给留学生说明需要更换床单时,可以使用以下表达:
1. 基础表达
直接请求:
"Please change the sheets."
礼貌表达:
"Could you please help us change the sheets?"
2. 场景化表达
术后护理(医疗场景):
"为了保持伤口清洁,现在需要更换床单,您看可以吗?"
酒店住宿问题(投诉场景):
"We've communicated with the staff but the sheets have not been changed. The front desk is unresponsive."
3. 补充说明
若需强调动作细节,可补充说明:
"Could you please roll up the current sheets, place the clean ones underneath, and smooth them out?"
建议根据具体场景选择表达方式,并注意使用礼貌用语以提升沟通效果。
