To give MLCers a good chance to upgrade their presentation skills, MLC HA organized a new form of presentation activity, PPT Karaoke on September 27, 2018. Participants used a PowerPoint slide that they had never seen to give a five-minute speech. They had to organize their language, logical thinking and make instant response. The activity provided MLCers a good platform to try a brand new form of presentation that they never tried in normal classes before.
