It seems that all your friends' names on MSN have added a little green "I'm" symbol overnight. If you ask what is going on, someone will tell you it's a charity activity. Though this charity program has not yet officially begun for Chinese users, this little green symbol has proven popular among Chinese Windows Live Messenger users. Windows Live Messenger's official blog announced on March 1 that Microsoft was beginning an "I'm" program in the United States. Every time someone starts a conversation using "I'm", Microsoft shares a part of the program's advertising income with nine organizations devoted to social causes. With every instant message a user sends, it helps deal with things one feels most interested in, including poverty, child protection, disease and worsening environment. One only has to add a certain code next to one's name for the organization one would like to support. "*red'u" is for the American Red Cross, "*bgca" is for Boys & Girls Clubs of America and "*unicef" stands for the American branch of UNICEF. After a Chinese blogger named "hung" introduced this program on his blog on March 2, "I'm" entered the Internet in China with no actual support from Microsoft. Beijing-based Youth Weekend reported that famous IT blogger Keso regarded this program's rapid spread as a successful virus marketing case. He thinks that the success of the "I'm" program is because it's spread by users without being a bother to others. This answers why "I'm" has spread so rapidly across the Internet like a virus with almost no advertisement. However, Feng Jinhu from the press center for Microsoft China toldYouth Weekendthat the "I'm" project is only for Messenger users in the United States. Instant messages sent by Chinese users would not count. This has not affected Chinese Messenger users' interest in the little green symbol. These users hope their instant messages will actually contribute to charitable organizations someday. From the passage, we can come to a conclusion that _ . A) "I'm" is a computer virus that will not be easily removed B) Microsoft is active in advertising the program in China C) modern technology is being used to raise money for charity D) Chinese MSN users have no interest in the program

(Question)
Each year, about 10,000 to 100,000 animal species die off. They join the countless species that have gone extinct over the course of Earth's history - and extinction means forever. At least it used to. Scientists are now closing in on the ability to bring back extinct species. No, this doesn't mean the plot of Jurassic Park is going to become a reality. Researchers need DNA to bring back a species. DNA is the chemical that carries the structure for a living thing. Dinosaurs have been gone too long for any of their DNA to remain in fossils. But there's a very real chance that we will be able to bring back more recently extinct species. This could even include Ice Age animals like the woolly mammoth. In 2003, a team of Spanish and French scientists re-created the Pyrenean ibex, which had gone extinct three years earlier. The new animal didn't survive long, but scientific advances should improve the success rate. In January, Australian scientists announced that they were on their way to bringing back the gastric brooding frog. That we can bring species back doesn't mean that we should. There may be benefits to reviving a species. But there's no way to know how it will turn out. For example, would a passenger pigeon fit into its old habitat? Or might it crowd out existing species? Environmentalists worry that our ability to bring species back might cut down support for the hard work of traditional conservation. Why worry about preserving a wildlife habitat or fighting poachers if we know we can just make up for our mistakes? But those extinctions are our mistakes to correct, which may give us an obligation to do so. As businessman and environmentalist Stewart Brand recently said, "Humans have made a huge hole in nature. We have the ability now to repair some of that damage." We would do well to remember the lesson of Jurassic Park: Proceed with caution. What makes environmentalists worried according to the passage? A) That scientists cannot make up for the mistakes that they made in the past. B) That traditional conservation might be of no use by bringing species back. C) That scientists could lack the ability to bring back extinct species to life. D) That species that will be brought back to life will not survive long.
