问题补充：
houses were knocked in the earthquake.
A. A great many of
B. The number of
C. A great number of
D. Amounts of
答案：
A. A great many of
B. The number of
(答案→)C. A great number of
D. Amounts of
解析：考查词组辨析：句意：大量的房子在地震中被推倒。当a great many后的名词不是特指,即没有the,these,those,my等限定词时,不用of,否则就得用of. 所以A不行，The number of.....的数量(后面加单数谓语，）所以B不对，Amounts of+不可数名词，谓语是复数，所以D不对。a number of +不可数名词复数，谓语也是复数，选C。
