26、the eternal nursery rhyme (儿歌) about a girl named Mary with a stubborn lamb? This is still dispute , but it’s clear that the woman 26 for writing it was one of America 's most fascinating 27 _. In honor of the poem 's publication on May 24,1830, here’s more about the 28 author 's li

27、fe. Hale wasn’t 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 claimed had “a deep moral influence.” she began a nationwide 31 to have a national holiday dec

28、lared 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, issued a 33 the holiday. setting aside the last Thursday in November

29、for The true authorship of “Mary’s Little Lamb” is disputed.. According to New England Historical Society, Hale wrote only one part of the poem, but claimed authorship. Regardless of the author, it seems that the poem was 34 by a real event. When young Mary Sawyer was followed to

30、 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 her life that “Some other p

31、eople pretended that someone else wrote the poem”. 35 of A). campaign B). career C). characters D). features E). fierce F). inspired G). latter H). obsessed I). proclamation J). rectified K). reputed L). rest M). supposed N). traditional O). versatile Section B Directi

32、ons: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a lette

33、r. Answer the questions by marking the corresponding letter on Answer Sheet2. 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 (茂盛旳) l

34、eafy greens one year can dry up and blow away the next. Food security and 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 Africa's ongoing drought—th

35、e worst in three decades— will cost at least a quarter of its com crop this year. [B]. 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

36、 finding a way to take traits from rare wild plants that adapt to extreme dry weather and use them in food crops. As the earth's climate changes and rainfall becomes even less predictable in some places, those answers will grow even more valuable."The type of farming I'm aiming for is literall

37、y so that people can survive as it's going to get more and more dry,"Farrant says. [C]. Extreme conditions produce extremely 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 remn

38、ants of an earlier geological era, scraped bare of most soil and exposed to the elements. Yet on these and similar formations in 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 wi

39、thout water under a harsh sun. They wither, shrink and contract until they look like a pile of dead gray leaves. But rainfall can revive them in a matter of hours. Her time-lapse (间歇性拍摄旳) videos of the revivals look like someone playing a tape of the plant's death in reverse. [E]. The big d

40、ifference between "drought-tolerant" plants and these tough plants: metabolism. Many different kinds of plants have developed tactics to weather dry spells. Some plants store reserves of water to see them through a drought ; others send roots deep down to subsurface water supplies. But once the

41、se 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 people use the term "drought tolerant" to describe such plants, but they never actually stop needing to consume water, so Fa

42、rrant 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 different. They lack water-storing structures, and their existence on rock faces prevents them from tapping ground

43、water, 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 proteins and other materials in their tissues. As the plant dries, these resources take on first the

44、 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 plant's metabolism and protects its dried-out tissues. The plants also change shape, shrinking to minimize the surface area through

45、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 career, Farrant studied . recalcitrant seeds (执拗性种子) ," such as avo

46、cados, coffee and lychee. While tasty, such seeds are delicate--they cannot bud and grow if they dry out (as you may know if you've ever tried to grow a tree from an avocado pit). In the seed world, that makes them rare, because most seeds from flowering plants are quite robust. Most seed

47、s 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, Farrant beg

48、an investigating whether it might be possible to isolate the properties that make most seeds so resilient (迅速恢复活力旳) 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 d

49、ryness. 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 gen

50、es are regulated by a master set of genes,"Farrant says."We're 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."I'm try
