单项选择题
For years, millions of Americans and people from around the world have crowded into the well-known major parks. They have read the travel literature or heard firsthand reports about these wonders, and naturally they’ve had to see for themselves.
At times, visiting some of our parks has become more like rubbing elbows at a jam-packed Major League baseball game than sensing the solitude of the wilderness. We have tried to see the most and the best in the least amount of time. We have jumped into cars and campers and rushed off to cover a dozen parks in a week or two-madly snapping photographs as we go.
A．they like the well-known major parks
B．they want to gain the same knowledge as others
C．they want to show the pictures of those parks to their friends
D．they don’t care for line historic parks
