40. Dr. Tonegawa won the Nobel Prize for discovering how the body can constantly change its genes to fashion a seeming unlimited number of antibodies, each specifically targeted at an invading microbe or foreign substance.
(A) seeming unlimited number of antibodies, each specifically targeted at
(B) seeming unlimited number of antibodies, each targeted specifically to
(C) seeming unlimited number of antibodies, all specifically targeted at
(D) seemingly unlimited number of antibodies, all of them targeted specifically to
(E) seemingly unlimited number of antibodies, each targeted specifically at

关于D 选项 OG上说all用的不对,我理解antibodies后面的句子是antibodies的同位语,那antibodies是复数形式,后面用all 不比each好吗?
这个each我反而有点不懂!求教!!!

each 形式的独立主格,前面一定是一个复数名词才行噢,所以“antibodies是复数形式,后面用all 不比each好吗?”这种问题不存在

这里all 跟后面 an invading microbe or foreign substance 不搭,应该是每一个**对应一个***,而不是所有的***对应一个***

此处是each的独立主格。each的独立主格在句中通常位于句末,因为each在指前句中的某个名词,此处指的是antibodies,通常在最后一个,其用法的一般形式为:S v O, each doing/ done/ prep+n/adj+ prep+n/n,此题用的是each done的那种用法。(SVO代表主谓宾)。
而且根据句意也不应该用all。的确前面antibodies是复数,但划线后面是an invading microbe or foreign substance,是单数,你不觉得所有抗体去瞄准一个入侵的外来异物不大对吗?用each就合理多了吧,每一个抗体target at an invading microbe or foreign substance.

关于adv. 的位置

还有就是我刚刚看到一个帖子专门提到了说E里头的specially位置变化了是因为强调的point有变化。但是不是adv.放前放后都ok的么?我给绕进去了……求指教!谢谢!
