gearing 的音標是[?ɡ??r??]，基本翻譯是“齒輪；傳動裝置；配重；傳動比”。速記技巧是將其分解為單詞的組成部分并進行聯想記憶。例如，可以將“gearing”拆分為“gear”（齒輪）和“ing”（動詞后綴），從而聯想到齒輪等傳動裝置相關的概念。此外，還可以通過對比記憶法來記住含有相同字母組合的單詞，如“ring”（戒指）和“ringing”（鈴聲），從而更好地記住“gearing”的拼寫和含義。

Gearing這個詞的英文詞源可以追溯到古英語中的“geare”這個詞，意為“齒輪”或“傳動裝置”。它的變化形式包括復數形式“geare”和過去式“geared”等。

英文小作文：

Gearing up for the Future

Life is like driving a car, with different gears to help us accelerate, decelerate, and change directions as we navigate through life"s challenges and opportunities. Whether it"s learning a new skill, achieving a goal, or simply preparing for the future, we need to constantly gear up and shift into the right gears to move forward.

Gearing up also means being ready to adapt to changes and seize opportunities as they arise. It"s not about being stuck in one gear, but about constantly shifting and optimizing our resources to reach our full potential. Whether it"s a personal or professional setting, we need to be constantly aware of our gears and how they affect our progress and success.

In conclusion, gearing up is not just about physical fitness, but also about mental preparedness and adaptability. It"s about being ready for whatever life throws at us, and seizing the opportunities that come our way. So, stay sharp, stay ready, and always keep your gears in top shape!
