Shoppers in sporting goods stores, unlike in department stores, do very little impulse shopping, not buying a pair of skis and a boomerang when they come in for a basketball, but they leave with a basketball only

A.in department stores, do very little impulse shopping, not buying a pair of skis and a boomerang when they come in for a basketball, but they leave with a basketball only

B.in department stores, shop impulsively very little; someone who comes in for a basketball will leave with a basketball only and not also buy a pair of skis and a boomerang as well

C.those in department stores, do very little impulse shopping, do not buy a pair of skis and a boomerang when they come in for a basketball, but leave with only a basketball

D.those in department stores, do very little impulse shopping; someone who comes in for a basketball will leave with a basketball only and not buy a pair of skis and a boomerang as well
E.department stores, shop impulsively very little; someone will not buy a pair of skis and a boomerang when they come in for a basketball but will leave with only a basketball

正确答案选D，但是我错选了B。
B中also和as well错误比较明显，但是答案中说第一局shopper和department stores不平行，但是我的疑问是，刚在总结是看到一句说：比较从句的主语与主句主语相同，可以省略。
因此我以为这句说省略了相同的主语：Shoppers in sporting goods stores, unlike (shoppers)in department stores; 请问这样为什么错了呢？ 谢谢指点

like和unlike比较的主体就是名词,不能省.

like u, I do sth.
Unlike U, I do sth.好粗俗的例子..

U have to point out the noun after like /unlike

注意比较的对象。unlike前面是人（shopper），后面就必须是人，不能是store或者空着。。。

明白了，是as和than的比较可以省略名词吧？看来like是不能省的

UNLIKE 比较的就是两句的主语，同时童鞋你可以从意思分析，GMAT语法中逻辑意思是灰常重要滴
