There was the determination of an immigrant to gain in the new world what had been denied to him in the old, and on the part of his children an urge to throw off the immigrant onus by still more success and still more rise in a fluid and classless society.

　　问：找出这句话里的并列对象拢共分几个步骤?

　　答：第一步：找到并列连接词

　　第二步：确定连接词后的中心表达

　　第三步：根据此中心表达往前找对应的表达，即并列对象。

　　具体分析如下：

　　① 这句话有一个逗号，逗号后面是and，也就是并列连词;(第一步)

　　② and后面的on the part of his children是介词短语，不算中心表达，它修饰的是an urge。

　　③ an urge to throw off the immigrant onus是中心表达，去找前半句中与其对应的表达： the determination to gain what had been denied to him。都是名词+不定式的形式。

　　翻译：外来的移民有决心在这块新大陆上取得在旧大陆他们被剥夺的一切;而他们的孩子则渴望在这样一个没有阶级差异的自由社会取得更大的成功和进步，以此方式，来摆脱移民的身份。

　　下面来看几个TPO中的例子吧。

　　1)The total volume of water in the saturated sample must therefore be thought of as consisting of water that can, and water that cannot, drain away. (TPO1-1)

　　找并列对象：先找到并列连词and，然后看and后面的中心表达是“water that cannot”，往前找对应的表达“water that can”。

　　2)Many have been attempting to conserve water by irrigating less frequently or by switching to crops that require less water. (TPO3-2)

　　找并列对象：先找到并列连词or，然后看or后面的中心表达是“by switching to crops”，往前找对应的表达“by irrigating”。

　　3)But the myths that have grown up around the rites may continue as part of the group’s oral tradition and may even come to be acted out under conditions divorced from these rites. (TPO1-2)

　　找并列对象：先找到并列连词and，然后看and后面的中心表达是“may come to be acted out”，往前找对应的表达“may continue”。

　　总结：并列结构语法点本身并不复杂，也比较好理解，但它常常会使句子变得很长，让我们望而生畏。很多小伙伴们可能在认知上有一个误区，觉得很长的句子一定很难，其实不然，有些句子虽然长但并不难理解，只要你能读进去。
