Слова в Past Simple . drive/break/spend/get/not can/be/not know/find/stay/see/buy/want/not have/start/leave

Как носитель на сайте я бы ответил так:

• drive → drove

• break → broke

• spend → spent

• get → got

• not can → could not (couldn’t)

• be → was / were (I/he/she/it — was; you/we/they — were)

• not know → did not know (didn’t know)

• find → found

• stay → stayed

• see → saw

• buy → bought

• want → wanted

• not have → did not have (didn’t have)

• start → started

• leave → left

Памятка: в Past Simple отрицание образуется через did not + инфинитив (кроме be и модальных — у них свои формы was/were, could not). Правильные глаголы получают -ed (stay → stayed, want → wanted, start → started), неправильные меняют корень (drive → drove, buy → bought и т. п.).
