THE BENEFITS OF TRAVELING
I am always interested in traveling. My reasons are quite (extremely) simple and clear. If anybody is not satisfied with my viewpoint(s), I shall be greatly surprised at his ways of thinking.
In the first place, traveling increases our knowledge. Only by traveling can we see (因为用(only)开头，主动词须颠倒)things outside our home town.
In the second place, traveling is good to our health. While we are traveling, we usually exercise our bodies.
In conclusion, I earnestly hope that everybody must seize (grasp at) the opportunity of traveling.
