speak of sth.困难

There is no doubt that the gardens evidence an irrepressible urge to create, express, fashion, and beautify and that self-expression is a basic human urge; (46) yet when one looks at the photographs of the gardens created by the homeless, it strikes one that, for all their diversity of styles, these gardens speak of various other fundamental urges, beyond that of decoration and creative expression.

毫无疑问，这些花园证明了人们有一种难以抑制的去创造、表达、塑造和美化的冲动，而且自我表达是人类的一种基本冲动；（46）然而，当人们看到那些由无家可归者建造的花园的照片时，会突然意识到，尽管这些花园风格各异，但它们体现了装饰和创造性表达之外的其他各种基本冲动。
