This listening comprehension activity I found on BBC Skillswise aims to train your listening skills in getting specific information from telephone messages.
Firstly, you have to go to the activity page. Follow the instructions listed there.
Now, pick up the question sheet and begin with the first activity.
After finishing the first part of this activity, you can continue with filling in the gaps on the other worksheet.
You’ll find the answers here and here. Enjoy listening to the different accents on the answerphone, and tell me what you think about it.
