When prehistoric man arrived in new parts of the world, something strong happened to the large animals; they suddenly became extinct. Smaller species survived; the large, slow-growing animals were easy game, and were quickly hunted to extinction. Now something similar could be happening in the oceans. That the seas are being over-fished has been known for years and researchers such as Ransom Myers and Boris Worm have shown how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) inanes fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then. Dr. Worm acknowledges that these figures are conservative . One reason for this is that fishing technology has improved. Today's vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around noise. Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the date support an idea current among marine... Dr Myers and other researchers hold that _ . A) people should look for a baseline that can't work for a longer time B) fisheries should keep the yield below 50% of the biomass C) the ocean biomass should restore its original level. D) people should adjust the fishing baseline to changing situation.

After studying the daily habits of 177 self-made millionaires over the course of five years, Thomas C. Corley found that they avoid one costly habit: procrastination . "It prevents even the most talented individuals from realizing success in life," he writes in his upcoming book, "Change Your Habits, Change Your Life." This goes hand-in-hand with author Napoleon Hill's claim that the wealthiest people are also the most decisive people. Out of the 500 millionaires Hill studied in the early 20thcentury, "Every one of them had the habit of reaching decisions quickly," Hill wrote in his 1937 classic, "Think and Grow Rich." One of the major causes of procrastination is lack of passion, Corley emphasizes: "We simply like to do the things we like to do and we put off the things we do not like to do." "According to Gallup, only 13% of employees are 'engaged' in their jobs, or emotionally invested in their work," Corley writes. "Whether you realize it or not, procrastination is a big reason why you are struggling financially in life. It damages your credibility with employers and fellow colleagues at work. It also affects the quality of your work and this affects the business you or your employer receive from customers, clients, and business relationships." The good news is that anyone can overcome procrastination -- and it's simpler than you may think. He also notes that "the voice of procrastination screams just as loud and clear in the minds of those who _ in life as it does in the minds of those who do not." How do they silence it? They rely on "to-do" lists to get things done. They create firm deadlines, and they meet with "accountability partners" to ensure they're sticking to their goals and deadlines, Corley says. Nearly everyone is susceptible to procrastination -- but fighting against it can make all the difference. What might be the best title for the passage? A) Fighting procrastination B) How to become a millionaire C) Research on a bad habit D) The importance of making "to-do" lists

Ques:Thanks to the Internet, a whole new online world has been opened up for us to meet, chat and go where we've never been before. But just as in face to face communication, there are some rules of behavior that should be followed when on line. The basic rule is simple: treat others in the same way you would want to be treated. Imagine how you'd feel if you were in the other person's shoes. For anything you're about to send: ask yourself, "Would I say this to the person's face?" if the answer is no, rewrite and reread. Repeat the process till you feel sure that you'd feel comfortable saying words to a person's face. If someone in the chat room is rude to you, your instinct is to fire back in the same manner. But try not to do so. Just pay no attention to it, or block his message. If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room. Everyone was new to the network once. Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it's a stupid question or an unnecessarily long answer, be kind about it. If it's a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn't give you license to correct everyone else. If you do decide to tell someone about a mistake, point it out politely At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended. It is not polite to ask others personal questions such as their age, sex and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don't ask such questions. When you send short messages to a person, you must _ . A) make sure they mean no harm B) read them again and again C) say something good to hear D) repeat them later to his face
