let's to eat some food 的同义句qiu

what about eating some food?

这个句子明显存在语法错误。正确表达应该是Let's go to eat some food.同义句的表达法有多种：1）Why not go to eat some food?
2)How about going to eat some food ?

原问题错了。let后用动词原形，所以to是不需要的。
这句式是提建议
可以改为;Shall we eat some food？或 What(How)about eating some food?

错句，请修正后提交

It is import that we should eat some healthy food(用to do 句型改为同义句） It's important for us to eat some healthy food.

let's to eat some food 这个句子有错误，要么是let's go to eat some food 或者 let's eat some food。
同义句： Shall we go to eat some food？
