225. Minnesota is the only one of the contiguous forty-eight states that still has a sizable wolf population, and where this predator remains the archenemy of cattle and sheep.fficeffice" />

(A) that still has a sizable wolf population, and where

(B) that still has a sizable wolf population, where

(C) that still has a sizable population of wolves, and where

(D) where the population of wolves is still sizable;

(E) where there is still a sizable population of wolves and where

Choice D is grammatically constructed, but it lacks a conjunction that establishes a logical relation between the clauses; since Minnesota as a grammatical subject is separated from the clause following the semicolon, the statement there need not even pertain to Minnesota.

    这段解释是什么意思阿

那  where there is still a sizable population of wolves, and where this predator remains the archenemy of cattle and sheep  加个逗号是否对?

本人看法:

加了逗号后面的WHERE就是状语从句,就导致与前面定从的不平行,即使前后都是WHERE,不加逗号则是两个定从的平行,正确.望指正..

Choice D is grammatically constructed, but it lacks a conjunction that establishes a logical relation between the clauses; since Minnesota as a grammatical subject is separated from the clause following the semicolon, the statement there need not even pertain to Minnesota.

选项 D 语法正确，但是与原因间的表述没有逻辑关系； 由于 语法主语Minnesota 与其修饰从句被分号分开，使得句子和 Minnesota 不大相关。

白话：按照 D ，this predator remains the archenemy of cattle and sheep 是独立句子，和其要修饰的逻辑成分Minnesota无关了。

但是， where there is still a sizable population of wolves and where this predator remains the archenemy of cattle and sheep 都是修饰 Minnesota 的。

怎么排除的?

我认为根本没有道理，不可能排除。and 是连词，连接几个并列的成分时，其前通常既可以有逗号，也可以没有。都是对的。

引自GWD语法笔记，看似能解决此题争议，排除ABC，不知有没有人见过“l 二重并列不能用逗号 的

并列的解题步骤：
   

并列的含义：所有的有对应关系的都叫并列，包括同位语，独立主格，and，or连接的两个纯并列句不考虑，但是and,or连接的并列结构属于并列, but 连接的前后两部分要完全对应(but是取非的意思)

l 谁和谁并列（看结构功能是否对应）
   

l 二重并列不能用逗号
    

l 三重以上只能用and, or 引导，其他都不行，并列只能在最后用逗号＋and

l 两个句子中间要用“and”连
   

l 对于具体词，只要不是自己和自己比就不能用it（虚词除外，例如通货膨胀）
