Traditional grammar requires the nominative form of the pronoun in the predicate of the verbbe : It is I (not me ); That must be they (not them ), and so forth. Even literate speakers of Modern English have found the rule difficult to conform to,but the stigmatization ofIt is me is by now so deeply lodged among the canons of correctness that there is little likelihood that the construction will ever be entirely acceptable in formal writing.Adherence to the traditional rule in informal speech, however, has come to sound increasingly pedantic,and begins to sound absurd when the verb is contracted, as inIt`s we. · The traditional rule creates particular problems when the pronoun followingbe also functions as the object of a verb or preposition in a relative clause, as in It is not them/they that we have in mind when we talk about .crime in the streets. nowadays, where the plural pronoun serves as both the predicate ofis and the object of have. In this example, 57 percent of the Usage Panel preferred the nominative formthey, 33 percent preferred the accusativethem, and 0 percent accepted both versions.But H.W. Fowler, like other authorities, argued that the use of the nominative here is an error caused by .the temptation . . . to assume, perhaps from hearingIt is me corrected to It is I, that a subjective [nominative] case cannot be wrong after the verb to be. . Writers can usually find a way to avoid this problem: They are not the ones we have in mind, We have someone else in mind, and so on. See Usage Note at I we
傳統(tǒng)語法要求系動詞謂語中的代詞用主格形式be ： It is I （而不是 me ）； That must be they （而不是 them ），等等。 即使現(xiàn)代英語有文化的人也發(fā)現(xiàn)很難遵守這個規(guī)則，而It is me 的烙印現(xiàn)在已深刻地印入了判斷是否正確的準(zhǔn)則之中， 以致很少有可能使這種用法在正式書面語中被完全接受。但是在非正式講話中奉行傳統(tǒng)規(guī)則已經(jīng)日益變得象在賣弄學(xué)問。并且當(dāng)系動詞被縮減時，就象在It`s we 中一樣，聽起來反而象是不合語法的。 當(dāng)代詞跟在be 后面做動詞賓語或做關(guān)系從句中的介語賓語時，傳統(tǒng)的規(guī)則就象在 當(dāng)我們談到當(dāng)今.街上的犯罪.時，他們不是我們心中所想的那些人， 句中復(fù)數(shù)代詞同時充當(dāng)is 的賓語和 have 的賓語。 在這個例子中57%的用法使用小組更喜歡用主格形式they， 33%更喜歡用賓格形式them， 而0%則兩種都接受。但是象其他的權(quán)威一樣，H.W.福勒爭論道，在這里用主格是一個錯誤，它之所以錯是因為.多半聽到了It is me 都被改正成 It is I 而拿不定主意，以為主格的情況在動詞 to be 后面不可能錯。. 作家們常常能夠找到一個辦法來避免這個問題： 他們不是我們所想的人，我們腦子里想的是另一些人等等 參見 Iwe
