有朋友問我這3個詞的有什么不同摊聋，以及使用的時候語法區(qū)別麻裁。大劉在網(wǎng)上綜合找了下對應(yīng)的解釋茁裙，收集整理了下分享給大家。
詞義辨析
1瘟忱、 enough 和sufficient 在含義上幾乎沒有差異手销，指“充分的；足夠的”赫悄，表示數(shù)量完全滿足需要或期望。一般enough 比sufficient 使用更普遍埂淮。而在用法上姑隅，enough 后面既可以加可數(shù)名詞也可以加不可數(shù)名詞倔撞。如：enough people 足夠人數(shù)；enough money 足夠的金錢痪蝇。而sufficient 后面一般只能加不可數(shù)名詞。如：sufficient sunlight, water and oxygen 充足的陽光躏啰、水和氧氣趁矾；sufficient investigation 充分調(diào)查给僵。但也可以用于少數(shù)可數(shù)名詞详拙，如：sufficient funds 足夠的資金；sufficient foreign exchange reserves 足夠的外匯儲備蔓同。
2、adequate 雖然也表示“足夠的斑粱；充分的”，但是與enough 和sufficient 二詞之間有著細微差異则北。主要體現(xiàn)在以下兩點：(i) adequate 的內(nèi)涵是：合理的、公平的或不苛刻的咒锻，在主觀上并不一定是讓人滿足的守屉，有時往往指滿足一個最低或客觀標準。如：His wages are adequate to support three people. 這句話說的是：他的工資夠養(yǎng)活3個人的拇泛。即，這些錢養(yǎng)活3個人夠得上一般生活水平俺叭。但這些錢可能并不能滿足他心里的期望。 而蜈垮，He has enough money to spend. 他有足夠的錢讓他去花。 即攒发，表示他的錢完全能夠滿足他的需要晋南。 (ii) adequate 在表示“充分、足夠”時包含了“公平负间、合理、適當”的意思政溃，其并不單單指數(shù)量，更傾向于表示質(zhì)量扼鞋、標準或要求。如：adequate compensation 適當補償；adequate remedy at law 法律上的充分救濟盘寡；adequate manning 充分的船員配備；adequate disclosure 充分披露脆粥。因此在指數(shù)量上的足夠時变隔，一般用enough 或sufficient 蟹倾。
