有些人因疾病而死,而这些疾病是可以被治愈的,但是他们没有最好的药物,有些药甚至并不是很昂贵,但是他们实在生活太困窘了

So, if you bought a newspaper it would be only two sheets because it was so expensive-- not all the thick paper that we have today-- and it would cost something like $10 or $20 in today's prices.

你要是在当时买报纸的话,恐怕只有两页纸,因为纸实在是太贵了-,而且我们现在用的那种厚纸很少见-,按照今天的物价水平,大概需要10至20美元。
