Hayley教口语，“拧瓶盖”用英语怎么说？

 unscrew 

/ʌn'skruː/

to take the lid or top off something by twisting it round

拧下…的盖子;把…顶部拧开

If you unscrew something such as a lid, or if it unscrews, you keep turning it until you can remove it.

如果你unscrew盖子之类的东西，或者如果它unscrew了，那么就是说你不停地转动它，直到你能把它拿下来。

I can't unscrew the top of this jar - it's really tight.

这个瓶盖我拧不下来——实在太紧了。
