Respuesta: <br>1. My father traveled to Santiago last Summer.<br>2. I did not study for the English test.<br>3. Did you go to the mall last Saturday?<br>4. Peter did not buy the car he wanted.<br>5. Did you study for the test?<br>6. What did your mom cook yesterday?<br>7. When did Tom drink the milk?<br>8. Where did you go yesterday?<br>9. Did she win the tennis match?<br>10. What did they see in London?<br><br>Explicación: En este caso, se usan verbos en pasado y negaciones en pasado en inglés. Los verbos regulares en el pasado se forman añadiendo "-ed" al infinitivo (travel-traveled), pero muchos de los verbos que se presentan en este ejercicio son irregulares y su forma en pasado hay que aprenderla de memoria (go-went, see-saw, drink-drank). Para las negaciones, se utiliza "did not" seguido del verbo en infinitivo (did not study, did not buy). Para hacer preguntas en pasado, se utiliza "did" al comienzo de la oración, seguido del sujeto y del verbo en infinitivo (Did you go, Did she win).
