Over the next few years, increasing demands on the Chattahoochee River, which flows into the Apalachicola River, could alter the saline content of Apalachicola Bay, which would rob the oysters there of their flavor, and to make them decrease in size, less distinctive, and less in demand.
which would rob the oysters there of their flavor, and to make them decrease in size
and it would rob the oysters there of their flavor, make them smaller
and rob the oysters there of their flavor, making them decrease in size
robbing the oysters there of their flavor and making them smaller
robbing the oysters there of their flavor, and making them decrease in size
题目分析：
本题描述的是：上升的需求改变了Apalachicola Bay的含盐度，所以夺去了牡蛎的味道并且让它们的变得更小了。
选项分析：
A选项：本选项中which would rob是定语从句，定语从句具有就近修饰原则，即，其修饰一个最近的名词—Apalachicola Bay，此时，rob的主语变为了Apalachicola Bay，不符合逻辑，其逻辑主语应该是increasing demands；and身后的不定式to make them decrease身前没有平行对象。另外，请注意，decrease in size和划线部分身后的less distinctive, and less in demand是平行的，根据功能平行原则，三者均是make的宾语的补足语，相当于三个句子的平行，即：
make them decrease in size, make them less distinctive, and make them less in demand.
B选项：本选项具有语法错误，it would rob和make them smaller之间缺少连词。
C选项：并列连词and使得“夺取牡蛎的味道（rob the oysters there of their flavor）”和“改变盐水成分（alter the saline content of Apalachicola Bay）”之间具有对等并列的关系。但在逻辑上，显然改变盐水成分是起因，夺取牡蛎味道是结果，因此两者不是并列而是因果关系。
D选项：Correct. 本选项在逻辑和语法上均是正确的。
E选项：rob和make是alter的两个并列的后果，两个并列是成分用and连接时，and身前不能有逗号。例如，一般我们说：
(1) James and I went to New York.
我们不说：
(2) **James, and I went to New York.
当投资100刀和每年能挣2刀并列时，应该写为：
I invested $100, holding 3 share, and could earn $2 per year.
此时不能写为：
I invested $100, and I held 3 share and could earn $2 per year.
E的逗号没有问题，问题在于decrease in size与后面的l形容词less distinctive， less in demand不能很好地组成平行结构
改变了Apalachicola Bay的含盐度，所以夺去了牡蛎的味道并且让它们的变得更小
故rob和decrease要作为伴随状语补充说明alter，与alter为因果关系，非并列关系
make them decrease in size, less distinctive, and less in demand.
这三个平行吗？
make sb do
make+adj.
两者分立开来都对，并在一起不对吧？？
——句意——
需求改变了含盐量，从而夺取了牡蛎的味道and是牡蛎变得更小了、更没特色了、更少被需求了
robbing the oysters there of their flavor and making them smaller
是伴随状语，主语是 increasing demands。 但是，难道不应该是alter the saline content 造成的么？
两个并列是成分用and连接时，and身前不能有逗号
rob the oysters there of their flavor和make them smaller ...的不是increasing demands，而是盐度变化，应该用独立主格来表示这种影响。
A which用法错误
B it指代作物
C rob的主语是increasing demands，错误
E and making them decrease in size前面不要逗号
平行ace b缺连词
但是e
rob和make是alter的两个并列的后果，两个并列是成分用and连接时，and身前不能有逗号。例如，一般我们说：
(1) James and I went to New York.
我们不说：
(2) **James, and I went to New York.
当投资100刀和每年能挣2刀并列时，应该写为：
I invested $100, holding 3 share, and could earn $2 per year.
此时不能写为：
I invested $100, and I held 3 share and could earn $2 per year.
Split#1：根据less distinctive, and less in demand.判断划线部分结尾部分应该是smaller（and平行），去掉选项A、C、E
Split#2：“alter the saline content”和“robbing”是因果关系，不是并列关系，选D
Split#1：根据less distinctive, and less in demand.判断划线部分结尾部分应该是smaller（and平行），去掉选项A、C、E
Split#2：“alter the saline content”和“robbing”是因果关系，不是并列关系，选D
make them decrease in size, make them less distinctive, and make them less in demand. 三者是平行的；
两个并列是成分用and连接时，and身前不能有逗号
A and to do 前面没有对应
B and +完整句，看到代词，找指代对象（但是没有东西可以rob flavor） 应该是demand改变了味道
C ，making 修饰rob这个动作，让making 变成下一层的关系，修饰
D ，robbing...and making 这个两个修饰 应该是并列的两个结果
E 后边的并列，逗号+making没比较加
E选项：rob和make是alter的两个并列的后果，两个并列是成分用and连接时，and身前不能有逗号。

smaller与less distinctive， less in demand平行
请注意，decrease in size和划线部分身后的less distinctive, and less in demand是平行的，根据功能平行原则，三者均是make的宾语的补足语，相当于三个句子的平行，即：make them decrease in size, make them less distinctive, and make them less in demand.
E选项：rob和make是alter的两个并列的后果，两个并列是成分用and连接时，and身前不能有逗号。
为什么A选项“to make”后面用“decrease in size”是平行的而C选项“making”后面的“decrease in size”就不平行了呢？
decrease in size和划线部分身后的less distinctive, and less in demand是平行的
rob和make是alter的两个并列的后果，两个并列是成分用and连接时，and身前不能有逗号
it指代不能指代一件事，盐分改变是夺去牡蛎味道的原因
