单选题As a kid, Kacey Long would dream of becoming a professional woman. While studying human resources management successfully at university, Long decided to change her look. So, at 19, she decided to get her breasts enlarged, "I was all about doing anything I could to improve myself," she says. With that decision, Long joined thousands of young patients who are surgically altering their appearance each year. Teenagers even younger than Long are having breasts enlarged, noses and ears reshaped and skin changed. In 2003, almost 336,000 American teens 18 or younger had some kind of cosmetic surgery(整形美容) or procedure, a 50% increase over 2002. Patient-safety advisers believe that many of the teens having surgery are unnecessarily putting themselves at risk of injury or even death. Teens are at the greatest risk of making a decision they will regret as Long did. Long had her breasts enlarged to size D, felt sick and weak within months after the $4,500-cost plastic surgery, and had her breast fillings removed two years later. She is still suffering from the long, painful recoveries. "I wish I had never done it," says Long. She is just one of those thousands who are actually risking their future beauty by going under the knife when they are still growing.

单选题 Would it help you if you could read twice as fast as you read now? How about twenty times as fast, and with better comprehension? The human {{U}} {{U}} 1 {{/U}} {{/U}}is capable of seeing and understanding material as fast as one can turn pages, and some people do read {{U}} {{U}} 2 {{/U}} {{/U}}fast. John Stuart Mill, Theodore Roosevelt, and John F. Kennedy were all{{U}} {{U}} 3 {{/U}} {{/U}}fast readers,{{U}} {{U}} 4 {{/U}} {{/U}}have been many others. They were what{{U}} {{U}} 5 {{/U}} {{/U}}known as gifted readers; those who read very fast with excellent comprehension.

It is not ability {{U}} {{U}} 17 {{/U}} {{/U}}you lack, it is training. Because we are taught to read at 100 to 400 words per minute, we are led to believe this is our "normal rate. " But these rates are no more normal than 10 or 10000 words per minute. Improving your rate only {{U}} {{U}} 18 {{/U}} {{/U}}proper training and time.
