例1 Americans eat vegetables per person today as they did in 1910.
A.more than twice B.as twice as many
C.twice as many asD.more than twice as many
思路分析:该题考查倍数表达法。其中一种方法是“倍数+as+形容词+as...”，如果形容词后带有修饰的名词，要将名词放在as...as结构的中间，形容词之后。
答案:D
深化升华 注意此处空半格英语中常用的倍数句型：
1）倍数增加
A is n times as great（long，much，...）as B.
A is n times greater（longer，more，...）than B.
A is n times the size（length，amount，...）of B.
以上三句都应译为：A的大小（长度，数量，……）是B的n倍［或A比B大（长，多，……）n-1倍］
2）倍数减少
a is n times as small（light，slow，...）as b.
