6. Teachers expect all their students _____ progress day by day.
A. to make B. make C. to take D. take

D. how long it takes you to walk to school
【解析】考查宾语从句。句意：——莉莉，你能告诉我从你家到学校要花多长时间么?——大约十分钟。how far多远(距离);how long多长时间。tell me后是宾语从句，用陈述句的语序(主语+谓语动词)，A和C语序错误。根据"About ten minutes"表达一段时间"大约十分钟"，可知宾语从句用how long。故选D。
