When all the elements in a series connected by or are singular, the verb they govern is singular:
当一系列事物中由or 来连接的各项均为单数时, 其后动词也用单数形成:
Tom or Jack is coming.
汤姆或杰克要来。
Beer, ale, or wine is included in the charge.
啤酒或葡萄酒均已包括在帐单上。

(2)

When all the elements are plural, the verb is plural. When the elements do not agree in number, some grammarians have suggested that the verb be governed by the element to which it is nearer:
当所有各项均为复数形式时,动词亦采用复数形式。当事物数量不统一时,有些语法学家主张动词形式由离它最近项(的单复数形式)决定:
Tom or his sisters are coming.
汤姆或其姐妹要来。
The girls or their brother is coming.
女孩子们或其兄弟要来。
Cold symptoms or headache is the usual first sign.
感冒症状或发烧头痛通常是第一信号。

Other grammarians, however, have argued that such constructions must be avoided and that substitutes be found in which the problem of agreement does not arise:
但是,另有些语法学家却主张避免使用这种结构而使用不发生主谓不一致问题的替代结构:
Either Tom is coming or his sisters are.
不是汤姆就是她的姐妹们要来。
The usual first sign may be either cold symptoms or a headache. See Usage Note at and/or, either, neither, nor 1
