(原形strike)在此处是什么意思。再根据句意使用排除法选择helpless.
strike有多种汉语含义，如（1）击打，（2）报时，（3）袭击，（4）划（火柴）， （5）吸引，（6）（主意，想法）突然闪过某人的脑海，（7）罢工。
引出的短语及句型包括：
1.The clock was striking twelve when I passed by the square.
2.strike a match
3.striking (adj.) 吸引人的
4.It struck sb that… 某人突然想到…
5.The/An idea struck through one's mind 某人突然想到…
6.go on strike/ be on strike(名词)
38.考查上下句之间的关系。根据句意，两个半句之间属于转承关系，所以用连词however.
How could the medicine get to Nome? The town`s 39 was already full of ice, so it couldn`t come by ship. Cars and horses couldn`t travel on the 40 roads. Jet airplanes and big trucks didn`t exist yet.
41 January 26, Billy and three other children had died. Twenty more were 42 . Nome`s town officials came up with a(n) 43 . They would have the medicine sent by 44 from Anchorage to Nenana. From there, dogeled(狗拉雪橇)drivers—known as “mushers”—would 45 it to Nome in a relay(接力).
39.A.airport B.station C. harbor D.border
40.A.narrow B. snowy C.busy D.dirty
41.A.From B.On C.By D.After
42.A.tired B.upset C. pale D.sick
43.A.plan B.excuse C.message D.topic
44.A.air B.rail C. sea D.road
45.A.carry B.return C. mail D.give
39.根据此句中的by ship 可知作者意在强调水路不通，再有就是要认知harbor这个单词的汉语意思。
41.考查介词的使用，从语法角度讲，on和by都可以搭配，但是后面所搭配的句子时态决定了答案。on加时间名词做状语，主句要用一般过去时；而by加时间名词做状语，主句要用过去完成时。所以得出答案C。
