参考答案及解析：

1. A) 此空和shoplifting, long lines为并列结构，构成介词of的宾语，因此选项B和C可以排除；而选项D problems与of结构所修饰的problems有冲突，故只有选项A为正确答案。
2. B) 此空涉及固定搭配。come up with意为“提出，跟上”。come along with意为“随同”，意义不符。
3. A) 通过分析此空所在句可知，现在光顾一家OK超市的顾客推着一辆拴有一个塑料卡片的手推车从货架上购物，因此空白处需要一个介词引导一个复杂宾语结构来修饰名词a cart，四个选项中只有with有此功能。
4. A) 根据短文，这类超市发放的带有磁码的塑料卡片由每位顾客在购物时携带，出超市时在出口处被收集回来，因此此空应选A collected “收集，回收”，其它各选项意义不符。
5. D) 根据句义（顾客不管想买哪种商品他都需要把卡片插到这种商品旁边的插口里，然后按一下按钮。）和结构（此空需要一个联接词语作介词beside的宾语）可知选项D为正确答案。
6. C) 电脑知道所有商品的价格，故C为正确答案。
7. B) 此题涉及动词意义搭配问题，feed意为“送入，插入”。
8. C) 经过分析可推断句义为“一旦你碰了一件商品，不管你把塑料片藏到哪儿，即便是吃到肚子里，电脑也会记录下来。”，从而断定答案为C。
9. B) 此句带有比较状语从句，故空白处词应与句子主语相对应。friend和neighbour不合逻辑，只有colleague为正确答案。
10. A) 此句是一例子，故答案为A。
11. B) “be about to”意为“即将发生…”。
12. A) 根据句义应为A warns。
13. A) “change one's mind at” 为固定搭配。
14. D) 根据上文可知如果你碰了某种商品，电脑就会记录下来，从而推测此句句义为“一旦你碰了某个商品，就不能放回去了。”因此本题正确答案为D。
15. C) 根据上下文可断定为C。
