As we have known from the map of the world，this is ________.
A．twice as large an island as that
B．twice as large as that island
C．as twice large as that one
D．twice as a large island as that
答案
答案：A
考查倍数表达. 正确结构应该是：倍数 as adj+n as ；第一个as是副词，所修饰的形容词要紧跟在它后面，形容词所修饰的名词要跟在形容词的后面。所以应该使用：as large an island as。句意：正如我们从地图上所看见的一样，这是一个比那个岛大两倍的岛屿。
