题目分析:
本题OG的解释是有些问题的(不能说它错,但是不具有推广性),不建议大家学习。(A)(B)中的having hundreds of eyes可以看作伴随状语,也可以看作the compound insect eye的非限制性定语。(C)(D)(E)中的its是所有格的代词,其应该指代一个在逻辑上和单复数上均合理的名词,并不一定要指代核心词。因此,我们可以理解为,五个选项中拥有数以百计的小眼睛的均是昆虫的复眼(the compound insect eye)。
选项分析:
A选项:主谓不一致。help explain的主语的核心词是structure,是单数,所以help explain应该改为helps explain。
B选项:最后一个词代词they的指代对象有问题。they只能指代复数名词,所以本题中只有复数名词scientists是可以被指代的。但是,在逻辑上,能独立于脊椎动物的眼睛进化的肯定是某种眼睛,而不是科学家。
C选项:本选项最后的代词they的指代对象错误同(B)。
D选项:主谓一致错误同(A)。
E选项:Correct.本选项在语法和逻辑上均没有错误。with its hundreds of miniature eyes called ommatidia是一个独立主格结构。
it evolved independently of the vertebrate eye
they = can refers only to "miniature eyes"
it = can refers to "compound insect eye"
相对于vertebrate (脊椎动物)eye,应该指代 "compound insect eye"
