还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
看到题目的时候我想fail这里是外延内涵。当时我认为是fail这个行为必然有一个终点的，不然不会被起诉，所以我选择B。
在看到答案的时候我只能通过说 律师起诉的是一个行为，这个行为一直存在，所以说是没有终点的-ing或者that。
我不确定这样是否正确，请指正
虽然我也做错...选B，但是仔细想想failure of/in sth.好像sth都是名词或者名词短语啊，没见过failure of doing sth...的，接谓语的都是fail to do sth.
此外by后面是不是一般都是doing sth....也没有见过by sth.(一个名词)，除了by sea, by air 之外的
唉。。但是这个用固定搭配来选择。。。其实心里不是特别有底……
哈哈哈哈哈 希望有大佬提出更好的解题思路
也许是fail的约束力强，宾语跟to do；its重复的也很频繁
这道题目我还是想不通。。是否因为是by+doing是指通过一个手段？
请问合格外延内涵的知识点在哪里可以查看哦？谢谢
