Recently, along with my parents, I set     1    for Shangrila, a city in Yunan Province, which appeals     2     (mass) of tourists. We first went to the Potatso National Park, which stretched across vast forests, wetlands, lakes, meadows, and several remote villages. On top of its     3     (dramatic) amazing scenery, the park is also famous for its rich biological diversity. At Shudu Lake, we saw horses, cows, and yaks enjoying the sunlight and eating grass contentedly. As I have a passion for beautiful     4     (landscape), you can imagine how     5     (engage) I was in taking a look at the sight. For those who live in cities as we do, nothing is more rewarding than breathing the fresh air and     6     (hike) under this broad sky in nature.
