题目：

Magazine commentary: If the major television networks acted responsibly, they would commit their most talented writers, directors and actors to create quality programs suitable for family viewing during "prime time" viewing hours each weekday evening. Instead, television programming is full of sex, violence, and adult situations and language. In fact, the most-watched programs are a situation comedy full of degrading and sexual humor and a police show with frequent violence and adult language. At present, only a few networks carry quality programs that are suitable for family viewing.
If you assume that the statements in the commentary are true, then which one of the following statements must also be true?

选项:

A、A. Children are being exposed to adult situations and language at a younger age.
B、B. Networks that carry programs unsuitable for family viewing are only concerned with the bottom line financially and do not act responsibly toward their viewing public.
C、C. Only a minority of families watch programs carried on public television stations.
D、D. Advertisers must put pressure on the major networks to carry more programs suitable for family viewing.
E、E. Most of the major networks are not meeting their responsibility to bring the public high quality programs suitable for family viewing.

文章：

State spokesperson：Many businesspeople who have not been to our state believe that we have an inadequate road system.Those people are mistaken, as is obvious from the fact that in each of the past six years, our state has spent more money per mile on road improvements than any other state.

题目：

Which of the following, if true, most seriously undermines the reasoning in the spokesperson's argument?

选项:

A、In the spokesperson's state, spending on road improvements has been increasing more slowly over the past six years than it has in several other states. Adequacy of a state's road system is generally less important to a businessperson considering doing business there than is the availability of qualified employees.
B、Over the past six years, numerous businesses have left the spokesperson's state, but about as many businesses have moved into the state.
C、In general, the number of miles of road in a state's road system depends on both the area and the population of the state.
D、Only states with seriously inadequate road systems need to spend large amounts of money on road improvements.

文章：

Line        In the Sonoran Desert of northwestern Mexico and
 southern Arizona, the flowers of several species of
 columnar cacti—cardon, saguaro, and organ
 pipe—were once exclusively pollinated at night by
(5)nectar-feeding bats, as their close relatives in arid
 tropical regions of southern Mexico still are. In these
 tropical regions, diurnal (daytime) visitors to columnar
 cactus flowers are ineffective pollinators because,
 by sunrise, the flowers' stigmas become unreceptive
(10)or the flowers close. Yet the flowers of the Sonoran
 Desert cacti have evolved to remain open after sunrise,
 allowing pollination by such diurnal visitors as bees and
 birds. Why have these cacti expanded their range of
 pollinators by remaining open and receptive in daylight?
(15)     This development at the northernmost range of
 columnar cacti may be due to a yearly variation in the
 abundance—and hence the reliability—of migratory
 nectar-feeding bats. Pollinators can be unreliable
 for several reasons. They can be dietary generalists
(20)whose fidelity to a particular species depends on
 the availability of alternative food sources. Or, they
 can be dietary specialists, but their abundance may
 vary widely from year to year, resulting in variable
 pollination of their preferred food species. Finally, they
(25)may be dietary specialists, but their abundance may
 be chronically low relative to the availability of flowers.
      Recent data reveals that during spring in the
 Sonoran Desert, the nectar-feeding bats are
 specialists feeding on cardon, saguaro, and
(30)organpipe flowers. However, whereas cactus-flower
 abundance tends to be high during spring, bat
 population densities tend to be low except near
 maternity roosts. Moreover, in spring, diurnal cactus-
 pollinating birds are significantly more abundant in
(35)this region than are the nocturnal bats. Thus, with bats
 being unreliable cactus-flower pollinators, and daytime
 pollinators more abundant and therefore more reliable,
 selection favors the cactus flowers with traits that
 increase their range of pollinators. While data suggest
(40)that population densities of nectar-feeding bats are
 also low in tropical areas of southern Mexico, where
 bats are the exclusive pollinators of many species
 of columnar cacti, cactus-flower density and bat
 population density appear to be much more evenly
(45)balanced there: compared with the Sonoran Desert's
 cardon and saguaro, columnar cacti in southern Mexico
 produce far fewer flowers per night. Accordingly,
 despite their low population density, bats are able to
 pollinate nearly 100 percent of the available flowers.

According to the passage, present-day columnar cacti in the Sonoran Desert differ from their close relatives in southern Mexico in that the Sonoran cacti

Physician: The hormone melatonin has shown promise as a medication for sleep disorders when taken in synthesized form. Because the long-term side effects of synthetic melatonin are unknown, however, I cannot recommend its use at this time. Patient: Your position is inconsistent with your usual practice. You prescribe many medications that you know have serious side effects, so concern about side effects cannot be the real reason you will not prescribe melatonin.

题目：

The patient’s argument is flawed because it fails to consider that

选项:

A、the side effects of synthetic melatonin might be different from those of naturally produced melatoninit is possible that the physician does not believe that melatonin has been conclusively shown to be effectiv

题目：

To prevent a newly built dam on the Chiff River from blocking the route of fish migrating to breeding grounds upstream, the dam includes a fish pass, a mechanism designed to allow fish through the dam. Before the construction of the dam and fish pass, several thousand fish a day swam upriver during spawning season. But in the first season after the project's completion, only 300 per day made the journey. Clearly, the fish pass is defective.

文章：

Maps made by non-Native Americans to depict Native American land tenure, resources andpopulation distributions appeared almost as early as Europeans' first encounters with NativeAmericans and took many form: missionaries' field sketches, explorers' drawings, and surveyors'maps, as well as maps rendered in connection with treaties involving land transfers. Most existingmaps of Native American lands are reconstructions that are based largely on archaeology, oralreports, and evidence gathered from observers' accounts in letter, diaries, and official reports;accordingly, the accuracy of these maps is especially dependent on the mapmakers' owninterpretive abilities.

Many existing maps also reflect the 150-year role of the Bureau of Indian Affairs (BIA) in administering tribal lands. Though these maps incorporate some information gleaned directly from Native Americans, rarely has Native American cartography contributed to this official record, which has been compiled, surveyed, and authenticated by non-Native American tribes and their migrations and cultural features, as well as territoriality and contemporary trust lands, reflects the origins of the data, the mixed purposes for which the maps have been prepared, and changes both I United States government policy and in non-Native Americans’ attitudes toward an understanding of Native Americans.

题目：

Which of the following best describes the content of the passage?

选项:

A、A chronology of the development of different methods for mapping Native AmericansA discussion of how the mapmaking techniques of Native Americans differed from those of Europeans
B、An argument concerning the presenta-day uses to which historical maps of Native American lands are put
C、An argument concerning the nature of information contained in maps of Native American lands
D、A proposal for improving the accuracy of maps of Native American lands

Art historian: Unlike many artistic traditions that sought to depict plants native to the local area in a seasonally appropriate way (for example, depicting scenes of spring with the plants in the appropriate stages of development for that season), seventeenth-century Dutch artists specializing in flower paintings almost exclusively chose to depict exotic species of flowers from outside the local area. Painting such species was worthwhile primarily because the art-buying public had developed a strong preference for images of the exotic. The great botanical centers of the time gave the artists direct access to such flowers, which the artists would freely combine in a single painting, regardless of whether the combined species occurred together in the wild, and depicted each in full bloom, regardless of whether those species bloomed at the same time in nature.

Statement: The art historian makes the point that the species of flowers these Dutch artists chose to paint were 1 largely because the species were 2 .

Select for 1 and for 2 the options that complete the statement so that it is most strongly supported by the information provided. Make only two selections, one in each column.

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.
 
Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
