答案:E
请问其他选项被排除的原因之一是否是这几项中study动作的执行者错误呢?
如果 D 改成
By studying the fruit fly, a household nuisance but a time-honored experimental subject, scientist begin to unravel the secrets of how embryos develop.
是否就比E更好呢?
1. 是的
2. 你改过的D,By studing ..., scientists begin ... 强调的重心是 scientists 如何如何。 E 强调的是 the study 的功能如何如何。不过,你改过的 D 结构更清晰了。
E) The study of the fruit fly, a household nuisance but a time-honored experimental subject, has enabled scientist to begin to unravel the secrets of how embryos develop.
我想请问下黄标的内容什么意思了?作为什么成分啊?是绿标的同位语吗?请教
D这样改逻辑主语还是有些模糊。。
