Travel is a good teacher
General speaking, everyone likes traveling. Travel is the best teacher of us, because we can learn a lot from it.
For example, last summer I went to . It has a great landscape, but the most important thing is that I learn a great many knowledge about national parks. Smoky, which is an example, is a cute cub who taught us not to fire the forest. And the burned forest can witness all. The hot spring taught us about terrestrial heat which is under the earth’s crust, formed by a lot of lava. The Old Faithful Geyser is one of those.
As these cases stand, travel is the best teacher. We can know more than just reading books because we touched it. We saw it. We felt it just in front of us. As the saying goes, the real thing always has more persuasiveness that the book.不懂的继续提问哈
