The effect is altogether lighter and freer than that achieved in stone, but because both perform the same function, formal wooden and metal statues still display frontality.
【句子主干】
The effect is altogether lighter and freer than that achieved in stone (but…) formal wooden and metal statues still display frontality.
【结构分析】
1) but前后链接的两个句子从语法上讲都是主句;另外要注意表示让步和转折的词汇在同一个句子中只能出现一次，所以本句中只出现了but，前面表示让步的单词(although、while等词)要省略，但是翻译的时候要翻译出来
2) 一上来的这个句子是个比较句式，在比较句式中若出现两次被对比的单词，(就像这里比较的是effect)，后面再提到的时候就用that来代替，可以避免重复，使得句子读起来朗朗上口
3) because引导的是原因状语从句，后面的句子才是主语
【重点词汇】
perform – 执行 完成 表演
function – 功能
formal – 正式的
display – 陈列 展示
【句子翻译】
(尽管)这个效果总的来说比用石头所呈现的效果要更加轻快自由，但是因为两者都履行相同的功能，所以比较正式一点的木制和金属雕塑依然展现了正面描绘的手法。
