Less than 35 years after the release of African honeybees outside Sao Paulo, Brazil, their descendants, popularly known as killer bees, had migrated as far north as southern Texas. (A) Less than 35 years after the release of African honeybees outside Sao Paulo, Brazil, (B) In less than 35 years since releasing African honeybees outside Sao Paulo, Brazil, (C) In less than the 35 years since African honeybees had been released outside Sao Paulo, Brazil, (D) It took less than 35 years from the release of African honeybees outside Sao Paulo, Brazil, when (E) It took less than the 35 years after the time that African honeybees were released outside Sao Paulo, Brazil, and then 别的选项都知道了,可答案怎么可以是A?their无指代啊。。。因为在of的后面
同理,比如, OG12- 43 Laos has a land area about the same as Great Britain but only four million in population, where many are (C) that is about the same size as Great Britain’s land area, but in Laos with a population of only four million people, many of them 指代不清
og-12-23 In a previous design, the weight of the discus used in Track competition is concentrated in a metal center,but now it is lined with lead around the perimeter 指代不清

我没理解their为啥在of后面就不能指代了。。。很明显their是指代的African honeybees. 无论是否是A of B的结构,their只能知道一个复数名词,对于他是处于介词短语的A位置还是B位置是没有要求的,也就是说,A如果是复数,thier可以指代A。A如果是单数,B是复数,their也可以指代B。但是A B都是复数,则their指代不清楚。
OG12- 43 Laos has a land area about the same as Great Britain but only four million in population, where many are (C) that is about the same size as Great Britain’s land area, but in Laos with a population of only four million people, many of them 指代不清 这里首先套用了一个th same as的比较 比较对象是the land area 是需要一致的。C选项中的them指代是people啊。因为只有people这一个复数名词啊。。。没有其他的复数名词了 。
23 In a previous design, the weight of the discus used in Track competition is concentrated in a metal center,but now it is lined with lead around the perimeter 指代不清
这里it 的指代是不清楚的。因为这里有两个单数名词,weight 和 discus就是刚刚我说的A of B AB单复数无区分的情况,it指代就是不清楚的。而正确选项中, Once designed with its weight concentrated in metal center, the discus used in track competition is now lined with lead around... it很明显只能指代他的逻辑主语,因为在it之前只有一个单数的逻辑主语discus可以指代。虽然因为句子结构的原因并没有显示出有discus。
以上个人意见,欢迎指正。 |
