现代社会,人类的生活条件与古人相比要舒适得多,尤其在大都市中,高楼广厦,车水马龙,歌劲舞酣,更无风霜之苦。但也正固如此,人类离自然界越来越远,与动植物也越来越淡漠,早已缺乏了亲切感。室内的观赏花木与家中的宠物鸟兽,其品种人们都不大愿细加辨别,遑论识记更多的“鸟兽草木之名” In modern society, the living conditions of human beings are much more comfortable than those of the ancients. Especially in large cities, there are high-rise buildings, busy buildings, and singing and dancing, and there is no wind and frost. But it is also true that human beings are getting farther and farther from the natural world, and animals and plants are becoming less and less indifferent, and they have long lacked a sense of intimacy. The indoor ornamental plants and the pets, animals and animals in their homes are not very likely to be distinguished by the species, and the public will know more about the name of birds and animals.
