You are very selfish.It’s high time you realized that you are not the most important person in the world,” Edgar said to

It's high time that sb did sth
某人是时候做某事啦
译为：“你太自私了,是时候让你明白你不是世界上最重要的人的道理啦!”埃德加怒气冲冲地向他老板讲道.
that 引导的宾语从句确实是realized的宾语~
这里套用就是为了加强语气~那么high time 的 that 的呢?it's high time that 中It 是形式主语，that 引导的从句是真正的主语，你说呢？对啊 那应该是It's high time thatyou realized that哈，我把自己给带沟儿里啦~it's high/about time 本来就是口语中的非正式表达，（此句援引于牛津高阶词典）也就没有that参考下词典中的例句吧~It's about time you cleaned your room! 你是时候打扫打扫房间啦~
