In primitive societies ad
22、olescence is frequently a relatively short period 6f time, while in industrial societies with patterns of prolonged education coupled with laws against child labor, the period of adolescence is much longer and may include most of the second decade of ones life. Furthermore, the length of the adolesc
23、ent period and the definition of adulthood status may change in a given society as social and economic conditions change. Examples of this type of change are the disappearance of the frontier in the latter part of the nineteenth century in the United States, and more universally, the industrializati
24、on of an agricultural society.In modem society, ceremonies for adolescence have lost their formal recognition and symbolic significance and there no longer is agreement as to what constitutes initiation ceremonies. Social ones have been replaced by a sequence of steps that lead to increased recognit
25、ion and social status. For example, primary school graduation, high school graduation and college graduation constitute such a sequence, and while each step implies certain behavioral changes and social recognition, the significance of each depends on the socio-economic status and the educational am
26、bition of the individual. Ceremonies for adolescence have also been replaced by legal definitions of status roles, rights, privileges and responsibilities, It is during the nine years from the twelfth birthday to the twenty-first that the protective and restrictive aspects of child-hood and minor st
27、atus are removed and adult privileges and responsibilities are granted. The twelve-year-old is no longer considered a child and has to pay full fare for train, airplane, theater and movie tickets. Basically, the individual at this age loses childhood privileges without gaining significant adult righ
28、ts. At the age of sixteen the adolescent is granted certain adult rights which increase his social status by providing him with more freedom and choices. He now can obtain a drivers license; he can leave public schools; and he can work without the restrictions of child labor laws. At the age of eigh
29、teen the law provides adult responsibilities as well as rights; the young man can now be a soldier, but he also can marry without parental permission. At the age of twenty-one the individual obtains his full legal rights as an adult. He now can vote, he can buy liquor, he can enter into financial co
30、ntracts, and he is entitled to run for public office. No additional basic rights are acquired as a function of age alter majority status has been attained. None of these legal provisions determine at what point adulthood has been reached but they do point tO the prolonged period of adolescence.（分数：5
31、.00）(1).The period of adolescence is much longer in industrial societies because_.（分数：1.00）A.the definition of maturity has changedB.the industrialized society is more developedC.more education is provided and laws against child labor are madeD.ceremonies for adolescence have lost their formal recog
32、nition and symbolic significance(2).Former social ceremonies that used to mark adolescence have given place to_.（分数：1.00）A.graduations from schools and collegesB.social recognitionC.socio-economic statusD.certain behavioral changes(3).No one can expect to fully enjoy the adulthood privileges until h
33、e is _.（分数：1.00）A.eleven years oldB.sixteen years oldC.twenty-one years oldD.between twelve and twenty-one years old(4).Starting from 22,_.（分数：1.00）A.one will obtain more basic rightsB.the older one becomes, the more basic rights he will haveC.one wont get more basic rights than when he is 21D.one w
34、ill enjoy more rights granted by society(5).According to the passage, it is true that_.（分数：1.00）A.in the late 19th century in the United States the dividing line between adolescence and adulthood no longer existedB.no one can marry without the permission of his parents until the age of twenty-oneC.o
35、ne is considered to have reached adulthood when he has a drivers licenseD.one is not free from the restrictions of child labor laws until he can join the armyPassage 2Galaxies are the major building blocks Of the universe: A galaxy is giant family of many millions of stars, and it is held together b
36、y its own gravitational field. Most of the material universe is organized into galaxies of stars together with gas and dust.There are three main types of galaxy: spiral, elliptical, and irregular. The Milky Way is a spiral galaxy, a flattish disc of stars with two spiral arms emerging from its centr
37、al nucleus. About one-quarter of all galaxies have this shape. Spiral galaxies are well supplied with the interstellar gas in which new stars form: as the rotating spiral pattern sweeps around the galaxy it compresses gas and dust, triggering the formation of bright young stars. The elliptical galax
38、ies have a symmetrical elliptical or spheroidal shape with no obvious structure. Most of their member stars are very old and since ellipticals are devoid of interstellar gas, no new stars are forming in them. The biggest and brightest galaxies in the universe are ellipticals with masses of about 101
39、3 times that of the sun, these giants may frequently be sources of strong radio emission, in which case they are called radio galaxies. About two-thirds of all galaxies are elliptical. Irregular galaxies comprise about one-tenth of all galaxies and they come in many subclasses.Measurement in space i
40、s quite different from measurement on Earth. Some terrestrial distances can be expressed as intervals of time, the time to fly from one continent to another or the time it takes to drive to work, for example. By comparison with these familiar yardsticks, the distances to the galaxies are incomprehen
41、sibly large, but they too are made more manageable by using a time calibration, in this case the distance that light travels in one year. On such a scale the nearest giant spiral galaxy, the Andromeda galaxy, is two million light years away. The most distant luminous objects seen by telescopes are p
42、robably ten thousand million light years away. Their light was already halfway here before the Earth even formed. The light from the nearby Virgo galaxy set out when reptiles still dominated the animal world.（分数：5.00）(1).What does the second paragraph mainly discuss?（分数：1.00）A.The Milky Way.B.Major
43、categories of galaxies.C.How elliptical galaxies are formed.D.Differences between irregular and spiral galaxies.(2).According to the passage, new stars are formed in spiral galaxies due to_.（分数：1.00）A.an explosion of gasB.the compression of gas and dustC.the combining of old starsD.strong radio emis
44、sions(3).According to the passage, which of the following is NOT true of elliptical galaxies?（分数：1.00）A.They are the largest galaxies.B.They mostly contain old stars.C.They contain a high amount of interstellar gas.D.They have a spherical shape.(4).Which of the following characteristics of radio gal
45、axies is mentioned in the passage?（分数：1.00）A.They are a type of elliptical galaxy.B.They are usually too small to be seen with a telescope.C.They are closely related to irregular galaxies.D.They are not as bright as spiral galaxies.(5).Why does the author mention the Virgo galaxy and the Andromeda g
46、alaxy in the third paragraph?（分数：1.00）A.To describe the effect that distance has no visibility.B.To compare the ages of two relatively young galaxies.C.To emphasize the vast distances of the galaxies from Earth.D.To explain why certain galaxies cannot be seen by a telescope.BPassage 3/BMoviegoers ma
47、y think history is repeating itself this weekend. The summers most anticipated film, Pearl Harbor, which has opened recently, painstakingly recreates the Japanese attack that drew the United States into World War II. But that isnt the films only reminder of the past.Harbor invites comparison to Tita
48、nic, the biggest hit of ail time. Like Titanic, Harbor heaps romance and action around a major historical event. Like Titanic, Harbor attempts to create popular global entertainment from a deadly real life. Like Titanic, Harbor costs a pretty penny and hopes to get in even more at the box office. Both Titanic and Pearl Harbor unseal their tales of love and tragedy over more than three h
