第一节(满分15分)One possible version:Dear Ryan,I'm Li Hua,from one of the project groups.I'm writing to tell you a problem in our group.Our team's project is progressing slowly due to some members'low participation.They seldom join in discussions orfinish their work on time,greatly holding back our progress.To fix this,I suggest assigning specifie tasks with clear deadlines to everyone.Besides,regular progress checks canurge all members to take their work seriously.I also suggest asking everyone to report what they have done.In this way,each member will take more responsibility and our group can work better.I would appreciate it if you could consider my suggestions.Yours,Li Hua
