Welcome to the historic City Botanical Gardens. I'll be your guide for this morning's walk. Usually we start our tour at the Rose Garden, proceed through the Fern Valley and end at the Japanese Pavilion. However, Please note a change today. The bridge connecting the main Plaza to the Fern Valley is currently undergoing maintenance. Therefore, we will take a detour. From here, we will walk directly north.This collection passed the gift shop and loop around to the Japanese Pavilion from the back. We will unfortunately have to skip the Fern Valley today.

第 83 至 85 題參考以下導覽講解和地圖。

歡迎來到歷史悠久的城市植物園。今天早上的遊覽將由我擔任導遊。通常我們的遊覽路線是從玫瑰園開始，穿過蕨谷，最後到達日本館。但是，今天路線有所變更。連接主廣場和蕨谷的橋樑目前正在維修。因此，我們將繞道而行。從這裡，我們將直接向北走。這條路線會經過禮​​品店，然後繞到日本館的後方。很遺憾，今天我們將無法參觀蕨谷。
