Notas para el profesor

Utiliza este test después de presentar los verbos modales de deducción o como prueba diagnóstica antes de un repaso. Se centra en los errores típicos del nivel B1: usar mustn't en lugar de can't para la deducción negativa, añadir to después de un modal, confundir maybe con may be y elegir must cuando las pruebas solo indican una posibilidad. Como actividad de seguimiento, pide a los alumnos que observen fotos o describan objetos misteriosos y hagan sus propias deducciones con must, might y can't.
