    Once upon a time, a personal diary was something you kept hidden away. It was where you wrote down your most private thoughts and feelings, knowing that no one else would read it. Then along came the Internet, and now the idea of a private diary seems old—fashioned.

    Many teenagers like writing online diaries because they feel free to write anything. “In real life, you can't always say what you think,” says Jake, an eighteen—year—old from New York. “On the Internet, you can express yourself more freely.” Fans of Jake's site log on to find out what he's been up to. What he's wearing and how he feels. He gets around two hundred letters a day from people who read his online diary.

    Some people are not sure that online diaries are a good idea. “Teenagers need to be careful with what they write on a website,” says Patricia Chadwick. “You don't know who is visiting your website and whether they will try to find you,” she says. “It's playing with fire.”

    Jake doesn't agree. “Sometimes people are a bit rude,” he says, “but I just pay no attention to them. Most of the feedback(反馈)I get is pleasant and hopeful.” He goes on, “people reading other people's diaries is nothing new. My brothers used to secretly read my diary when we were kids. The only difference is this one is seen by a lot more people!”

阅读下列短文,从每题所给的四个选项 (A 、B 、C  和 D )中,选出最佳选项。

    In an ideal world, people would not test medicines on animals. Such experiments are stressful and sometimes painful for animals, and expensive and time-consuming for people. Yet animal experimentation is still needed to help bridge vast gaps in medical knowledge. That is why there are some 50 to 100 million animals used in research around the world each year.

    Europe, on the whole, has the world's most restrictive (严格的) laws on animal experiments. Even so,its scientists use some 12 million animals a year, most of them mice and rats, for medical research. Official statistics show that just 1.1 million animals are used in research in America each year. But that is misleading. The American authorities do not think mice and rats are worth counting and, as these are the most common laboratory animals, the true figure is much higher. Japan and China have even less comprehensive (全面的) data than America.

    Now Europe is reforming the rules governing animal experiments by restricting the number of animals used in labs. Alternatives to animal testing,such as using human tissue or computer models, are now strongly recommended. In addition, sharing all research results freely should help to reduce the number of animals for scientific use. At present, scientists often share only the results of successful experiments. If their findings do not fit the hypothesis (假设) being tested, the work never sees the light of day. This practice means wasting time, money, and animals' lives in endlessly repeating the failed experiments.

    Animal experimentation has taught humanity a great deal and saved countless lives. It needs to continue,even if that means animals sometimes suffer. Europe's new measures should eventually both reduce the number of animals used in experiments and improve the way in which scientific research is conducted.
