1. 前半句省略，后半句是 one of which is by establishing traditional style buildings. by 在这句话里是做什么作用。
2 These kinds of buildings could foster a cultural atmosphere within which the risk of replacement of traditional culture by modern style is most likely to be reduced. 这句话是什么意思，为什么用within+ which
抱歉，第一句话是The approaches to protect a country's cultural features are various, one of which is by establishing traditional style buildings .

Answer 1

1. 根据推断，省略部分中的先行词可能是 buildings，one of which 指代其中的一座楼，因此介词 by 意思是“在...旁”，即“其中的一座楼坐落在传统样式的安居楼群旁边”。
2. 解析：
1）句子分析：
主句——These kinds of buildings could foster a cultural atmosphere 这些种类的楼房可以培育一种文化氛围
非限制性定语从句——within which the risk of replacement of traditional culture by modern style is most likely to be reduced 在这种氛围中由现代文化取代传统文化的风险特别可能被减少。
2）词语解释
within which——是“介词+关系代词”结构，which 指代主句中的 a cultural atmosphere（先行词），即 within the cultural atmosphere。
within 强调“在四周的边界限制的空间以内”，而 in 强调“在四周或两面边界限制的平面以内”，此处 within which 强调的是在空间氛围之中。

Answer 2

你真行 话说半句 然后问别人下面是什么意思？你什么意思呢？
1. 帮你猜猜吧，这里BY就是个介词而已啊，要什么作用？意思是“通过..方式”
2. which 指代 atmosphere，所以加within啊，“在这个氛围里面”

Answer 3

1.全半句作定语，by表示“以……的方式”
2.这种建筑物能培养一种文化氛围，最大可能地减少古代文化被现代风格取代的风险
within+ which=within a cultural atmosphere （which the risk of replacement of traditional culture by modern style is most likely to be reduced. 是定语从句，先行词就是cultural atmosphere ）
