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.

Passage Four
Thediscovery of a dwarfed（矮个子）"humanbeing"who lived in Flores,Indonesia,up to 18,000 years ago is changingthe way we think about the human family.This"Flores Human"was threefoot tall and her brain was smaller than that of the average chimp（黑猩猩）,yet she and her relatives apparently lived fully human lives.They seem to have made tools,worked together to find food and cook it,andperhaps even burried their dead with ceremony.
It was a major surprise to find tools associated with the newhuman family member.The tools are like those formerly seen only with Europeanfossils（化石）from our own species;Homo sapiens（智人）;and the oldest of them were made 9,400 years ago.Homo sapiens isthought to have arrived in the island about 4,000 years ago,much too late tobe responsible for the tools.If this tiny human made the tools,then theinside structure（结构）of its brain must have been morelike our own than a chimp′s,despite being just a third the size of ours.
This"new human"was suspected to be a dwarfed branch ofHomo erectus（直立人,）.When creatures are separated in regionswith rare resources but few enemies,being big is a disadvantage,and evolutiontends to shrink them,a process known as island dwarfing.Could naturalselection make a human smaller while keeping--even improving--mental ability?Quite possibly,believes Christopher Wills of the University of California.
Has the"Flores Human"even shown the ability oflanguage?"I find it difficult to imagine that people could make tools,use fire,and kill large animals without fairly advanced communication,"Wills says.Did"Flores Human"possess the basic components of humanculture--such as the burying of the dead with ceremony?Emiliano Bruner of theItalian Institute points out that Indonesia′s hot,wet environment is bad forfossilization.It is reasonable to assume,he says,that the 18,000-year-oldbones of the most complete Flores woman were well-preserved because she wasburied with special care.

According to the passage,it isbelieved that"Flores Human"__

A.was dwarfed by its enemies
B.could use language
C.left a lot of fossils in the hot andwet environment
D.reached Flores 40,000 years ago
