In the United States you will find yourself being urged from every page of every newspaper and every television station to buy all kinds of goods.

Not only is there a wide range of prices for goods in America, there is also a wide range in the quality of goods offered for sale. Unlike some countries,

Americans generally pay the price of a product without question, instead of trying to get a lower price by bargaining. However, there are many “sales” in the United States, during which time stores will lower their normal prices. This may all be very confusing to visitors. How are you going to know how to “get your money’s worth” when you shop? Perhaps the best advice is: Don’t hurry. Visit various stores and determine the quality of goods. Read the advertisements so that you can compare prices.

There is a great variety of shops in the United States, ranging from very large stores called “department stores” to very small shops. There are “discount houses” offering goods at low prices, and “dime stores” specializing in a wide range of inexpensive items.

Most department stores in large cities carry better quality products at higher prices. However, they offer the shoppers great convenience since they contain such a wide variety of products.

If convenience isn’t as important to you as price, you may want to shop in discount houses. These stores have nearly as great a variety of goods as department stores, but offer lower prices. They can do so for several reasons. They don’t offer the same services to buyers that department stores do; there may be fewer sales people; and the store probably doesn’t deliver purchases.

Another popular shop is the “dime store”. No longer selling many things for five or ten cents, these stores got their name in the last century when it was decided that a small profit on a great quantity of goods would be better than a large profit on fewer sales. Dime stores specialize in a wide variety of inexpensive items and today, prices range from a quarter or 50 cents up to several dollars.

单项选择题

案例二:一般资料:黄某,女性,20岁,护校学生。案例介绍:上解剖课时,老师要求同学们数人体模型有多少根骨头并记住,黄某和同学数的数总是不一样。从那以后,她看见骨头就爱数,包括吃完的鱼骨头、鸡骨头和猪排骨等,每次多达十几遍,数不清或数不对就重数。黄某明知没有必要,觉得无聊和厌烦,但始终控制不了自己,非常痛苦。老师同学发现后劝她不要这么做,但都无效。三个月前和同学一起逛街,她看见柜台旁的人体模型,突然用手去摸,嘴里念叨:“我要数数,有多少根骨头。”一周前黄某突然明显话多,滔滔不绝,同学反映她说话不连续,晚上也不睡觉,好像很精神。白天四处游荡,说看见学校宣传栏里有数骨头比赛的通知,她一定要好好练习,争取夺第一。国庆节学校周围摆放了许多鲜花,道路两旁也挂满了彩旗,黄某说:“等着吧,他们马上要给我评奖呢。”心理咨询师观察了解到的情况:黄某由父母强行带来,说黄某从小自我要求严格,非常固执,家里的东西都要按她的意见摆放,位置不对或不在原来的地方,她一定要改过来,觉得乱了就要立即整理。目前老师建议其休学看病,而黄某不承认有问题,在家长的强制下来到心理咨询室。
