"Plants were expected to get larger with increased carbon dioxide in atmosphere, but changes in temperature, humidity and nutrient availability seem to trumped the benefits of increased carbon dioxide," said researchers from the National University of Singapore. 45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking creatures. "We do not yet know the mechanisms involved, or why some organism are getting smaller while others are unaffected," the researchers said. "Until we understand more, we could be risking negative consequences that we can't yet quantify." The change was big in coldblooded animals. Only two decades of warmer temperatures were enough to make reptiles smaller. An increase of 1 degree centigrade caused nearly a 10 percent increase in metabolism . Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growth. There is a recent report on warmer temperatures' negative effects on plankton , the base of the marine ecosystem. Warmblooded animals weren't immune from the size change caused by climate change. Many birds are now smaller. Mammals have been miniaturized too. Soay sheep are thinner. Red deer are weaker. And polar bears are smaller, compared with historical records. This is not the first time this has happened in Earth's history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a long time than the current climate change. The speed of modern climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times. So, it is likely that more negative influences of climate... Researchers from the National University of Singapore believe that _ . A) too many studies on animals' size have been done B) all the animals on the earth have become smaller C) how climate change effects animals' size has not been found clearly D) people can avoid the negative effects of climate change

(Question)
Publicity offers several benefits. There are no costs for message time or space. An ad in prime-time television may cost $250,000 to $5,000,000 or more per minute, whereas a five-minute report on a network newscast would not cost anything. Publicity reaches a mass audience within a short time and new products or company policies are widely known. Credibility about messages is high, because they are reported in independent media. A newspaper review of a movie has more believability than an ad in the same paper, because the reader associates independence with objectivity. Similarly, people are more likely to pay attention to news reports than to ads. For example, Women's Wear Daily has both fashion reports and advertisements. Readers spend time reading the stories, but they skim through the ads. Furthermore, there may be 10 commercials during a half-hour television program or hundreds of ads in a magazine. Feature stories are much fewer in number and stand out clearly. Publicity also has some significant limitations. A firm has little control over messages, their timing, their placement, or their coverage by a given medium. It may issue detailed news releases and find only portions mentioned by the media, and media have the ability to be much more critical than a firm would like. For example, in 1982, Procter & Gamble faced a massive publicity problem over the meaning of its 123-year-old company logo. To fight this negative publicity, the firm had a spokesperson appear on Good Morning America to disprove the rumor . The false rumors were temporarily put to rest. However, in 1985, publicity became so troublemaking that Procter & Gamble decided to remove the logo from its products. Which one of the following can be the best title for the passage? A) Commercial ads are more practical than publicity. B) Publicity speaks louder than ads! C) Credibility weighs more than timesaving. D) Little control over media limits publicity's credibility.

Ques: I am a good mother to three children. I have tried never to let my profession stand in the way of being a good parent. I no longer consider myself the center of the universe. I listen. I try to laugh. I am a good friend to my husband. I have tried to make marriage vows mean what they say. I am a good friend to my friends, and they to me. Without them, there would be nothing to say to you today. So here's what I wanted to tell you today: Get a life. A real life, not a desire of the next promotion , the bigger paycheck, the larger house. Get a life in which you are not alone. Find people you love, and who love you. And remember that love is not leisure , it is work. Pick up the phone. Send an e-mail. Write a letter. And realize that life is the best thing and that you have no business taking it for granted. It is so easy to waste our lives, our days, our hours, our minutes. _ . I learned to live many years ago. Something really, really bad happened to me, something that changed my life in ways that, if I had my choice, it would never have been changed at all. And what I learned from it is what, today, seems to be the hardest lesson of all. I learned to love the journey, not the destination. I learned to look at all the good in the world and try to give some of it back because I believed in it, completely and totally. And I tried to do that, in part, by telling others what I had learned. By telling them this: Read in the backyard with the sun on your face. Learn to be happy. And think of life as a deadly illness, because if you do, you will live it with joy and passion as it ought to be lived. What is the author's attitude toward work? A) Do it well to serve others. B) To earn enough money to make life better. C) Try your best to get higher position and pay. D) Don't let it affect your real life.

Last year, the management set up new rules to encourage employees to cut down on unnecessary printing fees. However, there has been a rash of abuses of the printing policy. Therefore, in order to control the cost, the management has decided to put forward more stringent regulations that are required to be followed by everyone, including the management. Starting today, the management staff will meet to discuss and begin drafting up the new policy. We will post new rules outlining the new printing policy as soon as it becomes available. Once it is completed, please read it carefully. Anyone in violation of the new rules will be considered behaving in a disorderly manner and will be punished accordingly. Your cooperation and self-discipline is highly requested. Thank you. The Management Team 2014.8.14 NEW PRINTING POLICY Effective as of 08/18/2014 Due to the fact that our costs have far exceeded our budget, we had to get to the root of the problem. Shockingly, most of our costs came from printing. A further, detailed look made us realize that too many of our 1,000 employees were wasting paper by making unnecessary copies. This, of course, has increased our paper usage, but it has also resulted in our using more of the very expensive ink cartridges as well as the repair work that has followed. Over the past month, this has occurred at a rate that is not acceptable. Therefore, the following rules will go into effect immediately starting tomorrow for everyone in all departments. This problem is serious, so anyone caught in violation of the rules below will be punished, suspended, or even dismissed. Your full cooperation is requested. (1)All departments will be assigned an access card. It will record the date and time to keep track of the number of copies your department staff makes. Managers in each department are responsible for keeping track of who uses the card by keeping a record book. (2)For bulk copies over 100, you must get advance approval from your department head. (3)Any department believed to be... What would be the worst outcome of a meeting between the manager and the general manager? A) A suspension without pay. B) Dismissal from the company. C) A pay cut. D) Being accused.
