Question

The book weighs two Kg.The room measures 3 by 3.这样的测量动词是及物动词还是不及物动词,或是系动词

Answer 1

weighs 和 measures 都属于不及物动词,后门的 two Kg 和 3 by 3 都是由名词性短语作状语.
名词用作不及物动词的状语是一种英语中常见的现象,这种用法仅限于表示时间、距离、方式、各种度量等概念的名词.例如：
1、表示时间：
* Wait (a moment).稍候
* My brother called me from Shanghai (last night).我的兄弟昨晚从上海打电话给我.
2、表示距离
* I couldn't move (a step) further.我连一步也走不动了.
* John can walk (five miles an hour).约翰一小时能步行五英里.
3、表示方式
* You can do it (this way).你可以这样做.
* (All the other way),he won't agree with you.完全相反,他不会同意你的.
* Come (this way),please.请这边走.
4、表示度量
* This box weighs (five kilograms).这只箱子重五公斤.
* The room measures (five metres) across.这房间有五米宽.
