请判断并选择下面这段文字的写作逻辑: We highlight the need to integrate belowground organisms into biodiversity research, despite differences in the scale of sampling, if we are to fully understand large-scale patterns of biodiversity and their underlying drivers, especially if processes underlying macroecological patterns differ between aboveground and belowground diversity. The inclusion of soil taxa may alter the distribution of biodiversity hotspots and conservation priorities. For example, protected areas may not be protecting earthworms, despite their importance as ecosystem function providers and soil ecosystem engineers for other organisms. By modeling both realms, aboveground/belowground comparisons are possible, potentially allowing a clearer view of the biodiversity distribution of whole ecosystems.
A、Specific to General
B、Problem to Solution
C、Process
D、Old to New

根据下列短文,回答下列各题。 Despite the fact that today viruses(病毒)are known to cause cancer in animals and incertain plants,there exists a great reluctance to accept viruses as being of importance in humancancer.Basic biological phenomena generally do not differ strikingly as one goes from one spe—cies to another.It should be recognized that cancer is a biological problem and not a problemthat is unique for man.Cancer originates when a normal cell suddenly becomes a cancer cellwhich multiplies widely and without apparent restraint.Cancer may originate in many differentkinds of cell,but the cancer cell usually continues to carry certain traits(特性)of the cell of origin.The transformation of a normal cell into a cancer cell may have more than one kind of cause.but there is good reason to consider the relationships that exist between viruses and cancer. Since there is no evidence that human cancer,as generally experienced,is infections,manypersons believe that because viruses are infections agents they cannot possibly be of importancein human cancer.However,viruses can mutate(突变)and examples are known in which a vi.rus that never kills its host can mutate to form. a new strain of virus that always kills its host.Itdoes not seem unreasonable to assume that an innocuous(无害的)latent(潜伏的)virus mightmutate to form. a strain that causes cancer.Certainly the experimental evidence now available isconsistent with the idea that viruses as we know them today,could be the causative(引起……的)agents of most,if not all cancer。including cancer in mall. Cancer should be considered to be a biological problem rather than a medical one because_________.
A.viruses are known to cause cancer in animals
B.at present,human cancer is not believed to be contagious(传染的)
C.there are many known causes for the transformation of a normal cell to a cancer cell
D.results of experiments on plants and animals do not vary greatly from species to species

D.To find out whether they differ in their preference for musical instruments.

High Stress May Damage Memory
According to a report issued in May 1998,elderly people who have consistently high b1ood levels of cortisol don’t score as well on memory tests as their peels with lower levels of the stress hormone.What’s more. high 1evels of cortisol are also associated with shrinking 0f the hippocampus,a region of the brain that plays a key role in learning and memory.The 6ndings suggest that even cortisol levels in the normal,“healthy” range can actually accelerate brain aging.
The study results “now provide substantial evidence that long—term exposure to adrenal stress hormones may promote hippocampal aging in normal elderly humans,”write Nada Porter and Philip Landfield of the University of Kentucky in Lexington in their editorial.Cortisol is a hormone released in response to stress by the adrenal glands,which sit on top of the kidneys.
Over a 5 to 6一year period,Dr. Sonia Lupien and his colleagues measured 24一hour cortisol levels in 51 healthy volunteers,most of Whom were in their 70s.
Despite wide variation in cortisol levels.the participants could be divided into three Subgroups:those whose cortisol progressively increased over time and was currently high(increasing/high):those whose cortisol progressively increased over time and was currently moderate(increasing/moderate);and subjects whose cortisol decreased,but Was currently moderate(decreasing/moderate).
The researchers tested the volunteers’ memory on six people in the increasing/high category and five people in the decreasing/moderate group.The groups did not differ on tests of immediate memory,but the increasing/high cortisol group had other memory problems compared with those in the decreasing/moderate group.
The researchers also found that the total volume of the hippocampus in those in the increasing/high group was 14% lower than those in the decreasing/moderate group,although there were no differences in 0ther brain regions.
The results suggest that brain aging Can be accelerated by levels of adrenal hormones that are not generally regarded as pathological and that variation within this normal range is related to variation in the rate of brain aging.”write Porter and Landfield.“This further suggests that chronic stress may accelerate the worsening of hippocampus.”
第 26 题 The part of the brain important for a person’s learning and memory is.
A.the cortisol.
B.the adrenal glands.
C.the stress hormones
D.the hippocampus.
The term "information age" probably does not do justice to the possibilities of this emerging era. 【102】This is an age of "knowledge and distributed intelligence," in which knowledge is available to anyone,located anywhere, at any time; and in which power, information, and control are moving from centralized systems to individuals. This era calls for a new form. of leadership and vision from the academic science and engineering community. We know from countless examples that academic science the engineering have enabled our society to make the most of new technologies. We wouldn't have today's advanced computer graphics systems if mathematicians hadn't been able to solve problems related to surface geometries. 【103】We wouldn't have networks capable of handling massive amounts of dare if physicists and astronomers hadn't continuously forged tools to look more deeply into subatomic structures and the cosmos.
Chemists' efforts to simulate complex phenomena and predict the properties of many-electron systems have inspired massively parallel architectures for computing. 【104】And the information made available by the sequencing of the human genome has caused us to rethink how to store, manipulate, and retrieve data most effectively. It will take new insights from studies of human cognition, linguistics, neurobiology, computing, and more to develop systems that truly augment our capacity to learn and create. The best may be yet to come.
Despite brutally tight constraints on federal discretionary spending, President Clinton has stepped forward to champion a 3 percent increase (uncorrected for inflation) in the 1998 budget of NSF (美国国家科学基金会). The president's request is only the first step in the congressional budget process ahead. 【105】Given that the priorities of Congress will almost certainly differ from those of the president, it will take an unprecedented level of input and commitment from the research community to ensure that investments in science and engineering receive the same strong bipartisan support they have enjoyed for generations. This 3 percent increase would enable NSF to launch a new set of investments spanning all its directorates.
