请帮我分析一下下面句子里would have to do和would do 怎么解释啊？搞不懂~

Question

When this happened, my friend would have to go in the hole. He would go into debt and owe people money.

Answer 1

其实这里would have to do 和 would do 是一样的句型。都是 would 后加动词原型，即would do sth.
只不过would have to do是把 would do sth（表“将来“） 与 have to do sth（不得不做某事）结合起来了。表达一种“在将来不得不去做某事”的意思。He would go into debt 则纯粹表示将来的一种不确定的结果。 will do和would do区别在于前者可能性较大且发生在现在，后者可能性较小且有可能发生在过去，是过去将来时。

哪儿没看明白接着问。追问

哇，你真厉害，解释都看懂了，谢谢你啦~
