应该要有are. A is as + 形容词 + as B 的句型表示的是A和B的程度一样,A和B既可以是单词,也可以是句子,但必须是单词对单词,句子对句子而这里比较的是两句话:The atmosphere is a part of the earth.The earth's (its) soil and the water of its lakes,rivers are a part of the earth.即:The atmosphere is a part of the earth as much as its soil and the water of its lakes,rivers are a part of the earth. 为了句子结构的平衡,省略重复的部分,调整部分词序,形成本句的结构,而are是B这个句子的谓语动词,是不能省略的.
