Kinds of shops1.
49、Kinds of shopsShops are divided into multiple categories of stores which sell a selected set of goods orservices.Many shops are part of a chain: a number of similar shops with the same name selling thesame products in different locations. The shops may be owned by one company, or theremay be a franc
50、hising company that has franchising agreements with the shop owners (seealso restaurant chain).Some shops sell second-hand goods. Often the public can also sell goods to such shops. Inother cases, especially in the case of a nonprofit shop, the public donates goods to the shopto be sold (see also th

In give-away shops goods can be taken for free.For details on the various types of retail stores see:Army-navy stores; Bookstore; Convenience store; Department store; Dollar store;Electronic commerce, B2C; General store; Hardware store; Hobby store; Hypermarket;Mail order; Pet store; Ph

53、子里。如果你忘记这一条而把商品直接放进自己的袋子里而没有付款就离开，你可能会被指控为“入店行窃”，这可能会导致被警方控告犯有盗窃罪。 不幸的是，在英国的一些地方，“入店行窃”是一种相当普遍的盗窃方式，因此很多商店装有电子检测设备，并在起诉方面采取一种强硬政策。游客如果打算购买昂贵的家用物品，可以在公共图书馆查阅一下“Which”这份杂志。这份杂志对各个厂家产品的价钱和质量做出比较。在大超市购物，不用担心质量和价格有什么欺诈，在付款后，收款机会打印出一张详细的收据，内容包括：商场名称，当天的值班经理的名字、售货员姓名、购货种类、数量、价格、付款方式、找零以及商场地址、电话号码，如发现什么问题，可
54、以找商场解决。近年来，英国已经逐步制定了许多法律来保护消费者的权利。例如说，假如你能出示收据，店家必须调换有毛病的商品，所以一定要把收据和质量保证书保存好，尤其是购买大件物品的收据和质量保证书。3. 3.专挑打折期购物专挑打折期购物 美国人处处想省钱美国人处处想省钱美国虽然是世界上经济最发达的国家之一，但美国人的生活并不奢侈，有时甚至是一分钱掰成两半花。通常情况下，美国人手里的活钱并不多，每月除了还买房、买车的贷款外，煤气、水、电、电话、上网费、有线电视费等各种费用也是一大笔开销。经过东扣西扣， 最后手里剩下的零花钱就没多少了， 为此普通美国人花钱很少大手大脚。这一点从美国人的购物习惯也能看出
55、来。平常，美国的大商场里总是冷冷清清，但打折的时候可就不一样了。每年感恩节的第二天是美国最著名的商场打折日，许多商品都打5 折。到那天，等了很久的美国人会倾巢而出，所有商场都是人头攒动。有人为了抢到便宜货，甚至早晨5 点就起床出发学英语报社组织编写 2005-8Go for it J7A Unit7了。我的一位美国朋友格林女士想买个数码摄像机， 但她还一直没有采取行动。 她说：“我就等着今年的感恩节呢！”美国人不仅热中于在打折时购物，他们还酷爱优惠券。购物用的优惠券分两种，一种是在商品原价基础上便宜 10%20%，任何时候都可以用。另一种是可以直接代替美元使用的优惠券，上面标着 10 美元、2
56、0 美元不等，只要你购物超过一定数额，就可以直接用。不过这种优惠券一般只能在打折期间用，而且常常是只有“早起的鸟儿（Early bird）”才能使。除此之外，记者还了解到，美国人平时逛商场，大多数是只看不买，但每个人心里都在默记着自己已经看中的东西，然后静等打折期的到来。美国人不仅在购物时会省钱，他们在别的方面也有许多省钱的办法。在美国，修汽车的人工费非常贵，一小时就要几十美元。为了省钱，许多美国男士自学汽车的结构常识，掌握了不少简单的修车技术，如：补轮胎、换一些小零件等。 先生们学修车，太太们也不会闲着。由于去餐馆吃饭比较贵，一顿饭一个人至少要花上十几美元，所以绝大多数美国太太都有一手好厨艺
57、。电视上的厨艺节目、各种菜谱书籍和厨艺学习班也深受美国太太们喜爱。美国人自己制作的蛋糕一点不比商场里的逊色，却能省不少钱。在商场里，一个生日蛋糕要卖几十美元，而自己做的成本就低多了。II. Fun materialsII.
