Go to TED Talks and watch a longer talk (at least 5 min.) that you are interested in. Choose a video/topic that you can actually TALK about, i.e. do NOT take a video that is mainly about music, pictures, paintings or art in general. If you have problems understanding the speaker, activate English (!) subtitles and/or the „interactive transcript“. Prepare/practise a short talk in which you tell your fellow students about „your“ talk. You may use notes, but keywords only, no complete sentences.
