26、ew about plants,but from what we can observe of pre-industrial societies that still exist,a detailed learning of plants and their properties must be extremely ancient.This is logical.Plants are the basis of the food pyramid for all living things,even for other plants.They have always been important
27、to the benefit of people,not only for food,but also for clothing,weapons,tools,dyes,medicines,shelters,and a great many other purposes.Tribes living today in the jungles of the Amazon recognize hundreds of plants and know many properties of each.To them,botany has no name and is probably not even re
28、cognized as a special branch of “knowledge”at all.Unfortunately,the more industrialized we become the farther away we move from direct contact with plants,and the less definite our knowledge,and few people will fail to recognize a rose,an apple,or an orchid.When our ancestors,living in the Middle Ea
29、st about 10,000 years ago,discovered that certain grasses could be harvested and their seeds planted for richer harvests the next season,the first great step in a new association(联系)of plants and humans was taken.Grains were discovered and from them flowed the wonder of agriculture:cultivated crops.
30、From then on,humans would increasingly take their living from the controlled production of a few plants,rather than getting a little here and a little there from many varieties that grew wildand the accumulated(积累)knowledge of tens of thousands of years of experience and close contact with plants in

35、ind the active ingredient,which is the chemical in the plant that works to heal.Many of the drugs we use,including aspirin,have come from these natural medicines.In recent years,many people in the USA have been taking what are legally known as dietary supplements.They may be vitamins or minerals.The
36、y may be herbs that help with health problems,such as depression.Some of them are teas.Others are capsules or tablets.They are sold in natural food stores,drug stores,and groceries.Most people think that because these products are natural and they are also safe.This is not always true.There are many
37、 plants that are poisonous.There are others that have bad side effects.The New England Journal of Medicine publishes medical research.A recent edition called for the government to regulate dietary supplements.Several doctors wrote to the journal and told of bad experiences people have had with dieta
38、ry supplements.Dietary supplements arent tested in the same way as drugs.There is not always proof that the supplement really does what it is supposed to do.There is also a problem with purity of the supplement.Supplements have been found to contain things that are bad for the body.For example,the C
39、alifornia Department of Public Health found that of 260 herbs grown in China,one-third contained heavy metals.They are minerals such as lead and mercury.They are very poisonous,even in tiny amounts.24.The scientists study the cures from the healers in order to .

A.it is legal to take dietary supplements in the Uni
41、ted StatesB.supplements are safe because they are natural medicinesC.all the supplements are poisonousD.none of the supplements has bad side effects答案:A解析:推理判断题。从第二段我们可知,在美国吃补药是合法的。26.The problem with dietary supplements may be in that .

44、指人们认为补药中含有维生素和矿物质;D 项指有些补药对你的身体有害,这些选项都和原文相符,都是正确的。CThe male lions splendid mane(鬃毛 )sets him apart from other catsand its great attraction for the ladiesso why would he do without it?That question has puzzled scientists since 1833,when the first reports of“maneless”lions streamed in from around the
45、 world.Now,a research team reports that lions from the Tsavo region of Kenya deliberately delay mane growth to fit in with the regions harsh temperatures.John Patterson,a hunter and a British Colonel,was one of the first to document manelessness in Tsavos famous man-eaters.Ever since,naturalists hav
46、e developed evolutionary descriptions.Some researchers suggested that lions lost their manes because they were caught too many times in Tsavos thorn bushes everywhere.Others argued that Tsavos aggressive lions have unusually high testosterone(雄激素)levels,known to cause male pattern baldness(秃顶)in hum
47、ans.Still others supposed that Tsavos lions were a distinct group or were a related to a lion pictured in prehistoric caves,which no longer existed.But expert Thomas Gnoske at the Field Museum in Chicago,Illinois,considered something these researchers didnt:lions shipped to zoos in cooler climates g
48、row longer manes.This made him wonder whether hot temperatures account for Tsavos thinning lions.To find out,Gnoske and his colleagues studied museum records and conducted 10 years of fieldwork in Tsavo and in the Serengeti,which is about 10 degrees cooler.In an article published online this month i
49、n the Journal of Zoology,the team reports that lions in the Serengeti grow a full mane in 5 yearsby the time theyre ready to breedbut that Tsavos lions dont have much of mane until age 8,well past their reproductive period.Gnoske thinks smaller manes improve a young,energetic lions ability to keep cool.Bushy manes probably evolved to attract females in cooler climates where heat stress was not an issue,Gnoske says,and lions cant just turn off that program,now that theyre in a place like Tsavo.“Theyre
