再再问OG-208 --- 语义逻辑

fychen66

Teratomas are unusual forms of cancer because they are composed of tissues such as tooth and bone not normally found in the organ in which the tumor appears.

(A)  because they are composed of tissues such as tooth and bone

(B)  because they are composed of tissues like tooth and bone that are

(C)  because they are composed of tissues, like tooth and bone, tissues

(D)  in that their composition, tissues such as tooth and bone, is

(E)   in that they are composed of tissues such as tooth and bone, tissues

看过先前的讨论和OG的解释也知道了in that 和 because的区别，以及加不加tissue的区别。可是有个问题还是很困惑：为什么不加tissue会导致逻辑错误？不加tissue的意思成了tooth and bone not normally found in the organ

加了tissue成了tissue not normally found in the organ。可是tissues和tooth and bone本来就有着tissues such as tooth and bone的关系，为什么就不能tooth and bone not normally found in the organ 呢？各位NN你们是怎么判断这个逻辑的啊？可能是我的脑子短路了！

谢谢

只有tissue才可能出现在organ里, bone怎么可能出现在organ里.

还是没明白。有谁能帮着再解释一下？

tissues such as tooth and bone不就是说这些tissue就是tooth and bone吗？哪tissue not normally found in the organ和tooth and bone not normally found in organ有什么区别呢？

这是个局部句意的问题吧。 tooth and bone 是举例说明tissue,他们是tissue的一种, tissue还有很多其他类型吧可是句意是要表明tissue这个大类别not normally found in organ. 如果没有tissue 意思就变了 而且, in that 从句中的宾语是tissue, 后面not normally...成分是要修饰tissue的. 因为有了 such as t&b, 避免歧义要再次出现tissue
