Travel is useful to us in at least three ways.
First, by 1 we can enjoy the beautiful scenery(风景) of different places. We can see 2 our own eyes many which can be read about in books, and 3 some famous cities and scenic spots.
4 , we will meet people with different interests and see strange and different things when we travel. We can get ideas of the conditions and customs of 5 people, taste different foods and local favors(偏爱) if we like 6 this way, we can understand how different other people live.
Third, travel will not only help us gain(获得) 7 of geography and history and other knowledge, 8 will also help us keep healthy and make us less narrow minded(才智有限的)。
