阅读理解 Many families take their children on vacation. They will usually travel for a few days or weeks during school breaks. But Julie and Tim Smith planned a longer vacation with their two children. The Smith family is on a one-year trip around the world. They plan to visit 30 countries in all. Right now, the four travelers are about halfway through their trip. Ms. Smith says they are trying to see as much of the world as they can. Mr. Smith says one of the most interesting experiences of the trip has been meeting new people. He says people have been extremely friendly, very welcoming and love their kids. Eleven-year-old Tyler says he has enjoyed learning about the people they have met. He said, “I learned in Africa that people have very different lifestyles than in America.” His sister, 9-year-old Kara, discovered that she liked Thai food. Ms. Smith says that the trip teaches the children a lot. It took the family a year to prepare for the trip. They had to sell their house and cars. Ms. Smith left her job and her husband is using unpaid leave. They carry small bags filled with lightweight clothing and whatever else they need. Ms. Smith says she enjoys being able to carry everything she needs on her back. She says she does not miss the things she has back home. “What has become more important is making these memories as a family and taking those with us instead.” The Smiths will continue to head east for the next six months.
