问题补充：
that he was praised by his teachers.
A. So great progress had he made
B. So great progress he had made
C. Such a great progress had he made
D. Such great progress had he made
答案：
A. So great progress had he made
B. So great progress he had made
C. Such a great progress had he made
(答案→)D. Such great progress had he made
解析：考查倒装句型。在英语中将so，such和修饰的词放在主语的位置，主句要部分倒装，be动词，情态动词和助动词放在主语前面。Progress是不可数名词，用such修饰，也不能加a，句意：他取得了这么大的进步，以至于受到老师的表扬。另外考虑用一般现在时，选D。
