TOEFL iBT Listening “Listen to an Announcement”: cómo distinguir horarios, plazos, cambios y excepciones

Two adults listen to a briefing in a campus welcome area.

Cómo responder a las preguntas de “Listen to an Announcement” del TOEFL iBT en el formato introducido en 2026: distinguir la hora del evento de un plazo anterior, seguir qué cambia y qué se mantiene, y aplicar condiciones y excepciones al oyente correcto. Para candidatos de nivel B1 o superior.

En la tarea “Listen to an Announcement” del TOEFL iBT escuchas una sola vez un anuncio breve, por ejemplo sobre un evento del campus o un cambio de planes, y respondes preguntas de opción múltiple. Las preguntas son prácticas: para qué es el anuncio, cuándo y dónde ocurre algo, qué ha cambiado y qué debe hacer un oyente concreto. Las opciones incorrectas suelen reutilizar detalles reales del audio con un papel equivocado. Esta guía sigue el formato del TOEFL iBT introducido en 2026 y está pensada para candidatos con un nivel intermedio (B1) o superior.

¿Para quién es este artículo?

  • Candidatos que preparan el TOEFL iBT con el formato introducido en 2026 y captan el tema del anuncio, pero fallan las preguntas sobre horas, salas y requisitos.
  • Quienes oyen “Friday at four thirty” y “by Wednesday evening” casi seguidos y no saben cuál responde a “When must you book?”.
  • Estudiantes que van a un campus de habla inglesa, donde los anuncios reales cambian salas, retrasan horarios y fijan plazos.
  • Demasiado pronto: si todavía pierdes el hilo de un intercambio breve entre dos personas, empieza por elegir respuestas y seguir conversaciones (enlaces abajo).
  • Demasiado fácil: si puedes contar cada hora, cambio y condición después de una sola escucha, pasa a las charlas académicas (enlaces abajo).

Review the recording and transfer the skill

Good afternoon. The campus archive is offering an introductory workshop on using its digital collection this Friday at four thirty. The session will be held in the training room beside the archive entrance and will last ninety minutes. Places are limited to twenty participants, so please book through the archive website by Wednesday evening. You will receive a confirmation email when your place is reserved. Bring a laptop if you have one. A small number of loan laptops are available, but these must be requested by Tuesday so staff can prepare them. The workshop is designed for beginners; you do not need previous research experience. Please arrive ten minutes before the start so we can help everyone connect to the network. This is a practical workshop, not a general tour of the archive.

Your open task

  • Give an accurate spoken reminder to a beginner who needs a loan laptop.
  • Explain how the three different days relate to different actions.
  • Create your own short announcement for a learning event with a clear audience and one condition.

Separate What Changed from What Stayed the Same — worked model

Two adults listen to a briefing in a campus welcome area.

This is an update for the afternoon reading group. The session will start at the usual time, but it will move from the gallery to the seminar room because an installation team needs access to the gallery. The reading topic is unchanged. Please use the side corridor to reach the new room.

Listen for these relationships

  • Updated detail: seminar room replaces gallery.
  • Reason: an installation team needs the original space.
  • Retained details: the start time and topic.
  • Required response: follow the side corridor to the new room.
  • The update changes the location and the route, not the time or the content.

Listen for the main information

    The instruction is specifically for participants with arranged support for access.

Review the recording and transfer the skill

This message is for participants in Wednesday’s bookbinding workshop. The workshop will move from Studio B to Studio D because maintenance staff need to inspect the ceiling in Studio B. Studio D is in the same building, on the ground floor. To allow time for the materials to be moved, the workshop will begin at two thirty, half an hour later than originally planned. It will still finish at four. You do not need to bring any extra equipment; staff will transfer the tools and paper. Please bring your booking confirmation so we can check the attendance list quickly. If you have arranged support for access to the building, contact the organiser by Tuesday afternoon to confirm that the new room meets your needs. We will send a final reminder on Wednesday morning.

Your open task

  • Explain the revised plan, including the original and new start times.
  • Describe how the reason for the change affects the practical instructions.
  • Give your own update for a planned event, clearly stating one change and one unchanged detail.

Turn an Announcement into a Plan — worked model

Two adults listen to a briefing in a campus welcome area.

Volunteers for Saturday’s exhibition should complete the online safety briefing before their first shift. Those who have already completed it this month do not need to repeat it. Badges can be collected at reception from nine o’clock.

Listen for these relationships

  • A requirement can apply only to some listeners.
  • Already completed this month creates an exception.
  • Badge collection is a practical step, not proof that the briefing was completed.
  • Summarise instructions as actions in a sensible order.
  • The briefing requirement and the badge collection time are separate: arriving early does not replace completing the briefing.

Listen for the main information

  1. What must a new volunteer do before the first shift?

    Mostrar respuesta y explicación

    Watch the induction video and complete its check

    The opening requires both the video and the linked three-question check.

  2. Who does not need to repeat the induction?

    Mostrar respuesta y explicación

    Someone who completed it for last month’s exhibition

    The exception is specifically for people who completed this induction last month.

  3. What should a volunteer with a later shift do about the kit?

    Mostrar respuesta y explicación

    Collect it from the welcome desk when needed

    Later-shift kits are kept at the same desk, and early arrival is explicitly unnecessary.

Listen for relationships and next steps

  1. Why should volunteers collect their own kits?

    Mostrar respuesta y explicación

    Each kit is labelled for a named volunteer

    Named kits explain the instruction not to send a friend.

  2. What is the deadline for reporting that a volunteer cannot attend?

    Mostrar respuesta y explicación

    Five o’clock on Monday

    The cancellation instruction gives Monday at five as the deadline.

