Article: Recently I spoke to some of my students about what they wanted to do after they graduated, and what kind of job prospects they thought they had. Given that I teach students who are training to be doctors, I was surprised to find that most thought that they would not be able to get the jobs they wanted without "outside help". "What kind of help is that?" I asked, expecting them to tell me that they would need a relative or family friend to help them out. "Surgery ", one replied. I was pretty alarmed by that response. It seems that the graduates of today are increasingly willing to go under the knife to get ahead of others when it comes to getting a job. One girl told me that she was considering surgery to increase her height. "They break your legs, put in special extending screws, and slowly expand the gap between the two ends of the bone as it regrows, you can get at least 5cm taller!" At that point, I was shocked. I am short, I can't deny that, but I don't think I would put myself through months of agony just to be a few centimeters taller. I don't even bother to wear shoes with thick soles, as I'm not trying to hide the fact that I am just not tall! It seems to me that there is a trend toward wanting "perfection", and that is an ideal that just does not exist in reality. No one is born perfect, yet magazines, TV shows and movies present images of thin, tall, beautiful people as being the norm. Advertisements for slimming aids, beauty treatments and cosmetic surgery clinics fill the pages of newspapers, further creating an idea that "perfection" is a requirement, and that it must be purchased, no matter what the cost. In my opinion, skills, rather than appearance, should determine how successful a person is in his chosen career.

Article: Charlie Bell became chief executive of McDonald's in April. Within a month doctors told him that he had color1ectal cancer. After stock market hours on November 22nd, the fast-food firm said he had resigned; it would need a third boss in under a year. Yet when the market opened, its share price barely dipped then edged higher. After all, McDonald's had, again, shown how to act swiftly and decisively in appointing a new boss. Mr. Bell himself got the top job when Jim Cantalupo died of a heart attack hours before he was due to address a convention of McDonald's franchisees . Mr. Cantalupo was a McDonald's veteran brought out of retirement in January 2003 to help remodel the firm after sales began falling because of dirty restaurants, indifferent service and growing concern about junk food. He devised a recovery plan, backed by massive marketing, and promoted Mr. Bell to chief operating officer. When Mr. Cantalupo died, a rapidly convened board confirmed Mr. Bell, a 44-year-old Australian already widely seen as his heir apparent, in the top job. The convention got its promised chief executive's address, from the firm's first non-American leader. Yet within weeks executives had to think about what to do if Mr. Bell became too ill to continue. Perhaps Mr. Bell had the same thing on his mind: he usually introduced Jim Skinner, the 60-year-old vice-chairman, to visitors as the "steady hand at the wheel". Now Mr. Skinner, an expert on the firm's overseas operations, becomes chief executive, and Mike Roberts, head of its American operations, joins the board as chief operating officer. Is Mr. Roberts now the new heir apparent? Maybe. McDonald's has brought in supposedly healthier choices such as salads and toasted sandwiches worldwide and, instead of relying for most of its growth on opening new restaurants, has turned to upgrading its 31,000 existing ones. America has done best at this; under Mr. Roberts, like-for-like sales there were up by 7. 5% in October on a year earlier. The new team's task is to keep the revitalization plan on course, especially overseas, where some American brands are said to face political hostility from consumers. This is a big challenge. Is an in-house succession(, ) the best way to tackle it? Mr. Skinner and Mr. Roberts are both company veterans, having joined in the 1970s. Some recent academic studies find that the planned succession of a new boss from within, such as Mr. Bell and now (arguably) Mr. Roberts, produces better results than looking hastily, or outside, for one. McDonald's smooth handling of its serial misfortunes at the top certainly seems to prove the point. Even so, everyone at McDonald's must be hoping that it will be a long time before the firm faces yet another such emergency.
Question: The main reason for the constant change at the top of McDonald is _ .
Options: (A) the constant change of its share price (B) the board's failure to reach an agreement (C) the falling sales (D) the physical problems of the chief executives
Asnwer: B

Article: Medicine comes in lots of different packages. Painkillers in a tablet can make your headache go away. Antibiotic cream from a tube can prevent your cuts from becoming infected. But can medicine come packaged in chicken eggs? A team of scientists from Scotland say "yes". They've engineered special chickens that lay eggs with disease-treating drugs inside. These eggs come from chickens that have been engineered to produce certain drugs inside their egg whites. These drugs are made of molecules called proteins . Animals make thousands of proteins -- they're the main element in skin, hair, milk and meat. Since animals can make proteins easily, they're good candidates for making protein drugs. Researchers have already made cows, sheep and goats produce protein drugs in their milk. But chickens are cheaper to take care of, need less room, and grow faster than these other animals. Those qualities could make chickens a better choice to become living drug factories, says Simon Lillico of the Roslin Institute near Edinburgh, Scotland. Lillico and a team of researchers changed chickens' DNA -- the code that tells cells how to make proteins -- so that the birds' cells made two protein drugs. One drug can treat skin cancer, and the other treats a nerve disease called multiple sclerosis . The scientists changed the chickens' DNA so that the birds made these drugs only in their egg whites. This protects the chickens' bodies from the drugs' possible harmful effects and makes it easy for scientists to collect the drugs.
