七、词义辨析

adj.(形容词)
necessary, essential, needful, requisite
  • 这组词都有“必要的”“必需的”意思。其区别是：
  • 1.necessary为常用词,多指总体上长期而言的需要; needful常指近期或眼下所需; essential含有缺少某一因素便不能运转、生存的意思; requisite常指某一具体任务中所需的具体东西,否则就会影响任务的完成。例如:
  • The were the instruments needful for his work.那是他工作所需要的工具。
  • We can live without clothes, but food and drink are essential to life.没有衣服我们可以生存,但是食物和水是维持生命所必不可少的。
  • Past experience is requisite for the job.过去的经验是做这工作的必要条件。
  • 2.语气上, essential比necessary强; requisite是正式用语。
  • 3.necessary和essential用在主语从句中时要用“(should+) v. ”。
    • indispensable，essential，necessary，requisite
  • 这些形容词均有“必不可少的、必需的”之意。
  • indispensable语气强，侧重指绝对必要性或不可缺少性。
  • essential指对事物本身性质具有决定性的重要性，暗含不可缺少，否则便无法存在。
  • necessary最常用词，侧重由客观因素决定的某种需要，强调不可避免，但并非绝不可缺少。
  • requisite正式用词，特指为实现某一目的或得到某种结果而应有的需要，有时可与necessary换用。
