词语辨析
disappoint at，disappoint by，disappoint in，disappoint of，disappoint with
【解说】disappoint后加介词at，by，in，of，with时它们之间的差别不大，一般有以下规律可循当表示“对所见所闻感到失望”时，多用at；表示“对没有达到预期目标而失望时”，多用in（of，with〕；表示“对没有得到东西而失望”，多用of；disappoint by则多用于被动结构，强调“使某人失望”，此外表示“对人失望”须用介词in；接动名词时，用at或by。试比较She was disappointed in the book.她对此书失望。She was disappointed of the book.她对没有弄到此书而失望。We were disappointed at his speech.我们对他的讲话感到失望。We were disappointed by his speech.他的讲话使我们感到失望。disappointed，disappointing
【解说】disappoint的过去分词和现在分词都可用作形容词，在句中都可用作表语。它们的区别是disappointed的意思是“感到失望的”，主语一般是人；disappointing的意思是“令人失望的”，主语一般是事或物。试比较They were disappointed at the result.他们对结果感到失望。The result was disappointing.结果是会令人失望的。disappoint，despair
【解说】
这两个词都可以表示“使失望，使绝望”，但含义及用法上有很大的区别despair是不及物动词，后面接介词of，表示“彻底失望或绝望”，口气很强，有时有“悲痛”的含义；despair of接人时，意味着厌恶和失望的感情交织在一起；disappoint是及物动词，表示“使…失望”，强调原来的希望未能实现，因而令人丧失信心，常用于系表结构中。例如It is said that when he was a boy his par-ents despaired of him.据说在很小的时候他的父母对他不抱任何希望。Although I was disappointed，I didn't des-pair.我虽失望了，但还没有绝望。下面三句意思相同
【解说】I was disappointed at not finding her at home.I was disappointed not to find her at home.I was disappointed that I did not find her at home.我对在她家没能找到她而感到失望。
