Although shark attacks can seem vicious and brutal, it’’s important to remember that sharks aren’’t evil creatures constantly on the lookout for humans to attack. They are animals obeying their instincts, like all other animals. Sharks are designed to hunt and eat large amounts of meat. A shark’’s diet consists of other sea creatures — mainly fish, sea turtles, sea lions, and seals. Humans are not on the menu. In fact, humans don’’t provide enough high-fat meat for sharks, which need a lot of energy to power their large, muscular bodies. So why do they attack us In the majority of recorded attacks, the shark bites the victim, hangs on for a few seconds (possibly dragging the victim through the water or under the surface), and then lets go. The shark is simply mistaking a human for something it usually eats. Once the shark gets a taste, it realizes that this isn’’t its usual food, and it lets go. The shark’’s confusion is easier to understand once we start to look at things from the shark’’s point of view. Many attack victims are surfers. A shark swimming below sees a roughly oval shape with arms and legs dangling off, paddling along. This bears a close resemblance to a sea lion (the main prey of great white sharks) or a sea turtle (a common food for tiger sharks). Attacks have also frequently occurred when humans were spear fishing in ocean waters. Sharks are attracted to the signs given off by dying fish — the smell of blood in the water and the electrical impulses given off as the fish struggles. Sharks detect these signals with their ampullae of Lorenzini, a set of "detectors" under the skin on a shark’’s snout (嘴). Once a shark arrives on the scene, it may become agitated and aggressive. There are cases in which sharks seem to attack out of aggression, rather than hunger. Very little is known about shark behavior, but it is believed that some species, including great whites, display dominance behavior over other sharks. This behavior can take the form of "punching" with the snout, or bites that don’’t do much damage to the tough skin of a shark. Unfortunately, when a shark makes a dominance display toward a human, these "gentle" bites can still cause horrendous damage. Sometimes, the cause of a shark attack is the shark is responding to human aggression. Nurse sharks, for example, are generally placid fish that lie still along the bottom of the ocean floor. For some reason, this makes some divers think that it’’s a good idea to pull their tails. Irritated nurse sharks have taught several divers to keep their hands to themselves. In the next section, we’’ll go through a moment-by-moment breakdown of a shark attack. What is the passage going to discuss in the next section

Even as the economy improves, a jobless executive may face up to a year or more of unemployment. This is a lot of time, especially for hard-charging high-performers who are not used to having any free time. While some job seekers spend hundreds—even thousands—of hours discovering daytime television, others seem to thrive on activities that boost their professional careers or resolve family issues when they aren’’t working. Having an extended period of free time in the prime of one’’s life can in fact be a unique opportunity to focus on volunteer service, professional education or personal growth. Community Involvement For Lisa Perez, the wakeup call was burned pork chops. An executive who previously hadn’’t been particularly interested in home and health had become obsessed with homemaking during a stint of unemployment. She realized that cleaning and organizing her home wasn’’t helping her job search. Nevertheless, "I made lists of 50 things to do every day," says Ms. Perez, a political and public-relations consultant in Scottsdale, Ariz. "My house was spotless, just so I’’d have something to do." One day, her boyfriend didn’’t arrive on time for dinner because he had to work late, and her pork chops were ruined. She threw a fit. "I" d never been a person like that," she says. "So I decided to stop feeling sorry for myself, and go out and do something productive." Ms. Perez, 35, resolved to become an active volunteer for the duration of her search. She gave her time to a health-care concern, a housing program and a political campaign. The work bolstered her self-confidence. "Volunteering takes the focus off you. One thing you have that’’s still valuable is your time. And, of course, you learn that there are thousands of people with a life that’’s much worse than yours," she says. Volunteer assignments are also great ways to meet powerful and well-connected people. Over a six-month period, her volunteering evolved into working as a paid consultant and then as a full-time employee, a job she still holds today. In all, she was unemployed for eight months. Before her job loss, she thought she didn’’t have time to volunteer while working. "Now, even though I have a demanding job, I still volunteer, because of what I got out of it," says Ms. Perez. Continuing Education Gene Bellavance, a 36-year-old information-technology project manager, took another route during his unemployment. When he was laid off from a steel company near Cleveland, he knew his immediate prospects were bleak. He expected his search to take a year. He faced a decision: take a job that would set back his career or hold out for an offer he really wanted. Mr. Bellavance, single and virtually debt free, shifted his finances into survival mode. He cashed