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。

译文：对那些认为在行使他们的权利作出选择的人来说，这一整个制度不过是一个幻觉，它是由一些公司和广告商希望出售他们的产品而营造出来的错误想法。

1．What does the author try to argue in the first paragraph?

A．The practice of choice is difficult.

B．Choice is a born right.

C．It's easy to make choices.

D．Companies offer good shopping choice.

解析：A　考查细节理解。根据第一段中的“But for a good many people in the world, in rich and poor countries, choice is a luxury, something wonderful but hard to get, not a right.”可知，作者认为对世界上的很多人来说，选择并非是一种权利，无论是在贫穷的国家还是在富有的国家中，选择对他们来说其实是一种奢侈品，很美好但很难得到。也就是说选择是很难做到的，故选A项。
