“三倍于”在英语中常见的表达有 “three times as much as”、“three times the amount of” 以及 “triple that of” 等,具体使用哪个取决于语境和表达的侧重点:
用法:常用于比较两个数量的大小关系,强调前者是后者的三倍。
例句:
This year's sales are three times as much as last year's.(今年的销售额是去年的三倍。)
The cost of this project is three times as much as we initially estimated.(这个项目的成本是我们最初估算的三倍。)
用法:也用于表达数量的倍数关系,更侧重于描述数量的具体倍数。
例句:
We need to produce three times the amount of products this month compared to last month.(这个月我们需要生产的产品数量是上个月的三倍。)
The charity received three times the amount of donations this year than it did five years ago.(今年慈善机构收到的捐款数量是五年前的三倍。)
用法:“triple”在这里是动词,意为“使……成为三倍;是……的三倍” ,“that of” 用于指代前面提到的某个数量或事物,使句子结构更紧凑。
例句:
The population of this city has tripled that of ten years ago.(这座城市的人口是十年前的三倍。)
Our company's revenue this quarter has tripled that of the same quarter last year.(我们公司本季度的收入是去年同季度的三倍。)
