课时达标作业(十六) Section Ⅰ　Reading and Thinking — Comprehending Ⅰ. 阅读理解 A With its snow­covered mountains and a variety of wildlife, Yellowstone National Park is one of the scenic treasures of the United States. Located primarily in Wyoming, the park hosts millions of visitors every year. If you plan to travel within the park, keep in mind the advice from the National Park Service. Seasonal Travel Travel varies vastly from season to season. Roads are generally open in the summer except for cases of rock or mud slides, wild fires, accidents or road construction.

Allow yourself at least two days to fully travel the loop due to the size of the park and occasionally heavy traffic. Safety Awareness Buffaloes often block the roads in the park as they migrate through the fields. If a herd is travelling across the road you are on, you can either wait for them to pass or find an alternative route.
