題目：

單項選擇：Their school is three times as ______ as ours .That means uor school is ___ than theirs.
A.big ; three times smaller
B.small ; large
C.big ; small
D.large ; twice smaller

解答：

正確的答案應該是D 這是考查倍數公式的單選題
常見的倍數考查有三種：A is +倍數+as + adj原級+B
= A is +（倍數-1）+比較級+than B
=A is +倍數+the +n.(size/weight/length/width ...) +of B
eg.The bag is three times as heavy as that one.
=The bag is twice heavier than that one.
= The bag is three times the weight of that one.
