Valentine’s Day is a popular festival of love and romance. There are      legends associated with the festival along with the belief that birds began to mate from this day. Historians trace (追踪)its      to an ancient Roman festival. It is said that in ancient Rome, people      a holiday on February 14th to honor Juno—the Queen of Roman Gods and Goddesses. On the following day, February 15th,the festival of Lupercalia was celebrated to honor the Roman God of Agriculture.
An interesting      was followed on the festival of Lupercalia to bring together young boys and girls who otherwise were strictly      . On the eve of the festival, names of young Roman girls were written on a slip of paper and placed into jars. Each young man      a girl's name from the jar and was paired with the girl during the festival. Sometimes the      lasted for a year until next year's celebration. Quite often,the couple would fall in love with each other and       marry. The custom lasted for a long time until people felt that it was un-Christian and that mates should be chosen by sight, not      .
The pairing of young boys and girls set the mood of the Valentine's Day Festival as we know today. But it was      due to the efforts and daring of a priest St Valentine that the festival got its       and clearer meaning. The story goes that Emperor Claudius II of Rome found it      to get soldiers and felt the reason why men did not join the      was that they did not wish to leave their wives and families. As a result, Claudius cancelled all marriages and engagements in Rome. St Valentine challenged Claudius's      order and secretly married couples. When his disobedience was      ,Valentine was put to death on February 14, around 270 AD. After his death Valentine was named a saint.

(2013·高考新课标全国卷Ⅱ,B)In 1947 a group of famous people from the art world headed by an Austrian conductor decided to hold an international festival of music,dance and theatre in Edinburgh.The idea was to reunite Europe after the Second World War.
It quickly attracted famous names such as Alec Guinness,Richard Burton,Dame Margot Fonteyn and Marlene Dietrich as well as the big symphony orchestras(交响乐团).It became a fixed event every August and now attracts 400,000 people yearly.
At the same time,the “Fringe” appeared as a challenge to the official festival.Eight theatre groups turned up uninvited in 1947,in the belief that everyone should have the right to perform,and they did so in a public house disused for years.
Soon,groups of students firstly from Edinburgh University,and later from the universities of Oxford and Cambridge,Durham and Birmingham were making the journey to the Scottish capital each summer to perform theatre by little­known writers of plays in small church halls to the people of Edinburgh.
Today the“Fringe”,once less recognized,has far outgrown the festival with around 1,500 performances of theatre,music and dance on every one of the 21 days it lasts.And yet as early as 1959,with only 19 theatre groups performing,some said it was getting too big.
A paid administrator was first employed only in 1971,and today there are eight administrators working all year round and the number rises to 150 during August itself.In 2004 there were 200 places housing 1,695 shows by over 600 different groups from 50 different countries.More than 1.25 million tickets were sold.
小题1:What was the purpose of Edinburgh Festival at the beginning?

Art museums are places where people can learn about various cultures. The increasingly popular "design museums" that are opening today, however, perform quite a different role. Unlike most art museums, the design museum shows objects that are easily found by the general public These museums sometimes even place things like fridges and washing machines in the center of the hall
Pele have argued that design museums are often made use of as advertisements for new industrial technology. But their role is not simply a matter of sales-it is the honoring of excellently invented products. The difference between the window of a department store and the showcase in a design museum is that the first tries to sell you something, while the second tells you the success of a sale.
One advantage of design museums is that they are places where people feel familiar with the exhihits. Unlike the average art museum visitors, design museum visitors seldom feel frightened or puzzled. This is partly because design museums clearly show how and why mass-produced products work and look as they do, and how design has improved the quality of our lives. Art museum exhibits, on the other hand, would most probably fill visitors with a feeling that there is something between their understanding.
In recent years, several new design museums have opened their door. Each of these museums has tried to satisfy the public’s growing interest in the field with new ideas. London's Design Museum, for example, shows a collection of mass-produced objects from Zippo lighters to electric typewriters to a group of Italian fish-tins. The choices open to design museums seem far less strict than those to art museums, and visitors may also sense the humorous part of our society while walking around such exhibits as interesting and unusually attractive toys collected in our everyday life.
小题1:Showcases in design museums are different from store windows because they_.
A.show more technologically advanced products
B.help increase the sales of products
C.show why the products have sold well
D.attract more people than store windows do
小题2:The author believes that most design museum visitors_.
A.do not admire mass-produced products
B.are puzzled with technological exhibits
C.dislike exhibits in art museums
D.know the exhibits very well
小题3:The choices open to design museums_
A. are not as strict as those to art museums
B, are not aimed to interest the public
C. may fail to bring some pleasure to visitors
D. often contain precious exhibits
小题4:The best title for this passage is“_”
A.The Forms of Design Museums
B.The Exhibits of Design Museums
C.The Nature of Design Museums
D.The Choices Open to Design Museums

