原文：
The plan I conceived was architectural and based on the elements of the domestic settlement: hearth, wall, terrace, roof. A fifth main division should comprise the working together of these four elements and embrace high art and, in a symbolic sense, high science. This plan should make apparent the derivation of objects and forms from their primordial motives and style changes conditioned by circumstances.

參考答案：

我設想的計劃是關于建筑的，并且基于國內住宅要素：壁爐、墻壁、露臺和屋頂。第五種要素應該包括與上述四種要素相關的方面，其中包括高級藝術，并且以一種象征性來看，也應該包括高科技。這一計劃應該能夠清楚地表明物品的來歷、源于物品原始用途的形式，以及由環境造成的物品風格變化。

本期句子結構分析：
1、A fifth main division should comprise the working（注意哦？comprise the working是一個意群，而不是working together在一起） together of these four elements and embrace high art and, in a symbolic sense, high science.

2、This plan should make apparent（使得...變得清晰，后面三個AND都是說要變得清晰的那個東西） the derivation of objects and forms from their primordial motives and style changes conditioned by circumstances.
