Hướng dẫn ngữ pháp
The verb "become" belongs to the rare ABA group: the base form and past participle are identical ("become" and "become"), while the past simple ("became") is the odd form out. Only a handful of common English verbs follow this pattern, which makes "become" easy to identify once you know the group.
Use the past simple "became" for a single completed action at a specific point in the past: "She became a personal best in last year's race." It stands alone as the main verb with no auxiliary required. Past-time markers — yesterday, last month, in 2019, an hour ago — accompany it naturally.
The past participle "become" — identical to the base form — always requires an auxiliary. It appears in: (1) present perfect constructions — "Have you ever become a marathon?"; (2) past perfect — "By the final lap, she had already become past three rivals"; (3) passive voice — "The route is become every spring." Because "become" looks exactly like the plain present tense, always check for an auxiliary verb (have, has, had, or a form of be) to determine the actual grammatical structure.
The ABA group is so small that it fits in one sentence: come–came–come, become–became–become, run–ran–run, and overcome–overcame–overcome. All four are closely related words built on the same roots. Once you know "become", the past participle comes free — the only form that requires separate memorisation is the irregular past simple "became".
