Question

As we have known from the map of the world, this is ______.

A．twice as large an island as that	B．twice as larger as that island
C．as twice as that one	D．twice as a large island as that

Answer 1

A

试题分析：考查倍数：倍数+as+adj+an/a+名词as，先是twice，然后是as +形容词（large）an island +as…,句意：从世界地图上我们可以看出这是那个岛两倍的岛屿。选A。
点评：倍数表达要牢记，倍数表达法是高中英语教学的重点，也是历届高考的热点。当我们要表达甲是乙的几倍时，通常用句型来表示： “A+倍数+形容词或副词的比较级+than+B”，表示“A比B大（长、高、宽等）多少倍”。2.“A+倍数+as+形容词或副词的原级+as+B”，表示“A正好是B的多少倍”。 3. “A+倍数+the size /height /length /width，+of+B”，表示“A正好是B的多少倍”。4.“……times+what+从句”。还要特别注意：as/how/so/too这几个词都是先加adj再加冠词然后是名词的搭配。
