单选题 Modern American music is rich in its variety of forms, styles, and instruments. A complete encyclopedia (百科全书) of American music is a small library! By just looking at a few types of American music, we can see much diversity. Blues music, which goes back to the 1860s, has African American roots. Blues singers often sing of sad themes: feelings of loneliness or hunger, or being far away from home. The banjo and the washboard were common instruments in early blues music. The harmonica, guitar, and piano are some of the many other instruments used in blues. Jazz has its beginnings in the 1890s in New Orleans. The musical contributions of people from many parts of the world came together in this port on the Mississippi River to create the early versions of jazz. Now jazz comes in many forms and is popular in the United States and many other countries. The fiddle is a common instrument in early country music, but today we hear many kinds of instruments in country music, especially the guitar. Cowboy movies in the 1930s and 1940s helped to make country music very popular. Rap music has its origins in New York in the early 1970s. Rap uses a lot of rhyming. Rhymes are words that sound the same. Many young people like the beat in rap music. Like all music, modern American music causes people to sing, dance, smile, and cry. American music is sometimes controversial (有争议的), but it shows us the diversity of American culture.

【答案解析】解析：本题为细节题。需要明确“爵士乐的发源地”。选项A．Africa与Blues相关，但第二段第一句中的“African”并非指发源地，而是指有着美国非洲裔的血源；选项B．SouthAmerica在文中没有提及；选项C．New York则是Rap的发源地；文章第三段第一句“Jazz hasits beginning in the 1890s in New Orleans．”，因此选项D是正确答案。

单选题 Which of the following contributed to the popularity of country music?

【正确答案】 A

【答案解析】解析：本题为细节题。要说明“哪一选项内容对乡村音乐的推广起到了积极作用?”的问题。根据短文第四段最后一句话“Cowboy movies in the 1930s and 1940s helped to make country music very popular．(二十世纪三四十年代的牛仔电影使得乡村音乐变得非常流行。)”可以判断选项A是正确的。选项B意为“各种各样的乐器”则只是说明乡村音乐中使用了多种多样的乐器，并没有说明对乡村音乐的推广作用；选项C则只是提到了音乐百科，但文章第一段只是说音乐百科像一个小图书馆，并没有说明对乡村音乐起到推动作用；选项D所说的来自世界各地的人们则是对最初形式的爵士乐起到了一定的作用。

单选题 The word "diversity" (Para. 1 and Para. 6) most probably means______.

【正确答案】 C

【答案解析】解析：本题为词义猜测题。文章第一段最后一句的意思是“只需看看美国音乐的一些类型，我们就能看出许多diversity。”之后四段都是在讨论美国不同的音乐。第六段中说“美国音乐有时颇有争议，但却给我们展示了美国文化的diversity。”由此可见选项C表示的“多样性”是正确答案。而background(背景)、influence(影响)和significance(意义)均不符合题意。
