The federal Justice Department has asked Mr Adams's federal charges be dropped, which is seen as a quid pro quo for his backing of Mr Trump's deportation policy.
And the reason that the French had the Q-U, Indicating a K sound is because of the influence of Latin, which used a Q before a U to make a W sound, like in quid pro quo.
法国人使用Q-U来表示K音的原因,是因为受到了拉丁语的影响。 拉丁语中,Q在U前用来发出W音,就像在“quid pro quo” (交换条件)这个词中那样。
