66. (28087-!-item-!-188;#058&003498)

Africa's black rhino population in the mid-1970's numbered about 20,000, ten times the estimated population of 2,000 in 1997.

(A) the estimated population

(B) that of their estimated population

(C) more than the population's estimated amount

(D) more black rhinos than their population estimate

(E) more than that of their population's estimated amount

答案：A

对于数字比较总是晕

more than是改变原文意思么

ten times 不能与more than连用

可不可以像数学一样理解为ten times是倍数的关系 more than是加法的关系？

我倒是认为，这题应该是比较对象的问题，应该是population 和 population 比，population 不能同population's estimated amount来比，这样就只有A对了，顺便说句这题中B,C,D中their都没有指代对象
