22、ten blanks.You are required to select one word for each blank from a list of choices given in a word bank following the passage.Read the passage through carefully before making your choices.Each choice in the bank is identified by a letter.Please mark the corresponding letter for each item on Answer
23、 Sheet 2 with a single line through the centre.You may not use any of the words in the bank more than once.Did Sarah Josepha Hale write Marys Little Lamb,the eternal nursery rhyme(儿歌)about a girl named Mary with a stubborn lamb?This is still disputed,but its clear that the woman 26 for writing it wa
24、s one of Americas most fascinating 27.In honor of the poems publication on May 24,1830,heres more about the 28 authors life.Hale wasnt just a writer,she was also a 29 social advocate,and she was particularly 30 with an ideal New England,which she associated with abundant Thanksgiving meals that she
25、claimed had a deep moral influence.She began a nationwide 31 to have a national holiday declared that would bring families together while celebrating the 32 festivals.In 1863,after 17 years of advocacy including letters to five presidents,Hale got it.President Abraham Lincoln,during the Civil War,is
26、sued a 33 setting aside the last Thursday in November for the holiday.The true authorship of Marys Little Lamb is disputed.According to the New England Historical Society,Hale wrote only part of the poem,but claimed authorship.Regardless of the author,it seems that the poem was 34 by a real event.Wh
27、en young Mary Sawyer was followed to school by a lamb in 1816,it caused some problems.A bystander named John Roulstone wrote a poem about the event,then,at some point,Hale herself seems to have helped write it.However,if a 1916 piece by her great-niece is to be trusted,Hale claimed for the 35 of her

30、letter on Answer Sheet 2.Grow Plants Without Water A)Ever since humanity began to farm our own food,we ve faced the unpredictable rain that is both friend and enemy.It comes and goes without much warning,and a field of lush(茂盛的)leafy greens one year can dry up and blow away the next.Food security an
31、d fortunes depend on sufficient rain,and nowhere more so than in Africa,where 96%of farmland depends on rain instead of the irrigation common in more developed places.It has consequences:South Africas ongoing droughtthe worst in three decades will cost at least a quarter of its corn crop this year.B
32、)Biologist Jill Farrant of the University of Cape Town in South Africa says that nature has plenty of answers for people who want to grow crops in places with unpredictable rainfall.She is hard at work finding a way to take traits from rare wild plants that adapt to extreme dry weather and use them
33、in food crops.As the earths climate changes and rainfall becomes even less predictable in some places,those answers will grow even more valuable.The type of farming Im aiming for is literally so that people can survive as its going to get more and more dry,Farrant says.C)Extreme conditions produce e
34、xtremely tough plants.In the rusty red deserts of South Africa,steep-sided rocky hills called inselbergs rear up from the plains like the bones of the earth.The hills are remnants of an earlier geological era,scraped bare of most soil and exposed to the elements.Yet on these and similar formations i
35、n deserts around the world,a few fierce plants have adapted to endure under ever-changing conditions.D)Farrant calls them resurrection plants(复苏植物).During months without water under a harsh sun,they wither,shrink and contract until they look like a pile of dead gray leaves.But rainfall can revive th
36、em in a matter of hours.Her time-lapse(间歇性拍摄的)videos of the revivals look like someone playing a tape of the plants death in reverse.E)The big difference between drought-tolerant plants and these tough plants:metabolism.Many different kinds of plants have developed tactics to weather dry spells.Some
37、 plants store reserves of water to see them through a drought;others send roots deep down to subsurface water supplies.But once these plants use up their stored reserve or tap out the underground supply,they cease growing and start to die.They may be able to handle a drought of some length,and many
38、people use the term drought tolerant to describe such plants,but they never actually stop needing to consume water,so Farrant prefers to call them drought resistant.F)Resurrection plants,defined as those capable of recovering from holding less than 0.1 grams of water per gram of dry mass,are differe
39、nt.They lack water-storing structures,and their existence on rock faces prevents them from tapping groundwater,so they have instead developed the ability to change their metabolism.When they detect an extended dry period,they divert their metabolisms,producing sugars and certain stress-associated pr
40、oteins and other materials in their tissues.As the plant dries,these resources take on first the properties of honey,then rubber,and finally enter a glass-like state that is the most stable state that the plant can maintain,Farrant says.That slows the plants metabolism and protects its dried-out tis
41、sues.The plants also change shape,shrinking to minimize the surface area through which their remaining water might evaporate.They can recover from months and years without water,depending on the species.G)What else can do this dry-out-and-revive trick?Seeds almost all of them.At the start of her car
42、eer,Farrant studied recalcitrant seeds(顽 拗 性 种 子),such as avocados,coffee and lychee.While tasty,such seeds are delicatethey cannot bud and grow if they dry out(as you may know if youve ever tried to grow a tree from an avocado pit).In the seed world,that makes them rare,because most seeds from flow
43、ering plants are quite robust.Most seeds can wait out the dry,unwelcoming seasons until conditions are right and they sprout(发芽).Yet once they start growing,such plants seem not to retain the ability to hit the pause button on metabolism in their stems or leaves.H)After completing her Ph.D.on seeds,
44、Farrant began investigating whether it might be possible to isolate the properties that make most seeds so resilient(迅速恢复活力的)and transfer them to other plant tissues.What Farrant and others have found over the past two decades is that there are many genes involved in resurrection plants response to
45、dryness.Many of them are the same that regulate how seeds become dryness-tolerant while still attached to their parent plants.Now they are trying to figure out what molecular signaling processes activate those seed-building genes in resurrection plants and how to reproduce them in crops.Most genes a
46、re regulated by a master set of genes,Farrant says.Were looking at gene promoters and what would be their master switch.I)Once Farrant and her colleagues feel they have a better sense of which switches to throw,they will have to find the best way to do so in useful crops.Im trying three methods of b
47、reeding,Farrant says:conventional,genetic modification and gene editing.She says she is aware that plenty of people do not want to eat genetically modified crops,but she is pushing ahead with every available tool until one works.Farmers and consumers alike can choose whether or not to use whichever
48、version prevails：Im giving people an option.J)Farrant and others in the resurrection business got together last year to discuss the best species of resurrection plant to use as a lab model.Just like medical researchers use rats to test ideas for human medical treatments,botanists use plants that are
49、 relatively easy to grow in a lab or greenhouse setting to test their ideas for related species.The Queensland rock violet is one of the best studied resurrection plants so far,with a draft genome(基 因 图 谱)published last year by a Chinese team.Also last year,Farrant and colleagues published a detaile
50、d molecular study of another candidate,Xerophyta viscosa,a tough-as-nail South African plant with lily-like flowers,and she says that a genome is on the way.One or both of these models will help researchers test their ideasso far mostly done in the lab on test plots.K)Understanding the basic science
