关于“是几倍”和“大几倍”,也就是“X times as many as”和“X times more than”,含义相同还是不同,有两种说法。
一、剑桥词典和牛津词典是这么说的:
- She earns five times as much as I do./She earns five times more than I do. 她挣的钱是我的5倍。(剑桥词典)
- three times as long as sth 某物的三倍长
three times longer than sth 比某物长两倍
three times the length of sth 三倍于某物的长度(牛津词典)
附牛津词典截图:
可见,牛津和剑桥都认为“X times as many as”和“X times more than”含义相同,可以互换。
二、另一种看法从严格的数学定义的角度认为二者含义不同,且不可替换。如,grammarhow.com是这么说的:
