Since there is such an abundance of food in the sea, it is understandable that some of the efficient, highly adaptable, warm-blooded mammals that evolved on land should have returned to the sea. Those that did do that have flourished. Within about 50 million years—no time at all, geologically speaking—one of the four kinds of mammals that has returned to a marine environment has developed into the largest of all animal forms, the whale. A second kind, the seal, has produced what is probably the greatest population of large carnivorous mammals on Earth. This suggests that these “top dogs” of the ocean are prospering and multiplying. However, such has not been the case, at least not for the last 150 years. Trouble has closed in on these mammals in the form of equally warm-blooded and even more efficient and adaptable predators, humans. At sea, as on land, humans have now positioned themselves on top of the whole great pyramid of life, and they have caused serious problems for the mammals of the sea.There is a simple reason for this. Marine mammals have the misfortune to be swimming aggregates of commodities that humans want: fur, oil, and meat. Even so, they might not be so vulnerable to human depredation if they did not, like humans, reproduce so slowly. Every year humans take more than 50 million tons of fish from the oceans without critically depleting the population of any species. But the slow-breeding mammals of the sea have been all but wiped out by humans seeking to satisfy their wants and whims.1.Which of the following statements about marine mammals best expresses the main idea of the passage?2.What advantage did some land mammals gain by returning to the sea?3.It can be inferred from the passage that during the last 150 years humans have()4.Which of the following statements is supported by the passage?5.It can be inferred from the passage that marine mammals are like humans in which of the following

Using popular athletes to endorse and pitch companies and their products has become commonplace in advertising. U.S. companies paid more than $1 billion to nearly 2,000 athletes for endorsement deals and licensing rights in 1996 - a tenfold increase from just a decade ago. Nike alone spends more than $100 million a year on endorsement contracts. The average athlete on the Forbes super 40 list of top-earning athletes commands around $250,000 a year for a national endorsement. Superstar Michael Jordan, the athlete who makes the most from endorsements, considers only multiyear deals that pay at least $10 million. In addition to the endorsement fees, companies spend another $10 billion to advertise and promote their association to these athletes.While companies are investing huge sums of money into the concept that athletes make good promoter, they are also recognizing that choosing a celebrity endorser is no longer a matter of personal taste and top-management whimsy. Several companies have been badly burned when their high-priced endorsers were involved in messy scandals and controversies. Hertz Corp, used O. J. Simpson as its spokesperson for 20 years and lost all of that equity when he was accused of murdering his ex-wife and her friend. Smaller companies face even greater risks when they entrust their name and image to an athlete. When Dallas Cowboys football star Michael Irvin was caught in a motel room with strippers and drugs, 13 Toyota dealerships that paid him $120,000 to do a series of commercials had little choice but to pull the ads and swallow the $400,000 in production costs. When Irvin refused to return his payment, as well as a $50,000 car the dealerships had lent him, they sued, the case settled out of court.Risk management has become a major consideration for companies considering using athletes as endorsers. However, many marketers are willing to take chance on irreverent or rebellious athletes whose outlandish behavior draws attention to them. For example, basketball star Dennis Rodman has parlayed his bad image into endorsement contracts with Nike, McDonald's, Pizza Hut, Comfort Inn, and Converse. Rodman’s sponsors believe he appeals to the elusive Generation X market that these companies are trying to reach. However, Rodman’s antics have become too much for some companies. The Carl’s Jr. fast-food chain temporarily suspended its relationship with Rodman in early 1997 when he was suspended for kicking a courtside photographer during a game.Most companies are moving away from controversial athletes and looking for ones who will not just attract attention but enhance the image of the company or brand they are endorsing. Their goal is to achieve an endorser's halo effect - a positive association that bathes the product in good vibes after a popular sports celebrity has pitched it. Marketers have discovered that there are a number of “nice guys” available to endorse their