什么是 “design sb to do sth”？
在英语中，“design sb to do sth” 并不是一个标准或常见的搭配。 实际上，“design” 通常不直接接人作宾语再加不定式（to do）。 正确的用法通常是：
design something to do something（设计某物以实现某种功能）be designed to do something（被设计用于做某事）
如果你想表达“安排/指派某人去做某事”，应使用其他动词，如 assign、task 或 appoint。
正确用法示例
The car was designed to save fuel.
They designed the app to work offline.
This tool is designed to simplify complex tasks.
常见误解与纠正
错误： ✘ They designed him to complete the project.
正确： ✓ They assigned him to complete the project.
正确： ✓ He was tasked with completing the project.
“Design” 强调的是“设计物品或系统”，而非“指派人”。混淆常源于中文直译。
