Tips

While Holds the Background; When Drops the Event

  1. Background bar → was/were + -ing. Bounded point event → simple past. Connector choice follows the relationship.
  2. While/when apoyan la lectura; no seleccionan automáticamente la forma.
  3. El orden de las cláusulas puede cambiar sin alterar la relación temporal.
