Afica’s black rhino population in the mid-1970’s numbered about 20000,ten times the estimated population of 2000 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
B。their 指代不清, that of 无所指。 C。population 和 amount 比较了。还有一点,population‘s 和后面amount of有所有格罗嗦的嫌疑,非常wordy。 D。their。结构混乱。而且more than 不能用于比较数量吧,应该用greater· E.错误如上。 number 和number比没错,但这貌似只对population修饰,主要题干还是希望读者用population比较。ten times the N表示一种解释说明吧,作同位语之用~ A读起来就顺,又简洁。还是别总结所谓的规律帖,没意义。语法千变万化,考场上根本想不起。
