Are you a social butterfly, or do you prefer being at the edge of a group of friends? Either way, your genes and evolution may play a major 1 , US researchers reported on Monday.

While it may come as no surprise that genes may help explain 2 some people have many friends and others have 3 , the researchers said, their findings go just a little farther than that.

"Some of the things we find are 4 uncommon," said Nicholas Christakis of Harvard University in Massachusetts, who helped 5 the study.

"We find that how interconnected your friends are 6 on your genes. Some people have four friends who know each other and some people have four friends who don't 7 each other. 8 Dick and Harry know each other depends on Tom's 9 ," Christakis said in a telephone interview.

Christakis and colleague James Fowler of the University of California San Diego are 10 known for their studies that show obesity, smoking and happiness spread in networks.

For this study, they and Christopher Dawes of UCSD used national data that 11 more than 1,000 identical(同卵的) and fraternal（异卵的） twins’ genes. Because 12 share an environment, these studies are good for showing the impact that genes have 13 various things, because identical twins 14 all their genes while fraternal twins share just half.

"We found there appears to be a genetic tendency to introduce your friends 15 each other," Christakis said.

There could be good, evolutionary reasons 16 this. People in the middle of a social network could be secret to useful gossip, 17 the location of food or good investment choices.

But they would also be at risk of catching effects from all sides -- in which case the advantage would 18 more cautious social behavior, they wrote in the Proceedings of the National Academy of Sciences.

"It may be that natural selection is 19 not just things like whether or not we can resist the common cold, but also who it is that we are going to come into 20 with," Fowler said in a statement.

The requirements for high school graduation have just changed in my community. As a result, all students must 36 sixty hours of service learning, 37 they will not receive a diploma（文凭）. 38 of service learning include cleaning up a polluted river, working in a soup kitchen, or tutoring a student. During a service experience, students must keep a journal and then write a 39 about what they have learned.

Supporters state that there are many 40 of service learning. Perhaps most importantly, students are forced to think 41 their own interests and become aware of the needs of others. Students are also able to learn real-life skills that 42 responsibility, problem-solving, and working as part of a team. Finally, students can explore possible careers 43 service learning.

For example, if a student wonders what teaching is like, he or she can choose to work in a primary school classroom a few afternoons each month. 44 there are many benefits, opponents （反对者） point out problems with the new requirement.

Second, they believe that forcing students to work without 47 goes against the law.

In my view, service learning is a great way to 48 to the community, learn new skills, and explore different careers. 49 , I don' t believe you should force people to help others – the 50 to help must come from the heart. I think the best solution is one that gives students choices. Choice encourages both freedom and responsibility.
