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.

2 . Anvitha Vijay, who is only nine years old, has built two educational apps. One is Smartkins Animals, which helps many    1    (child) identify more than 100 animals and     2    other Rainbow Colors, which teaches kids colors.

With the help of YouTube videos, the young girl from Melbourne, Australia, learned to code (编程)at age 7 all by    3    (she). Soon, she was trying her hand at making apps. “When I first got my iPad, I     4     (attract)immediately by all the apps on it,” she told TFK. “It wasn’t long     5    I wanted to create my own.”

Anvitha’s skills won her scholarship to attend a big tech conference hosted by Apple in San Francisco, California. There, she got tips from the professionals and went to workshops     6    she learned about the latest software for app building. all that training led to an idea for a third app. This one,    7    (call) GoalsHi, inspires kids to practice good habits.

Anvitha’s goal is to continue crating technology that helps kids learn while    8    (have)fun. But what’s even more     9    (importance) to her is that the world sees the power of technology in kids’ hands. “The more training we get in tech at an early age,” she says, “the    10    (good)chance we will have of becoming innovation champions who will one day change the world.”
