| 背面 |     释义： 1. It comes from cognitus 'known'. The word's meaning evolved via the notion of someone who 'knows' about something ("get or come to know well"), and hence is an expert at it or is skilful in doing it;2. and came to mean 'skilled, expert, clever, finely or skilfully made'; this led later to the notion of being skilfully made or elegant, which eventually degenerated into 'agreeably curious, pleasantly curious'.3. => elaborate, skillfully made; strange and clever; old-fashioned but charming.4. q -> g, => quai => guai => 怪的拼音 => 古怪啊，古怪的。adj. 有效的；运转着的；从事生产劳动的n. 侦探；技工 例句： 1. Her aggressive moods alternated with gentle or more co-operative states.她情绪多变，时而咄咄逼人，时而又显得温柔平和或乐于合作。 operative 运转的，操作的来自operate,运作，操作。 operative (adj.)"producing the intended effect," early 15c., from Old French operatif (14c.) or directly from Late Latin operativus "creative, formative," from operat-, past participle stem of operari (see operation). Weakened sense of "significant, important" is from 1955.operative (n.)"worker, operator," 1809, from operative (adj.); sense of "secret agent, spy" is first attested 1930, probably from its use by the Pinkerton Detective Agency as a title for their private detectives (1905)." |
