答案

参考答案:A, B, C

解析:湿式和干式自动喷水灭火系统联动控制设计。报警阀压力开关的动作信号作为系统启动的联动触发信号,直接控制启动喷淋消防泵,系统的联动控制不受消防联动控制器处于自动或手动控制状态的影响。《消防安全技术实务》第293页。

根据短文内容,从短文后的选项中选出能填入空白处的最佳答案。选项中有两项为多余选项。

Is the customer always right?    小题1:   Shopping is very much a part of a country’s culture, and attitudes to shopping and consumers vary from country to country just as much as climate or taste in food.

Recent economic hardship has given the consumers increased power in Europe because shopkeepers fight to win their share of reduced disposable(可支配的)income. This has meant falling prices, plenty of special offers and a re-examination of what customer service really means.

   小题2:  In restaurants in the south of the USA, for example, waiters compliment(恭维)you on your clothes, ask about your day, compliment you on your wisdom of your order and then return every ten minutes to refill your glass and make sure that everything is to your satisfaction.

Anyone who has waited 30 minutes to be served in a restaurant may possible dream of such customer service.     小题3:  In fact, different nationalities expect different types of service. As a friend of mine once told me “By the end of evening I had spent as much time talking to the waiter as to my wife.”

A Chinese-American friend loves telling people about how her Chinese mother shops for clothes. First of all she waits until they are on sale.     小题4:  And later she finds some small fault with the product and demands a further reduction. She never buys anything at the regular price. Could you imagine trying such ways in department stores in other countries?0

Attitudes to service are, of course, affected by employer’s attitudes to their workers. As American waiters heavily depend on tips, they have to provide more service. But is this fair?     小题5:    It might not be a case of “Is the customer always right?” but a case of “How much service is it fair to expect?”

A.People often point to America as an example of good customer service.

B.It is a question of expectations.

C.Do we think it is fair to ask shop assistants to work late evenings or on Sundays?

D.Then she asks for a discount until she gets an even better price.E. The answer, it seems, depends on which country you are in.

F. The way we shop shows the way we get along with other people.

G. However, do Europeans really want US style service?
