Section A 26 Eat like a Greek, and it could cut your risk of having a heart attack, stroke, or dying from heart disease by about 30 perce
13、nt, according to an attention-grabbing【 C1】 _ published this week in the New England Journal of Medicine. While this is far from the first paper to find a【 C2】 _between the Mediterranean diet and heart health, it is unique because of its large size and design. It randomized a group of more than 7,00
14、0 people at high risk of heart disease to follow either one of two kinds of Mediterranean diets (one supplemented with olive oil and one with nuts) or a low-fat diet. This is the most【 C3】 _way to show that the diet itself was causing the differences in health outcomes. The【 C4】 _ in the study, men
15、and women between ages 55 and 80, had either type 2 diabetes or at least three major risk factors for heart disease, such as smoking, obesity, high blood pressure, high LDL cholesterol or low HDL cholesterol. So what did they eat, exactly? The two groups of【 C5】 _dieters were【 C6】_to eat fish and le
16、gumes three times a week, eat white meat instead of red, and avoid processed cookies and cakes. One group was told to use at least four tablespoons of extra virgin olive oil daily; the other was encouraged to eat an ounce of nuts each day. The low-fat dieters, it【 C7】 _out, actually didnt lower thei
17、r fat intake much. They basically ate their usual diet, including red meat, soda, and processed foods. 【 C8】 _with the group on the low-fat diet, the olive oil group had a 30 percent lower risk of heart attack, stroke or dying of heart disease after five years. Those in the nuts group had a 28 perce
18、nt lower risk. “The strength of this study comes from the fact that we measured hard outcomes and not just blood pressure or changes in【 C9】 _levels,“ study author Ramon Estruch, from the Department of Internal Medicine at the Hospital Clinic of Barcelona, told Time. com. “We really believe the Medi

The black-tailed deer, lowland, west-side cousin of th
21、e mule deer of eastern Washington, is now the most common. The other species, the Columbian white-tailed deer, in earlier times was common in the open prairie country, it is now restricted to the low, marshy islands and flood plains along the lower Columbia River. B) Nearly any kind of plant of the
22、forest understory can be part of a deers diet. Where the forest inhibits the growth of grass and other meadow plants, the black-tailed deer browses on huckleberry, salal, dogwood , and almost any other shrub or herb. But this is fair-weather feeding. What keeps the black-tailed deer alive in the har
23、sher seasons of plant decay and dormancy? One compensation for not hibernating is the built-in urge to migrate. Deer may move from high-elevation browse areas in summer down to the lowland areas in late fall. Even with snow on the ground, the high bushy understory is exposed; also snow and wind brin
24、g down leafy branches of cedar, hemlock, red alder, and other arboreal fodder. C) The numbers of deer have fluctuated markedly since the entry of Europeans into Puget Sound country. The early explorers and settlers told of abundant deer in the early 1800s and yet almost in the same breath bemoaned t
25、he lack of this succulent game animal. Famous explorers of the north American frontier , Lewis and Clark had experienced great difficulty finding game west of the Rockies and not until the second of December did they kill their first elk. To keep 40 people alive that winter, they consumed approximat
26、ely 150 elk and 20 deer. And when game moved out of the lowlands in early spring, the expedition decided to return east rather than face possible starvation. Later on in the early years of the nineteenth century, when Fort Vancouver became the headquarters of the Hudsons Bay Company, deer population
27、s continued to fluctuate. David Douglas, Scottish botanical explorer of the 1830s found a disturbing change in the animal life around the fort during the period between his first visit in 1825 and his final contact with the fort in 1832. A recent Douglas biographer states; “The deer which once pictu
28、resquely dotted the meadows around the fort were gone (in 1832), hunted to extermination in order to protect the crops.“ D) Reduction in numbers of game should have boded ill for their survival in later times. A worsening of the plight of deer was to be expected as settlers encroached on the land, l
29、ogging, burning, and clearing, eventually replacing a wilderness landscape with roads, cities, towns, and factories. No doubt the numbers of deer declined still further. Recall the fate of the Columbian white-tailed deer, now in a protected status. E) But for the black-tailed deer, human pressure ha
30、s had just the opposite effect. Wild life zoologist Hulmut Buechner (1953), in reviewing the nature of biotic changes in Washington through recorded time, Says that “since the early 1940s, the state has had more deer than at any other time in its history, the winter population fluctuating around app
31、roximately 320,000 deer (mule and black-tailed deer), which will yield about 65,000 of either sex and any age annually for an indefinite period. “ F) The causes of this population rebound are consequences of other human actions. First, the major predators of deer wolves, cougar, and lynx have been g
32、reatly reduced in numbers. Second, conservation has been insured by limiting times for and types of hunting. But the most profound reason for the restoration of high population numbers has been the gate of the forests. Great tracts of lowland country deforested by logging, fire, or both have become
