(9)Many people enjoy secret codes, the harder the code the more some people would try to figure it out. In war time, codes are especially important, they help army send news about battles and signs of enemy forces. Neither side wants its code broken by the other. (10-1)One very important code was never broken, it was used during world war two by the Americans. It was spoken code, never written down and it was developed and used by NH Indians. They were called the NH code talkers. The NH created the codes in their own language. NH was hard to learn and only a few people know it. So it was pretty certain that the enemy would not be able to understand the code talkers. In addition, the talkers used code words. They called a submarine and an iron fish and a small bomb thrown by hand, a potato. If they wanted to spell something, they used code words for letters of the Alphabet. For instance, the letter A was ant or apple or ax, the code talkers worked mostly in the islands in the Pacific. One or two would be assigned a group of soldiers. They would send messages by field telephone to the code talker in the next group. And he would relay the information to his commander. (10-2)The code talkers played an important part in several battles. They helped the troops coordinate their movements and attacks. After the war, the US governments honored them for what they had accomplished. Theirs was the most successful wartime code ever used.

未听先知

预览三道题各选项,由各选项中的 Decoding、army、 breaking enemy secret codes可以初步推测 该短文与军用密码的破译有关,再结合选项中的 help the t.s.amy、 World War I、 Pacific War、 military code 等词可以进一步推测,短文内容涉及二战期间美国军队在太平洋区域使用的密码。

详解详析

9.What does the speaker say many people enjoy doing?

短文开头即指出,很多人喜欢密码。密码越难,他们就越想要破译出来。也就是说,很多人喜欢破译秘密消息,答案为C)。


10.What do we learn about the NH talkers?

短文中提到,在二战期间,美国的一种密码从未被敌方破译。这种密码以印第安部落纳瓦霍人的语言为基础发展而来,没有书面形式,只是在纳瓦霍人之间口口相传。纳瓦霍密码员帮助军队协调行动和攻击,在战争中起着重要作用。由此可知,他们在二战期间给予了美国军队巨大的帮助,答案为A)。


11.What is the speaker mainly talking about?

短文以人们喜欢破译密码开头,引出了二战中从未被成功破译的Navajo密码,之后短文对这种密码的编译、使用者、使用方式以及战后美国政府对这些密码人员的奖励进行了介绍。由此可以判断,文章围绕着Navajo密码展开,向读者全面讲述了这种从未被成功破译的密码,答案为C)。
