我不太理解这句话的存在形式 是省略句吗?还是什么.

go,就是说的意思.
standard response goes,go,就是说的意思.
The satnadard repsonse says that shis cannt be true.
以下,可能是出处.
Many people say that the second option is more likely.(Yet,the standard response goes,this cannot be.)The rules of probability tell us the probability that both A and B are true cannot exceed the probability that either A or B is true.It is less likely that someone is a female Jamaican Olympic gold medalist than that a person is female,or that a person is Jamaican,or that a person is a gold medalist.Yet even people trained in probability make a mistake with the Linda problem.02 Or is it a mistake?Little introspection is required to understand what is going on.Respondents do not interpret the question as one about probability.They think it is a question about believability.

The standard response goes, this cannot be.
意思是 标准的回答是行得通的，但这个回答不可能是标准答案。
完整的句子是 The standard response goes, （but） this cannot be （the standard response）.
括号里的成分被省略了~~
谢谢采纳，欢迎追问！感谢您的帮...

你翻译的不对，正确的翻译是 “标准答案却并非这样” 他不是一个省略句， “this” 代表 前面的“The standard response”
