11、t to deny that the Black gospel music of the early twentieth century differed in important ways from the slave spirituals. Whereas spirituals were created and dis- seminated in folk fashion, gospel music was composed, published, copyrighted, and sold by professionals. Nevertheless, improvisation rem
12、ained central to gospel music. One has only to listen to the recorded repertoire of gospel songs to realize that Black gospel singers rarely sang a song precisely the same way twice and never according to its exact musical notation. They performed what jazz musi- cians call “head arrangements“ proce
13、eding from their own feelings and from the way “the spirit“ moved them at the time. This improvisatory element was reflected in the man- ner in which gospel music was published. Black gospe composers scored the music intended for White singing groups fully, indicating the various vocal parts and the
14、 accompaniment, but the music produced for Black singers included only a vocal line and piano accompaniment（分数：4）(1).Which of the following best describes “head arrange- ment“ as the term is used in line 11?（分数：1）A.A published version of a gospel song produced for use by Black singersB.A gospel song
15、 based on a slave spiritualC.A musical score shared by a gospel singer and a jazz musicianD.An informally written composition intended for use by a gospel singerE.An improvised performance inspired by the singers emotions(2).The author mentions “folk fashion“ (line 4) most likely in order to（分数：1）A.
16、counter an assertion about the role of improvi- sation in music created by Black peopleB.compare early gospel music with gospel music written later in the twentieth centuryC.make a distinction between gospel music and slave spiritualsD.introduce a discussion about the dissemination of slave spiritua
17、lsE.describe a similarity between gospel music and slave spirituals(3).The passage suggests which of the following about Black gospel music and slave spirituals?（分数：1）A.Both became widely known in the early twentieth centuryB.Both had an important improvisatory element.C.Both were frequently perform
18、ed by jazz musicians.D.Both were published with only a vocal line and piano accompaniment.E.Both were disseminated chiefly by Black singing groups.(4).Of the following sentences, which is most likely to have immediately preceded the passage?（分数：1）A.Few composers of gospel music drew on traditions su
19、ch as the spiritual in creating their songs.B.Spirituals and Black gospel music were derived from the same musical traditionC.The creation and singing of spirituals, practiced by Black Americans before the Civil War, continued after the warD.Spirituals and gospel music can be clearly distinguished f
20、rom one anotherE.Improvisation was one of the primary characteristics of the gospel music created by Black musicians.There are seven questions belowAbout a century ago, the Swedish physical scientist Arrhenius proposed a law of classical chemistry that relates chemical reaction rate to temperature.
21、According to the Arrhenius equation, chemical reaction are increasingly unlikely to occur as temperatures approach absolute zero,and at absolute zero (zero degrees Kelvin, or minus 273 degrees Celsius) reactions stop. However, recent experi- mental evidence reveals that although the Arrhenius equati
22、on is generally accurate in describing the kind of chemical reaction that occurs at relatively high temperatures, at tem- peratures closer to zero a quantum- mechanical effect known as tunneling comes into play; this effect accounts for chemical reactions that are forbidden by the principles of clas
23、si- cal chemistry. Specifically, entire molecules can “tunnel“ )through the barriers of repulsive forces from other mole- cules and chemically react even though these molecules do not have sufficient energy, according to classical chemistry, to overcome the repulsive barrier. The rate of any chemica
24、l reaction, regardless of the tem-perature at which it takes place, usually depends on a very important characteristic known as its activation energy. Any molecule can be imagined to reside at the bottom of a so- called potential well of energy. A chemical reaction corre- sponds to the transition of
25、 a molecule from the bottom of one potential well to the bottom of another. In classical chemistry, such a transition can be accomplished only by going over the potential barrier between the wells, the height of which remains constant and is called the activation energy of the reaction. In tunneling
26、, the reacting mole-cules tunnel from the bottom of one to the bottom of another well without having to rise over the barrier between the two wells. Recently researchers have developed the concept of tunneling temperature: the temperature below which tunneling transitions greatly outnumber Arrhenius
27、 transi ions, and classical mechanics gives way to its quantum counterpart. This tunneling phenomenon at very low temperatures suggested my hypothesis about a cold prehistory of life: the formation of rather complex organic molecules in the deep cold of outer space, where temperatures usually reach
28、only a few degrees Kelvin. Cosmic rays (high-energy protons and other particles) might trigger the synthesis of simple molecules, such as interstellar formaldehyde, in dark clouds of interstellar dust. Afterward complex organic molecules would be formed, slowly but surely, by means of tunneling. Aft
29、er I offered my hypothesis, Hoyle and Wickramasinghe argued that molecules of interstellar form- aldehyde have indeed evolved into stable polysaccharides such as cellulose and starch. Their conclusions, although strongly disputed, have generated excitement among investigators such as myself who are
30、proposing that the galactic clouds are the places where the prebiological evolution of compounds necessary to life occurred.（分数：7）(1).The author of the passage is primarily concerned with（分数：1）A.describing how the principles of classical chemistry were developedB.initiating a debate about the kinds
31、of chemical reactions required for the development of lifeC.explaining how current research in chemistry may be related to broader biological concernsD.reconciling opposing theories about chemical reactionsE.clarifying inherent ambiguities in the laws of clas- sical chemistry(2).According to the pas
