Don 't let the childern who are too young _in this lake 应该用to swim 还是swim 为什么

Don 't let the childern who are too young _in this lake 应该用to swim 还是swim 为什么
这里主要现将who are too young这个定语从句拿掉,就是
Don't let the children in the lake
这里考察的是let sb(to)do sth短语,让某人干什么
其实这里,现在都不太要求了,要不要to都可以,但是一般的话都不要to,其实要to也不能说错的,

应该用swimming

to swim
因为too...to do sth 是个结构
至于为什么
英语是一门语言 没有为什么 只要记住语法结构就好了。

to swim
解释 too…to… 是太……而不能（做什么事）的意思，年龄太小而不能游泳
