The skin of the poison dart frog contains deadly poisons called batrachotoxins. But the (i)________ of the toxins has remained an enigma, as the frog does not (ii)________ them. Now an analysis suggests that the melyrid beetle is the source. Collected beetle specimens all contained batrachotoxins, suggesting that these beetles are (iii)________by the frogs.
Blank(i) Blank (ii) Blank (iii)
A. effect D. pressure G. eaten
B. origin E. produce H. neutralized
C. purpose F. suffer from I. poisoned
选项
答案
B,E,G
解析
空格(i)(ii):
- 方程等号:the定冠词,同义重复。
- 强词和对应:第三句话说“现在一个分析指出melyrid甲虫是这种毒素的来源”。根据正向的方程等号the可知,the后面的名词source来源,一定在前文当中出现过。据此空格(i)和空格(ii)可以同时选出答案。effect作用,origin来源,purpose目的,pressure压迫,produce产生,suffer from受苦于,只有BE选项含有“来源”的意思。故空格(i)选B,空格(ii)选E。
空格(iii):
- 方程等号:句号,同义重复。
- 强词和对应:根据句间关系,第四句话之前的部分说的是“毒箭蛙本身不产生毒,毒箭蛙的毒是来自melyrid这种甲虫。”那么根据正向的方程等号句号,第四句话应该也描述相类似的意思。eaten被吃掉,neutralized被中和,poisoned被毒害,填入eaten之后句子意思是“被收集起来的甲虫标本都含有batrachotoxins这种毒素,这就表明这些甲虫被青蛙吃掉了”,这样就能够清楚地说明毒箭蛙的毒素是如何产生的,故选G。
