- 词义辨析
essential, necessary, needful, requisite
这组词都有“必要的”“必需的”意思。它们的区别是: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. ”。

谐音记忆法1
谐音:也想瘦。
联想:为啥你也想瘦,因为再不瘦就没人要啦!所以就引申出【也想瘦=essential】是【很有必要】的,不然你怎么会说你也想瘦。
再由必要的,必须的。再引申为名词:必需品。
