GWD-3-Q34 【关于D选项的讨论】

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

答案选D。ABE很好排除。但是D选项我认为还有一些问题。

1）and 和as well是不是重复使用？

2）C选项的do..., do not, but leave算不算平行？如果不算，是不是因为do是助动词，而leave是实义动词？

3）如果不是上述原因，那么把but换成and对不对？

希望NN解惑，先感谢一下
