"let us go to swim this Sunday "suggested Tom 变间接引语

Tom suggested that they went to swim this Sunday.Tom suggested going to swim this Sunday.皆可!是they不是we!1.直接引语变为间接引语时,人称代词要根据转述人的立场作相应变动2.当引述的动词为过去时形式时,间...this Sunday 要不要改成that Sunday我看错了，这句话是祈使句，直接改成Tom suggested that they should go to swim this Sunday.为什么会用should?祈使句有什么用法?先纠正this需要改成that，我的疏忽因为像Let's是表达一中建议，一种提议那请问一下祈使句改间接引语的用法是什么直接引语若是以像Let's开头的这样的祈使句，变化时通常用suggest doing的句型或者用suggest+that从句，我这里用should是因为与原句的语气相符，Let‘s 是表达一种简易，改变时用should能体现这种建议的语气
