"Popular art" has a number of meanings, impossible to define with any precision, which range from folklore to junk. The poles are clear enough, but the middle tends to blur. The Hollywood Western of the 1930’s for example, has elements of folklore, but is closer to junk than to high art or folk art. There can be great trash, just as there is bad high art. The musicals of George Gershwin are great popular art, never aspiring to high art. Schubert and Brahms, however, used elements of popular music--folk themes--in works clearly intended as high art. The case of Verdi is a different one: he took a popular genre-bourgeois melodrama set to music (an accurate definition of nineteenth-century opera) and, without altering its fundamental nature, transmuted it into high art. This remains one of the greatest achievements in music, and one that cannot be fully appreciated without recognizing the essential trashiness of the genre.
As an example of such a transmutation, consider what Verdi made of the typical political elements of nineteenth-century opera. Generally in the plots of these operas, a hero or heroine--usually portrayed only as an individual, unfettered by class--is caught between the immoral corruption of the aristocracy and the doctrinaire rigidity or secret greed of the leaders of the proletariat. Verdi transforms this naive and unlikely formulation with music of extraordinary energy and rhythmic vitality, music more subtle than it seems at first hearing. There are scenes and arias that still sound like calls to arms and were clearly understood as such when they were first performed. Such pieces lend an immediacy to the otherwise veiled political message of these operas and call up feelings beyond those of the opera itself.
Or consider Verdi’s treatment of character. Before Verdi, there were rarely any characters at all in musical drama, only a series of situations which allowed the singers to express a series of emotional states. Any attempt to find coherent psychological portrayal in these operas is misplaced ingenuity. The only coherence was the singer’s vocal technique: when the cast changed, new arias were almost always substituted, generally adapted from other operas. Verdi’s characters, on the other hand, have genuine consistency and integrity. Even if, in many casals, the consistency is that of pasteboard melodrama, the integrity of the character is achieved through the music: once he had become established. Verdi did not rewrite his music for differenf singers or countenance alterations or substitutions of somebody else’s arias in one of his operas, as every eighteenth-century composer had done. When he revised an opera, it was only for dramatic economy and effectiveness.

A:quite accurate B:rather elusive C:fairly clear D:very dubious

The iPod revolutionized the way we consume music. The iPhone made us crazy for apps. And now the iPad is getting ready to rock our love lives—or at least help improve our search for someone to communicate with. In late May, Skout.com will become the first dating site to launch an iPad application. The free app will be similar to the version that’s already available to phone users: members can enter search criteria, such as age range, gender and physical preferences, and a HotMap will show in real time the locations of active Skout users who fit those criteria. The idea is to help members meet up and see if magic happens. The cool thing about the iPad adaptation, says CEO Christian Wiklund, is that its screen is large enough to let the user view the map while simultaneously chatting and searching through another member’s photos.
David Evans, editor of onlinedatingpost.com, says we can expect to see more innovative technology in a few months after companies get acquainted with the capabilities of the iPad. "What I’m looking for are dating sites that are optimized for the iPad, with features native to the sleek computing device like (touch screen motions such as) pinch, twist, zoom and shake," he says. "It’s the iPad that’s going to enable developers to create entirely new ways to browse, discover and connect with singles."
Steve Odom, CEO and founder of dating site Gelato, which launched last year and includes a live feed of members’ social-media profiles, is redesigning his entire website based on the iPad’s appearance. Profile pictures play a key role in online dating, Odom says, and the iPad gives sites an opportunity to play up the presentation of their clientele. "It’s big, it’s beautiful, and it’s perfect for dating sites," says Odom, who plans to unveil the redesign in June.
Evans predicts that online dating sites will begin to display their content like a magazine, letting users flip through pages of profiles and enlarge photos while simultaneously texting with one or more others. He says there’s also been talk of adding a facial-coding and eye-tracking function that would use a webcam on the iPad to refine suggested matches based on a member’s responses to certain profiles. If you grimace, the profile will fade away; if you smile or if your pupils dilate, similar profiles will be suggested. In other words, some day there could be an iPad app for love at first sight.

A:could be used to browse the profile pictures more quickly B:is developed based on a member’s response C:can enable the users to get accurate matches more easily D:could support checking profile pictures and texting at once

Passage 2
According to figures from the U.S. Bureau of Labor Statistics, the average weekly income for a woman in 1983 was $ 260. For the same year, men had average weekly earnings of $ 393. For some people, these figures are clear evidence that there is still sex discrimination in the area of pay in the U. S. However, I would argue that this explanation is too simple. In order to get an accurate picture of the situation, we must examine the types of jobs which are typically held by men and by women. When we do this, we find that certain occupations seem to be primarily female while others seem to be primarily male occupations. In the medical and legal professions, for example, statistics show that 85% of all doctors and lawyers are men (although this situation is changing). More than 90% of all engineers are men. Women, however, have been the majority for a long time in other occupations. For example, 99 out of every 100 secretaries are women, and 95% of all nurses are female. From these statistics, it is clear that women tend to enter certain occupations and not others. The occupations which they enter are often in service industries and often have one common feature: They do not pay well. It can be argued that this is the principal reason for the difference in earnings between men and women. In addition, we can expect the pay situation to change in the future, because more qualified women are beginning careers in medicine, law, business, scientific research, and engineering.

A:The majority of people working in medical prfessions are male. B:The difference between men' s pay and women' s pay will become larger and larger. C:There is still a differencer between the earnings of men and women. D:Women and men will exchange theil jobs in most areas.

— Whose umbrella is it
— It's ______.

A:somebody else's B:somebody else C:somebody's else's D:somebody's else