  3. How should a volunteer report that they cannot attend?

    Mostrar respuesta y explicación

    Email the coordinator

    Email reaches the coordinator; a public-post reply does not notify that person directly.

Review the recording and transfer the skill

Thank you to everyone volunteering at Tuesday’s community exhibition. Before your first shift, please watch the short induction video and complete the three-question check linked below it. If you completed this induction for our exhibition last month, you do not need to repeat it. On Tuesday, volunteer kits can be collected from the welcome desk between nine and nine thirty. If your shift begins later in the day, your kit will be kept at the same desk; there is no need to arrive during the morning collection period. Each kit is labelled for a named volunteer, so please do not send a friend to collect it. If you can no longer attend, email the coordinator by five o’clock on Monday so we can rearrange the rota. Replying to the public social-media post will not notify the coordinator directly.

Your open task

  • Explain the correct sequence for a new volunteer whose shift begins at noon.
  • Describe how the instructions differ for a returning volunteer.
  • Give a short announcement with a requirement, an exception and a clear contact route.

Qué te pide la tarea

Una sola persona habla a un grupo, por ejemplo a estudiantes o voluntarios. Ordena lo que oyes en cuatro apartados:

  • Propósito: por qué habla esa persona.
  • Evento: qué ocurre, cuándo y dónde.
  • Cambios: qué es nuevo, por qué ha cambiado y qué se mantiene.
  • Acciones: quién debe hacer qué, en qué plazo y quién queda exento.

¿Hora del evento o plazo?

Los anuncios suelen mencionar varias horas, y solo una es el evento. En el anuncio de un taller del archivo, el viernes a las cuatro y media es la sesión, el miércoles por la tarde es el plazo para reservar y el martes es un plazo anterior para pedir un portátil prestado. Une cada hora a su verbo y a su preposición:

  • at para la hora, on para el día o la fecha: la hora estándar de los ferrocarriles empezó “at noon on November 18, 1883”.
  • by para un plazo, el último momento para actuar: “please book through the archive website by Wednesday evening”.
  • until para algo que continúa hasta un punto: “The desk stays open until nine thirty.”
  • not … until para el primer momento en que algo ocurre: “Standard time did not become federal law in the United States until 1918.”

Prueba una: tres días, tres acciones

Lee dos frases de ese anuncio y responde:

  • “Places are limited to twenty participants, so please book through the archive website by Wednesday evening.”
  • “A small number of loan laptops are available, but these must be requested by Tuesday so staff can prepare them.”
“What should someone needing a loan laptop do?”

Qué ha cambiado y qué se mantiene

En una actualización, un taller de encuadernación pasa del Studio B al Studio D porque el personal de mantenimiento tiene que revisar el techo. Empieza a las dos y media (“half an hour later than originally planned”), pero la hora de fin no cambia: “It will still finish at four.” Una pregunta puede pedirte la hora de inicio original, que tienes que calcular tú: las dos. Señales que debes escuchar:

  • Cambio: move from … to …, instead of, rather than, no longer.
  • Motivo: because, so that, to allow time for.
  • Sin cambio: still, as usual, unchanged.
  • La pasiva pone el foco en lo que ha cambiado: “The workshop has been moved to Studio D.”
Aprende esta unidad a tu manera

Condiciones y excepciones: quién debe hacer qué

Muchas instrucciones solo valen para una parte de los oyentes. Los voluntarios deben ver un vídeo de introducción antes de su primer turno, pero el anuncio añade: “If you completed this induction for our exhibition last month, you do not need to repeat it.” Aplica cada norma a la persona sobre la que trata la pregunta:

  • Requisito: must, should, please, before your first shift.
  • Excepción: do not need to, there is no need to.
  • Condición: if, unless, as long as. Haberlo completado el mes pasado no es lo mismo que haber visitado la exposición.
  • Plazo y canal si no puedes asistir: “email the coordinator by five o’clock on Monday”. “Replying to the public social-media post will not notify the coordinator directly.”

Errores típicos

En español, «hasta el martes» puede marcar tanto lo que dura hasta ese día como el último día para hacer algo, y por eso es fácil decir “until Tuesday” donde el inglés pide “by Tuesday”: “Send it by Tuesday”, no “Send it until Tuesday”. Piensa en by como «a más tardar» y escríbelo junto a cada plazo en tus notas de práctica.

  • Dar la hora del evento cuando la pregunta pide cuándo debes reservar.
  • Elegir un lugar solo porque lo has oído: en “in Room C at six thirty, rather than the main lounge”, la sala principal queda descartada.
  • Aplicar un requisito a alguien a quien el anuncio exime.
  • Dar por hecho que todo ha cambiado: una sala nueva no significa una nueva hora de fin.

Rutina de práctica de 15 minutos

Usa anuncios de práctica con transcripción:

  • Escucha una vez y responde antes de volver a escuchar, como en el examen.
  • En la segunda escucha, rellena tres columnas: evento, plazos, cambios y excepciones.
  • En la transcripción, subraya by, until, still, instead, if y unless.
  • Cuéntaselo a un oyente concreto: “If you need a loan laptop, request it by Tuesday.”
  • Escribe un anuncio breve con un cambio, un detalle que se mantiene y una excepción.

Siguiente paso

Hazte estas preguntas con cada anuncio: “what exactly has changed, from when, and by when must I act?” Cuando puedas explicarle un anuncio a un amigo después de una sola escucha, pasa a las charlas académicas. Para practicar la expresión oral, responde a esta pregunta empezando con “An email works as long as…”: “What is the best way for a university to announce an important change: an email, an app notification or a notice in the building?”
