Eng0--ask tense

“The kettle boiled.”
「那個水壺煮沸了。」???
呢句好似唔多o岩。
首先，boiled可以係一個verb，個tense (時態)係past tense(過去式)；亦可以係個adjective，代表煮熟的 / 煮沸的。(此句應採用第一個解釋)
要留意o既係，boil的受語應該係以水煮的食物或水，你唔可以話個kettle被煮熟的，所以建議你把該句改做〝The water (in the kettle) is boiled.”= 「(水壺中的)水被煮沸了。」，咁boiled在呢處的tense都係past tense (過去式)但係變左做被動語態 (passive voice)。

The kettle ( 可當作 = The water in the kettle )
例如 : I' ll boil the kettle and make some tea .

The kettle is / was boiled . ---- > ( passive form ) ( sentence )
= The water in the kettle is / was boiled . ---- > ( passive form ) ( sentence )
= The kettle which is / was boiled . ---- > ( relative clause ) ( phrase )
= The kettle boiled . ---- > ( participle ) ( phrase )

The kettle boiled ( = noun phrase )
boiled ( = past participle )
boiled ( = adjective )

The kettle boiled 是一個片語 , 冇 main verb , 冇 tense 可言 ,

係verb
時態係past tense
