9、.CNot all people on holiday get pleasure from it.DAll trips are holidays.2.We all know that DNA has 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 an
10、d even an entire population. Molecular Genealogy (宗谱学) can use this unique identification provided by 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 t
11、o adoption, illegitimacy or lack of records. There are many communities and populations which have lost 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 o
12、f the Molecular Genealogy Research Group is to build a database containing over 100,000 DNA samples 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
13、world genetic make-up, it will eventually help in solving many issues regarding genealogies that could 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 datab
14、ase is being created, molecular genealogy can already verify possible or suspected relationships between 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 sampl
15、e of DNA from both and looking for common markers (in this case we can look primarily at the Y chromosome (染色体), explains George Green, a member of the BYU Molecular Genealogy research team.If two men suspected for some reason they have a common ancestor, ().Awe can decide according to their family
16、treeBwe can find the truth from their genetic markersCwe can compare the differences in their Y chromosomeDwe can look for written records to prove their relationship3.It was 3:12 a.m. when nine-year-old Glenn Kreamer awoke to the smell of burning. Except for the crackling of flames somewhere below
17、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 Todd. He ran downstairs through the smoke filled house to push and pull at K

19、mpossible 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 trained adult.On the bedroom telephone, luckily still wording, Glen

How old were you when you started to write, and what was your first bookW: I wrote my first finished
24、story when I was about 6. It was about a small animal, a rabbit I mean, and I’ve been writing ever since.M: Why did you choose to be an authorW: If someone asked me how to achieve happiness, step one would be finding out what you love doing most and step two would be finding someone to pay you

29、ernative (21) the burning of fossil fuels, no government has taken the least trouble to explain the dangers. Maybe they are (22) them. (23) the reason, the public must learn by experience, even though this (24) may be catastrophic.While it is true that nuclear reactors do not produce visible smoke,
30、it is certainly not (25) that they do not pollute. And the pollution they produce is much more insidious precisely because it is (26) .(27) inconvenient it may be for governments to publish all the facts, they have no moral excuse for not doing so, (28) they think they are acting in our best interes

What (30) all this waste It is (31) concrete tanks and stored on tank farms. It is (32) in disused salt mines. It is run into fractured rock. It is bu

The efforts of a fracture in the tank or a failure of the cooling system would be (35) .While every effort

But even then, governments would, presumably continue to belittle the hazards.It seems that (39) governments can get away with not telling the

Ex
35、amining a culture’s tools and technology can tell us about the group’s 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
36、hear for ourselves the actual 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 inst
37、ruments pictured in art. Through 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
38、 of most of the instruments in 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 duri
39、ng the past few centuries in 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 widesp
40、read, on the music culture as a whole.One more important part of music’s 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 developmen
41、ts. This is all part of the information 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.Which of the following best summariz
42、es the main idea of the passage ()AMusical instruments developed through the years will sooner or later be replaced by computers.BMusic cannot be passed on to future generations unless it is recorded.CFolk songs cannot be spread far unless they are printed on music sheets.DThe development of music c
43、ulture is highly dependent on its material aspect.7.Not all trips are holidays. For example, when people travel on business, they don’t have the time or the peace of mind to enjoy themselves. But when people take a vacation, do they always have funThe fact is some people who travel for pleasur
