答案给的是B，之所以没提前给答案，是因为怕大家根据答案反推出理由，没有意义了。。

是选B，请问看的头大时，阁下是怎么海里捞针把答案搞出来的。。。

啊估计你么有看到我 编辑过的。
=。=我做语法就是先读懂句意。你是不是选的A呀？
THAT在这里引导主语从句
A  of---that 就OK
C  D with 改变句意了，it无指代 重心转移
E  逻辑意思怪怪的 不能说因为这个XXX然后就highlights吧  只是阐述一个事实 原意中么有because的含义
再有 Namely 是个副词 后面的如果不要that 就是个句子 从某种意思上来说 缺少连词。

anyway 还是从句子意思出发哦。我读下来就B 表达的最好
嘿嘿
很久不看G了  说得不好 望大牛指教

考点：
1.    one与another搭配；some和others搭配；each和the other搭配；each other和others搭配
2.    namely是的用法十分灵活：（=that is to say, along with）.它是副词，后面不能直接加句子
（1）补充说明前面离它最近的名词成分；e.g.: The other change, namely the increase in electronic equipment, has slowed down.
（2）补充说明句子主语；e.g.：One group of people seems to be forgotten, namely pensioners.
（3）namely后面跟从句解释前面的名词成分；e.g.: On the next trip, I solved part of the problem, but after discussing the situation with AB on the phone an alternative solution was at hand; namely, that from 1987 onwards I would spend my winters playing for Queensland.
选项分析：
A．    the fact后面用of无法完全解释fact的内容，应该用that引导的同位语从句，来说明twins发生了什么fact(更多详见补充)；namely是副词，后面直接加句子错，应该加上连词that；
B．    Correct；namely that修饰that引导的名词性从句(名词性从句相当于名词)，根据这一点可以迅速排除C,E个选项。本句是namely上述的第2种用法，本句亦可调换顺序改为第一种用法：That some fraternal twins resemble each other greatly while others look quite dissimilar, namely that they vary considerably, highlights an interesting and often overlooked feature of fraternal-twin pairs.
另外，"namely that they vary..."和"namely considerable variation"都是没有问题的，这一点直接排除A,E，留下B,C,D。
C．    It无所指；with独立主格做伴随状语，其所修饰的主语必须能够“被伴随”，而在此it逻辑意思上无法“被伴随”；variation与feature并不对等，因此namely无补充说明对象。
D．    It指代正确，因为是结构it is a fact that结构的一部分，强调句；a fact无所指；with独立主格错误同C；namely无补充说明对象。
E．    Because引导的是原因状语从句，而并不是名词性从句，使得this fact无所指；namely后应该加上that。
