阅读里有几个问题
Europa is the smallest of planet Jupiter’s four largest moons and the second moon
out from Jupiter. Until 1979, it was just another astronomy textbook statistic. Then
came the close-up images obtained by the exploratory spacecraft Voyager 2, and within
days, Europa was transformed-in our perception, at least-into one of the solar system’s
(5)most intriguing worlds. The biggest initial surprise was the almost total lack of detail,
especially from far away. Even at close range, the only visible features are thin, kinked
brown lines resembling cracks in an eggshell. And this analogy is not far off the mark.
The surface of Europa is almost pure water ice, but a nearly complete absence of
craters indicates that Europa’s surface ice resembles Earth’s Antarctic ice cap. The
(10) eggshell analogy may be quite accurate since the ice could be as little as a few kilometers
thick –a true shell around what is likely a subsurface liquid ocean that , in turn, encases
a rocky core. The interior of Europa has been kept warm over the eons by tidal forces
generated by the varying gravitational tugs of the other big moons as they wheel around
Jupiter. The tides on Europa pull and relax in an endless cycle. The resulting internal heat
(15) keeps what would otherwise be ice melted almost to the surface. The cracklike marks on
Europa’s icy face appear to be fractures where water or slush oozes from below.
Soon after Voyager 2’s encounter with Jupiter in 1979, when the best images of
Europa were obtained, researchers advanced the startling idea that Europa’s subsurface
ocean might harbor life. Life processes could have begun when Jupiter was releasing a
(20 )vast store of internal heat. Jupiter’s early heat was produced by the compression of the
material forming the giant planet. Just as the Sun is far less radiant today than the primal
Sun, so the internal heat generated by Jupiter is minor compared to its former intensity.
During this warm phase, some 4.6 billion years ago, Europa’s ocean may have been liquid
right to the surface, making it a crucible for life.
8. According to the passage, what is the effect of Jupiter’s other large moons on Europa?
(A) They prevent Europa’s subsurface waters from freezing.
(B) They prevent tides that could damage Europa’s surface.
(C) They produce the very hard layer of ice that characterizes Europa.
(D) They assure that the gravitational pull on Europa is maintained at a steady level.
答案是a,我选c,刚好相反,郁闷
The resulting internal heat keeps what would otherwise be ice melted almost to the surface. 意思是保持(本来应该是融化的),那不就是应该ice了》?
Native Americans probably arrived from Asia in successive waves over several
millennia, crossing a plain hundreds of miles wide that now lies inundated by 160 feet
of water released by melting glaciers. For several periods of time, the first beginning
around 60,000 B.C. and the last ending around 7,000 B.C., this land bridge was open. The
(5 )first people traveled in the dusty trails of the animals they hunted. They brought with them
not only their families, weapons, and tools but also a broad metaphysical understanding,
sprung from dreams and visions and articulated in myth and song, which complemented
their scientific and historical knowledge of the lives of animals and of people. All this they
shaped in a variety of languages, bringing into being oral literatures of power and beauty.
(10) Contemporary readers, forgetting the origins of western epic, lyric, and dramatic
forms, are easily disposed to think of “literature” only as something written. But on
reflection it becomes clear that the more critically useful as well as the more frequently employed sense of the term concerns the artfulness of the verbal creation, not its mode of presentation. Ultimately, literature is aesthetically valued, regardless of language, culture,
(15)or mode of presentation, because some significant verbal achievement results from the
struggle in words between tradition and talent. Verbal art has the ability to shape out a compelling inner vision in some skillfully crafted public verbal form.
Of course, the differences between the written and oral modes of expression are not without consequences for an understanding of Native American literature. The essential
(20)difference is that a speech event is an evolving communication, an “emergent form,” the shape, functions, and aesthetic values of which become more clearly realized over the
course of the performance. In performing verbal art , the performer assumes responsibility
for the manner as well as the content of the performance, while the audience assumes the responsibility for evaluating the performer’s competence in both areas. It is this intense
(25)mutual engagement that elicits the display of skill and shapes the emerging performance.
Where written literature provides us with a tradition of texts, oral literature offers a
tradition of performances.
35. What can be inferred about the nature of the Native American literature discussed in the passage?
(A) It reflects historical and contemporary life in Asia.
(B) Its main focus is on daily activities.
(C) It is based primarily on scientific knowledge.
(D) It is reshaped each time it is experienced.
在文章里面完全找不到。。。。选了个a,答案是d,再找,还是没找到答案 |
