问题描述:

The robot didn't know when to cook breakfast.The robot didn't know when____ ____ ____breakfast.
改为同义句

it should cook
when to cook = when it should cook 什么时候应该做饭填it would cook 对吗?(这是老师说的答案,would是will的过去式)也说得过去should意思是应该,应当,would 意思是将要所以 should更适合些,这个机器人不知道何地去做早饭。~~~~~~~~~~~~~~~~祝你进步,如对你有帮助,请及时采纳~~~~~~~~~~~~~~~~
