调整到正常 meaning in English

tuning up

Of course , i quickly tried to look normal - - without looking like i was trying to look normal just because there was something going on that i was too much of an unsophisticated hick to witness without my mouth gaping open
当然，我很快就让自己调整到正常状态而且还努力不让别人看出我是在刻意让自己看起来好像什么都没发生过，只是出于这么一种心理在目睹这些事情发生的时候，我可不能像一个没见过世面的乡下人一样张大嘴巴。
