这是牛津词典例句。
为何可以说travel first class ? 怎么样理解和翻译呢？travel first class, travel是及物动词，first class作宾语，的意思是呢？不可以理解。
first class 为合成词，可以是名词和副词。first-class为形容词。
带连字符的first-class用在名词前作前置定语，词典将它网站收录为形容词。但《韦氏高阶》觉得first-class也可以是副词。
《牛津》和《朗文》觉得带连字符的为形容词，空格为名词和副词。
作状语时的first class在《牛津》和《朗文》被剖析为副词。用在名词地方上的first class被剖析为名词。
所以， travel first class 被这二部词典根据副词作状语剖析。
