it's time to bed对么？

Question

it's time to going bed
it's time to go bed
it's time for go to bed
it's time for going bed
哪个对，为什么对

Answer 1

如果用it's time to的话就是
It's time to go to bed.
该睡觉了。
It's time for sth.意为：该是去xxxx的时候了
It's time for bed = It's time to go to bed.

Answer 2

都不对，一楼也不对。应该是：
It's time to go to bed.
句型：It's time to do sth.
go to bed，go是不及物动词，要有介词to连接宾语bed。

Answer 3

it's time to go bed 对的。。

有个词组：it is time （for sb） to do

sth 、、 所以it's time to going bed
是错的、、

it is time for sth 、、 所以， it's time

for going bed 和it's time for go to bed是错的。。

Answer 4

没有一个对的

it is time to go to bed

it is time to do something是固定用法，语言这东西没有什么为什么。
就像有一次老外问我，中文中，为什么非要管“方便面”叫方便面？ 不叫速食面，因为英文是instant noodle，为什么管杂货店也叫便利店，不叫方便店？

我哑口无言

Answer 5

it's time to go bed才对
因为to后只能用动词原形，除了look forward to等等
it's time for后加名词
他们都表示什么时间到了
