1.I suppose the reason is that we know all the circumstances that have occasioned them and so manage to excuse in ourselves what we cannot excuse in others.

【參考譯文】我想，其原因應該是我們知曉一切導致自己犯錯的情況，因此能夠設法諒解自己的錯誤，而別人的錯誤卻不能諒解。

【結構解析】suppose意思是“推想、料想”，"them"指上文中的“our own offenses ”，occasion在這里做動詞，是“致使,惹起,引起”的意思。

2.how scornful we are when we catch someone out telling a lie; but who can say that he has never told not one, but a hundred?

【參考譯文】當覺察到別人說謊時，我們是多么地蔑視他啊！但是，誰能夠說自從未說過謊？可能還不止一百次呢。

【結構解析】catch sb. doing sth.意思是“撞見某人做某事”。

3.For my part, I do not think I am any better or any worse than most people, but I know that if I set down every action in my life and every thought that has crossed my mind, the world would consider me a monster of depravity.

【參考譯文】至于我自己，我認為自己并不比大多數人更好或者更差，但是我知道，假如我記下我生命中每一次舉動和每一個掠過我腦海的想法的話，世界就會將我視為一個邪惡的怪物。

【結構解析】for sb's part意思是“就某人來說”，set down意思是“寫下，記下”，cross one's mind 是“無意中想到、偶然想起”，區別于經過思索才得到的想法。主語經常是 idea，thought，possiblity，比如：The thought of escape crossed my mind but immediately I dismissed it as being unrealistic. 逃跑的念頭一閃而過，但我立刻打消了這一念頭，因為太不現實。How did that fantastic idea cross your mind? 你是怎么想到那個妙計的？
