New Zealand is one of the best places in the world for outdoor sports.A verypopular sport there is
‘tramping’ (徒步旅行), the New Zealand way of hiking. The country has many beautiful national parks with wonderful scenery (风景). You can tramp there for a day or two, even a week. It’s also a great place for skiing. Because it’s in the south, you can ski from June to October, when the rest of the world is in summer. On your vacation in New Zealand, you can ride horses, go diving, climb mountains or do a parachute-jump (跳伞) from an airplane. You can also ride a jet boat (喷射艇). It can travel at almost 1000 kilometers per hour!
