有趣的长难句5
上期的答案是A，小伙伴们答对了吗？有人问我，英语的长难句看着令人眼晕，为什么你觉得有趣啊？就是有趣啊，你看昨天的那道题，明明就是数学公式R=X+Y+Z，可是出题的老师故意用X、Y、Z乱搭，除了正确答案A是R=Z+X+Y之外，B答案约莫为Z=Y；C答案是R=Y；D答案R=Z。你看，套用数学公式就可以解英语题，不是很有意思吗？
今天的题选自《Architecture》一文，关于建筑的基本概念，想必大家都自有定义，万变不离其宗。它是一门关于设计结构的艺术和科学，为实用及象征的目的构建和封闭空间。而建筑之美，竭尽变幻，气象万千。今天的题目有点难，因为干扰项比较多，既有修饰句，又有同位语，就像一面墙，开了窗户挂了画，故意刁钻，撩人眼乱。
In order for the structure to achieve the size and strength necessary to meet its purpose, architecture employs methods of support that, because they are based on physical laws, have changed little since people first discovered them—even while building materials have changed dramatically.
断舍离，先砍修饰，再找准主干，来试一试吧。
