[交流] 关于两句文献英语中which的用法，求详解。

All T cells come from progenitor cells from the bone marrow which become committed to their lineage in the thymus.

上面这句的which是指代什么？为什么不用“，”分开？这样表达不会引起歧义么？这个是which的哪种用法？

All T cells begin as CD4-CD8-TCR- cells at the DN (double-negative) stage, where an individual cell will rearrange its T cell receptor genes to form a unique, functional molecule which they in turn test against cells in the thymic cortex for a minimal level of interaction with self-MHC.

这个话的which我就更看不懂了这个which又是指什么，也没用“，”分开。

求这两句的语法详解，请标注主谓宾，和说明which的用法，非常感谢！

20金币答谢。

houjinglhy(金币+2):似乎有点道理 2010-07-11 19:08:07

A simple way to answer your question is to rewrite the sentence into some simple sentences, but I doubt whether you can do that as it seems that you quite don't understand the original sentence as I do.

That's quite normal, as the original one MAY not be a correct one in terms of gramma. For example, if someone say "the former 3 stations ...", how could you explain the English usage of that phase when it is wrong?
