【Covering almost 29 square kilometers 状语】,【the zone主语】 【will be created被动式谓语】 【modeled (=which/that is modeled“ 以什么为模型 ”)on existing free trade businesses in the country's econ...基本理解，不过感觉楼下那位朋友说的含有倒装很有道理，貌似是主语后置定语有点长吧，因此把谓语be和表语created就先提前了...the zone（that is modeled on existing free trade businesses in the country's economic hub）will be created.这样理解是不是好点这样理解看起来是容易，但是，严格按照语法来讲，这不叫【倒装】，因为，倒装重点是指【主语和谓语倒装】。而你的说法倒是很正确的理过去分词作定语，但定语过长,因此，将谓语提前，使句子主体结构首先明确，而将定语后置。这个在高中教材中很明确叫做【过去分词（或过去分词短语）做后置定语】，一般可以替换为【定语从句或并列结构】。教材原句举例：The teacher is a very enthusiastic woman【 called Ms Shen】.辅导资料例句：I was impressed with the efficiency of the work 【done in thecompany】. 你所给的原句可以变换理解为：Covering almost 29 square kilometers，the zone will be created modeled on existing free trade businesses in the country's economic hub.=Covering almost 29 square kilometers，the zone 【modeled on existing free trade businesses in the country's economic hub 】will be created .=Covering almost 29 square kilometers，the zone 【which/that is modeled on existing free trade businesses in the country's economic hub 】will be created .=Covering almost 29 square kilometers，the zone will be created 【and it ismodeled on existing free trade businesses in the country's economic hub 】
