Ⅲ.阅读理解
(2017·全国Ⅰ，C)
Some of the world's most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO(United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying (联合) voice across cultures.
Despite the celebrations, though, in the U．S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.
It's Jason Moran's job to help change that. As the Kennedy Center's artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.
“Jazz seems like it's not really a part of the American appetite，” Moran tells National Public Radio's reporter Neal Conan. “What I'm hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black or white anymore. It's actually colorful, and it's actually digital.”
Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. “The music can't be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same，” says Moran.
Last year, Moran worked on a project that arranged Fats Waller's music for a dance party, “just to kind of put it back in the mind that Waller is dance music as much as it is concert music，” says Moran. “For me, it's the recontextualization. In music, where does the emotion (情感) lie? Are we, as humans, gaining any insight (感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context，” says Moran, “so I want to continue those dialogues. Those are the things I want to foster.”
文章大意：本文介绍了举办第一届国际爵士乐日的宗旨、当前爵士乐面临的挑战以及如何让爵士乐重新流行的设想。
1．Why did UNESCO set April 30 as International Jazz Day？D
A．To remember the birth of jazz.
B．To protect cultural diversity.
C．To encourage people to study music.
D．To recognize the value of jazz.
解析：细节理解题。根据第一段的第二句“UNESCO(United Nations Educational，Scientific and Cultural Organization)recently set April 30 as a day to raise awareness of jazz music，its significance，and its potential as a unifying(联合)voice across cultures.”可知，联合国教科文组织近来把4月30日设立为国际爵士乐日，旨在增强人们对爵士乐价值的认识。故答案为D。
2．What does the underlined word “that” in paragraph 3 refer to？C
A．Jazz becoming more accessible.
B．The production of jazz growing faster.
C．Jazz being less popular with the young.
D．The jazz audience becoming larger.
解析：代词指代题。根据语境可知，画线词that指代上段“Despite the celebrations，though，in the U．S.the jazz audience continues to shrink and grow older，and the music has failed to connect with younger generations.”的内容，即爵士乐听众的数量减少并且趋于老龄化，不受年轻人喜欢的现状。故选C。
3．What can we infer about Moran's opinion on jazz？C
A．It will disappear gradually.
B．It remains black and white.
C．It should keep up with the times.
D．It changes every 50 years.
解析：推理判断题。根据第五段的内容尤其是“It has to continue to move, because the way the world works is not the same”可知，由于时代在改变，人们的娱乐方式已经发生改变，所以爵士乐应该随着时代改变，才能吸引更多的听众。故选C。
4．Which of the following can be the best title for the text？A
A．Exploring the Future of Jazz
B．The Rise and Fall of Jazz
C．The Story of a Jazz Musician
D．Celebrating the Jazz Day
解析：标题归纳题。本文介绍了为保护爵士乐，联合国教科文组织设立国际爵士乐日。纵观全文内容尤其是第三至第六段中提到的杰森·莫兰对爵士乐的看法及希望可知，A项“探索爵士乐的未来”作本文标题最佳。

情态动词表示说话人的某种感情或语气，对某一动作或状态的某种态度，表示“需要”“可以”“应该”等意义。情态动词有以下特征：
1．不能单独作谓语，除ought to和used to以外，后面只能接不带to的不定式。
2．没有人称和数的变化。但有些情态动词，如：can，will，dare有一般现在时和过去时的变化。
3．情态动词的“时态”形式并不是区分时间的主要标志，很多情况下，情态动词的现在时形式和过去时形式都可用来表示现在时间、过去时间或将来时间。二、情态动词的基本用法
(一)can与could的用法
1．表示能力(could是过去式)。
①The clever student can solve such difficult problems in a short time.
