D 中 not buy .....A and B as well, 有否定词还用as well 是对的嘛？就是因为这个排除D的

C选项：do very little impules shopping和do not buy a pair of skis一个是概括，一个是细化，功能不同无法平行。另外，并列连词but不能连接三个并列成分，只能连接两个并列句。

c 同一主语有两个动词需要and连接并列，这里没有and也不是并列结构
d as well的用法，不能和also重复，但可以和and重复咯？？

C项不能平行，后面两个动作是do very little impules shoppingd的解释

do very little impules shopping和do not buy a pair of skis一个是概括，一个是细化，功能不同无法平行。另外，并列连词but不能连接三个并列成分，只能连接两个并列句。

A／B：there's also a grammatical issue, too -- like/unlike must be followed by a noun or pronoun. a prepositional phrase is not a noun or pronoun.

C
1) there's no such construction as "A, B, but C". i.e., "but" can't link three things in the way that "and" or "or" could.
2) it makes no sense to put all 3 of these things in parallel, because they don't belong in parallel; the last two are an explanation of the first one. i.e., the last two things are an explanation of the idea that these shoppers "do very little impulse shopping".

错选了C，没有理解句意。

错选了C选项 没有理解句子的意思，do not buy a pair of skis and a boomerang是 do very little impulse shopping的一个细化，二者不是不行关系
同时，C选项中用了A，B，but C的结构是错误的，but不能三者平列，只能连接两个并列句

D 分号前后两个句子，后面一个更加specific

there's also a grammatical issue, too -- like/unlike must be followed by a noun or pronoun. a prepositional phrase is not a noun or pronoun.

求问。。。为什么不可以理解为Shoppers in sporting goods stores, unlike （shoppers）in department stores, 比较的就是这两个地点呢？消费者在这两个地点有不一样的消费习惯

not...but平行

C
1) there's no such construction as "A, B, but C". i.e., "but" can't link three things in the way that "and" or "or" could.

2) it makes no sense to put all 3 of these things in parallel, because they don't belong in parallel; the last two are an explanation of the first one. i.e., the last two things are an explanation of the idea that these shoppers "do very little impulse shopping".

ABE比较对象不同，C平行错误。

副词also和as well均表示“也”，其中一个必然是赘余的。

选项E比较对象不等
unlike后面不能加介词短语，排除ab。同时B中的also和as well重复
选项C中的but连接了三个并列成分！
