Article: It's wonderful to go to another country, complete a volunteer project and feel that you really have a positive influence. But how can you become an international volunteer? * Plan practically. Contact the organization a few months before leaving and find out if there are materials which are rare and hard to attain for the project. What you often consider plentiful here, such as nails or hammers, is in great need in other parts of the world. * Do the project together, not on your own. You are a guest in the community. The most successful result is not that you build something and walk away, but that you and the community build something as a team. Share skills and build together. * Be flexible. Not everything is going to happen as planned. Often the other country doesn't have the right tools, manpower, transportation or funds to get all the needed work done. In a word, they lack infrastructure . * Contact with the people in the community. Often you will have "downtime" outside of the range of the project. Rather than retreat to the group with whom you traveled, be sure to spend time with the people of the community. Listen to the things about their lives. If you can't speak the language, smiles work wonders. And you will be surprised -- you will find a way to community. Volunteering is a special and life-long experience for everyone involved. Be prepared that the person who may be changed most is you. It's a joyful, often careful experience which will encourage you to view yourself, your neighbors and your world quite differently.
Answer: make good preparation in advance

Article: Washington: A research conducted at the University of Maryland looks at the numerous complex reasons as to why young children decide to include or exclude other kids from their group of friends. It suggests that the kids' decision-making process is much more complex than previously believed. "They take into account group information, ranging from cliques and networks, when deciding what makes a group work well. Sometimes kids are excluded because they lack social skills, but a lot of time it has nothing to do with that. Instead it has to do with what we refer to as 'group membership' such as gender, race, nation, and culture," says Professor Melanie Killen, the Associate Director of the Centre for Children Relationships and Culture at Maryland, who led the 4-year project. Reporting their findings in the journal, the researcher said whatever was the reason, individuals who experienced long-term exclusion from the group of friends suffered from depression, anxiety and loneliness. The study looked at two models to define how children make decisions regarding acceptance of other kids in their group -- the individual social _ model and the inter-group social cognition model. While the former says that children's rejection occurs due to social deficits like shyness, wariness or fearfulness, the latter says that it happens because of group dynamics, prejudice and exclusion. It was also found that the age of children was also a factor that influenced their decisions regarding other kids' acceptance as friends. "With age, kids become more aware of group dynamics, conventions, customs, and rituals. With this comes a greater concern about group functioning, which can lead to exclusion which can be negative from a social justice viewpoint," says Killen. The researcher believes that her study may have many benefits, as it could provide insights into how to help when children are rejected by their peers.

Article: If English means endless new words,difficult gramrnar and sometimes strange pronunciation,you are wrong.Haven't you noticed that you have become smarter since you started to learn a language? According to a new study by a British university,learning a second language can lead to an increase in your brain power,Researchers found that learning other languages changes grey matter.This is the area of the brain which processes information.It is similar to the way that exercise builds muscles. The study also found the effect is greater,the younger people learn a second language. A team led by Dr Andrea Mechelli,from University College London,took a group of Britons who only spoke English.They were compared with a goup of " _ .''who had learnt a second language before the age of five,as well as a number of later learners. Scans showed that grey matter density in the brain was greater in bilinguals than in people without a second language.But the longer a person waited before mastering a new language,the smaller the difference. "Our findings suggest that the structure of the brain is changed by the experience of learning a second language,"said the scientists. It means that the change itself increases the ability to learn. Professor Dylan Vaughan Jones of the University of Wales has researched the link between bilingualism and maths skills. ''Having two languages gives you two windows on the world and makes the brain more flexible,"he said."You are actually going beyond language and have a better understanding of different ideas." The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of 2 and 34. Reading,writing,and comprehension were all tested.The results showed,that the younger they started to learn,the better."Studying a language means you get an entrance to another world,''explained the scientists.
