In the US,people prefer waiting for a table to sitting with people they don't know．This means a hostess may not seat a small group until a small table is available,even if a large one is．If you are sitting at a table with people you don't know,it is impolite to light up a cigarette without first asking if it will disturb them. At American restaurants and coffee shops you are usually served tap water before you order．You may find the bread and butter is free,and if you order coffee,you may get a free refill. Most cities and towns have no roles about opening and closing times for stores or restaurants,though they usually do make rules for bars．Especially in large cities,stores may be open 24 hours a day． Servings in restaurants are often large,too large for many people．If you can't finish your meal but would like to enjoy the food later,ask your waitress or waiter for a"doggie bag"．It may have a picture of a dog on it,but everybody knows you are taking food for yourself. Supper and dinner are both words for the evening meal．Some people have"Sunday dinner"．This is an especially big noon meal. Tips are not usually added to the check．They are not included in the price of the meal,either．A tip of about 15%is expected and you should leave it on the table when you leave．In some restaurants,a check is brought on a plate and you put your money there．Then the waiter or waitress brings you your change.

A、a dinner in the evening
B、a big noon meal
C、a big meal on Sunday
D、a supper on Sunday
【正确答案】：B
【题目解析】：在原文中，关于“Sunday dinner”的描述明确指出：“This is an especially big noon meal.” 这意味着“Sunday dinner”是一个特别丰盛的午餐。根据给出的选项，我们可以逐项分析： A选项“a dinner in the evening”指的是晚上的晚餐，这与原文描述不符。 B选项“a big noon meal”与原文中的描述“This is an especially big noon meal”完全一致。 C选项“a big meal on Sunday”虽然也提到了“Sunday”和“big meal”，但原文特别指出这是一个丰盛的午餐，而非泛指任何时间的大餐。 D选项“a supper on Sunday”指的是周日的晚餐，同样与原文不符。 因此，正确答案是B，即“Sunday dinner”是一个丰盛的午餐。
