My hometown has expanded in the past 10 years with a population___what is used to be
A 3 times as big as B as 3 times big as
C 3 times as much as D 3 times more than
为什么我感觉四个选项都不对呢.
population不是应该用"large”修饰吗?
请教.
答：A
分析：Population有两义：
1.number (of people) :The population of the town is large/ big/ small /300,000.
2.people:Two thirds of the population of the town are farmers.
这里的population因前面有个a,所以= number
A 是B的 几倍（大、高、重）的表达法：
A is 倍数+ as +adj.原级+ as B
A is 倍数+ adj.比较级+ than B
D.项结构正确,但more是many 或much的比较级,而一个数字的大、小用形容词large/ big 和small,故排除D.
C项结构正确,但形容词错,排除.B项形容词正确,但结构错误,排除.
只有A,形容词正确,结构正确,
