Common mistakes
You should lubrication the engine regularly.You should lubricate the engine regularly.
lubrication 是名词，lubricate 才是动词；情态动词 should 后接动词原形，因此要用 lubricate。

lubricate 的宾语是被润滑的对象，而润滑剂要用介词 with 引出；把 oil 当作宾语、用 to 引出机器属于搭配错误。

Pronunciation & Spelling
lubricate 读作 /ˈluːbrɪkeɪt/，重音在第一音节，押韵部分为 /uːbrɪkeɪt/。列表中没有一个词与之完全押韵。fabricate（/ˈfæbrɪkeɪt/）与它拥有相同的 /brɪkeɪt/ 结尾，但重读元音不同（/æ/ 对 /uː/），所以不押韵；duplicate（/ˈduːplɪkeɪt/）仅重读元音同为 /uː/，后续辅音不完全相同；communicate 的重音在第二音节；allocate、indicate 的重读元音分别为 /æ/、/ɪ/；intricate 作形容词时结尾读 /ət/，不是 /eɪt/。注意这些词只是拼写相似，发音需逐个记忆。
