[单项选择] It used to be so straightforward. A team of researchers working together in the laboratory would submit the results of their research to a journal. A journal editor would then remove the authors’ names and affiliations from the paper and send it to their peers for review. Depending on the comments received, the editor would accept the paper for publication or decline it. Copyright rested with the journal publisher, and researchers seeking knowledge of the results would have to subscribe to the journal. No longer. The Internet—and pressure from funding agencies, who are questioning why commercial publishers are making money from government-funded research by restricting access to it—is making access to scientific results a reality. The Organization for Economic Co-operation and Development (OECD) has just issued a report describing the far-reaching consequences of this. The report, by John Houghton of Victoria University in Australia and Graham Vickery of the OECD, makes heavy

[简答题]On each side of a bright river he saw rise a line of brighter palaces, arched and pillared, and inlaid with deep red porphyry, and with serpentine; along the quays before their gates were riding troops of knights, noble in face and form, dazzling in crest and shield; horse and man one labyrinth of quaint color and gleaming light -- the purple, and silver, and scarlet fringes flowing over the strong limbs and clashing mail, like sea-waves over rock at sunset. Opening on each side from the river were gardens, courts, and cloisters; long successions of white pillars among wreaths of vine; leaping of fountains through buds of pomegranate and orange; and still a- long the garden-paths, and under and through the crimson of the pomegranate shadows, moving slowly, groups of the fairest women that Italy ever saw--fairest, because purest and most thoughtful; trained in all high knowledge, as in all courteous art--in dance, in song, in sweet wit, in lofty learning, in loftier courage, in loftiest

[不定项选择题]共用题干 第二篇

Don ' t Count on Dung

" Conservationists(自然保护主义者)may be miscalculating the numbers of the threatened animals such
as elephants."say African and American researchers.The error occurs because of a flaw in the way that they
estimate animal numbers from the piles of dung(粪)the creatures leave behind.
The mistake could lead researchers to think that there are twice as many elephants as there really are in
some regions,according to Andrew Plumptre of the Wildlife Conservation Society(WCS)in New York.
Biologist Katy Payne of Cornell University in Ithaca,New York,agrees."We really need to know ele-
phant numbers and the evidence that we have is quite indirect,"says Payne,who electronically
tracks elephants.
Counting elephants from planes is impossible in the vast rainforests of Central Africa. So researchers of-
ten estimate elephant numbers by counting dung piles in a given area.They also need to know the rate at
which dung decays.Because it's extremely difficult to determine these rates,researchers counting elephants
in one region tend to rely on standard decay rates established elsewhere.
But researchers at the WCS have found that this decay rate varies from region to region depending on the
climate and environment. " Using the wrong values can lead the census astray(离开正道),"says Plumptre.
He and his colleague Anthony Chifu Nchanji studied decaying elephant dung in the forests of Came-
roon.They found that the dung decayed between 55 and 65 per cent more slowly than the dung in the
rainforests of neighbouring Gabon.If researchers use decay rates from Gabon to count elephants in Cameroon,
they would probably find more elephants than are actually around."This could mean estimates in Cameroon
are at least twice as high as those derived from decay rates calculated locally,"says Plumptre."However
accurate your dung density estimate might be,the decay rate can severely affect the result."
Plumptre also says that the dung-pile census should be carried out over a region similar in size to an ele-
phant's natural range."The usual technique of monitoring only small,protected areas distorts numbers be-
cause elephants move in and out of these regions,"he says."If the elephant population increases within the
protected area,you cannot determine whether it is a real increase or whether it is due to elephants moving in
because they are being poached(入侵偷猎)outside."
Plumptre says that similar problems may also affect other animal census studies that rely on indirect evi--
dence such as nests,tracks or burrows(地洞). According to Plumptre,the region over which a dung-pile census is carried out should be_________.
A.small enough
B.well protected
C.carefully monitored
D.large enough
