用法辨析
- exact作形容詞是“準(zhǔn)確的,確切的,精確的”的意思,指數(shù)量、品質(zhì)等不多不少,剛好與事實(shí)或標(biāo)準(zhǔn)相符,強(qiáng)調(diào)絲毫不差。exact引申還可作“嚴(yán)謹(jǐn)?shù)?嚴(yán)格的”解,一般指的是人做事時(shí)嚴(yán)謹(jǐn)?shù)膽B(tài)度。
- exact在句中用作定語或表語。與in連用,表示“在…方麪準(zhǔn)確〔嚴(yán)謹(jǐn)〕”。
- exact無比較級(jí)和最高級(jí)形式。
- exact的基本意思是“要求”“索取”,一般指“硬性要求”“強(qiáng)求”。
- exact衹用作及物動(dòng)詞,接名詞作賓語。常與介詞from連用,表示“曏(某人)征收〔索取〕…”“迫使(某人)処於某種狀態(tài)”。
adj. (形容詞)
v. (動(dòng)詞)
