Choose the correct form of the verb 'visit' in the past simple.
Elige una opción para comprobar tu respuesta.
Respuesta correcta: A)Last Saturday our class visited the market in Otavalo.
💡 Explicación
A regular verb in the past simple takes -ed after the base form: work becomes worked, play becomes played, visit becomes visited. Only verbs ending in -e drop the final letter before -ed, and verbs ending in a consonant plus y change the -y for -ied: study becomes studied.

Respuesta correcta: A)Last Saturday our class visited the market in Otavalo.
A)Last Saturday our class visited the market in Otavalo.Correct! The regular past of 'visit' takes -ed: visit becomes visited, with no change to the pronunciation of the -ed.
B)Last Saturday our class visit the market in Otavalo.'Visit' is the base form and belongs to the present, so it cannot describe an action that happened last Saturday.
C)Last Saturday our class visiteds the market in Otavalo.'Visiteds' adds -ed to a base form that already ends in a consonant, which is not how English forms the past tense.
D)Last Saturday our class visiting the market in Otavalo.'Visiting' is an -ing form of the present continuous or the gerund, not the finite past form of the verb.
💡 Explicación
A regular verb in the past simple takes -ed after the base form: work becomes worked, play becomes played, visit becomes visited. Only verbs ending in -e drop the final letter before -ed, and verbs ending in a consonant plus y change the -y for -ied: study becomes studied.

Choose the correct past simple form of the irregular verb 'grow'.
Elige una opción para comprobar tu respuesta.
Respuesta correcta: D)My grandfather grew tomatoes in the garden behind the house.
💡 Explicación
Irregular verbs change their internal vowel instead of adding -ed: grow grew, drink drank, speak spoke, take took. There is no rule that produces these forms, so they belong to the list of verbs every student memorises. The context word 'was' is the clue that the sentence needs a past form.

Respuesta correcta: D)My grandfather grew tomatoes in the garden behind the house.
A)My grandfather grewed tomatoes in the garden behind the house.Irregular verbs have a fixed past form, so 'grew' is required and 'grewed' does not exist in English.
B)My grandfather growed tomatoes in the garden behind the house.'Growed' applies the regular -ed pattern to an irregular verb, and 'grow' does not take that form in English.
C)My grandfather grows tomatoes in the garden behind the house.'Grows' is the present simple form and describes a repeated action, not a childhood memory.
D)My grandfather grew tomatoes in the garden behind the house.Correct! 'Grow' is an irregular verb whose past simple is 'grew', a different word that has to be learned by heart.

We did not go to the beach last Sunday because it rained all day in Manta.
Choose the sentence that correctly uses the negative past simple with an irregular verb.
Elige una opción para comprobar tu respuesta.
Respuesta correcta: B)We did not go to the beach last Sunday.
💡 Explicación
The past simple negative uses 'did not' followed by the base form of the verb. This holds for regular and irregular verbs alike: he did not work, he did not go, she did not write. Writing 'did not went' mixes two tenses in one verb phrase.
Ver respuesta
Respuesta correcta: B)We did not go to the beach last Sunday.
A)We did not went to the beach last Sunday.'Went' is the past form, but a past form cannot follow 'did not'; the auxiliary already marks the tense.
B)We did not go to the beach last Sunday.Correct! Once the auxiliary 'did' carries the past tense, the main verb returns to its base form: 'did not go', never 'did not went'.
C)We did not gone to the beach last Sunday.'Gone' is the past participle used with 'have' or 'been', not the form that follows 'did not'.
D)We not did went to the beach last Sunday.English places the auxiliary 'did' before the pronoun, and the negative 'not' always comes after the auxiliary.
💡 Explicación
The past simple negative uses 'did not' followed by the base form of the verb. This holds for regular and irregular verbs alike: he did not work, he did not go, she did not write. Writing 'did not went' mixes two tenses in one verb phrase.

Respuesta correcta: C)No, I didn't finish it.
💡 Explicación
Short answers in the past simple have the same shape as in the present: pronoun plus contracted auxiliary. 'Did you finish?' is answered with 'No, I didn't', and the verb does not reappear in its past form. The same rule applies to 'Yes, he did' and 'Yes, she wrote' when the question is reopened.

