ESL Verb Tense Practice Generator

English textbooks for native speakers barely mention tense as a system, but ESL learners get taught all twelve combinations explicitly, present, past, and future crossed with simple, continuous, perfect, and perfect continuous, because without that grid a learner has no map for why "I have lived here for ten years" and "I lived here for ten years" land so differently on a native ear. The two sentences share almost every word and still mean something different, one keeps the situation open and connected to now, the other closes it off as finished. That gap causes real, repeated errors, especially for learners whose first language marks past events with a single form the way Spanish often does, so both English sentences get flattened into one choice out of habit instead of two.

Tense focus is [TENSE_FOCUS:select:Present tenses (simple, continuous, perfect, perfect continuous),Past tenses (simple, continuous, perfect, perfect continuous),Future tenses (simple, continuous, perfect, perfect continuous),Present perfect vs simple past (contrast drill),Mixed practice across all twelve tenses]. CEFR level is [CEFR_LEVEL:select:A1 (beginner),A2 (elementary),B1 (intermediate),B2 (upper intermediate),C1 (advanced)]. I need [DRILL_COUNT:number:10-40] items.

If the learner's first language is known, name it in [L1_LANGUAGE?] so example sentences target the specific confusion that language tends to cause, otherwise build general-purpose items that cover the most common mistakes across learners broadly.

For present perfect versus simple past specifically, build paired sentences that are identical except for tense and a time signal, "I have visited Paris" against "I visited Paris last year," and require the learner to explain in one sentence what changes in meaning, not just which tense is grammatically correct, since picking the right label without understanding the meaning shift doesn't transfer to real speech.

For continuous forms, anchor each item to an interrupted or ongoing action a learner can picture, not an abstract example, since "was doing" only makes sense next to a concrete second event that interrupts it. For perfect continuous, keep the emphasis on duration up to a reference point rather than completion, since that's the detail separating it from the plain perfect.

Close by naming the two or three tenses most likely to get confused with each other given the chosen [TENSE_FOCUS], and build extra items specifically contrasting those pairs. If vocabulary gaps are slowing a sentence down as much as tense choice, build a companion vocabulary set at the same CEFR level before returning to this drill.
