The first step in planning any vacation is deciding when and where you are going. A. If you are going to a faraway place and want more quality time at your vacation destination(目的地), you may consider flying. If you enjoy the trip as much as the destination, going by train is also a good choice. B. Consider the climate at your vacation destination. Even if you travel to a warm destination, always bring at least one piece of warm clothing and a light jacket in case(以防)the temperature drops unexpectedly. C. Once you have decided where to go, the next step to decide is how to get there. This really depends on how far from home you are going and how much time you are taking. D. When you know where you are going and how you are getting there, start making all of the necessary reservations(预订). If you reserve airline tickets and hotels early, they are usually cheaper. E. Before the trip, make sure that everything is in order. Now is the time to talk to neighbors of family members about collecting your mail. The day before you leave, make sure that all of your bags are packed and that you have everything you need. 根据材料内容把以上5个段落排序,首末段已经给出。 1.______ 2._______ 3.________ 4.________ 5.________
