大家好，请问一下
1.
这个影片中
https://youtu.be/_DsMFD18BDQ?t=6
主持人说：“Or if something breaks in your car that is broken, you want to
make sure you repair that, too.”
不太懂中间的that is broken是什么意思，that是关系代名词，还是只是一般的代名词？
目前想到的理解是这样：if something breaks in your car, that is broken, you
want to make sure you repair that, too.
也就是that is broken当作插入句来解释，而that是一般的代名词。整句意思是“那就是
故障”。虽然整体来说不符合文法，但因为是口语，就不要太计较了。
