问题描述：
That's no reason to stop it.为什么不是There's no reason ...
如题,并请帮忙分析That's no reason to stop it.这种用法,
问题解答：
我来补答
Teenagers like to gossip, and they often see something that isn't real. Perhaps your classmates cannot understand your friendship with this boy. That's no reason to stop it.
答：这句话摘自《 Unit_1_Friendship》的小课文.
That指代前面的这种情况,即同学们的不理解,不是你终止这种友谊的理由.
而there is no reason to stop it. 表示“没有理由终止这件事情”.意思不一样.
再问： 那不应该是： That's not the reason to stop it.吗？ 即，我不是很理解that is no reason这种结构和用法，请帮忙分析下，谢谢！
再答： no=not a +可数名词单数 no= not any +可数名词复数/不可数名词
