As you plan -- or even go -- on your summer vacation, think about this: More and more Americans are no longer taking a few weeks off to suntan and sightsee abroad. Instead theyre working in orphanages1, building schools and teaching2 English.
假如你正謀劃怎么樣過暑假，考慮下這個：愈加多的美國人不再花數周時間去曬日光浴或者去海外觀光旅游，他們去孤兒院做義工，參與學校建設，教孩子們英語。
Its called volunteer tourism, or voluntourism, and its one of the fastest growing trends3 in travel today. More than 1.6 million volunteer tourists are spending about $2 billion each year.
這就是公益旅游，已經成為旅游界進步最飛速的趨勢之一。每年，有超越160萬志愿者游客花費大約20億USD。
