[9] Many people enjoy secret codes. The harder the code, the more some people will try to figure it out. In war time, codes are especially important. They help army send news about battles and the size of enemy forces. Neither side wants its codes broken by the other. [11] One very important code was never broken. It was used during World War Ⅱ by the Americans. It was a spoken code never written down. And it was developed and used by Navajo Indians. They were called “the Navajo code talkers”. The Navajos created the code in their own language. Navajo is 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 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 to 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] The code talkers played an important part in several battles. They helped troops coordinate their movements and attacks. After the war, the U.S. government honored them for what they had accomplished. Theirs was the most successful wartime code ever used.
Questions 9 to 11 are based on the passage you have just heard.
9.What does the speaker say many people enjoy doing?
10.What do we learn about the Navajo code talkers?
11.What is the speaker mainly talking about?
选项
A、They helped the U. S. army in World War Two.
B、They could write down spoken codes promptly.
C、They were assigned to decode enemy messages.
D、They were good at breaking enemy secret codes.
答案
A
解析
浏览四个选项,根据选项中出现的helped,write,decode,breaking等词可以推测,该题可能涉及对某些人的评价或者描述。题干问的是关于纳瓦霍族密码员,我们可以了解到什么。短文最后提到,纳瓦霍族密码员在几次战役中都发挥了巨大的作用。他们帮助军队协调他们的行动和袭击。第二次世界大战结束之后,美国政府对他们取得的成就进行了表彰。故答案为A(他们在第二次世界大战中帮助了美国军队)。B项(他们能够立刻写下口语密码)、C项(它们被指派破解敌人的密码)和D项(他们擅长破解敌人的密码)原文均未提及,故排除。
