On May 17, she attended the 2015 Billboard Music Awards in Las Vegas, US, with pink hair and a blue coat. She looked like a model, but won big as a rapper. The 24-year-old Australian beat out big names like Nicki Minaj and Drake to win the award for Top Rap Artist. It's a great achievement in many people's eyes, but Azalea knew what she wanted from the beginning. At 15 she dropped out of high school because she was only interested in art class. She worked as a house cleaner to save money for her dream the following year. Before her 16th birthday, Azalea left her home, a tiny town in Australia, for the US, making up her mind to become a rapper. Moving from Miami to Houston to Atlanta, she started rapping in the Southern-style accent of her surroundings and her single "Ignorant Art" came out in 2011. From then on, she has never looked back. However, her style has caused lots of discussions. She might be one of the most polarizing artists. She raps with a southern American accent, even though she speaks with an Australian one. Many people comment that she overuses black culture in her music. Her supporters are against it. Female American rapper MC Lyte defended Azalea in an interview, saying she should not be judged because of where she's from. "Hip hop is universal, no color1 lines." MC Lyte said. Azalea herself is proud of her music. "I really want to be focused on what I'm doing," she said in an interview."That's really dangerous when you're trying to figure out ways to entertain people and make them happy. I don't want to be a part of that." Question: By saying "I don't want to be a part of that." Azalea means that _ . Options: A: she's unwilling to become popular B: her music is not for entertainment C: she refuses to learn from other rappers D: her music is not affected by others' taste

It had its beginning in the USA and spread throughout the whole world during the 1950s and 1960s. It is widely liked by the young people. The best known early form of pop music was "rock-n-roll"; another was "blues". A more recent development is "folk-rock". Pop music has taken the place of native music in many parts of the world; it has caused the number of people for jazz to become much smaller than it was in the 1950s and earlier, and it has now begun to rule musical stage productions. It's a big industry. Much pop music is without artistic value, but the work of some pop singers, e.g. the Beatles, Bob Dylan, the groups like Floyd and Crosby, Stills and Nash, is on a higher musical level. And there is still a great interest in it today. Pop music concerts and festivals are held all over the world. *ks*5u Question: Which of the following is TRUE? Options: A: No pop music is on a high musical level. B: Much pop music is very artistic. C: Pop music is highly artistic. D: Not all pop music is without artistic value.

Q: Read the article and select the best answer. Article: Birds that are half-asleep -- with one brain hemisphere alert and the other sleeping -- control which side of the brain remains awake, according to a new study of sleeping ducks. Earlier studies have recorded half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere's eye stays open and alert. Birds also can sleep with both hemispheres resting at once. Decades of studies of bird groups led researchers to predict extra alertness in the end-of-the-row sleepers which tend to be attacked more easily. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction. Also, birds napping at the end of the line depend on single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Turning 16 birds through the positions in a four-duck row, the researchers found that compared with 12 percent for birds in inner spots, outer birds half-asleep during some 32 percent of napping time. "We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness at the same time in different regions of the brain," the researchers say. The results provide the best evidence for a long-standing assumption that single-hemisphere sleep developed over time as creatures scanned for enemies. The preference for opening an eye on the lookout side could be widespread, he predicts. He's seen it in a pair of birds napping side-by-side in the zoo and in a single pet bird sleeping by a mirror. The mirror-side eye closed as if the reflection were a companion and the other eye stayed open. Useful as half-sleeping might be, it's only been found in birds and such water animals as dolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning. Studies of... Question: It can be inferred that _ . Options: A: Birds never sleep with both hemispheres resting at once. B: Inner ducks depend on single-hemisphere sleep, rather than total relaxation, as often as birds napping at the end of the line do C: It is not the first time for scientists to research on birds' half-brain sleep D: Birds hardly sleep without a companion

Read the article and select the best answer. Article: Nearly 600,000 Americans lost their jobs this past month, pushing the nation's unemployment rate to 7.6 percent. But not all of those fired workers are sitting at home, reading the job advertisements and waiting for the phone to ring. Thousands of people are returning to school, making public colleges and universities among the few bright places in the disappointing US economy. At a time when many Americans have had their work hours cut or have even lost their jobs, Sherian Huddleston is working overtime. She works at Middle Tennessee State University (MTSU) where she oversees the enrollment of new students. The university's population grew by 800 students this term --an increase of 4 percent over last spring's enrollment. Huddleston says seeing the enrollment rise in a failing economy is not unexpected. "When people are out of work," she points out, "they will ask 'What else can I do?' or 'What other careers can I follow?' They will often return to school if they have not completed a degree before." Older returning students aren't the only ones increasing the enrollment at MTSU. Huddleston says she's also seeing an increase in student transfers . "Students who went out of state, or even within the state, to more expensive schools are transferring to public schools to make use of the lower cost of going to school here," she explains. Question: Which is the best title for the passage? Options: A: The Falling American Economy B: College Enrollment up in a Down Economy C: Colleges Have More Students Than Before D: Going to College Is No Longer Difficult
