      Abenteuer im Ausland: perfect tense stem changes, perfect tense questions

      I can form the past participles of strong verbs with stem changes, and I can ask questions in the perfect tense about a past trip or experience.

      Lesson details

      Vocabulary and transcripts for this lessons

      Key learning points

      1. Strong verbs form past participles with 'ge-' and '-en' in the perfect tense.
      2. Some verbs have a vowel change in their past participle, such as 'ei' → 'ie', 'ie' → 'o', 'i' → 'u' or 'e' → 'o'.
      3. To form a closed question in the perfect tense, swap the position of 'haben' or 'sein' with the subject.
      4. For open questions in the perfect tense, place a question word before 'haben' or 'sein'; the subject follows.

      Keywords

      • Strong verb (perfect tense) - verb whose past participle adds ‘-en’ and often changes the stem vowel, e.g., 'geflogen'

      • Past participle - verb form that forms the perfect tense, together with the auxiliary verb

      • Closed question - a question which can be answered with yes/no, formed by inverting the subject and verb in a sentence

      • Open question - a question starting with a wh- word, followed by word order 2

      Common misconception

      Verbs with inseparable prefixes do not change when forming their past participle.

      Verbs with inseparable prefixes do not add 'ge-' when forming their past participle, but many do have vowel changes, e.g., 'vermeiden' becomes 'vermieden', 'empfehlen' becomes 'empfohlen'.

      The texts used for Task B2 could also be used to produce questions seeking futher information, as an alternative task or an extension to produce questions for the information given in the texts.
