geodesic的音標為[?d?i???d?s?k] ，基本翻譯為“測地線；測地線法”，速記技巧為：測地線是兩點之間最短距離的線條。

Geodesic這個詞來源于希臘語詞根“geo”，意為“地球”，以及“desikó”或“dēskein”，意為“穿過”。因此，geodesic指的是地球上的“穿過”或“經過”某物。

變化形式：在英語中，geodesic通常使用其復數形式，即geodesics。

英文小作文：

Geodesics on a Sphere

When we think of geometry, we often imagine lines and shapes on a flat surface, but what about on a curved surface like the Earth? One example of geometry on a curved surface is geodesics, which are paths that follow the shortest distances between points on the surface of a sphere, like on a globe.

When we look at a globe, we can see that geodesics are curved lines that connect different points on the surface. They form a shape that looks like a network on the surface of the sphere. Geodesics are important in many fields, including geography, navigation, and even in physics when studying the motion of objects on curved spaces like black holes.

To understand geodesics better, we can use tools like trigonometry and calculus to study them more deeply. These tools help us understand how angles change along geodesics and how objects move along them. Understanding geodesics can help us better understand our world and how things work in it.

In conclusion, geodesics are paths that follow the shortest distances on the surface of a sphere, like on a globe. They are important in many fields and help us understand our world better.
