标题: 问题请教 [打印本页] 作者: cderfrank 时间: 2013-4-20 17:01 标题: 问题请教 Schistosomiasis, a disease caused by a parasitic worm, is prevalent in hot, humid climates, and it has become more widespread as irrigation projects have enlarged the habitat of THE FRESHWATER SNAILS THAT ARE THE PARASITE'S HOSTS FOR PART OF ITS LIFE CYCLE.
A. the freshwater snails that are the parasite's hosts for part of its life cycle
B. the freshwater snails that are the parasite's hosts in part of their life cycle
C. freshwater snails which becomes the parasite's hosts for part of its life cycles
D. freshwater snails which become the hosts of the parasite during the parasite's life cycles
E. parasite's hosts, freshwater snails which become their hosts during their life cycles
问题:题目中的红色的it代表的应该是parasitic worm吧?如果是这样的话,这个指代会不会引起歧义,会不会让别人理解成schistosomiasis?如果这里不是指代parasitic worm的话,我很难理解题目中的for part of its life cycle.另外,答案说B中的in part of their life cycle中的In使用的不正确,想问问大家为什么不正确?
谢谢!作者: 郁离 时间: 2013-4-20 17:27
这里的it应该是指代schitosomiasis,因为是由and连接的并列句,句首代词应该优先指代并列句同等地位和功能的名词,也就是前一句句子的主语;
并且句意也讲得通:“因为水利项目扩大了(致病的)寄生虫宿主的habitat,疾病广泛传播“。作者: cderfrank 时间: 2013-4-20 18:30
