prep解释上面说D选项逻辑主语不对，请问在D选项中的逻辑主语是什么。。。（求轻拍。。。）还有，with引导的独立主格怎么判断逻辑主语。。。。（是不是我逻辑太差，总是判断不好逻辑主语。。。）

哎呀， 问问prep解释中说“a fact无所指”。请问“a fact”不能指代前面的“some fraternal twins resembling each other greatly and others looking quite dissimilar”这件事么？谢谢~

嗯，怎么说呢，我觉得这句话的主语就是some fraternal twins resemble each other greatly and others look quite dissimilar. D选项把主语变成伴随成分了，不再是主句的一部分了。
with在这句话里找不到逻辑主语。。。。。
a fact 在这里不能像你这么说的指代，with是伴随成分、修饰成分，一般是不会在主句中代指的
某种情况下，a fact 应该是可以代指some fraternal twins resemble each other greatly and others look quite dissimilar：1，做同位语： scientists found out that some fraternal twins resemble each other greatly and others look quite dissimilar, a fact that highlights an interesting feature.
                      2, 避免重复原话，为了简练而代指： scientists found out that some fraternal twins resemble each other greatly and others look quite dissimilar. This fact highlights an interesting feature.
                      3, 为了避免歧义而代指：这个我就不会举例了，但是很常见，在it或者they之类的代词存在指代模糊问题时，用概括性或者同义词指代。

这里都不满足

谢谢你的回复，基本都看懂了，也明白D是怎么错了。但是我还是想问问，with引导的独立主格怎么判断逻辑主语？谢谢

嗯。。。。我有点不知道怎么说。。。。。给我例子我能分析，这么总结我就有点不会了
真要说，就是看句子的意思
with的意思：“随着”或者淡淡的“因为”
套在句子里翻译过来，感觉没错就行

谢谢啦~超级热情，还想问一下，是不是each引导的独立主格修饰的是each前面紧跟着的那个词，而with引导的独立主格是修饰逻辑主语的？谢谢~

1、with独立主格结构自带主语，它的逻辑主语就是“独立主格”啊。

GWD-TN7-3：With the cost of wireless service plummeting in the last year and mobile phones becoming increasingly common, many people are now using their mobile phones to make calls across a wide region at night and on weekends, when numerous wireless companies provide unlimited airtime for a relatively small monthly fee.
红字就是with结构主语。

2、只有没有主语的modifier才需要找逻辑主语。
