(24630-!-item-!-188;#058&001004) (GWD-24-34)[E1] E Studying the fruit fly, a household nuisance but atime-honored experimental subject, has enabled the secrets of how embryosdevelop to begin to be unraveled by scientists. A.Studying the fruit fly, a household nuisance but a time-honored experimental subject[E2] , hasenabled the secrets of how embryos develop to begin to be unraveled byscientists. B.By the study of the fruit fly, a household nuisance and also a time-honored experimentalsubject[E3] , it waspossible for the secrets of how embryos develop to begin to be unraveled byscientists. C.By studying a household nuisance but a time-honored experimental subject, the fruit fly[E4] enabledscientists to begin to unravel the secrets of how embryos develop. D.By studying the fruit fly, a household nuisance and also a time-honoredexperimental subject,the secrets[E5] of howembryos develop are beginning to be unraveled by scientists. E. The study of the fruitfly, a household nuisance but a time-honored experimental subject, has enabledscientists to begin to unravel the secrets of how embryos develop 首先，这道题选E，应该不会有太大的疑问，但是我的疑惑来自于选项B。只看B选项的后半句的话，的确很容易判断出来B是错误，非常糟糕的表达，但是如果看前半句呢？坛子里面有人认为：a household nuisance and also a time-honored experimentalsubject是做同位语，由于同位语一般是对名词进行进一步的解释，但是这句话的开头是一个介词短语，By the study of the fruit fly所以错误了。但是我认为，很明显这个同位语是解释的the study of the fruit fly，这一点应该是没有错的，前半部分真正的错误应该是后面的主语是it，it不能和by the study of the fruit fly来搭配，而且it到底是指谁，这句话里面也说不清楚，至少应该是scientists才能by the study of the fruit fly吧？ 这是我个人的理解，不知道对不对，置换达人解答！ 作者: ericgong1982 时间: 2010-5-13 22:47

it 指代 to begin to be unraveled 这不很明显的么
