| 词组 | certain |
| 释义 | 1．a certain man, certain persons, a certain Mr Carr 等表达方式里的 certain 作“某”解，是形容词。certain of his friends 里的 certain 作“某某若干”解，是名词或代词，属于复数，不可说 a certain of his friends，该说 a certain friend of his。 2．a certain hesitation, a certain coldness 等表达方式里的 a certain 作“一些”解。注意 hesitation 和 coldness 都是抽象名词。 3．certain 和 sure 有若干相似的地方，但 certain 比 sure 语气重些。两个单词后面都可以接 of、不定式或以 that 引导的从句，如 I am certain (或 sure) of his honesty, I am certain (或 sure) to see him tomorrow 和 I am certain (或 sure) that he is honest。但 It is certain that ...比 It is sure that ...普通得多。 4．He is certain (或 sure) to come tomorrow 是“他明天一定来”。He is certain (或 sure) of coming tomorrow 是“他相信他明天一定来”。可以说 It is certain (或 sure) to be fine tomorrow，不可说 It is certain of being fine tomorrow。 5．I am not certain (about) where he lives 里的 about 可有可无。 |
