关于what引导的宾语从句做主语的问题
A modern city has been set up in what was a wasteland ten years ago.这句话我有好多疑问不解
第一,what引导的宾语从句,我觉得怎么不可以在哪里建立的呢?怎么区分宾语和状语?我把what引导的句子拿去也通顺啊,一座现代城市被建立,怎么就不可以说是确定set up的状语呢?
第二,都说宾语从句用陈述语序这里怎么不是?what was a wasteland.
第三,能否多给几个关于what引导宾语从句做主语的例子.
第四.Can you tell me "what is English?"变成间引就是Can you tell me what English is.真的是不清楚了

what在高中阶段,需了解几个含义:
1what= the thing (that...)
You can take what you like.(=You can take the thing that you like.)
2.what=the person.(that.)
Mary isn;t what she used to.(=Mary isn't the person that she used to.
3.(in/at) the place (that.)你的句子等于:
A modern city has been set up in the place that was a wasteland ten years ago.
第二问题想必你理解了吧.
第三太多了
(What he said/bought/wanted/found/did 主语) surprised us greatly.
第四问题
宾语从句除了what's wrong with.../ what's the matter with/ what's the trouble with..不改变语序外,其余均要改成陈述句式.
