Examining a cultu
20、res tools and technology can tell us about the groups history and way of life. Similarly, research into the material culture of music can help us to understand the music culture. The most vivid body of material culture in it, of course, is musical instruments. We cannot hear for ourselves the actual
21、 sound of any musical performance before the 1870s when the phonograph was invented, so we rely on instruments for important information about music cultures in the remote past and their development. Here we have two kinds of evidence: instruments well preserved and instruments pictured in art. Thro
22、ugh the study of instruments, as well as paintings, written documents, and so on, we can explore the movement of music from the Near East to China over a thousand years ago, or we can outline the spread of Near Eastern influence to Europe that resulted in the development of most of the instruments i
23、n the symphony orchestra.Sheet music or printed music, too, is material culture. Scholars once defined folk music cultures as those in which people learn and sing music by ear rather than from print, but research shows mutual influence among oral and written sources during the past few centuries in
24、Europe, Britain, and America. Printed versions limit variety because they tend to standardize any song, yet they stimulate people to create new and different songs. Besides, the ability to read music notation has a far-reaching effect on music and, when it becomes widespread, on the music culture as
25、 a whole.One more important part of musics material culture should be singled out: the influence of the electronic mediaradio, record player, tape recorder, television, and videocassette, with the future promising talking and singing computers and other developments. This is all part of the “informa
26、tion revolution“, a twentieth-century phenomenon as important as the industrial revolution was in the nineteenth. These electronic media are not just limited to modern nations; they have affected music cultures all over the globe.（分数：5.00）(1).Research into the material culture of a nation is of grea
27、t importance because_.（分数：1.00）A.it helps produce new cultural tools and technologyB.it can reflect the development of the nationC.it helps understand the nations past and presentD.it can demonstrate the nations civilization(2).It can be learned from this passage that_.（分数：1.00）A.the existence of th
28、e symphony was attributed to the spread of Near Eastern and Chinese musicB.Near Eastern music had an influence on the development of the instruments in the symphony OrchestraC.the development of the symphony shows the mutual influence of Eastern and Western musicD.the musical instruments in the symp
29、hony orchestra were developed on the basis of Near Eastern music(3).According to the author, music notation is important because_.（分数：1.00）A.it has a great effect on the music culture as more and more people are able to read itB.it tends to standardize folk songs when it is used by folk musiciansC.i
30、t is the printed version of standardized folk musicD.it encourages people to popularize printed versions of songs(4).It can be concluded from the passage that the introduction of electronic media into the world of music_.（分数：1.00）A.has brought about an information revolutionB.has speeded up the appe
31、arance of a new generation of computersC.has given rise to new forms of music cultureD.has led to the transformation of traditional musical instruments(5).Which of the following best summarizes the main idea of the passage?（分数：1.00）A.Musical instruments developed through the years will sooner or lat
32、er be replaced by computers.B.Music cannot be passed on to future generations unless it is recorded.C.Folk songs cannot be spread far unless they are printed on music sheets.D.The development of music culture is highly dependent on its material aspect.九、Text 2(总题数：1，分数：5.00)We all know that DNA has
33、the ability to identify individuals but, because it is inherited, there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended), tribal group and even an entire population. Molecular Genealogy (宗谱学) can use this unique identification provided b
34、y the genetic markers to link people together into family trees. Pedigrees (家谱) based on such genetic markers can mean a break-through for family trees where information is incomplete or missing due to adoption, illegitimacy or lack of records. There are many communities and populations which have l
35、ost precious records due to tragic events such as the fire in the Irish courts during Civil War in 1921 or American slaves for whom many records were never kept in the first place.The main objective of the Molecular Genealogy Research Group is to build a database containing over 100,000 DNA samples
36、from individuals all over the world. These individuals will have provided a pedigree chart of at least four generations and a small blood sample. Once the database has enough samples to represent the world genetic make-up, it will eventually help in solving many issues regarding genealogies that cou
37、ld not be done by relying only on traditional written records. Theoretically, any individual will someday be able to trace his or her family origins through this database.In the meantime, as the database is being created, molecular genealogy can already verify possible or suspected relationships bet
38、ween individuals. “For example, if two men sharing the same last name believe that they are related, but no written record proves this relationship, we can verify this possibility by collecting a sample of DNA from both and looking for common markers (in this case we can look primarily at the Y chro
39、mosome (染色体),“ explains George Green, a member of the BYU Molecular Genealogy research team.（分数：5.00）(1).People in a large area may possess the same DNA thread because_.（分数：1.00）A.DNA is characteristic of a regionB.they are beyond doubt of common ancestryC.DNA strand has the ability to identify indi
40、vidualsD.their unique identification can be provided via DNA(2).The possible research of family trees is based on the fact that_.（分数：1.00）A.genetics has achieved a breakthroughB.genetic information contained in DNA can be revealed nowC.each individual carries a unique record of who he is and how he
41、is related to othersD.we can use DNA to prove how distant an individual is to a family, a group or a population(3).The Molecular Genealogy Research Group is building a database for the purpose of_.（分数：1.00）A.offering assistance in working out genealogy-related problemsB.solving many issues without r
42、elying on traditional written recordsC.providing a pedigree chart of at least four generations in the worldD.confirming the assumption that all individuals are of the same origin(4).If two men suspected for some reason they have a common ancestor, _.（分数：1.00）A.we can decide according to their family
43、 treeB.we can find the truth from their genetic markersC.we can compare the differences in their Y chromosomeD.we can look for written records to prove their relationship(5).Which of the following CANNOT be inferred from the passage?（分数：1.00）A.We are a walking, living, breathing record of our ancest
44、ors.B.Many American slaves did not know who their ancestors were.C.An adopted child generally lacks enough information to prove his identity.D.Molecular genealogy can be used to prove a relationship between individuals.十、Text 3(总题数：1，分数：5.00)It was 3:12 a.m. when nine-year-old Glenn Kreamer awoke to
45、 the smell of burning. Except for the crackling of flames somewhere below there was not a sound in the two-storey house at Baldwin, Long Island.With his father away on night duty at a local factory, Glenn was worried about the safety of his mother, his sister Karen, 14 and his 12-year-old brother To
46、dd. He ran downstairs through the smoke filled house to push and pull at Karen and Todd until they sat up. Then he helped each one through the house to the safety of the garden. There, his sister and brother, taking short and quick breaths and coughing, collapsed on the lawn.The nine-year-old raced
47、back into the house and upstairs to his mothers room. He found it impossible to wake her up. Mrs. Kreamer, a victim of the smoke, was unconscious, and there was nobody to help Glenn carry her to the garden. But the boy remained calm and, as a fireman said later, “acted with all the self-control of a
48、 trained adult.“On the bedroom telephone, luckily still wording, Glenn called his father and, leaving Mr. Kreamer to telephone the fire brigade and ambulance service, got on with the task of saving his mother.First he filled a bucket with water from the bathroom and threw water over his mother and h
49、er bed. Then, with a wet cloth around his head he went back to the garden.He could hear the fire engine coming up, but how would the firemen find his mother in the smoke-filled house where flames had almost swallowed up the ground floor?Grasping firmly a ball of string from the garage, Glenn raced back into the house and dashed upstairs to his mothers room