33、ideal feeding grounds of deer. G) In addition to finding an increase of suitable browse, like huckleberry and vine maple, Arthur Einarsen, longtime game biologist in the Pacific Northwest, found quality of browse in the open areas to be substantially more nutritive. The protein content of shade-grow
34、n vegetation, for example, was much lower than that for plants grown in clearings. H) Deer are the ruminant mammals forming the family Cervidae. Species in the family include white-tailed deer, mule deer such as black-tailed deer, elk, moose, red deer, reindeer (caribou), fallow deer, roe deer and c
35、hital. I) Male deer of all species (except the Chinese water deer) and also female reindeer grow and shed new antlers each year. In this they differ from permanently horned animals such as antelope; these are in the same order as deer and may bear a superficial resemblance. The musk deer of Asia and
36、 water chevrotain (or mouse deer) of tropical African and Asian forests are not usually regarded as true deer and form their own families, Moschidae and Tragulidae, respectively. J) Deer are widely distributed, with indigenous representatives in all continents except Antarctica and Australia, though
37、 Africa has only one native species, the red deer, confined to the Atlas Mountains in the northwest of the continent. However, fallow deer have been introduced to South Africa. K) Deer live in a variety of biomes ranging from tundra to the tropical rainforest. While often associated with forests, ma
38、ny deer are ecotone species that live in transitional areas between forests and thickets (for cover) and prairie and savanna (open space). L) The majority of large deer species inhabit temperate mixed forest, mountain mixed coniferous forest, tropical seasonal/dry forest, and savanna habitats around
39、 the world. Clearing open areas within forests to some extent may actually benefit deer populations by exposing the understory and allowing the types of grasses, weeds, and herbs to grow that deer like to eat. M) Additionally, access to adjacent croplands may also benefit deer. However, adequate for
40、est or plants must still be provided for populations to grow and thrive. N) Small species of brocket deer and pudus of Central and South America, and muntjacs of Asia generally occupy dense forests and are less often seen in open spaces, with the possible exception of the Indian Muntjac. O) There ar
41、e also several species of deer that are highly specialized, and live almost exclusively in mountains, grasslands, swamps, and “wet“ savannas, or riparian corridors surrounded by deserts. Some deer have a circumpolar distribution in both North America and Eurasia. 37 The black-tailed deer has some re
42、lationship with the mule deer of eastern Washington. 38 Most of the male deer and part of the female deer grow and shed new antlers each year. 39 Deer may move from high-elevation browse areas in summer down to the lowland areas in late fall. 40 There are different species of deer, such as elk, moos
43、e, red deer, reindeer (caribou) , fallow deer, roe deer and chital. 41 The explorers killed approximately 150 elk and 20 deer to keep 40 people alive in that winter. 42 Arthur Einarsen, longtime game biologist in the Pacific Northwest, found quality of browse in the open areas to be substantially mo
44、re nutritive. 43 The deer may not have a good luck for their survival in the future, considering the reduction in numbers. 44 The causes of this population rebound are results of other human actions. 45 The places where the majority of large deer species inhabit are temperate mixed forest, mountain
45、mixed coniferous forest, tropical seasonal/dry forest, and savanna habitats around the world. 46 More than that, the access to croplands overlapping with the town would benefit deer. Section C 46 Spiders are known for many things. Sociability is not one of them. Most spiders are more likely to try t
46、o eat their neighbours than befriend them. Given that there are at least 43,678 species of spiders, though, it is not too surprising that a few have overcome their natural bad-temper and teamed up to form societies. So far, about two dozen such social spiders have been identified. And among them, so
47、mething really strange has just been found. For one type of spider society turns out to involve two different but closely related species. It is as though anthropologists (人类学家 )had discovered villages populated both by human beings and chimpanzees. This was discovered by a team led by Lena Grinsted
48、 of Aarhus University in Denmark. They were studying a social species of spider called Chikunia nigra, living near Beratan Lake in Bali. Later, as they looked in more detail at their samples, they realised its genes showed that it was actually two species. It is not clear why the spiders are social.
49、 They do not hunt together. One explanation may be that the colony is acting like a huge kindergarten. Ms. Grinsted discovered this possibility by experiment. First, she identified 19 females who were looking after those who were recently born, and another 20 who had eggs. In each case she introduced a new comer, in the form of a spider from the same colony. Both mothers and mothers-to-be were surprisingly tolerant of what would, in most spider species, be a serious threat. Only 40% of the time did they attem
