阅读下面，完成后面问题。

       ①我国的建筑，从古代宫殿到近代的一般住房，绝大部分是对称的，左边怎么样，右边也怎么样。苏州园林可绝不讲究对称，好像故意避免似的。东边有了一个亭子或者一道回廊，西边决不会来一个同样的亭子或者一道同样的回廊。这是为什么？我想，用图画来比方，对称的建筑是图案画，不是美术画，而园林是美术画，美术画要求自然之趣，是不讲究对称的。

       ②苏州园林里都有假山和池沼。假山的堆叠，可以说是一项艺术而不仅是技术。至于池沼，大多引用活水。有些园林池沼宽敞，就把池沼作为全园的中心，其他景物配合着布置。池沼里养着金鱼或各色鲤鱼，夏秋季节荷花或睡莲开放，游览者看“鱼戏莲叶间”，又是入画的一景。

        ③苏州园林栽种和修剪树木也着眼在画意。高树与低树俯仰生姿。落叶树与常绿树相间，花时不同的多种花树相间，这就一年四季不感到寂寞。没有修剪得像宝塔那样的松柏，没有阅兵式似的道旁树：因为依据中国画的审美观点看，这是不足取的。有几个园里有古老的藤萝，盘曲嶙峋的枝干就是一幅好画。开花的时候满眼的珠光宝气，使游览者感到无限的繁华和欢悦，可是没法说出来。

       ④游览苏州园林必然会注意到花墙和廊子。有墙壁隔着，有廊子界着，层次多了，景致就见得深了。可是墙壁上有砖砌的各式镂空图案，廊子大多是两边无所依傍的，实际是隔而不隔，界而未界，因而更增加了景致的深度。
