US Signs Global Tobacco Treaty
1 The United States has taken the first step toward approving a global tobacco treaty that promises to help control the deadly effects of tobacco use throughout the world. Health and Human Services Secretary Tommy Thompson signed the Framework Convention on Tobacco Control (FCTC) this week at the United Nations. (46)
2 The FCTC was developed by the World Health Organization and approved by members of the World Health Assembly，including the United States，last year. (47)
3 For instance, cigarettes sold in those countries would have to have health warnings on at least 30% of the front and back of every pack. (48)It also requires bans on tobacco advertising, though there are some exceptions for countries like the United States, where the Constitution prohibits such an outright ban.
4 (49) The World Health Organization estimates that tobacco use kills nearly 5 million people worldwide every year. In the US alone, about 440,000 people die each year from tobacco-related illnesses; about one-third of all cancers in the US are caused by tobacco use. If current trends continue, WHO estimates, by 2025 tobacco will kill 10 million people each year.
5 The treaty must be ratified by at least 40 countries before it can take effect. (50)
A Tobacco stocks also perked up as investions discouried fears of from the US.
B So far，109 countries have signed it, and 12 have ratified it.
C The impact of the treaty could be huge.
D Countries that ratify it would be required to enact strict tobacco control policies.
E The treaty calls for higher tobacco taxes, restrictions on smoking in public places, and more promotion of tobacco prevention and cessation programs.
F The Senate must still approve the treaty before the US can implement its provisions.
参考答案：FDECB

一、真题原文
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 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 to medicine, and, as the demand for sugar grew, the industry became larger and more profitable. （47） Many crops withered 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 Barbados looked for ways to make the commercial species stronger and more able to resist disease. They experimented with breeding programmes, mixing genes from the wild species of sugar cane, which tends to be tougher, with 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 incredibly profitable for the industry.
（49） Brazil, which produces one quarter of the worlds sugar, has coordinated an international project under Professor Paulo Arrudo of the Universidade Estadual 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 function 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. Scientists believe 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 DHont 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 canes genetic code.
E. The majority of the worlds sugar now comes from this particular commercial species.
F. Unfortunately, however, the plant started to become weaker and more prone to disease.
二、答案与解析
46. E。解析：前一句提到“Over time, sugar cane became a highly valuable commercial plant, grown throughout the world.（随着时间的推移，甘蔗成为一种极具价值的商业作物，在世界各地种植）”，E选项“The majority of the worlds sugar now comes from this particular commercial species.（现在世界上大部分的糖都来自这种特殊的商业品种）”进一步说明了甘蔗作为商业作物的重要性，在逻辑上承接了上一句，符合语境。
47. F。解析：空后句子“Many crops withered and died, despite growers attempts to save them, and there were fears that the health of the plant would continue to deteriorate.（尽管种植者试图挽救，但许多作物枯萎死亡，人们担心这种植物的健康状况会继续恶化）”描述了甘蔗出现的问题，F选项“Unfortunately, however, the plant started to become weaker and more prone to disease.（然而，不幸的是，这种植物开始变得更脆弱，更容易生病）”与后文内容相呼应，能够很好地引出下文所讲的甘蔗遇到的危机。
48. A。解析：前文“They experimented with breeding programmes, mixing genes from the wild species of sugar cane, which tends to be tougher, with genes from the more delicate, commercial type.（他们进行了育种计划，将更坚韧的野生甘蔗品种的基因与更娇弱的商业品种的基因混合）”讲述了科学家的实验，A选项“Eventually, a commercial plant was developed which was 5 percent sweeter than before, but also much stronger and less likely to die from disease.（最终，培育出了一种商业甘蔗品种，它比以前甜5%，而且更健壮，更不容易死于疾病）”是对实验结果的描述，符合文章的逻辑发展。
49. D。解析：后文“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.（专家团队与他合作，以发现更多关于植物基因结构的哪些部分对糖的生产及其整体健康很重要）”表明科学家在研究甘蔗的.基因，D选项“Since the 1960s, scientists have been analyzing the mysteries of the sugar canes genetic code.（自20世纪60年代以来，科学家一直在分析甘蔗基因密码的奥秘）”能够开启下文关于基因研究的内容。
50. B。解析：后文“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.（这个基因特别令人兴奋，因为它使植物对锈病有抵抗力，锈病可能起源于印度，但现在能够感染世界各地的甘蔗）”提到了一个基因，B选项“One major gene has been identified by Dr. Angelique DHont and her team in Montpelier, France.（法国蒙比利埃的Angelique DHont博士和她的团队已经确定了一个主要基因）”引出了这个基因，使前后文衔接紧密。
