A.   The fact of some fraternal twins resembling each other greatly and others looking quite dissimilar highlights an interesting and often overlooked feature of fraternal-twin pairs, namely they vary considerably

B.    That some fraternal twins resemble each other greatly while others look quite dissimilar highlights an interesting and often overlooked feature of fraternal-twin pairs, namely that they vary considerably

C.   With some fraternal twins resembling each other greatly and others looking quite dissimilar, it highlights an interesting and often overlooked feature of fraternal-twin pairs, namely considerable variation

D.   With some fraternal twins resembling each other greatly and others looking quite dissimilar, it is a fact that highlights an interesting and often overlooked feature of fraternal-twin pairs, namely a considerable variation

E.    Because some fraternal twins resemble each other greatly and others look quite dissimilar, this fact highlights an interesting and often overlooked feature of fraternal-twin pairs, namely they vary considerably

答案B   不过时态不对称!! D哪不对....NN指点一下吧,最好能把5个选项都分析一下..急

A 不对，首先，fact 和后边的“some fraternal twins resembling each other greatly and others looking quite dissimilar”指的是同一样事情，不是从属关系，不能用fact of (......的事实）这样汉语化的理解。其次，some fraternal twins resembling each other greatly 和others looking quite dissimilar意思不是并列的，而是对照的，有强烈的反差感，因此，它们之间不能用and 来连接。

C和D 两个选项都用了with 词组 和it 做主语，本身就有问题。with 词组放在句首，除了“伴随着....."意思之外，就是“有......的特性”或者“有......的东西”，而动作者就是紧跟着的主句中的主语。在C、D中，It 指代都不明确。更不知道with词组修饰所指了。和有其他的语法错误，不一一罗列。

E 彻底改变了原句的意思，句子重心转移。因此，第一个排除的就是E

感谢楼上的解释!!!

对and  while  yet有变化的题目一直没感觉...有什么好办法吗
