his work was still as it had been ?
A.Itwas why that B.Why is that C.It is why that D.Why was it that
老师：答案选D.
Whywas it that his work was still as it had been ?
=It was why that his work was still as it had been - 这是强调句。
=Why his work was still as it had been ?
= Why was his work still as it had been ?
其实，刚开始的原始句就是 Why washis work still as it had been ? 吗？
1）但，为何网上都如此说：“其中it为形式主语，真的的主语是that his work was still as it had been。故选D，考试知识点：固定句型的使用方法。“ 搞不懂了。
2）另外这里的still as it had been - 如何剖析语法成分，整个是作谓语was的表语吗？
1. Why was it that his work was still as it had been ? 这是正宗的强调句，为特殊疑问句形式。它是否强调句，看答语便知：
It was because of his illness that his work was still as it had been. （被强调成分是 because of his illness）
2. Why his work was still as it had been ? （误，语序错误）
Why was his work still as it had been ? （正，普通的特殊疑问句）
3. as it had been 作 was 的表语从句。
