Well done. You started by listening to the level 1 article 'Midi au parc' which is a challenge for all learners. Now you know most or all of the vocabulary, have looked at a translation and have a better understanding of the French you will be able to understand more of the recording. You may want to repeat the process until you are very comfortable with this recording.
We recommend that you re-visit recordings you've completed from time to time to help you retain your French. You may want to save the recordings to your mp3 player or iPod and play them in the case.
Query any points of grammar you don't understand with your French teacher.
