特定任务用英文怎么说写

"特定任务" (specific task) 可以用英文表示为 "specific task"。这个词来源于拉丁文 "species" 和 "facere"，"species" 意为 "种类"，"facere" 意为 "做"，因此 "specific" 可以表示 "特殊的" 或 "具体的"。

例句：

"She was assigned a specific task to complete before the end of the day." (她被分配了一项在当天结束前完成的特定任务。)
"The specific task he was given was to organize the office supppes." (他被分配的特定任务是整理办公用品。)
"He is responsible for completing the specific task of preparing the presentation." (他负责完成准备演讲的特定任务。)
