　　A

　　[2016·山东诊断]For families on vacation, a playground provides a welcome break from sightseeing. It can also provide a glimpse into the local culture, from the setup of the park to the ways families interact. Here are the designs that live up to that challenge.

　　¤Fruit and Scent Park, Stockholm

　　Is there a picky eater on a steady diet of chicken fingers and cheese? Perhaps a trip to Sweden's Fruit and Scent Park will change his or her culinary (烹饪的) tune. This playground features a banana slide, an orange seesaw, pear huts, a watermelon jungle gym and a pair of cherry swings, all designed by public artist Johan Ferner Strom. Now, who can say you can't play with your food?

　　¤Nishi Rokugo Park, Tokyo

　　Located between central Tokyo and the city of Kawasaki, Nishi Rokugo combines recycled rubber tires (橡胶轮胎) with traditional playground equipment. In total， more than 3,000 tires of different sizes are used to create tunnels, bridges, tall sculptures for climbing and, of course, tire swings. There's little shade, so you can visit here in the early morning or late afternoon for the most comfortable weather, and be sure to wear your play clothes.
