二、词义辨析:
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。
三、参考例句:

necessary evil
音标:[ˈnesəsəri]['iːv(ə)l]
necessary evil,是明知不好,但又必不可少的人或事。

Necessary,你读的是:奶sei色瑞?赶紧进来给我改了!
最近正音课上练到一个词“必要的” necessary. 很多同学都按照以前的发音习惯读成:奶sei色瑞!并且,很有可能,你也成为了被中式发音选中的孩子。但不幸的是,这种发音是不对的。更糟糕的是,由于你一直没有意识到necessary的发音错误,导致很多单词你都会跟着读错!(请一定配合上方音频学习,音频中包含necessary的美音原声示范)
Necessary丨发音剖析美式音标:[ˈnɛsǝˌsɛri]第一音节元音为:short e sound [ɛ]嘴巴微张,不滑动。(问题不大)第二音节为弱读音节元音字母e读schwa [ǝ]。不读你以为的sei,而是读[sǝ]!三四音节为重点!要记住:-ary字母组合出现在词尾时,读[ɛri],不读[ǝri]并且,-ary的读音是由[ɛr]自然滑向[i],根本不需要刻意撅嘴唇!所以,整个单词necessary的发音过程,嘴唇要一直处于放松状态,不要在-sary音节刻意撅嘴唇!
趁热打铁丨实战练习Oxygen is necessary for life.氧气对生命很有必要。
I don’t think it’s necessary.我觉得这没必要。
举一反三丨以-ary结尾常见词Dictionary [ˈdɪkʃǝnˌɛri] n.字典Legendary [ˈlɛdʒǝndˌɛri] adj.传奇的Military [ˈmɪlǝˌtɛri] n.军队 adj.军事的Secondary [ˈsɛkǝnˌdɛri] adj.第二位的;次要的Secretary [ˈsɛkrǝˌtɛri] n.秘书Visionary [ˈvɪʒǝˌnɛri] n.有远见的人Imaginary [ɪˈmædʒǝˌnɛri] adj.虚构的;想象的Extraordinary [ɪkˈstrɔrdṇˌɛri] adj.非凡的;杰出的
个人心得:学习英语,要用起自己的眼睛耳朵和嘴巴!眼睛:要敏锐观察单词拼写规律和字母组合耳朵:要作第二双眼睛,学会“观察”声音的特性嘴巴:要当录音机、复读机。把耳朵捕捉到的声音特性尽可能准确地转达还原。多听,多观察,多模仿,会让我们对音的
敏感度大幅提高,从而提高发音和听力!
'A necessary evil' 不得不接受 | 地道英语
Feifei:
大家好,我是冯菲菲。欢迎来到 BBC 英语教学的《地道英语》节目。
Rob:
And hello I'm Rob.
Feifei:
You're looking pleased with yourself, Rob.
Rob:
I am. I've just booked these dirt cheap — I mean really cheap — flights to Ibiza!
Feifei:
Wonderful!
Rob:
Look at the price — 20 pounds return! That means extra money to spend on food, drink and partying.
Feifei:
诶,让我看看。你看这儿,说票价是二十镑,你还要付燃油附加税,加起来一百多镑了。
Rob:
Er? Let me see. You're right. Grrr, I hate paying tax.
Feifei:
I guess you could say it's a necessary evil.
Rob:
Hmm, you could say that — if you mean it's something bad that can't be avoided, and you have to accept it in order to achieve a good result.
Feifei:
That's exactly what I meant, Rob. 我们可以用 "necessary evil" 来描述“不愿让其发生但又无法避免的事情”,换句话说就是“不得不接受的事情,迫不得已的事情”。因为买飞机票就必须得付燃油附加税,所以是一个 "necessary evil"。 Let's hear some examples, shall we?
Examples
For me, exams are a necessary evil — you have to do them to get a place at university.
Sitting in traffic for hours is a necessary evil if I want to drive to the seaside on a public holiday!
Oh, I hate running. But having to exercise is a necessary evil if I want to stay fit and healthy.
Feifei:
这里是 BBC 英语教学的《地道英语》节目。我们正在教给大家的英语表达是“a necessary evil 一件不想做但必须做的事情”。And, Rob, that tax on your plane ticket is unavoidable — not so cheap now, is it?
Rob:
No. Less money for eating, drinking and partying.
Feifei:
Can you get a refund? Stay at home and eat, drink and party?
Rob:
I could, but if I stayed at home, there's another necessary evil I'd have to deal with.
Feifei:
What's that?
Rob:
I'll have to spend more time with you.
Feifei:
Hmm! What time is your flight exactly?
Rob:
Well, did I say something wrong?
Feifei:
Bye.
Rob
Bye.
