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,剛好與事實或標(biāo)準(zhǔn)相符,強調(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…方面準(zhǔn)確〔嚴(yán)謹(jǐn)〕”。
- exact無比較級和最高級形式。
- exact的基本意思是“要求”“索取”,一般指“硬性要求”“強求”。
- exact只用作及物動詞,接名詞作賓語。常與介詞from連用,表示“向(某人)征收〔索取〕…”“迫使(某人)處于某種狀態(tài)”。
