[求助]請教2002年8月reading問題
Question 10-19
Geographers say that what defines a place are four properties: soil, climate, altitude, and aspect, or attitude to the Sun. Florida’s ancient scrub demonstrates this principle. Its soil is pure silica, so barren it supports only lichens as ground cover.( It does, however, sustain a sand-swimming lizard that cannot live where there is moisture or plant matter the soil.) Its climate, despite more than 50 inches of annual rainfall, is blistering desert plant life it can sustain is only the xerophytic, the quintessentially dry. Its altitude is a mere couple of hundred feet, but it is high ground on a peninsula elsewhere close to sea level, and its drainage is so critical that a difference of inches in elevation can bring major changes in its plant communities. Its aspect is flat, direct, brutal—and subtropical. Florida’s surrounding lushness cannot impinge on its desert scrubbiness.
This does not sound like an attractive place. It does not look much like one either;Shrubby little oaks, clumps of scraggly bushes, prickly pear, thorns, and tangles. “It appear Said one early naturalist,” to desire to display the result of the misery through which it has Passed and is passing.” By our narrow standards, scrub is not beautiful; neither does it meet our selfish utilitarian needs. Even the name is an epithet, a synonym for the stunted, the scruffy, the insignificant, what is beautiful about such a place?
The most important remaining patches of scrub lie along the Lake Wales Ridge, a chain of paleoislands running for a hundred miles down the center of Florida, in most places less than ten miles wide. It is relict seashore, tossed up millions of years ago when ocean levels were higher and the rest of the peninsula was submerged. That ancient emergence is precisely what makes Lake Wales Ridge so precious: it has remained unsubmerged, its ecosystems essentially undisturbed, since the Miocene era. As a result, it has gathered to itself one of the largest collections of rare organisms in the world. Only about 75 plant species survive there, but at least 30 of these are found nowhere else on Earth.
12. It can be inferred from the passage that soil composed of silica
(A) does not hold moisture
(B) is found only in Florida
(C) nourishes many kinds of ground cover
(D) provides food for many kinds of lizards
答案;A
15. The author suggests that human standards of beauty are
(A) tolerant
(B) idealistic
(C) defensible
(D) limited
答案
19. The passage probably continues with a discussion of
(A) ancient scrub found in other areas of the country
(B) geographers who study Florida’s scrub
(C) the climate of the Lake Wales Ridge
(D) the unique plants found on the Lake Wales Ridge
答案
..............這題為何不能選A.因為當我在做時是想,最後段最後一句 it has gathered to itself one of the largest collections of rare organisms in the world. Only about 75 plant species survive there, but at least 30 of these are found nowhere else on Earth....講完了Lake Wales Ridge之後應該要討論別的地方.
~~另外還有這一回第47題有人誰答案有點問題,,是嗎~~
Question 41-50
The Moon, which has undergone a distinct and complex geological history, presents a striking appearance. The moon may be divided into two major terrains: the maria (dark lowlands) and the terrace( bright highlands). The contrast in the reflectivity (the capability of reflecting light ) of these two terrains suggested to many early observers that the two terrains might have different compositions, and this supposition was confirmed by missions to the Moon such as Surveyor and Apollo. One of the most obvious differences between the terrains is the smoothness of the maria in contrast to the roughness of the highlands. This roughness is mostly caused by the abundance of craters; the highlands are completely covered by large craters( greater than 40-50 km in diameter), while the craters of the maria tend to be much smaller. It is now known that the vast majority of the Moon’s craters were formed by the impact of solid bodies with the lunar surface.
Most of the near side of the Moon was thoroughly mapped and studied from telescopic pictures years before the age of space exploration. Earth-based telescopes can resolve objects as small as a few hundred meters on the lunar surface. Close observation of
craters, combined with the way the Moon diffusely reflects sunlight, led to the understanding that the Moon is covered by a surface layer, or regolith, that overlies the solid rock of the Moon. Telescopic images permitted the cataloging of a bewildering array of land forms. Craters were studied for clues to their origin; the large circular maria were seen.
47. All of the following terms are defined in the passage EXCEPT
(A) Moon (line1)
(B) reflectivity(line3)
(C) regolith(line16)
(D) rays(line19)
~~~答案給的是C...之前有人版上有人說是A...D這個選項文章沒有找到..行數不要看啦因為貼進來怪怪的,,,題目問的defined 就是我用黑字的地方...最後一段是剛好第20行 |
