TPO17第二篇阅读13题        

Less colorful birds and animals that inhabit the rain forest tend to rely on forms of signaling other than the visual, particularly over long distances.
        ■ The piercing cries of the rhinoceros hornbill characterize the Southeast Asian rain forest, as do the unmistakable calls of the gibbons. ■In densely wooded environments, sound is the best means of communication over distance because in comparison with light, it travels with little impediment from trees and other vegetation. ■In forests, visual signals can be seen only at short distances, where they are not obstructed by trees. ■The male riflebird exploits both of these modes of signaling simultaneously in his courtship display. The sounds made as each wing is opened carry extremely well over distance and advertise his presence widely. The ritualized visual display communicates in close quarters when a female has approached.
        13. Look at the four squares ■ that indicate where the following sentence could be added to the passage.
        There is also the long, rather terrifying call of the male orangutan, which carries over considerable distances to advertise his presence.
        Where would the sentence best fit?
我选的D,答案B
当初看到BOTH，发现选项有also，又想到short distanct和选项 long，对应 就选了4.
现在看来，piercing cries 和terrifying call 也是对应的。also其实是指另外一种，是顺承。5. Which of the following can be concluded from the discussion in paragraph 3 about the Australian rabbit population?
        ○ Human intervention may alter the host, the parasite, and the relationship between them
        ○ The risks of introducing outside organisms into a biological community are not worth the benefits.
        ○Humans should not interfere in host-parasite relationships.
        ○ Organisms that survive a parasitic attack do so in spite of the natural selection process.
        paragraph 3 At times, it is actually possible to watch the effects of natural selection in host-parasite relationships. For example, Australia during the 1940 s was overrun by hundreds of millions of European rabbits. The rabbits destroyed huge expanses of Australia and threatened the sheep and cattle industries. In 1950, myxoma virus, a parasite that affects rabbits, was deliberately introduced into Australia to control the rabbit population. Spread rapidly by mosquitoes, the virus devastated the rabbit population. The virus was less deadly to the offspring of surviving rabbits, however, and it caused less and less harm over the years. Apparently, genotypes (the genetic make-up of an organism) in the rabbit population were selected that were better able to resist the parasite. Meanwhile, the deadliest strains of the virus perished with their hosts as natural selection favored strains that could infect hosts but not kill them. Thus, natural selection stabilized this host-parasite relationship.
答案是A
Human intervention may alter the host, the parasite, and the relationship between them。求解释啊。虽然。deliberately可以看出人有影响。。但是最后的H-P relationship 不是没有改变，只是稳定了。。。
OG阅读练习4
Paragraph 5: Although early exhibitors regularly accompanied movies with live acts, the substance of the movies themselves is mass-produced, prerecorded material that can easily be reproduced by theaters with little or no active participation by the exhibitor. Even though early exhibitors shaped their film programs by mixing films and other entertainments together in whichever way they thought would be most attractive to audiences or by accompanying them with lectures, their creative control remained limited. What audiences came to see was the technological marvel of the movies; the lifelike reproduction of the commonplace motion of trains, of waves striking the shore, and of people walking in the street; and the magic made possible by trick photography and the manipulation of the camera.




7. According to paragraph 5, what role did early exhibitors play in the presentation of movies in theaters?

○They decided how to combine various components of the film program.

○They advised film-makers on appropriate movie content.

○They often took part in the live-action performances.

○They produced and prerecorded the material that was shown in the theaters.
当初看到 Although early exhibitors regularly accompanied movies with live acts选了C。结果答案说
Even though early exhibitors shaped their film programs by mixing films and other entertainments together 。选A。。
求解释

Paragraph 6: With the advent of projection, the viewer's relationship with the image was no longer private, as it had been with earlier peepshow devices such as the Kinetoscope and the Mutoscope, which was a similar machine that reproduced motion by means of successive images on individual photographic cards instead of on strips of celluloid.
It suddenly became public-an experience that the viewer shared with dozens, scores, and even hundreds of others. At the same time, the image that the spectator looked at expanded from the minuscule peepshow dimensions of 1 or 2 inches (in height) to the life-size proportions of 6 or 9 feet.






8. Which of the following is mentioned in paragraph 6 as one of the ways the Mutoscope differed from the Kinetoscope?

○Sound and motion were simultaneously produced in the Mutoscope.

○More than one person could view the images at the same time with the Mutoscope.

○The Mutoscope was a less sophisticated earlier prototype of the Kinetoscope.

○A different type of material was used to produce the images used in the Mutocope.





9. The word it in the passage refers to

○The advent of projection

○The viewer's relationship with the image

○A similar machine

○Celluloid

○1

This is a Factual Information question asking for specific information that can
be found in paragraph 5. The correct answer is choice 1, "They decided how to
combine various components of the film program," because that idea is stated
explicitly in the paragraph:

"Early exhibitors shaped their film programs by mixing films and other entertainments together."

The other choices, while possibly true, are not explicitly mentioned in the
paragraph as being among the exhibitors' roles.

8.
○4

This is a Factual Information question asking for specific information that can
be found in paragraph 6. The correct answer is choice 4, "A different type of material
was used to produce the images used in the Mutoscope." The paragraph says
that these machines were very similar but that they differed in one particular way:

". . . the Mutoscope, which was a similar machine that reproduced motion by means of successive
images on individual photographic cards instead of on strips of celluloid."

9.
○2

This is a Reference question. The word being tested is it. That word is highlighted
in the passage. Choice 2, "the viewer's relationship with the image," is the
correct answer. This is a simple-pronoun referent item. The sentence says that "it"
suddenly became "public," which implies that whatever "it" is, it was formerly private.
The paragraph says that the "viewer's relationship to the image was no
longer private," so that relationship is the "it" referred to here.
