''Let's go home.''said Tom.直接引语改为间接引语

问题描述:

''Let's go home.''said Tom.直接引语改为间接引语

Tom said ,let them go home .

Tom said that they should go home

Tom asked them to go home.
祈使句要用ask tell order来

Tom said that they would go home.

我觉得还是Tom said let's go home.汤姆说咱们回家吧.
如果原句是"Let us go home ."said Tom 我觉得应该改成Tom said let them go home.汤姆说让他们回家吧.
期待有更准确的回答.
