问题补充：
his spare time that his English has improved a lot.
A. So good use does he make of
B. Such good use does he make of
C. He makes very good use of
D. He makes so good use of
答案：
A. So good use does he make of
(答案→)B. Such good use does he make of
C. He makes very good use of
D. He makes so good use of
解析：考查such---that句型及make use of 短语的变化。句意：他的空余时间是利用的如此的好，以至于他的英语提高很多。这里使用such…that…句型，而且是make use of这个词组的被动语态，so修饰的是形容词或副词，这题修饰的是good use，用such，such good use 放在句首的时候，句子用部分倒装，选B.
