<注釋>In the upper southern United States the wordspowerful and mighty are intensives used frequently like the adverb very : Your boy`s grown powerful big.The new baby is mighty purty.Powerfulis used as an adjective in some expressions: The storm did a powerful lot of harm. In the same dialect regionthe nounpower has, in addition to its standard meaning, the sense of .a large number or amount..This sense appears in theOxford English Dictionary as common in dialectal British English of the 8th and 9th centuries: .It has done a power of work. (Charles Dickens).All these derivative senses ofpower and might take advantage of the notion of strength inherent in these nouns, making them natural intensives. Colloquial English is always on the lookout for ways to make language more vivid with new intensives.We think of the upper southern part of the United States as linguistically conservative,but in fact it has preserved uses ofpower, powerful, and mighty that were innovative in their time.
在美國中南部powerful 及 mighty 這兩個詞用作強(qiáng)調(diào)詞并與 very 一樣用得很頻繁： 你的兒子已長得很大了。新生兒非常干凈。Powerful在有些表達(dá)中還用作形容詞： 這暴風(fēng)造成巨大災(zāi)害。 在同一方言區(qū)中，名詞power 除了具有標(biāo)準(zhǔn)含義外， 還有.大的數(shù)字或數(shù)量.之意。該意義出現(xiàn)在牛津英語詞典 中， 在8世紀(jì)及9世紀(jì)的英國英語方言中使用也十分普遍： .它已做了大量工作. （查爾斯·狄更斯）。所有power 及 might 的這些衍生意義都利用兩個名詞本身力量的含義而使它們成為強(qiáng)調(diào)詞。 英語口語一直在尋求途徑以運(yùn)用新的強(qiáng)調(diào)詞，使語言變得更為生動。我們認(rèn)為美國中南部在語言的使用上是很保守的，但事實(shí)上，這部分地區(qū)卻保留了在當(dāng)時十分創(chuàng)新的power，powerful 及 mighty 的用法
