Firstly, it is close to nature, in harmony with mountains and waters, and it has the environment conception of "taking mountains as the frameword and waters as the blood lineage"; Secondly, influenced by the settlement style of "the Land of Peech Blossoms", it has gradually made it a dream for the inhabitants to pursue a tranquil and lyrical village life; Thirdly, it attaches importance...

一是贴近自然、融于山水，有着以"山为骨架，水为血脉"的环境构想；二是受"世外桃源"居住模式的影响，使追求恬淡、抒情风格的村居生活逐渐成为人们的向往；三是注重血缘，聚族而居，因此礼制秩序和睦族之风表现明显。以古村落为实例的"人居文化学"研究是对当前日益兴起的"人居环境学"研究的重要补充

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
