The earliest printed book we known today appeared in Chinain the year 868, and metal type was in use in Korea at the beginning of thefifteen century, (12)but it was in Germany around the year 1450 that aprinting press using movable metal type was invented. Capitalism turnedprinting from an invention into an industry. Right from the start, bookprinting and publishing were organized on capitalist lines.(13) The biggestsixteenth-century printer, Planting of Antwerp, had 24 printing presses andemployed more than a hundred workers. Only a small fraction of thepopulation was literate, but the production of books grow at an extraordinaryspeed. By 1500 some 20 million volumes had already been printed. (14)Theimmediate effect of printing was to increase the circulation of works that werealready popular in a handwritten form, while less popular works went out ofcirculation. Publishers were interested only in books that would sell fairlyquickly in sufficient numbers to cover the costs of production and make aprofit. Thus, while printing enormously increased access to books by makingcheap, high-volume production possible, it also reduces choice.

(15)The great culture impactof printing was that it facilitated the growth of national languages. Mostearly books were printed in Latin, but the market for Latin was limited, and inits pursuit of larger markets the book trade soon produced translations intothe national languages emerging at the time. Printing indeed played a key role instandardizing and stabilizing these languages by fixing them in print, and producingdictionaries and grammar books.

You dream about being a moviestar. You’ll live in a big house in Hollywood, go to the Oscars every year—andwin! You’ll be rich and famous. Wait a minute, you also hate having your photostaken, and you’re very shy, so how could you ever become a movie star?

 Choosing the right career can be hard.(16)Many people graduate from school or college not knowing what to do withtheir lives, and get a job without really thinking about it. For some,things work out fine, but others often find themselves stuck in a job theyhate. Your working life lasts in average of forty years, so it’s important tofind a job you like and feel enthusiastic about. Luckily, there are many waysyou can get help to do this.

 The Australian website, www. careersonline. com, compares choosing a career with going to the movies. Before yousee a movie, you find out what films are showing. (17)The site suggests youshould do the same with your career—find out what jobs are available and what your options are. Next,decide which movie you like best. If you’re not a romantic person, you won’twant to see a love story. In other words, with your career, you should decidewhich job will suit your personality. Finally, decide how to get movie tickets,and find out where the theater is before you go. With your career, you need tofind information about where you can work, and how to get a job in thatprofession.

     (18)So how do you start? Begin by asking yourself some questions,Some jobs require you to have certain life experiences: Have you travelledoverseas? Do you have any extra certificates besides your degree, such as afirst aid license for example? Your physical state and build can alsoaffect which jobs you can do. A person, for example, who is allergic to cats,would probably never become an animal doctor. Flight attendants, firefightersand police officers have to be over a certain height, and be physically fit.Your personality matters, too. Are you outgoing or shy? If you like workingalone, a job that requires lots of teamwork might not suit you.

  Choosing a career can take timeand a lot of thought. However, when you know you can look forward to working inyour dream job, you will be glad you thought it through.

(21)Kwanzaa is a Kiswahili wordmeaning “the first fruits of the harvest.”

The East African language of Kiswahili waschosen as an official language of Kwanzaa because it is a non-tribal languagespoken by a large portion of the African population. Also, its pronunciation iseasy. Kwanzaa is based on seven principles which are unity, self-determination,collective work and responsibility, cooperative economics, purpose, creativityand faith. One principal is highlighted each day of the holiday.

In preparation for the celebration, a straw mat is placedon the table, along with a candle holder with seven candles, one black, threered, and three green. The black candle represents the African-American people,the red is for their struggles, and the green represents their hopes for thefuture.

    Other itemsplaced on the table are a variety of fruit, ears of comes, gifts and a communalunity cup for pouring and sharing drinks. Each day of Kwanzaa, usually beforethe evening meal，familyand friends gather around the table and someone lights the candle, beginningwith the black. After that, candles are lit alternatively from left to right.(22) While the candle is being lit, a principal is recited;then eachperson present takes a turn to speak about the importance that the principlehas to himself or herself.

Next, the ceremony focuses onremembering those who have died. A selected person pours water or juice fromthe unity cup into a bowl. That person then drinks from the cup and raises ithigh saying “Harambee”which means “Let’s all pull together.” All repeat “Harambee”seven times and each person drinks from the cup.

【听力原文】

The Mediterranean diet isbased upon the eating patterns of traditional cultures in the Mediterranean region.（23）Severalnoted nutritionists and research projects have concluded that this diet is oneof the most healthful in the world in terms of preventing such illnesses asheart disease and cancer, and increasing life expectancy.

The countries that have inspired theMediterranean diet all surround the Mediterranean Sea. These cultures haveeating habits that developed over thousands of years. In Europe, parts ofItaly, Greece, Portugal, Spain, and southern France adhere to principles of theMediterranean diet, as do Morocco and Tunisia in North Africa. Parts of theBalkan region and Turkey follow the diet, as well as Middle Eastern countrieslike Lebanon and Syria. The Mediterranean region is warm and sunny, andproduces large supplies of fresh fruits and vegetables almost year round thatpeople eat many times a day. Wine, bread, olive oil and nuts are other staplesof the region, and the Mediterranean Sea has historically yielded abundantquantities of fish.

Internationalinterest in the therapeutic qualities of the Mediterranean diet began back inthe late 1950s, when medical researchers started to link the occurrence ofheart disease with diet. Dr. Ancel Keys performed an epidemiological analysisof diets around the world. (24)Entitled the Seven Countries Study, it isconsidered one of the greatest studies of its kind ever performed. Init, Keys gathered data on heart disease and its potential causes from nearly13,000 men in Greece, Italy, Croatia, Serbia, Japan, Finland, the Netherlands,and the United States. The study was conducted over a period of decades. Itconcluded that the Mediterranean people in the study enjoyed some significanthealth advantages. (25)The Mediterranean groups had lower mortality rates inall age brackets and from all causes, particularly from heart disease. Thestudy also showed that the Mediterranean diet is as high or higher in fat thanother diets, obtaining up to 40% of all its calories from fat. It has, however,different patterns of fat intake. Mediterranean cooking uses smaller amounts ofsaturated fat and higher amounts of unsaturated fat, mostly in the form ofolive oil. Saturated fats are fats that are found principally in meat and dairyproducts, although some nuts and vegetable oils also contain them. Saturatedfats are used by the body to make cholesterol,and high levels of cholesterolhave since been directly related to heart disease.
