　　 Imagine that the genome(基因组) is a book.　 The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels.　 There are one billion words in the book, which makes it longer than 5,000 volumes the size of this book, or as long as 800 Bibles.　 If I read the genome out to you at the rate of one word per second for eight hours a day, it would take me a century.　 If I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube.　 This is an enormous document, a huge volume, a cook book of great length, and it all fits inside the extremely small nucleus of a tiny cell that fits easily upon the head of a pin.

　　 The idea of the genome as a book is not, strictly speaking, even a metaphor(比喻).　 It is true to a great extent.　 A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of signs into a large dictionary of meanings through the order of their groupings.　 So is a genome.　 The only complication is that all English books read from left to right, while some parts of the genome read from left to right, and some from right to left, though never both at the same time.

　　 While English books are written in words of different lengths using twenty-six letters, genomes are written entirely in three-letter words, using only four letters.　 And instead of being written on flat pages, they are written on long chains of DNA molecules(分子).　 The genome is a very clever book, because in the right conditions it can both photocopy itself and read itself.

　　 C. They need those well-known ancient objects to attract people from all over the world.

　　　　　　　　　　　　　　 (C)

　　　 In 1993, the Metropolitan Museum of Art reluctantly handed over 363 pieces of gold, silver, precious stones, painting, and sculptures back to Turkey after a court case.　 Following increasing calls for the return of artistic objects that were removed decades or centuries ago, some of the world’s leading museums have signed a declaration that they will not hand back the ancient artifacts to their countries of origin.　 They say people all over the world have only been able to fully appreciate ancient civilizations because these museums have provided access to these artistic objects.　 The ancient civilizations would not be so deeply admired today if these ancient artifacts were not so widely available to an international public in major museums throughout Europe and America.　 For example, Egyptian culture would not have become so well-known if the museums had not put Egyptian mummies on show.

　　　 The British Museum has not signed the declaration, but says it fully supports it.　 Over the recent years, it has faced growing pressure to hand back the Elgin Marbles, sculptures taken from the Parthenon in Athens, Greece, in the 19th century.　 But the British Museum has said that the Museum is the best possible place for them.　 “They must remain here if the museum is to continue to achieve its aim, which is to show the world to the world,” said the director of the museum.

　　　　　　　　　　　　　　 (B)

　　　 That cold January night, I was growing sick of my life in San Francisco.　 There I was walking home at one in the morning after a tiring practice at the theatre.　 With opening night only a week ago, I was still learning my lines.　 I was having trouble dealing with my part-time job at the bank and my acting at night at the same time.　 As I walked, I thought seriously about giving up both acting and San Francisco.　 City life had become too much for me.

　　　 As I walked down empty streets under tall buildings, I felt very small and cold.　 I began running, both to keep warm and to keep away from any possible robbers.　 Very few people were still out except a few sad-looking homeless people under blankets.

　　　 About a block from my apartment, I heard a sound behind me.　 I turned quickly, half expecting to see someone with a knife or a gun.　 The street was empty.　 All I saw was a shining streetlight.　 Still, the noise had made me nervous, so I started to run faster.　 Not until I reached my apartment building and unlocked the door did I realize what the noise had been.　 It had been my wallet falling to the sidewalk.

　　　 Suddenly I wasn’t cold or tired anymore.　 I ran out of the door and back to where I’d heard the noise.　 Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found.

　　　 Just as I was about to give up the search, I heard the garbage truck pull up to the sidewalk next to me.　 When a voice called from the inside, “Alisa Camacho?”　 I thought I was dreaming.　 How could this man know my name?　 The door opened, and out jumped a small red-haired man with an amused look in his eye.　 “Is this what you’re looking for?” he asked, holding up a small square shape.

　　　 It was nearly 3 A.M. by the time I got into bed.　 I wouldn’t get much sleep that night, but I had gotten my wallet back.　 I also had gotten back some enjoyment of city life.　 I realized that the city couldn’t be a bad place as long as people were willing to help each other.
