1.By all that I have ever read, I am convinced that it is very common indeed, that human nature is particularly prone to it, and that there are very few of us who do not cherish a feeling of self-complacency on the score of some quality or other, real or imaginary. Vanity and pride are different things, though the words are often used synonymously. A person may be proud without being vain. Pride relates more to our opinion of ourselves, vanity to what we would have others think of us；

【难句解析】be prone to意思是“易于...,倾向于...”；chrish的意思是“怀有”；vanity后省略了relates，与上句对称；

【句子翻译】从我所读过的许多书看来，我相信那的确是非常普遍的一种通病，人性特别容易趋向于这方面，简直谁都不免因为自己具有了某种品质而自命不凡。虚荣与骄傲是截然不同的两件事，尽管字面上常常当作同义词用，一个人可以骄傲而不虚荣。骄傲多半不外乎我们对我们自己的估价，虚荣却牵涉到我们希望别人对我们的看法。
