"make an estimate of" 是一个动词短语,核心含义是“对……作出估计/估算”,强调“主动进行估算”的动作,通常用于需要量化或评估某事物(如成本、数量、时间、损失等)的场景。
字面直译是“对……做一个估计”,实际表达“通过分析或判断,大致计算/评估某事物的规模、数量、价值等”。
短语的结构是 "make an estimate of + 名词/代词/宾语从句",其中:
"of" 后面接被估算的对象(即“估算的内容”);
可通过添加形容词(如 rough/detailed/conservative 等)修饰 "estimate",细化估算的性质。
表示对具体事物的估算:
We need to make an estimate of the cost before starting the renovation.
(我们需要在装修前估算成本。)
The scientist made an estimate of the population of endangered birds.
(科学家估算了濒危鸟类的数量。)
Can you make a rough estimate of how many guests will come?
(你能粗略估计一下会来多少客人吗?)
The contractor made a detailed estimate of the construction expenses.
(承包商对施工费用做了详细估算。)
当被估算的内容是“某个情况/数值”时,可用从句补充:
She made an estimate of what the trip would cost.
(她估算了这次旅行的费用。)
The team made an estimate of how long the project would take.
(团队估算了项目需要的时间。)
若强调“估算由谁作出”,可转换为被动:
An estimate of the flood damage was made by the local government.
(当地政府对洪水损失作出了估算。)
"estimate" 本身可作动词(直接接宾语),与 "make an estimate of" 含义相近,但:
"make an estimate of" 更强调“作出估算的动作”(更正式、书面);
"estimate" 动词用法更简洁(口语/书面均常用)。
例如:
动词:They estimated the cost at $10,000.(他们估计成本为1万美元。)
短语:They made an estimate of the cost at $10,000.(他们对成本作出了1万美元的估算。)
"make an estimate of" 是正式的估算表达,适用于需要明确“主动评估”动作的场景,核心是通过 "of" 引出估算对象,可灵活搭配修饰词或从句,是商务、工程、科研等领域的常用短语。
