3. Listening: The Launch Abort System

Listen to recording 07 on the CD that comes with your book (Bonamy, D. (2011). Technical English Level 3 Coursebook. Pearson Longman). As you listen, do this gap-fill task. Alternatively, you can read the transcript on p. 119. The completed gaps will then serve as an overview of two English verb tenses: The Present Perfect tense and the Past Simple tense.
