5. The question of when to use nominative forms of the personal pronouns (for example, I, she, they ) and when to use objective forms (for example, me, her, them ) has always created controversy among grammarians and uncertainty among speakers and writers. There is no problem when the pronoun stands alone in combination with a single verb or preposition: every native speaker says I (not me ) read the book; They told him (not he ); The company bought a computer for us (not we ); and so forth. But the decision is more problematic in other environments. · When pronouns are joined with other nouns or pronouns by and or or, there is a widespread tendency to use the objective form even when the phrase is the subject of the sentence: Robert and her are not speaking to each other. This usage is natural in colloquial speech, but the nominative forms should be used in formal speech and writing: John and she (not her ) will be giving the talk. · When pronouns joined by a conjunction occur as the object of a prepositionsuch as between, according to, or like, many people use the nominative form where the traditional grammatical rule would require the objective; they say between you and I rather than between you and me, and so forth. Many critics have seen this construction as originating in a hypercorrection, whereby speakers who have been taught to say It is I instead of It is me come further to assume that correctness also requires between you and I in place of between you and me. This explanation of the tendency cannot be the whole story, in as much as the phrase between you and I occurs in Shakespeare, centuries before the prescriptive rules requiring It is I and the like were formulated. But the between you and I construction is nonetheless widely regarded as a marker of grammatical ignorance and is best avoided. · In other contexts the traditional insistence that the nominative form be used is more difficult to defend. The objective form sounds most natural when the pronoun is not grammatically related to an accompanying verb or preposition. Thus, in response to the question “Who cut down the cherry tree?” we more colloquially say “Me,” even though some grammarians have argued that I must be correct here by analogy to the form “I did”; and few speakers would accept that the sentence What, me worry? is improved if it is changed to What, I worry? The prescriptive insistence that the nominative be used in such a construction is grammatically questionableand is apt to lead to almost comical pedantries. · There is also a widespread tendency to use the objective form when a pronoun is used as a subject together with a noun in apposition, as in Us engineers were left without any technical support. In formal speech or writing the nominative we would be preferable here. But when the pronoun itself appears in apposition to a subject noun phrase, the use of nominative may sound pedantic in a sentence such as The remaining members of the admissions committee, namely we, will have to meet on another day. A writer who is uncomfortable about using the objective us here would be best advised to rewrite the sentence to avoid the difficulty.See Usage Note at be, but, we
关于什么时候用人称代词的主格形式（比如，I,she,they )以及什么时候用宾格形式（比如， me ,her, them )的问题在语法专家们之间造成了争议， 在说话者和作者之间引起不确定。当一个代词单独与一个动词或单词组合时没有问题：每个以英语为本语的人都说I （不是 me ) read the book; They told him （不是 he ); The company bought a computer for us （不是 we );诸如此类。 但是在其他环境里这种决定更有问题。当代词和其他名词或代词用and 或 or 连接起来时， 甚至词组在句子中做主语时使用宾格形式也会有很广泛的趋势：Robert and her are not speaking to each other 。 这种用法在口语中常见，但在正式的演讲或写作中应用主格形式：John and she （而不是 her ) will be giving the talk 。 当代词和一个连接词正好成为介词的宾语时，比如between,according to, 或 like 的宾语的时候， 许多人会在传统语法规则认为用宾格的地方用主格。他们说between you and I , 而不是between you and me ,如此等等。 许多评论家们已经把这种结构看成是起源于矫枉过正，因此那些被教说It is I 而不是 It is me 的人更进一步认定如要矫正需说 between you and I ， 而不是between you and me 。 这样解释还不彻底，因为词组between you and me 在莎士比亚作品中就出现过， 那还是在要求It is I 这种既定规则和类似形式得以明确的几个世纪以前。 但是结构between you and I 反而被广泛认为是语法上无知的罪魅祸首， 从而应该避免。在其他的上下文中要用主格形式的主张更难维护了。当代词语法上不与一个助动词或介词联系时其宾格形式听起来更自然。因此，在回答“Who cut down the cherry tree?” 时我们更口语化回答 “Me” ， 尽管有些语法专家们辩论说就象形式“I did” 一样， I 在这种情况下是对的； 几乎没有一个人会接受如将What, me worry? 改成 What, I worry? 原句会更好一些。 认为在这样的结构里要用主格的规定在语法上令人质疑的，而且容易导致可笑的迂腐。当一个代词与一个名词是同位语时且此代词为主语时，也有一种广泛的用宾格的趋向。比如在Us engineers were left without any technical support 。 在正式的讲话或书写中主格we 更合适。 但是当一个代词与另一个做主语的名词词组是同位语时，便用主格形式看起来学究气。比如在句子The remaining members of the admissions committee, namely we, will have to meet on another day。 一个如果对用宾格us 感到不舒服的作家， 最好建议他重写这个句子来避免这个困难参见 be， but， we
