If we really know what dissapointed means英语专业老师进
If we really know what disapointed means,we wouldn,t have to make same mistake twice.
先不管总体语法,前半句 what disappointed means这个语法是正确的吧 disappointed修饰what做宾语从句主语对吧 我是这么理解的.但有同学改成 what disappointment means .
英语专业的或英语老师来说
答
简单来说 disappointment做名词 means 单三所以加sif we really knew what (it) means. 这样能看懂吧? disappointed 是形容词
