Unit 2 The United Kingdom李仕才一、阅读理解ASeveral companies in Europe, the US and Asia have decided to change one of the processes of making chocolate and no longer roast the cacao beans. They insist that growers in Africa and South America leave them outdoors to dry naturally instead. The resulting product is called “raw” chocolate. Producers claim that avoiding exposure to oven temperatures allows the preservation of nutrients such as iron, zinc, copper and vitamin C．Its also claimed that uncooked cacao contains higher levels of antioxidants(抗氧化物) than roasted cacao used in most chocolate. “Over the last 10 years, consumers have become more involved in their food and drink，” says Kris McGowan, who runs the Raw Chocolate Company. “They care a lot more about its healthy qualities and chocolate is no exception.” But Martin Schweizer, professor of biochemistry at HeriotWatt University, urges caution on describing raw chocolate as a super food until more research is carried out. “We have to look at this in more depth. The research is at a fairly early stage.”There are concerns that not heating them to about 150 ℃ could mean an increase in bacteria. However, producers insist that, as no animal products are involved, there is no greater risk than when dealing with vegetables such as carrots or lettuces. Jennifer Earle, a writer on chocolate, is unconvinced by it on taste grounds. “Its the quality of the cacao that makes a difference, not whether the chocolate is ‘raw’ or not，” she says. “And if youre talking about health, Id rather eat some topquality ordinary chocolate and have a plate of vegetables afterwards.”【文章大意】　本文是一篇说明文。

许多生产商在制作巧克力时不再对可可豆进行加热烘干，并宣称这样做可以保护可可豆中的营养物质，但是一些研究人员对此有不同的看法长难句分析】However, producers insist that, as no animal products are involved, there is no greater risk than when dealing with vegetables such as carrots or lettuces.(第五段第二句)分析：本句是一个主从复合句that引导的是宾语从句，作insist的宾语；在宾语从句中含有as引导的原因状语从句译文：然而，生产者坚持认为，因为没有涉及动物制品，所以不加热到150 ℃时的风险与处理胡萝卜和生菜这类蔬菜时存在的风险一样小1．Chocolate bean growers in Africa ________.A．dry the beans outdoors naturallyB．roast the beans at a low temperatureC．cook the beans in pots instead of in ovensD．store the beans with uncooked vegetables答案与解析：A　考查细节理解。

The research is at a fairly early stage.”(第四段第二、三句)译文：“我们还需要对此做更深入的研究这个研究还处于一个相当初级的阶段解题思路】根据关键句可知，对生巧克力的研究还处于初级阶段，由此可推断，针对生巧克力的研究还没有做BIt has always been thought that alcohol causes people to put on weight because it contains a lot of sugar, but new research suggests a glass a day cold form part of a diet. Looking at past studies they found that, while heavy drinkers do put on weight; those who drink in moderation can actually lose weight. A spokesman for the research team at Navarro University in Spain says, ＂Light to moderate alcohol intake, especially of wine, may be more likely to protect against, rather than promote, weight gain.＂ The International Scientific Forum on Alcohol research reviewed the findings and agreed with most of the conclusions, particularly that data do not clearly indicate if moderate drinking increases weight. Boston University’s Dr. Harvey Finkel found that the biologic mechanisms(生物学机制) relating alcohol to changes in body weight are not properly understood. His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes(糖尿病), which relate to increasing obesity. Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers. The group says alcohol p。
