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
我选的是B 因为我觉得10times前面的是数字, 所以比较前后对等的话后面不是也应该是一个数字吗(人口的数字)
还有我记得之前og上也有一道类似的题那湖和淡水量直接比。。。。。湖和淡水量可以比吗。。。。哎。。。越来越晕了 |
