可能是我们的沟通产生了一些误解；
我们一直以为出差的时间是3-17日开始，但是上周五通过电话才得知你们把开始日定在了4-2
另外，关于这次出差，蔡先生要在意大利待2周，而我则要待四周；
是否能确认培训开始的时间以便我们可以预定机票
參考答案:Perhaps there are some misunderstanding in our communications. We assumed that the date for travel on business begins on 17th, March, however, we learned from the phone on last Friday that you fixed the begining date on 2rd,April. In addtion, Mr. Cai will stay in Italy for two weeks, while I will stay for 4 weeks.
Would you please confirm the beginning date for training so that we can make a reservation for the air ticket.
