I see not too many wanted to tackle this one...lol So in the context of the song, "get low" refers to a form of dancing in which the person is dancing while getting as low to the ground as possible. If you watch the video to the song, it will make a little more sense.

Basically, it means that even the worst situation has some good that can come from it. The usual phrase you may hear is "in every cloud lies a silver lining." I'm not really sure why this particular analogy was chosen, but that is the meaning.

He studies hard in order to be accepted into a good University. He wants to attend a good University, so he studies hard.

In this case, "Romance" has a different meaning. It could mean (mystery) for example. So, It's from (The Mystery of the Three Kingdoms)

1) Yes 2) Honestly, I think there is no specific phrase for this one. So yes, I would say your statement is acceptable. Could we (show), could we (move to), Could we (see).... I think these are just a few of many ways to get the idea across. 3) A little odd.... Again, no specific phrase in my opinion... but I would probably simply say, "uh oh, seems like we have a problem." "seems like the projector went down." So many things could be said.

Lol......that's a tough one, and something natives rarely if ever think about... I'll be honest, i'm struggling to come up with a logical answer. If I had to give a reply, I would say it perhaps has to do with specificity. "The" pressure is for a specific pressure, not just any pressure... For example, you as a person my have no problem stepping up to the plate and hitting a home run for the baseball team. In this case, it's still pressure, but that pressure doesn't bother you. However, if I ask you to speak in front of 150 people, perhaps that is not pressure you do well with....and when "the" pressure is on, you fall short..... Again, specific pressure to a specific situation. Hopefully that makes some sense.....lol

I think if you add "the" you'll be good to go. Does (the) design have flexibility?
