Although “all the proceedings of the Communist party conference held in Moscow were not carried live”,  Soviet  audiences have a great deal of coverage.
(A)all the proceedings of the Communist party conference held in Moscow were not carried live
(B)all the Communist party conference’s Moscow  proceedings were not carried live
(C)all the Communist party conference Moscow  proceedings have not been carried alive
(D)not all the Communist party conference Moscow  proceedings have been carried alive
(E)not all the proceedings of the Communist party conference held in Moscow  were carried live.
答案E。书上解释是：“not 是修饰all的，却被放在谓语部分去修饰谓语动词，位置不恰当。”
可是请大家看这道例句：
All his children are not at school。（他的有些小还在小学，言下之意，有些没在上学。）见LZM page217
当not和all, both, everyone, everything一起连用时，不表示完全否定，仅表示部分否定；表示全部否定要用neither, nor, nothing。
答案E当然是没有问题的，要不是被书上这么一提醒这个语法点的话，我闭上眼睛都知道是E，可是这个语法点不就是说明了A应该也是对的吗？
Archaeologists in Ireland believe that a recently discovered chalice, which date from the eighth century, was probably buried “to keep from “being stolen by invaders.
“to keep from” or “to avoid”？为什么？

Never before in the history of music have musical superstars been able to command “so extraordinary fees of the kind they do today”.
答案：Such extraordinary fees as they do today
这是一个考比较的句子，比较前的是musical superstars have been able to command…，比较后是they do，但是我觉得这里应该用are，因为前面是be able to command。但答案的解释说是应该跟command比较，这让我糊涂了。。。请个位赐教。

attempt表示是所有tissue组织中的enzymes所共有的性质，是整体用单数。OG和大全中都有例子：

1. Neanderthals had a vocal tract that resembled those of the apes and so were probably without language, a shortcoming that may explain why they were supplanted by our own species.

(A) Neanderthals had a vocal tract that resembled those of the apes

(B) Neanderthals had a vocal tract resembling an ape’s

(C) The vocal tracts of Neanderthals resembled an ape’s

(D) The Neanderthal’s vocal tracts resembled the apes’（B）

(E) The vocal tracts of the Neanderthals resembled those of the apes

The sentence requires a subject appropriate to both members of a compound predicate, the second member being and so were probably without language. B, the best choice, logically uses Neanderthals as the subject. Choice A also uses this subject, but the plural pronoun those does not agree with its singular antecedent, a vocal tract. C, D, and E present the inappropriate subject vocal tracts, which cannot logically govern the second member of the predicate (i.e., vocal tracts cannot be said to be without language). Moreover, it is better to use the singular in referring to an anatomical feature common to an entire species; C, D, and E use the plural vocal tracts. D compounds the problem by giving multiple vocal tracts to one Neanderthal.

Unlike other arachnids, which have their nerve cells evenly distributed along their bodies, the scorpion’s nerve cells are clustered in its head, like a mammal’s.

(A) bodies, the scorpion’s nerve cells are clustered in its head, like a mammal’s

(B) bodies, the scorpion’s head had a cluster of nerve cells, as a mammal does

(C) body, the scorpion has a cluster of nerve cells in its head, as a mammal does

(D) body, nerve cells are clustered in the scorpion’s head, like a mammal’s（C）

(E) body, a cluster of nerve cells is in the scorpion’s head, like a mammal’s

我认为A，E语法上没什么问题，那就要看句子的意思了，一个是部分否定，一个是全否定，要根据意思来选了。
