| 词组 | occasion |
| 释义 | 1．occasion 前面用 on。例如：I met some strangers on that occasion. 2．on occasion 作“偶尔地”解。例如：I call on him on occasion.注意不用复数形式 occasions。 3．have occasion to...（不定式）作“有……的必要”解。例如：I had occasion to spend a night at a temple some years ago.下面几点该注意： （1）这种用法不作“有……的机会”解。 （2）occasion 前面没有 an 或 the。 （3）说“没有……的必要”可以说 have no occasion to..., have little occasion to...或not have any occasion to...。例如：I have no（或little）occasion to see him these days.和 I do not have any occasion to see him these days. 比较下面两句： I have no occasion to see him.（我不必要看见他。） I have no opportunity（或 chance）to see（或 of seeing）him.（我没有机会看见他。） I have no occasion of seeing him 是不成立的。 4．take occasion to...（不定式）作“趁着机会而……”解。例如：I took occasion to tell him about my work.下面两点该注意： （1）occasion 前面没有 an 或 the。 （2）“不趁着机会而……”该说not take occasion to...，不可说 take no occasion to...或 take little occasion to...或not take any occasion to...，如可以说 I did not take occasion to tell him about my work，不可说 I took no（或little）occasion to tell him about my work 或 I did not take any occasion to tell him about my work。 5．occasion 用作动词可以有双宾语。例如：His long silence occasions me great anxiety.但现在用 occasion 不及用 cause 普通。 |