out his pension, sold his house, unloaded things he didn’’t need at garage sales, and rented an apartment with a roommate. Then, he says, "I signed up for every benefit I could find. " But he wasn’’t just waiting out the year. He spent the rest of his search updating his skills, including becoming certified in new database and project-management software. "You have to invest in yourself," Mr. Bellavance says. "I estimated what technology was going to be the most beneficial and chose applications that were going to be pervasive, that were right for my market, and that were going to ensure top pay. " In addition to income from the occasional IT-consulting assignment, he relied on a combination of displaced-worker-retraining grants and unemployment benefits. "I went out and found the classes, submitted the paperwork, and dealt with the bureaucracy. You have to stay after them, keeping your benefits moving forward. It’’s up to you to make it work with your overall transition plan," he says. His job search was one month shy of the full year he’’d expected. He looked for work during his training and says he would have finished the certification programs even if he’’d been hired before completing them. "People should not feel guilty" about accepting government aid, he says. "I saw this in a lot of people. They felt they were some kind of loser for taking benefits. My advice is: Get all you can. You’’ve been paying for these programs in your entire career, and you may as well start to benefit from them. " Family Matters In addition to pursuing training or volunteering, some displaced careerists use their time off work to attend to family matters. Many executives rediscover their children or find time to help their parents. Stanford Rappaport held three jobs in San Francisco, including high-tech and teaching positions. When he was laid off from the high-tech job last year, he knew it might be a long slog before he could get another post like it in the Bay Area. "I was able to do the math," says Mr. Rappaport, 46. "The number of people laid off: huge; and the number of available jobs: miniscule. At the time, I thought it might be two or three years before the tech industry recovered." Mr. Rappaport’’ s remaining job, a part-time faculty position with City College of San Francisco, didn’’t pay enough to support him. After a couple of months of searching with no results, he decided to escape the Northern California jobs meltdown. "My plan," he says, "was to get out of an expensive living situation, and either seek work in another section of the U.S. or overseas, for those two years. " Mr. Rappaport, who speaks five languages, had worked overseas before. Before he found an assignment, his Arkansas-based mother was diagnosed with a serious chronic illness, and he was called into duty as a son. Mr. Rappaport was able to help his mother get her affairs in order not to interrupt his search by using a San Francisco mail drop and cellphone. "I continued to look for work in California while I was in Fayetteville, Ark. , helping my mother through this crisis." He took his mother to medical appointments, made repairs on her house, bought her a better car, and straightened Cut her legal and financial affairs. "I even got to go through my father’’s effects, which in the five years since he had died were simply piled in boxes in his office, " he says. Mr. Rappaport’’s stay in Arkansas lasted six months. "It’’s amazing that at this stage I had the opportunity to spend a significant amount of time with my mother and improve her life and get a lot of things done for her. Most people never have that opportunity. I’’m very thankful that I had the chance. It was absolutely worth it," he says. One of the unexpected benefits was the huge boost in confidence he gained from his role as caregiver. He’’d been feeling depressed and defeated when he left California, but after returning, he felt renewed. He landed a job with a former employer after returning to San Francisco and remains a part-time faculty member. Discovery and Exploration Instead of spending time off lamenting your unemployed status, ask yourself: "Is there something I’’ve always wanted to do but haven’’t because of the demands of my job" Felice Fisk, a 29-year-old in Seattle, recently left an account-manager position at a contract-furniture company. During seven months of unemployment, she took an interest in fine-art painting and completed 18 pieces before returning to work. "I found the art work, or some kind of creative outlet, to be really beneficial," she says. She’’s now an interior designer for an interior-design firm. Michael Ross, 42, a former IT administrator in El Cerrito, Calif., recently spent his 10 months of unemployment playing guitar and exploring his lifelong interest in scriptwriting and the movie business. "After 18 years at my former employer and how hard I had worked, I knew I had to recover, to get restored," he says. "I looked at this as an opportunity, rather than a penalty. This was very much about clearing space for me." At the executive level, even a very efficient and successful job search may be quite lengthy. It makes sense to spend that time in an enriching and productive manner. These job seekers pursued service, continuing education and shoring up family bonds. How you’’ll look back on a period of unemployment depends on what you do with it. Lisa Perez found a new interest in homemaking during the period of unemployment.
