  space between the galaxies in our universe was a near-

  perfect vacuum. This orthodox view of the universe is

   now being challenged by astronomers who believe that a

(5) heavy “rain” of gas is falling into many galaxies from

  the supposedly empty space around them. The gas

  apparently condenses into a collection of small stars,

  each a little larger than the planet Jupiter. These stars

  vastly outnumber the other stars in a given galaxy. The

(10) amount of “intergalactic rainfall” into some of these

   galaxies has been enough to double their mass in the

   time since they formed. Scientists have begun to suspect

   that this intergalactic gas is probably a mixture of gases

   left over from the “big bang” when the galaxies were

(15) formed and gas was forced out of galaxies by supernova

   explosions.

    It is well known that when gas is cooled at a constant

  pressure its volume decreases. Thus, the physicist Fabian

  reasoned that as intergalactic gas cools, the cooler gas

(20) shrinks inward toward the center of the galaxy. Mean-

  while its place is taken by hotter intergalactic gas from

  farther out on the edge of the galaxy, which cools as it is

  compressed and flows into the galaxy. The net result is a

  continuous flow of gas, starting as hot gases in inter-

(25) galactic space and ending as a drizzle of cool gas called a

   “cooling flow,” falling into the central galaxy.

    A fairly heretical idea in the 1970’s, the cooling-flow

   theory gained support when Fabian observed a cluster

   of galaxies in the constellation Perseus and found the

(30) central galaxy, NGC 1275, to be a strange-looking object

   with irregular, thin strands of gas radiating from it.

   According to previous speculation, these strands were

   gases that had been blown out by an explosion in the

   galaxy. Fabian, however, disagreed. Because the strands

(35) of gas radiating from NGC 1275 are visible in optical

  photographs, Fabian suggested that such strands consisted

  not of gas blown out of the galaxy but of cooling flows

  of gas streaming inward. He noted that the wavelengths

  of the radiation emitted by a gas would changes as the

(40) gas cooled, so that as the gas flowed into the galaxy and

  became cooler, it would emit not x-rays, but visible light,

  like that which was captured in the photographs. Fabian’s

  hypothesis was supported by Canizares’ determination in

  1982 that most of the gas in the Perseus cluster was at a

(45) temperature of 80 million degrees Kelvin, whereas the

  gas immediately surrounding NGC 1275 (the subject of

  the photographs) was at one-tenth this temperature.

1. The primary purpose of the passage is to

  (A) illustrate a hypothesis about the origin of galaxies

  (B) provide evidence to dispute an accepted theory

     about the evolution of galaxies

  (C) summarize the state of and prospects for research in

     intergalactic astronomy

  (D) report new data on the origins of intergalactic gas

  (E) reconcile opposing views on the formation of

     intergalactic gas

the correct answer is B,   我怎么没觉得他说了evolution of galaxies啊？ 我选C，我觉得主要是在说intergalactic

Passage 34

    Kazuko Nakane’s history of the early Japanese immi-

  grants to central California’s Pajaro
                Valley focuses on

  the development of farming communities there from

  1890 to 1940. The Issei (first-generation immigrants)

(5) were brought into the Pajaro Valley to raise sugar beets.

  Like Issei laborers in American cities, Japanese men in

  rural areas sought employment via the “boss” system.

  The system comprised three elements: immigrant wage

  laborers; Issei boardinghouses where laborers stayed;

(10) and labor contractors, who gathered workers for a

   particular job and then negotiated a contract between

   workers and employer. This same system was originally

   utilized by the Chinese laborers who had preceded the

   Japanese. A related institution was the “labor club,”

(15)which provided job information and negotiated employ-

   ment contracts and other legal matters, such as the

   rental of land, for Issei who chose to belong and paid an

   annual fee to the cooperative for membership.

   When the local sugar beet industry collapsed in 1902,

(20) the Issei began to lease land from the valley’s strawberry

   farmers. The Japanese provided the labor and the crop

   was divided between laborers and landowners. The Issei

   began to operate farms, they began to marry and start

   families, forming an established Japanese American

(30) community. Unfortunately, the Issei’s efforts to attain

   agricultural independence were hampered by govern-

   ment restrictions, such as the Alien Land Law of 1913.

   But immigrants could circumvent such exclusionary laws

   by leasing or purchasing land in their American-born

(35)
            children’s names.

     Nakane’s case study of one rural Japanese American

  community provides valuable information about the

  lives and experiences of the Isseil. It is, however, too

  particularistic. This limitation derives from Nakane’s

(40) methodology—that of oral history—which cannot

   substitute for a broader theoretical or comparative

   perspective. Furture research might well consider two

   issues raised by her study: were the Issei of the Pajaro

  Valley similar to or different from Issei in urban settings,

(45)
            and what variations existed between rural Japanese

   American communities?

1. The primary purpose of the passage is to

  (A) defend a controversial hypothesis presented in a

      history of early Japanese immigrants to Califronia

  (B) dismiss a history of an early Japanese settlement in

     California as narrow and ill constructed

  (C) summarize and critique a history of an early

     Japanese settlement in California

  (D) compare a history of one Japanese American

     community with studies of Japanese settlements

     throughout California

  (E) examine the differences between Japanese and

 Chinese immigrants to central California in the

 1890’s

答案是C，我选的D， 我觉得是在evaluate K所记录的历史啊？

summarize and critique a history 不靠谱儿啊

谢谢mm，但是正确答案的evolution of galaxies我也找不到相关
