From the moment that an animal is born it has to make decisions. It has to decide which of the things around it are for eating, and which are to be avoided; when to attack and when to run away. The animal is, in fact, playing a very dangerous game with its environment, a game in which it must make decisions- a matter of life or death.

Animals’ ability to act reasonably is believed to come partly from what we may call “genetic(遗传性的)learning”, which is different from the individual(个体的)learning that an animal does in the course of its own lifetime. Genetic learning is learning by a species-animals of the same kind-as a whole and it is achieved by selection of those members of each generation that happen to act in the right way. However, the role of genetic learning depends upon how similar the future environment is to the past. The more important individual experience is likely to be, the less important is genetic learning as a means of getting over the problems of the survival game. Because most animals live in ever changing environments from one generation to the next, it is not surprising to find that very few species indeed depend wholly upon genetic learning.

In the great majority of animals, their particular ways of acting in a new environment are a compound(复合体)of individual experience added to the action patterns animals are born with. That is why animals can survive.

“S. H. E. is going to sing at the CCTV annual Spring Festival Evening Party, is that true?” cried out Peng Weiye, a Senior 2 girl in Shanghai and die-hard(铁杆的)S. H. E. fan.

After checking it on the Internet, Peng quickly phoned friends to spread the news. For fans like her, S. H. E. ’s performance is perhaps the only part of the old fashioned evening to get excited about.

The Taiwanese band is made up of Selina, Hebe and Ella. Their name comes from the first letter of each of the singers’ English names.

Last week S. H. E. announced they will perform in Las Vegas, US, over Christmas and then in Guangzhou on January 15.

At their Shanghai show on October 30, hundreds of parents waited outside the Hongkou Stadium. Thousands of teenagers sang, cried and shouted as the band performed.

“I love their music, healthy image and everything related to them. Thank God that, although my parents don’t understand why I love them so much, they still bought me a ticket for that show,” said Peng about the Shanghai performance.

It is not just on the mainland that the three girls have thrilled(make sb. excited)audiences. In the past year the band has passed through Taiwan, Hong Kong and even Singapore and Malaysia.

When the three high school girls entered a singing contest in Taiwan in 2000, none of them ever dreamed of being a superstar. “We had never met before, and we didn’t talk at all at the beginning,” recalled Ella.

When asked about the secret of their success, she said, “Our average looks and not-so-expensive clothes keep us close to our fans. We are happy to be the girl next door, your singing sisters. ”

“It’s really a magical journey, from day- dreaming high school girls to singers performing on the same stage as our idols. Nothing but magical,” she said.
