举个例子：As you know, in English you generally make a word pluralby adding an ‘s’ at the end. There seems to be some confusion, though, about how to make plurals of terms made up of more than one word. For example, do you say bicycles shops or bicycle shops? Do you say power of attorneys or powers of attorney?

　　如果你要表示自行车商店的复数形式，你是用“bicycles shop”还是“bicycle shops”?在表示授权书的复数时，你是说“power of attorneys”还是“powers of attorney”?

　　The answers are bicycle shops and powers of attorney.

　　正确的说法是“bicycle shops”和“powers of attorney”。

　　The rule is that you pluralise the “head” of the term.

　　名词词组复数变化的规则就是：变“重点词”。

　　The term bicycle shop is typical of most noun groups. The “head” is the last word in the group. The previous word or words actas an adjective. So the last word in the group is pluralised. Here are some more examples:

　　“自行车商店”这个名词词组是一个很典型的例子。在这个词组中，重点词是最后一个词，即商店(shop);前面的词或者词组只是起到了一个形容词的修饰作用而已。因此，在这个词组中，最后一个词变成了复数形式。更多类似的例子：

　　Bank account => Bank accounts

　　银行账户

　　Company car => Company cars

　　公司用车

　　Price limit => Price limits

　　价格限制

　　Termination notice => Termination notices

　　终止通知

　　Service charge payment => Service charge payments

　　服务费收费

　　Employee share optionscheme => Employee share option schemes

　　雇员股份认购权计划

　　However, a term like power of attorney acts rather differently. Power is the “head” and of attorney is an adjectival phrase which describes the “head”. Here are some other examples of terms that behave in the same way:

　　然而，像授权书这样的词组就又是另外一番解释了。在这个词组中，重点词是权利(power)，律师(attorney)一词只是用来充当形容词的修饰成分。更多类似的例子：

　　Article of association => Articlesof association

　　公司章程

　　Code of conduct => Codesof conduct

　　行为守则

　　Conflict of interest => Conflictsof interest

　　利益冲突

　　Course of action => Coursesof action

　　行动步骤

　　Notary public => Notariespublic

　　公证人

　　Statement of claim => Statementsof claim

　　起诉书
