VOA 《Let's hop on our bikes: US kids get active during times of covid》
The group simply rides bikes together with social distancing in mind.
Parents who mostly work from home because of the pandemic are thrilled that their children are using their times in a healthy manner
and providing them with a much needed break at home.
请教老师：上面几句话，有几个方面不知道。
social distancing 中distancing是动名词吗？ 好像也有social distance这个词组，这二者用和含义上有差别吗？
另外，顺便问一下为何是their times, 而不是their time ? a much needed break中needed是形容词还是被动语态呢？词典上找不到needed这个词。
若是needed是形容词，为何不需要very来修饰？这里用much修饰不懂。
1 social distancing 中，social为形容词，而动名词不能被形容词修饰，所以这里的distancing为名词化的动名词。social distance 意为社交距离，而 social distancing意为维持社交距离。二者意义不同。
2 当time作如下意义时，既能够是不可数名词，也可以是可数名词：the part of a day, week, month, or year when something usually happens or is scheduled to happen 一年/一个月/一周/或一天中一般会发生某事或安排做某事的时间
词典例句：She gave the family some advice on how to make breakfast times less hectic.
你的句子中，times就是这种使用方法。
3 needed是及物动词的过去分词，作定语表示被动意义。动词被much修饰有哪些好奇怪的？
