"Became"作为动词become的过去式，用于描述在过去某一时间点发生的动作或状态的变化。它的结构简单，由be动词的过去式加-ed构成，如"am, is, are"的过去式分别是"was, were"，所以become变为了"was"或"were"加上"become"的过去分词"become"，即"became"。

二、时态和语态

"Became"用于一般过去时，表示动作或状态在过去某一时刻发生并完成。例如：

• Subject + became: He became a doctor after years of hard work.
• Subject + was/were + become: The weather was becoming colder as the day went on.

三、否定和疑问形式

否定形式是通过在"did"后面加not，然后接"become"的原形，如"didnt become"。疑问形式则在句首加助动词"did"，如"Did he become a teacher?"

四、非限定动词

当"became"与介词连用，如"because of"或"as a result of"时，它通常转变为形容词，表示原因或结果。例如：

• His success became a source of inspiration.
• The decision becoming clearer after careful consideration.

五、实例分析

通过以下例句，进一步理解"became"在实际语境中的应用：

• She became aware of her passion for painting when she was young.
