一道英语语法题

Question

Overpopulation poses a terrible threat to the human race.Yet it is probably____a threat to the human race than environmental destruction.
A.no more B.not more C.even more D.much more
请问为什么选B，后面a threat 不是名词么A为什么不对。语法点是什么

Answer 1

1. no more than 表示“仅仅”、“只有”(= only)，强调少；而 not more than 表示“不多于”、“至多”(= at most)。如：
He is no more than an ordinary English teacher. 他只不过是个普通的英文老师。
He has no more than three children. 他只有 3 个孩子。
He has not more than three children. 他最多 3 个孩子(有或许还不到 3 个之意)。
2. 用于比较两件事物时，no more ... than 表示对两者都否定，意为“同……一样不”(＝neither ... nor)；而 not more ... than 指两者虽都具有某种特征，但程度不同，意为“不如”、“不及”(= not so ... as)。如：
He is no more a writer than a painter. 他不是画家，也不是作家(= He is neither a painter nor a writer)。
A whale is no more a fish than a horse is. 马不是鱼，鲸也不是鱼(=Neither a horse nor a whale is a fish)。
She is not more clever than he is. 她不如他聪明(= She is not so clever as he is)。

Answer 2

no more =not more than....后面有than了，所以A不对。
还原一下： A threat to the human race is not more than environmental destruction.
it 这里替代 A threat to the human race,因为它太长了。追问

那么A threat to the human race is no more environmental destruction这样可以？

Answer 3

no more than的意思是“只不过”，
not more than的意思是“不多于”

Answer 4

no more 没更多。not more没有更多的 语法it is做强调。强调没有更多的什么

Answer 5

答案：A
解释：这里是及物动词hide的过去分词，表示句子的主语I（我）是过去分词hidden的承受者。非谓语形式。完整的句子是：As I was hidden behind the door,I wasn't found by the fellow.
翻译：由于我藏在门后面，我没有被那家伙发现。
提示：过去分词作状语，句子的主语是分词动作的承受者；现在分词作状语，句子的主语是分词动作的执行者。
例如：Waiting for a bus,I saw Jack.句子的主语I(我)是现在分词waiting的执行者。“等公交车的时候，我看见了杰克。”这个句子等于“While I was waiting for a bus,I saw Jack.”
学习要点：英语中这几个词必须弄清楚：seat,hide,lose,dress,他们的句型是：seat oneself ,hide oneself ,lose oneself,dress oneself.
帮助理解：I seatd myself.=I was seated. I hid myself behide the door.=I was hidden behind the door. I lost myself in the forest.=I was lost in the forest. I dressd myself in red.=I was dressed in red.
延伸理解：As she was dressed in red,she could easily be found.=Dressed in red,she could easily be found.句子的主语she是dress动作的承受者。As she was dressed in red,=As she dressd herself in red,。
