如何确定长难句中“and”并列的成分?

如何确定长难句中“and”并列的成分?
下面几句话该怎么理解,能划分句子结构最好!
e.g.1
Sting Ray represents the first generation of programmable torpedoes and attention has been turned to the problems how to harness the vast computer powers now available with their associated software programs,how to package the maximum computer power in the smallest possible space ,and how to improve still further the processing and filtering techniques so vital to exclude extraneous noise and vibration.
e.g.2
The coming of age of the postwar baby boom and an entry of women into the male-dominated job market have limited the opportunities of teen-agers who are already questioning the heavy personal sacrifices involved in climbing Japan's rigid social ladder to good schools and jobs.
and用于并列两个词或分句,可短的还好理解,句子一长或在两个并列的词间有过多的修饰语就有的点找不着北了.希望各位大侠能帮小弟分析下,或者贴出相关的例句也可以,不甚感激!
谢谢hanlingvip的分析，可能是我还没完全说明我的问题。不知道hanlingvip介不介意把你的看句子的思路解释下。比如，对e.g.1中的attention，我第一遍读过去，感觉她好象是跟torpedoes并列，那样句子根本就没法理解了。再读第二遍，又把attention和generation并列起来。
我问我同学，他说语感太差了，但他也解释不清。不知道你能不能提供除“语感”之类以外的解释（也就是你看到这个长句的第一感觉，然后怎么样一步步分析下去的）。顺便问下，如果真的只能靠语感来感觉，那我该怎样去提高语感呢？
