When did you ...?

你什么时候……？

A lesson on asking and answering past-tense questions with time phrases (at + times, on + days/dates, in + months/years). Students practice reading clocks, writing past-tense answers about appointments, and sorting time words into the correct preposition columns. Written exercises include completing sentences in the past tense and answering questions about past events with appropriate time phrases. Workbook practice covers prepositions of time (at/on/in) and personal questions about past experiences. Grammar exercises ask and answer questions using cues and fill in blanks with correct verb forms (present and past tense) in a narrative about the Scott family and their son Sam.
