It took the researcher two hours less to train the supposedly smarter monkeys.
怎么去理解这里less的意思是少花2小时?
“A(基数词)+less+ B(名词)”或者"A(基数词) + B(名词)+ less"的意思都是“少了A(基数词)个 B(名词)”。例如:
One man less would be one soldier less. 少了一个男人就等于少了一个士兵。(摘自陈用仪编著的《英语常用词疑难用法手册》第2版p.485)
...twenty-six less missiles ...... 少了26枚导弹 (同上)
在网友的问题中,two hours less = two less hours
