gearbox的音標(biāo)是[?ɡearb?ks]，基本翻譯是“變速器”。

速記技巧可以參考：在英文單詞中，gear常用來(lái)指機(jī)械設(shè)備等的“部件”、“零件”，box指的是箱子，結(jié)合起來(lái)指裝載、傳輸、轉(zhuǎn)換設(shè)備的部件，變速器。在記憶時(shí)可以結(jié)合實(shí)物模型或圖片進(jìn)行記憶，加強(qiáng)記憶效果。

Gearbox這個(gè)詞的詞源可以追溯到古英語(yǔ)中的“geare”這個(gè)詞，意為“齒輪”。它最初是指齒輪的組合，后來(lái)逐漸演變?yōu)橹刚麄€(gè)變速箱。

Gearbox的變化形式包括復(fù)數(shù)形式“gearsboxes”，過(guò)去式和過(guò)去分詞形式“geared”和“geared-up”，現(xiàn)在分詞形式“gearing”。

英文小作文：

Gearbox is an essential part of any vehicle, which transmits power from the engine to the wheels. It ensures smooth and efficient movement of the vehicle. However, like any other mechanical component, it requires regular maintenance and replacement when it is damaged beyond repair.

Gearbox replacement is a complex task and needs expertise and experience to carry out properly. It involves dismantling the vehicle, removing the damaged parts, and installing new ones. This process can be time-consuming and costly, but it is necessary to ensure safe and efficient operation of the vehicle.

On the other hand, regular maintenance of the gearbox can help detect any issues early and prevent them from getting worse. This includes inspecting the condition of the components, lubricating them regularly, and ensuring they are in good working condition. Regular maintenance also helps extend the life of the gearbox, reducing the need for replacement and saving money in the long run.
