Traditional grammar requires the nominative form of the pronoun in the predicate of the verb be : 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 of It 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 in It's we. · The traditional rule creates particular problems when the pronoun following be 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 of is and the object of have. In this example, 57 percent of the Usage Panel preferred the nominative form they, 33 percent preferred the accusative them, and 10 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 hearing It 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 1we
传统语法要求系动词谓语中的代词用主格形式be ： It is I （而不是 me ）； That must be they （而不是 them ），等等。 即使现代英语有文化的人也发现很难遵守这个规则，而It is me 的烙印现在已深刻地印入了判断是否正确的准则之中， 以致很少有可能使这种用法在正式书面语中被完全接受。但是在非正式讲话中奉行传统规则已经日益变得象在卖弄学问。并且当系动词被缩减时，就象在It's we 中一样，听起来反而象是不合语法的。 当代词跟在be 后面做动词宾语或做关系从句中的介语宾语时，传统的规则就象在 当我们谈到当今“街上的犯罪”时，他们不是我们心中所想的那些人， 句中复数代词同时充当is 的宾语和 have 的宾语。 在这个例子中57%的用法使用小组更喜欢用主格形式they， 33%更喜欢用宾格形式them， 而10%则两种都接受。但是象其他的权威一样，H.W.福勒争论道，在这里用主格是一个错误，它之所以错是因为“多半听到了It is me 都被改正成 It is I 而拿不定主意，以为主格的情况在动词 to be 后面不可能错。” 作家们常常能够找到一个办法来避免这个问题：他们不是我们所想的人，我们脑子里想的是另一些人等等 参见 I1we
