disappoint(ed)
1.disappoint是“使…失望”或“使沮丧”，不是“感觉失望”，如可以说The book has disappointed me和I have been disappointed in the book，不可说I have disappointed in the book。The book disappoints里的disappoints作“使人失望”解，是不及物动词。
2.be disappointed in...是“对于…感觉失望”，be disappointed of...是“因为得不到…而感觉失望”，比较下面两句：
- I was disappointed in the book. （我对于那本书感觉失望［那本书不及我原来所期望的好］。）
- I was disappointed of the book. （我因为得不到那本书而感觉失望。）be disappointed with...跟be disappointed in...意思相同，但后面通常接指人的词。例如：He was disappointed with his new assistant. be disappointed at...跟be disappointed in...也意思相同，后面通常接指东西的词。例如：He was disappointed at his marriage.
3.He is disappointed和He is disappointing和He despairs意思不同。参见despair 3
4.disappointed后面可以接以that引导的从句。例如：He is disappointed that he did not fulfil his quota of production last month.
5.disappointed后面可以接表示原因的不定式。例如：The teacher was disappointed to find that the boy could not spell his own name.
6.关于a disappointed look（失望的神情）等，参见much 3 (5) E
