标题: 求助曼哈顿上的一个语法点，急急急！！！
Subgroup Modifiers

When you want to describe a part of a larger group with a modifier, use one of the following
three Subgroup Modifier constructions.

Right: This model explains all known subatomic particles, SOME OFWHICH
WEREonly recently discovered.
Right: This model explains all known subatomic particles, SOME OFTHEM
only recently discovered.
Right: This model explains all known subatomic particles, SOME only recently
discovered.

Notice that only the which construction has a working verb {were} in it. In contrast, wrong
answer choices often include the following three incorrect constructions, which scramble the
correct forms.

Wrong: This model explains all known subatomic particles, OF WHICH SOME
WEREonly recently discovered.
Wrong: This model explains all known subatomic particles, SOME OFTHEM
WHICH WEREonly recently discovered.
Wrong: This model explains all known subatomic particles, SOME OFWHICH
only recently discovered.

请教一下NN，后三个句子错在哪里了？谢谢

我是这么理解的不知道对不对；
首先1、SOME OF WHICH WERE不能换成 OF WHICH SOME WERE，就是说GMAT里的语法要严格的多，不能随意换句子的前后，只能是some of which 这样的顺序,不能换为 of which some were.这个记住就好啦。
2、比较正确句子的2、3, SOME OFTHEM 可以直接简化为SOME ；比较正确句子1、2,可以发现，SOME OF WHICH WERE only recently discovered. 可以为 SOME OFTHEM only recently discovered.如果用的是which的句式，必须是一个完整的句子，要有谓语were；如果用的是them，可以理解为同位语，或者是伴随，谓语就不需要了。
所以错的句子1、语序问题。2、SOME OFTHEM WHICH WERE ，又有which又有them，很明显只能选一个用，否则就混乱了，你知道他俩指代什么吗？3、用which 的话应该是完整的句子，要有谓语were。

希望对你有帮助。

Right: This model explains all known subatomic particles, SOME OF THEM only recently discovered.
这句话them不加are啊,虽然读起来好通顺阿!!!

后面是独立主格，独立主格只有句子的逻辑结构（类似主语+类似的谓语动词，通常为Ving或Ved形式）。
如果加上are，反而错了，因为此时是run-on sentence，需要conjunction连接两个完整的句子才行。
