在雅思口语考试中，描述一张照片时，你可以按照以下结构来进行高级表达：

Where it was taken/drawn（照片拍摄/绘制的地方）

When it was taken/drawn（照片拍摄/绘制的时间）

Who took/drew it（照片的拍摄者/绘制者）

Explain how you felt about it（描述你对照片的感受）

例如，如果你要描述一张你最喜欢的照片，你可以说：

"The photograph I cherish the most was taken during a trip to Paris. It was a beautiful morning, and we found ourselves in front of the Eiffel Tower. The photo captures the essence of the city's romance and history. My friend, who is an excellent photographer, took this shot. It always brings a smile to my face whenever I look at it, reminding me of the joy and wonder of that moment."

这样的描述不仅提供了照片的具体信息，还传达了你对照片的情感联系和它带给你的感受，这样的回答在雅思口语考试中通常会得到较高的评价。
