It is not just the availability of the goods that is the problem, but the speed with which new types of products come on the market. Advances in design and production help quicken the process. Products also need to have  a short lifespan so that the public can be persuaded to replace them within a short time. The typical example is computers, which are almost out­of­date once they are bought. This indeed makes selection a problem. Gone are the days when one could just walk with ease into a shop and buy one thing; no choice, no anxiety.

体裁：议论文　题材：介绍说明　主题：选择并非一种权利

【语篇解读】　本文是一篇议论文，当今社会，很多人误以为选择是自己拥有的一项权利。其实，在很多情况下，那只是一种幻觉，不过是被一些公司或广告商为了出售他们的产品而营造的一种错误想法。

【难句分析】　And for those who think they are exercising their rights to make choices, the whole system is merely an illusion, a false idea created by companies and advertisers, hoping to sell their products.

分析：本句是一个复合句，for those who think they are exercising their rights to make choices 是介词短语在句子中作状语，其中who think they are exercising their rights to make choices是定语从句，修饰前面的those；主句部分为the whole system is merely an illusion, 句型为：主语＋系动词＋表语；a false idea created by companies and advertisers... products为同位语，其中created by companies and advertisers为后置定语，hoping to sell their products 为伴随状语。