Respuesta correcta: C)No, I didn't finish it.
A)No, I don't finished it.'Don't' marks the present, so it cannot answer a question that was built with 'did'.
B)No, I didn't finished it.'Finished' is the past form, and adding it after 'didn't' marks the tense twice in the same verb phrase.
C)No, I didn't finish it.Correct! 'Didn't' already carries the past tense, so the verb stays in its base form: 'didn't finish', not 'didn't finished'.
D)No, I not finished it.A negative short answer needs the contracted auxiliary, which is 'didn't'; 'not' alone cannot form one.
💡 Explicación
Short answers in the past simple have the same shape as in the present: pronoun plus contracted auxiliary. 'Did you finish?' is answered with 'No, I didn't', and the verb does not reappear in its past form. The same rule applies to 'Yes, he did' and 'Yes, she wrote' when the question is reopened.

Respuesta correcta: A)The students painted the walls of the community centre last year.
A)The students painted the walls of the community centre last year.Correct! 'Paint' is a regular verb whose past simple is 'painted', formed by adding -ed to the base form.
B)The students paints the walls of the community centre last year.'Paints' is the third person singular of the present simple and cannot describe a completed action of last year.
C)The students painting the walls of the community centre last year.'Painting' is an -ing form; the finite past simple needs the form 'painted' after the subject.
D)The students have paint the walls of the community centre last year.'Have paint' is not a valid combination: after 'have' a verb needs its past participle, which here would be 'painted'.

Choose the correct past simple form of the verb 'erupt'.
Elige una opción para comprobar tu respuesta.
Respuesta correcta: C)The volcano erupted at night.
💡 Explicación
Adding -ed produces three pronunciations: it sounds like -t after an unvoiced consonant such as p, k or f, like -d after a voiced one such as b, g or l, and like -id after t or d. Spelling stays constant even when pronunciation changes, so 'erupted' is written the same way it is spoken.
Ver respuesta
Respuesta correcta: C)The volcano erupted at night.
A)The volcano erupt at night.'Erupt' is the base form; a completed action described as 'at night' needs the past tense.
B)The volcano eruptes at night.'Eruptes' is a third person present form and does not exist as a past form in English.
C)The volcano erupted at night.Correct! 'Erupted' is the regular past form of 'erupt', built with -ed and pronounced as a -t sound in the middle.
D)The volcano erupteted at night.'Erupteted' repeats the -et ending, which is not a formation used in the past simple of English verbs.
💡 Explicación
Adding -ed produces three pronunciations: it sounds like -t after an unvoiced consonant such as p, k or f, like -d after a voiced one such as b, g or l, and like -id after t or d. Spelling stays constant even when pronunciation changes, so 'erupted' is written the same way it is spoken.

Spelling in the past simple has two patterns. Regular verbs mostly add -ed, and those ending in a single vowel plus a consonant double that consonant: stop becomes stopped, travel becomes travelled. Irregular verbs keep their own past form, and swim, begin, run and sing belong to that group.
Ver respuesta
Respuesta correcta: D)My family travelled to the coast and we swam every morning in the pool.
A)My family travel to the coast and we swam every morning in the pool.'Travel' is the base form, so it describes the present rather than a trip that took place in 2024.
B)My family traveled to the coast and we swimmed every morning in the pool.'Swimmed' doubles the consonant of the present form, but 'swim' is irregular and its past is 'swam'.
C)My family travelled to the coast and we swimed every morning in the pool.'Swimed' applies the -ed rule to an irregular verb, and 'swim' does not take that formation in English.
D)My family travelled to the coast and we swam every morning in the pool.Correct! Both verbs are correct: 'travelled' doubles the final consonant after a stressed short vowel, and 'swam' is the irregular past of 'swim'.

Some verbs end in a consonant plus -ed and take no -ed at all, such as call called, like liked, want wanted and need needed. Their past form looks identical to the present simple, which makes them easier to learn but easy to misread when a sentence mixes tenses.
