plan

Compared meaning: a plan of what to do (noun).

比较义项：计划（名词）。

• plan 本词

  A plan is a specific method or intention for reaching a goal; it can be simple and personal, and does not imply a formal sequence of events.

  plan 指为达成某个目标而制定的具体方法或打算，可以是简单的个人安排，并不意味着一系列正式的活动。

  We made a plan to visit the museum on Sunday.

  我们计划星期天去参观博物馆。

• program

  A program is an organized, often official series of planned activities (e.g. an educational or training program), rarely used for a single simple intention.

  program 指有组织、通常是正式的一系列既定活动（如教育或培训计划），很少用来表示单一简单的个人打算。

  The university offers an exchange program for international students.

  这所大学为国际学生提供一项交流计划。

Plan and program both mean an idea for future action. Plan is a specific method for reaching a goal; it can be small or informal. Program is a set of organized, official activities, common in schools or government. Program's computer sense is not compared.

plan 和 program 在“计划”这个意思上很接近，但 plan 更强调为达成某个目标而想出的具体方法或个人打算，可大可小、可正式可非正式；program 更强调一系列有组织、通常较为正式的既定活动或项目，常见于机构、学校、政府等场合。这里不比较 program 的“计算机程序”这一常见义项。

Compared meaning: a drawing showing how something is made (noun).

比较义项：图纸／图样，展示某物的布局或将如何被制作（名词）。

• plan 本词

  A plan is a drawing that shows the arrangement or layout of something, often seen from above (e.g. a building's rooms); it does not cover appearance or materials.

  plan（平面图）是显示某物布局或排列方式的图纸，通常从上方视角绘制（例如建筑物房间的布局）；它不涉及外观或材料。

  She studied the plan of the museum to find the nearest exit quickly.

  她研究了博物馆的平面图，以便快速找到最近的出口。

• design

  A design is a broader drawing showing how something will be made, including its shape, materials and appearance, not just how parts are arranged.

  design（设计图）是范围更广的图纸，展示某物将如何被制作，包括形状、材料和外观，而不仅仅是各部分的排列方式。

  The design of the new bridge covered its shape, materials, and layout.

  这座新桥的设计图涵盖了它的形状、材料和布局。

Plan and design both mean a drawing of something to be made. Plan shows the layout or arrangement, often seen from above. Design is broader: it also shows the shape, materials, and look. Plan's other meaning and design as a verb are not compared.

这两个词在这个义项上都指某种设计图纸，含义相近，但 plan 侧重于布局或排列（如平面图），而 design 范围更广，还包括外观和材料等制作方式。这里不比较 plan 的“计划，打算”义项，也不比较 design 作动词“设计”的用法。

Compared meaning: to plan or work out how to do something (verb).

比较义项：事先想好或设计做某事的方法（动词“计划”义）。

• project

  Project is formal, sometimes old-fashioned, and stresses devising a plan that reaches into the future, often on a large or official scale.

  project 语气正式，有时略显过时，强调构思一项面向未来才会实现的计划，常用于较宏大或官方的场合。

  Economists projected long-term policies to stabilize the currency over the next decade.

  经济学家构想了一套长期政策，计划在未来十年稳定货币。

• plan 本词

  Plan is the everyday, neutral word for deciding in detail how something will be done, with no special hint of skill, formality or difficulty.

  plan 是最普通、中性的用词，指详细决定该如何做某事，不带任何关于技巧、正式程度或困难的暗示。

  We planned our wedding down to the smallest detail.

  我们把婚礼的每一个细节都计划好了。

• design

  Design stresses working out a pattern and fitting parts together for a particular purpose, often producing something with a clear structure.

  design 强调构思出一种模式，把各部分组合起来以达成特定目的，结果往往具有清晰的结构。

  She designed a workout routine combining strength and cardio exercises.

  她设计了一套结合力量训练和有氧运动的健身计划。

• contrive

  Contrive suggests cleverness or ingenuity in reaching a goal despite obstacles or difficulty, and can hint at scheming.

  contrive 强调在克服障碍或困难的情况下，巧妙地想办法达成目标，有时还带有几分耍手段、耍心机的意味。

  The prisoners contrived a clever escape despite being watched around the clock.

  尽管一直被严密看守，囚犯们还是巧妙地策划了一次逃跑。

These words mean to think out a way to do something. Plan is neutral and everyday. Design stresses fitting parts into a pattern. Project is formal, about planning for the future. Contrive means finding a clever way despite difficulty. Noun uses are not compared here.

这几个词都表示事先想好要怎样做某件事，但语气和侧重不同：plan 最普通、中性；design 强调把各部分组织成有条理的方案；project 语气正式，强调计划指向未来；contrive 强调在困难中巧妙地想出办法，有时带有耍手段的意味。这里不比较 project 作名词表示“项目”、design 作名词表示“设计、图案”、以及 plan 作名词表示“计划”的用法。
