Mary’s house in Shanghai cost much more than ours in our hometown, though not half .
A. much bigger
B. as bigger
C. very big
D. so big

A. much biggerB. as biggerC. very big(答案→)D. so big解析：考察倍数表达法。本句是一个省略句，后面省略了as our house。倍数表达有四种：1. “A+倍数+形容词或副词的比较级+than+B”， 2.“A+倍数+as+形容词或副词的原级+as+B”， 3. “A+倍数+the size/height/length/width， etc+of+B”， 4. “……times+what+从句”。本题考察了第二种，half 也是倍数。因为本句是一个否定句，所以使用so…as…；句意：Mary在上海的房子比我们家乡的房子更值钱，尽管还没有我们家里的房子的一半大。故D正确。