Americans use many expressions with the word dog. People in the United States love their dogs and treat them well. They take their dogs for walks, let them play outside and give them good food and medical care. However, dogs without owners to care for them lead a different kind of life. The expression, to lead a dog's life, describes a person who has an unhappy life. 
Some people say we live in a dog-eat-dog world. That means many people are competing for the same things, like good jobs. They say that to be successful, a person has to work like a dog. This means they have to work very, very hard. Such hard work can make people dog-tired. And, the situation would be even worse if they became sick as a dog. 
Still, people say every dog has its day. This means that every person enjoys a successful period during his or her life. To be successful, people often have to learn new skills. Yet, some people say that you can never teach an old dog new tricks. They believe that older people do not like to learn new things and will not change the way they do things. 
Some people are compared to dogs in bad ways. People who are unkind or uncaring can be described as meaner than a junkyard dog. Junkyard dogs live in places where people throw away things they do not want. But mean dogs are often used to guard this property. They bark or attack people who try to enter the property. However, sometimes a person who appears to be mean and threatening is really not so bad. We say his bark is worse than his bite. 
Dog expressions also are used to describe the weather. The dog days of summer are the hottest days of the year. A rainstorm may cool the weather. But we do not want it to rain too hard. We do not want it to rain cats and dogs.
小题1:A person who lives an unhappy life can be described as “_______”.

The most important holiday in spring, especially for Christians (基督徒), is Easter. This Christian holiday is not on the same date every year, but it‘s always on a Sunday. It can be any Sunday between March 22 and April 25. Many people celebrate Easter by buying new clothes. Children celebrate by hunting for colored eggs that their parents have hidden around the house. People also give Easter baskets filled with candy and other goodies to one another to celebrate the day.

Getting married can be one of the happiest moments in a person’s life. Throughout the world, weddings are very important events. Let’s look at some interesting wedding customs from different countries.
For African Americans, it is tradition for the married couple to jump over a broom covered with flowers. This represents the beginning of family life. It is interesting to note that African slaves who were brought to the USA started this tradition. African American couples were not allowed to have a legal marriage, so instead they had a ceremony where the bride and groom jumped over a broom “into marriage”.
Making jokes about the bride and groom is a wedding tradition in both France and Germany. In France, this includes making loud noises with pots; in Germany, wedding guests break dishes. Weddings in Germany often last for three days. On Thursday, there is a simple ceremony at a government office noting the official marriage of the couple. Then the couple will have a dinner with family and close friends. On Friday, there is a party. This is when guests break dishes to represent the start of a new life. Then on Sunday, there is a ceremony in a church.
In Greece and Italy, people eat special kinds of sweets at the wedding. Both Greece and Italy also have their own special wedding dances, which all of the guests enjoy.
In Russia, couples tie a doll to their wedding car if they want to have a daughter, or a toy bear if they want to have a son.
In England, it is tradition for the little girls to throw flowers on the ground on the way to the wedding ceremony. The bride and groom walk on these flowers. This represents the hope that the couples will follow the path that leads to a happy life.

American and British use different greetings. In the USA the commonest greeting is “Hi”. In Britain it is “Hello!” or “How are you?”. “Hi!” is creeping(不知不觉的)into British, too. When they are introduced to someone, the Americans say, “Glad to know you.” The British say, “How do you do?” or “Pleased to meet you.” When Americans say “Good­bye”, they nearly always add, “Have a good day,” or “Have a good trip,” etc. to friends and strangers alike. Britons are already beginning to use “Have a good day”。
The British usually use “got”in the sense of “have”. The Americans hardly ever do.
Am.E: Do you have a car, room,etc.?Yes, I do.
Br.E: Have you got a car, room, etc.? Yes, I have.
Finally, there are a number of differences between American and British English in the spelling of words, e.g.check(US)/cheque(UK); center(US)/centre(UK). Many American words ending in “or”, e.g. honor, vigor, labor are spelt in British English with an “our”, e.g. honour, vigour, labour. Many verbs in American English with “ize”or “izing” forms, e.g. organize, realizing are spelt in Br.E “ise”or “ising”,e.g.organise,realising.In American English, “practice”is used both for the verb and noun.In Br.E, the verb is spelt “practise”, and the noun “practice”. In the main, American English  avoids the doubling up of consonants(辅音字母)in nouns and verbs while British English does not.In American English, for example, one writes “travel, traveled, traveling, traveler,” while in British English, one writes  “travel, travelled, travelling, traveller”.
It was once predicted that British and American English would became separate languages finally. But the opposite has happened. The links(连接)between the two countries are so strong that linguistically(语言上的), and probably culturally(文化上的)too, they are closer together than ever.
小题1:The Americans hardly say________.
A.Good­bye.Have a good day!B.Glad to know you!
C.Hi!D.Have you got a car?
小题2:A British writes________.
A.cheque;centerB.honor;organise
C.traveled;practice D.labour;traveller
小题3:What does the fifth paragraph talk about?
A.There are lots of differences in spelling between Am.E.and Br.E.
B.Why do the Americans and the British use different spellings?
C.There are few differences in spelling between Am.E.and Br.E.
D.The different usages of words in Am.E and Br.E
小题4:Which of the following is TRUE?
A.The two languages will become separate languages.
B.American English will be used more and more.
C.The two languages will be closer and closer.

Janice is an American engineer working in Nanjing. She and her husband George, who is teaching English at a university, have been eager to get to know Chinese people better, so they were pleased when Liu, Janice’s young co-worker, invited them to her home for dinner.
When they arrived, Liu introduced them to her husband Yang and asked them to sit down at a table containing eight plates of various cold dishes. Half an hour later she came back and sat down and the three began to eat. Yang came in from time to time, putting hot dishes on the table.
