问题描述:

this is what wildlife protection is all about意思
as a result these endangered animals may even die out.they need help.this is what wildlife protection is all about.
最后一句话不明白,最好能分析一下结构!

This is what wildlife protection is all about.=This is the thing (that wildlife protectiion is all abou定语从句)
这就是野生动物保护有关的所有内容..这么说可以吗?this is that all about wildlife protection. all about的意思不是 关于...的一切?应该接在修饰词或词组的前面吗?更多见的是: That's all about wildlife protection好吧,接在is 后面应该是表语从句吧!是滴!精确讲师表语从句。干嘛用what引导,而不是that ?
wildlife protection is all about这个表达式真不习惯,干嘛这样写呢
