The Tough Grass that Sweetens Our Lives
Sugar cane was once a wild grass that grew in New Guinea and was used by local people for roofing their houses and fencing their gardens. Gradually a different variety evolved which contained sucrose (蔗糖) and was chewed on for its sweet taste. Over time, sugar cane became a highly valuable commercial plant, grown throughout the world. __________ (46)
Sugar became a vital ingredient in all kinds of things, from confectionery (糖果點(diǎn)心) to medicine,and, as the demand for sugar grew, the industry became larger and more profitable. __________(47)
Many crops withered (枯萎) and died, despite growers' attempts to save them, and there were fears that the health of the plant would continue to deteriorate.
In the 1960s, scientists working in Barbodos looked for ways to make the commercial species stronger and more able to resist disease. They experimented with breeding programmes, mixing genes from the more delicate, commercial type.__________(48) This sugar cane is not yet ready to be sold commercially, but when this happens, it is expected to be incredible profitable for the industry.
__________(49) Brazil, which produces one quarter of the world's sugar, has coordinated an international project under Professor Paulo Arrudo of the Universidade Estaudual de Campinas in Sao Paulo. Teams of experts have worked with him to discover more about which parts of the genetic structure of the plant are important for the production of sugar and its overall health.
Despite all the research, however, we still do not fully understand how the genes in sugar cane__________ (50) This gene is particularly exciting because it makes the plant resistant to rust, a disease which probably originated in India, but is now capable of infecting sugar cane across the world. Scientist believes they will eventually be able to grow a plant which cannot be destroyed by rust.
A. Eventually, a commercial plant was developed which was 5 percent sweeter than before,but also much stronger and less likely to die from disease.
B. One major gene has been identified by Dr Angelique D'Hont and her team in Montpelier,France.
C. Sugar cane is now much more vigorous and the supply of sugar is therefore more
guaranteed.
D. Since the 1960s, scientists have been analyzing the mysteries of the sugar cane's genetic code.
E. The majority of the world's sugar now comes from this particular commercial species.
F. Unfortunately, however, the plant started to become weaker and more prone to disease.
答案與解析
46.E。空格前一句甘蔗成了一種極具價(jià)值的商業(yè)作物，在全世界種植。空白處應(yīng)繼續(xù)談?wù)撈鋬r(jià)值，故E選項(xiàng)(現(xiàn)在世界上大部分糖都是產(chǎn)自這個(gè)特殊的商業(yè)作物)符合文意。
47.F。空格前提到對(duì)糖的需求增加，這個(gè)行業(yè)開(kāi)始獲利，而空格后提到植物枯萎并死掉。前后具有轉(zhuǎn)折關(guān)系，所有選項(xiàng)中只有F含有轉(zhuǎn)折詞however，故F(然而不幸的是這種植物開(kāi)始變?nèi)�，容易得�?是正確答案。
48.A�？崭袂疤岬搅丝茖W(xué)家進(jìn)行不同植物基因混合的實(shí)驗(yàn)來(lái)培育新品種，空格后提到現(xiàn)在這種甘蔗植物還不準(zhǔn)備用做商業(yè)用途。由此可知，空白處講的應(yīng)該是關(guān)于新的甘蔗品種，
故A(最終，一種新的商業(yè)甘蔗被培養(yǎng)出來(lái)，比之前的甜度增加5%，而且比之前的作物要更強(qiáng)壯，發(fā)病的可能性更小)是正確答案。
49.D�？崭窈罅信e了巴西的例子，指出科學(xué)家試圖發(fā)現(xiàn)更多的影響含糖量和產(chǎn)量的.基因結(jié)構(gòu)，故D項(xiàng)(自20世紀(jì)60年代起，科學(xué)家一直在研究甘蔗基因代碼的秘密)是正確答案。
50.B�？崭袂疤岬窖芯空邆�?nèi)匀粺o(wú)法完全了解甘蔗的基因，空格后提到這個(gè)基因尤其令人興奮，其中的this gene應(yīng)該指代空白處提到的某個(gè)基因，故8選項(xiàng)(一個(gè)主要的基因已經(jīng)由AngelliqueD’Hont博士及其團(tuán)隊(duì)鑒別出來(lái)了)符合文意。
