一、完形填空(每小题1分,满分15分)
In the 1880s, gold was found in Alaska, the USA. Many people came to the area hoping to get 1. New towns were built and grew bigger in a short time. A town called Iditarod grew so quickly during 1909 that it became the 2 city in Alaska. In the summer months, people could take things to those towns by 3, but the rivers were frozen in winter. And there was no way to get there. So a winter track(小道) was opened up. And people would use teams of 4 to pull sleds(雪橇).
The track became known as the Iditarod Track. It took a team of dogs about three weeks to travel 5 Alaska. They stopped at "roadhouses", which could offer drivers hot drinks and 6 beds to fight against low temperature. The track was used every winter until the 7 came into use in the 1920s.
However, in 1925, a disease called diphtheria(白喉) 8 the city of Nome. The disease could be cured, but 9, the medicine was in Anchorage, right on the other side of Alaska. Planes were still quite new, so 10 knew if they could fly in such cold weather. After some discussion, people 11 that the medicine would be carried using a team of dogs instead.
The trip was over 1,000 kilometres. Most of it was along the Iditarod Track. 12 the trip was hard and tiring, it took the team just six days to finish it. When noticing danger, a dog called Balto stopped the team at once and 13 a much safer way to go. Finally, many people were saved and Balto became the hero of the team.
Nowadays a dog sled race is held every year from Anchorage to Nome, 14 the same way of that famous trip in 1925. This yearly race isn't 15 a competition—it's also a way to remember how great those dogs were! Like them, we should never give up when facing difficulties.

【分析】
这篇完形填空围绕美国阿拉斯加Iditarod小道的起源、狗拉雪橇队运送药品的英雄事迹及如今的狗拉雪橇比赛展开。解题需紧扣上下文语境和逻辑关系：
1. 第1空：前文提及人们来阿拉斯加淘金，核心目的是致富，结合选项可锁定答案。
2. 第2空：根据“grew so quickly”可知小镇发展迅猛，由此推断其成为阿拉斯加规模最大的城市。
3. 第3空：后文提到冬季河流结冰，反向推导夏季可通过河流运输，对应乘船的方式。
4. 第4空：后文多次出现“team of dogs”的表述，明确是用狗队拉雪橇。
5. 第5空：结合语境是穿越阿拉斯加，“across”侧重从一端到另一端，符合文意。
6. 第6空：冬季气温极低，roadhouses提供热饮和温暖的床抵御寒冷，对应“warm”。
7. 第7空：后文提到“Planes were still quite new”，说明1920年代飞机开始投入使用。
8. 第8空：“hit”可表示疾病侵袭某地，契合白喉袭击Nome市的语境。
9. 第9空：疾病可治疗但药品在千里之外，这是令人惋惜的处境，选“sadly”。
10. 第10空：飞机当时尚属新型交通工具，没人知晓它能否在严寒天气飞行，用“nobody”。
11. 第11空：经过讨论后，人们达成共识用狗队运药，“agreed”符合逻辑。
12. 第12空：“旅途艰难”和“仅用六天完成”是让步关系，用“Although”引导让步状语从句。
13. 第13空：Balto察觉危险后停下，选择了更安全的路线，“chose”符合语境。
14. 第14空：如今的比赛沿袭1925年那次旅程的路线，“following”表示沿着、遵循。
15. 第15空：比赛不只是竞赛，更是纪念方式，“just”表示“仅仅”，契合文意。
