By May, after three months, I had lost22pounds and reached my goal of 115 pounds. My friends would say “Alice, you look great!” or “How did you lose so much weight?” Those compliments made me feel good and confident.

    Soon I dropped to110 pounds. A few of my friends told me that I needed to stop dieting, because I was starting to look sick. They brought me a present—— a bag of chocolates, which I later gave to my sister. My mother would come to my room, with tears in her eyes, and have long chats about how harmful this diet was and begged me to stop. My dad would leave worried messages on my cell phone at school, telling me that it would do serious harm to my body.

    By mid-June, when school was coming to an end, I was down to an only alive state of 95 pounds. All of a sudden, I knew I had to do something. I guessed the number itself scared me. I recalled my doctor. He told me about a girl who was 95 pounds and was at the risk of dying. I knew I was putting my life at risk, but for what? To make those who love me worried? Was it worthwhile to be thin?

    Now I realize that models in magazines, TV and movies are not realistic. The price to pay for the “perfect body” is living with a dangerous and sometimes deadly eating disorder. And there are more important things to think about than how thin you are.

    The African elephant, which is the largest land animal remaining on earth, is of great importance to African ecosystem. Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the- forest-and-savanna (大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat.

    It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and under-bushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.

    Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.

    What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.

    Visitors to Britain are sometimes surprised to learn that newspapers there have such a large circulation (发行 ). The “Daily Mirror “ and the “Daily express” both sell about four million copies everyday. British families generally buy a newspaper every morning and two or three on Sundays.

    Besides the national papers, there is, however, another branch of the British press which sells almost as many copies. Local newspapers have a weekly circulation of 13 million. Almost every town and county area has one. Nearly all of them hold their own financially (财政 ) and many of them are very profitable (赚钱的 ) .

    These papers are written almost entirely for readers interested in local events-births, weddings, deaths, council (地方会议 ) meetings and sports. Editors prefer to rely on people who know the district well. A great deal of local news is regularly supplied by clubs and churches in the neighborhood and it does not get out to date as quickly as national news.

    The editors must never forget that the success of any newspaper depends on advertising ( 广告) . He is usually anxious to keep the good will of local businessmen for this reason. But if the newspaper is well written and the news items have been carefully chosen to draw local readers, the business men are grateful for the opportunity (机会 ) to keep their products in the public eyes.

Dear Coach,

    I have been out of work for almost six months now and things are starting to get very tough for me. I am practically living out of my savings. I have been looking for a job, but things are really bad and I cannot find a single person who wants to hire me. I know that the main problem is that I do not have a degree. I want to go back to school and get my degree, but I also need a job now. I owe money to some people who have been helping me. Because I am out of work, I cannot pay them back. What do you think I should do? I need to find a job as quickly as possible, and want to know what else to do to get people to give me a chance to work for them.

The Unemployed

Dear Unemployed,

    Before you get yourself in a really bad situation, you need to stop borrowing money from people. If you continue doing that, you will be deep in debts and the situation will get even worse for you. The next thing you need to do is look for a job depending on your abilities, skills, and experience. By doing that, you will be increasing your chances of finding a job that suits you best. And the last thing I will suggest is that you should stop feeling sorry for yourself and continue working hard to get a job that you need. Borrowing money, complaining, and feeling bad for your situation will do no good to you. Stay strong and get out there and start showing the world what you can offer. I promise if you work hard and never give up, you will soon find the job that you are looking for. And while you are doing it, thing about getting your degree as well because it will help you to become more challenging. Try those tips.

    Why elephants rarely get cancer is a mystery that has confused scientists for decades. A study was led by researchers at Huntsman Cancer Institute (HCI) at the University of Utah and Arizona State University, including researchers from the Ringling Bros. Center for Elephant Conservation may have found the answer. According to the results, elephants have 38 additional modified copies of a gene (基因) that encodes p53, a well-defined tumor (肿瘤) suppressor, as compared to humans, who have only two. Further, elephants may have a more powerful mechanism for killing damaged cells that are at risk for becoming cancerous. In isolated elephant cells, this activity is doubled compared to healthy human cells, and five times that of cells from patients with Li-Fraumeni Syndrome, who have only one working copy of p53 and more than a 90 percent lifetime cancer risk in children and adults. The results suggest extra p53 could explain elephants' increased resistance to cancer.

    "Nature has already figured out how to prevent cancer. It's up to us to learn how different animals overcome the problem so we can adapt those strategies to prevent cancer in people," says co-senior author Joshua Schiffman, M.D., pediatric oncologist (肿瘤学家) at Huntsman Cancer Institute, University of Utah School of Medicine, and Primary Children's Hospital.

    According to Schiffman, elephants have long been considered a walking problem. Because they have 100 times as many cells as people, they should be 100 times more likely to have a cell slip into a cancerous state and cause the disease over their long life span of 50 to 70 years. And yet it's believed that elephants get cancer less often, a theory confirmed in this study. Analysis of a large database of elephant deaths estimates a cancer death rate of less than 5 percent compared to 11 to 25 percent in people.
