We’ve all turned to sad music to make us feel     1     (good)at some point in our lives, but why does doubling down on the sadness help drag us out of the mire(泥沼 )？

A new study sheds light on what’s going on inside our brains     2    we match our music to our feelings. It looks like sad music can be enjoyable -rather than     3    (simple) depressing- because it triggers positive memories that can help to lift our mood. Psychologist Adrian North from Curtin University in Australia says there     4     (be)two groups of possible    5     (explain)for why we enjoy listening to sad music like this: one from social psychology, and one from cognitive neuroscience(认知神经学).

In terms of social psychology, one way of     6    (think) about this is that we feel much better about     7     (we) if we focus on someone who’s doing even worse, a process known as downward social comparison. Everything’s going to be okay, because this person     8    (have) an even worse day than you are.

Another theory from social psychology is that people like to listen     9     music that mirrors the tone of their current life circumstances -the songs act as     10    sort of tuning fork(音叉) for our own situations and they resonate(共鸣) with us.
