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(联系) the organization a few months before leaving and find out if there are materials which are rare and hard to get 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(社区). The most successful result is not that you build something and walk away, but that you and 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(基础设施).
* Contact the people in the community. Often you will have “downtime” outside the range of the project. Rather than move back 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(参与的). 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.

If doctors want to test you for something, they’ll usually take a blood or urine sample. But wouldn’t it be much more convenient if they just asked you to breathe through a special instrument?In fact, your breath can say a lot about you. In traditional Chinese medicine, doctors draw a conclusion about the health state of a patient based on the smell of his or her breath; trained dogs and rats can identify the smells of the breaths of people suffering from certain cancers; traffic police also monitor drivers’ alcohol consumption by testing their breaths.
Just like blood and urine, your breath contains lots of “metabolites” —the waste chemicals that the body produces, which vary from person to person. They are like personal health fingerprints, which is why scientists sometimes call them “breathprints”, according to Science Daily.
Compared to blood or urine testing, breath testing takes only seconds instead of hours, and it requires neither a needle nor a container to hold the body fluids(液). This means the test can be taken frequently to better detect early signs of diseases and monitor the progress of a medical treatment.
On the other hand, as an identifier, you might think that breaths are not as reliable as fingerprints since they might change based on what you eat. However, researchers in Zurich, Switzerland mapped 11 healthy volunteers’ chemical patterns by having them breathe through a special instrument, and they found that each pattern was unique and the patterns didn’t change much throughout the day, reported BBC.
“Our goal is to develop breath analysis to the point where it becomes competitive with the established(早已确立的)analysis of blood and urine,” said Malcolm Kohler, professor at the University Hospital Zurich.