products. Among them are tennis stars Pete Sampras and Michael Chang (who has emerged as the most popular athlete in Asia by far), San Francisco quarterback Steve Young, baseball iron man Cal Ripken Jr., Los Angeles Lakers basketball star Shaquille O’Neal, hockey star Wayne Gretzky, and golfer Tiger Woods. Even former stars with likable personalities and images as positive role models are still popular, including Arnold Palmer, Joe Montana, Jim Palmer, Nolan Ryan, and Chris Evert,Perhaps nobody embodies the new breed of nice guy superstar better than basketball star Grant Hill. An All-American at Duke, he stayed all four years and graduated with his class. His father, Calvin, played football at Yale and was a star with the Dallas Cowboys. During his first two years in the NBA, Hill received more fan votes for a spot on the NBA All-Star team than any other player, including Michael Jordan.The biggest beneficiary of Grant Hill’s nonabrasive, good-humored, All-American image has been Fila, and Italian company that signed Hill to an endorsement contract in 1994. Since signing Hill, Fila has become the third-largest sneaker maker in the Unites States. Sales shot up 37 percent in 1995 and another 40 percent in 1996 to $750 million. Hill’s namesake shoe trails only Nike’s Air Jordans in sale. Fila officials readily acknowledge that Hill’s “nice guys” image appeals to the current sensibilities of Middle American.Three years ago basketball star Charles Barkley appeared in a Nike commercial where he glowered at the camera and declared, “I am not a role model,” Since then, his endorsement take been cut in half. Hill readily acknowledges “I am a role model.” In addition to getting $6 million a year from Fila plus a 5 percent royalty on the sale of his shoes, Hill has endorse contract with Sprite, GMC trucks, Kellogg’s and McDonald’s. It appears that nice guys are finishing first in the endorsement game.1.Which of the following best states the main idea of this passage?2.According to the passage, basketball star Grant Hill has endorse contract with ()3.Based on the passage, which of the following makes the most from endorsement?4.All of the following are regarded as “Nice Guys” available to endorse the products EXCEPT ()5.Fila, an Italian company first signed Grant Hill to an endorsement contract()

Practically speaking, the artistic maturing of the cinema was the single-handed achievement of David W. Griffith (1875-1948). Before Griffith, photography in dramatic films consisted of little more than placing the actors before a stationary camera and showing them in full length as they would have appeared on stage. From the beginning of his career as a director, however, Griffith, because of his love of Victorian painting, employed composition. He conceived of the camera image as having a foreground and a rear ground, as well as the middle distance preferred by most directors. By 1910, he was using close-ups to reveal significant details of the scene or of the acting and extreme long shots to achieve a sense of spectacle and distance. His appreciation of the camera’s possibilities produced novel dramatic effects. By splitting an event into fragments and recording each from the most suitable camera position, he could significantly vary the emphasis from camera shot to camera shot.Griffith also achieved dramatic effects by means of creative editing. By juxtaposing images and varying the speed and rhythm of their presentation, he could control the dramatic intensity of the events as the story progressed. Despite the reluctance of his producers, who feared that the public would not be able to follow such a story, Griffith persisted and experimented as well with other elements which have become standard ever since.Besides developing the cinema's language, Griffith immensely broadened its range and treatment of subjects. His early movies included not only the standard comedies, melodramas, westerns, and thrillers, but also such novelties as adaptations from Browning and Tennyson, and treatment of social issues. As his success mounted, his ambitions grew. When he made a new movie in 1911, he insisted that a subject of importance could not be treated in the then conventional length of one reel. One of his movies reached the unprecedented length of four reels, or one hour’s running time. Griffith’s introduction of the American-made multi-reel picture began an immense revolution.1.The primary purpose of the passage is to()2.The author suggests that Griffith’s film innovations had a direct effect on all of the following except ()3.It can be inferred from the passage that before 1910 the normal running time of a film was ()4.It can be inferred that Griffith would be most likely to agree with which of the following statements?5.The author’s attitude toward photography in the cinema before Griffith can be best described as()
