From now on we have an MS meeting on every Wednesday morning, so every presentation ppt should be sent to 慧蘋 (Catherine) before Tuesday noon 12:00 for the English checking.

Catherine will check and highlight your incorrect English part with red color, but she will not correct the errors for you. You should correct the errors with blue color by yourself before you present.
All blue color should be maintained and be shown in the ppt when you present. If you cannot correct or you disagree the errors pointed by Catherine, please keep the red color there. 
I hope every student should follow this rule, otherwise, your presentation will be denied.
