用法要点

句型搭配

dodecahedron 通常作为名词使用,在句子中作主语或宾语,描述几何形状或物体。

• a regular dodecahedron
• the shape of a dodecahedron
• construct a dodecahedron

介词用法

常用介词如 'of' 表示所属关系,'in' 表示在某种形式中,'with' 表示具有某种特征。

• a model of a dodecahedron
• in the form of a dodecahedron
• a solid with dodecahedral faces

语域说明

dodecahedron 属于正式或学术语域,多用于数学、物理、工程等专业领域,日常对话中较少使用。

• in mathematical proofs
• in architectural design
• in scientific discussions

基础例句

I saw a dodecahedron in the math class today; it had twelve faces.

今天在数学课上我看到了一个十二面体,它有十二个面。

Can you help me build a dodecahedron out of paper for the project?

你能帮我用纸做一个十二面体来完成这个项目吗?

The toy is shaped like a dodecahedron, which makes it interesting to play with.

这个玩具形状像十二面体,玩起来很有趣。

高级例句

In crystallography, a dodecahedron is often used to describe certain mineral structures.

在晶体学中,十二面体常用来描述某些矿物结构。

The engineer designed a dodecahedron-shaped module for the space station to optimize volume.

工程师为空间站设计了一个十二面体形状的模块,以优化空间体积。

Advanced geometry courses cover the properties of a dodecahedron, including its angles and symmetry.

高级几何课程涵盖十二面体的性质,包括其角度和对称性。

常见错误

❌ 错误:I have a dodecahedron of twelve sides.
✓ 正确:I have a dodecahedron with twelve faces.

错误在于使用了 'sides' 而不是 'faces'。在几何中,dodecahedron 有 'faces'(面),'sides' 通常用于二维图形如多边形。应改为 'with twelve faces' 以准确描述。

❌ 错误:This is a dodecahedron shape object.
✓ 正确:This is an object shaped like a dodecahedron.

错误在于词序和表达不自然。'dodecahedron shape object' 是中式英语,应使用 'shaped like a dodecahedron' 来使句子更流畅和地道。

近义词辨析

polyhedron

polyhedron 是更通用的术语,指任何由平面组成的立体图形,而 dodecahedron 特指有十二个面的多面体。

A cube is a polyhedron, but only a dodecahedron has exactly twelve faces.

icosahedron

icosahedron 指有二十个面的立体图形,与 dodecahedron 在面数上不同,但都属于多面体家族,常一起讨论几何性质。

While a dodecahedron has 12 faces, an icosahedron has 20, making them distinct in symmetry studies.
