【正文】 ict itself to the past. Rather, the book takes the story of perhaps the most popular crop of all time and brings it disturbingly into the present day. Walvin begins his research where most of us begin our relationship with the stuff: the sweet shops of childhood memory. If sugar is a guilty pleasure then it is one with which almost every one of us is drunk on a daily basis. The unstoppable march of sugar raises the question: why? After all, sugar cane(甘蔗 )is difficult to grow and the processes of refinement and clarification required to produce eatable sugar are timeconsuming and expensive. Yet, as Walvin explains, sugar has one enormous temptation: it satisfies our seemingly born desire for sweet tastes, but the satisfaction that sugar provides es at a terrible cost, both to those who produce it and those who consume it. Sugar changed world history more profoundly than any other crop. It fuelled the Atlantic slave trade and the African wars. We’re familiar with the story of how millions of enslaved Africans were transported to the Caribbean, the US and Brazil, but the growing global demand for sugar also led to the migrations of other groups. The profitability of sugar production also inspired American producers to ship thousands of poor Indians from their homeland to the Caribbean, South America and Fiji as well as Japanese peasants to plantations in Hawaii. The story of sugar, then, is not just one of changing diets and expanding waistlines, but also one of mass migrations—both forced and voluntary, both familiar and unfamiliar. Sugar’s story in the 20th and 21st centuries can only be told with reference to the development of American agricultural businesses and the giant food corporations, most notably the CocaCola Company. The modern antisugar movement is demanding better labelling and the reduction of sugar in foods and drinks targeted at children. The sugar industry stands today where the tobacco corporations stood in the 1960s, accused of knowingly contributing to a global health crisis and obesity. This is just the latest moral crisis faced by the food giants of the sweet stuff. 58. What can we learn from Paragraph 1? A. Walvin’s book focuses only on sugar in the past. B.

C The most eyecatching part of the government’s recent airquality strategy is to ban sales of new petrol and diesel cars by 2040. The reason behind the government’s strategy is poor air quality, which is thought to be linked to about 40,000 premature deaths a year. Client Earth, the campaign group leading the call for reform, has described the ban as “not enough”. It emphasises that clean air zones and sustainable transport infrastructures both work, and can be implemented more quickly. Even so, some argue that the target is too soon. The motor industry, however, does not argue that the cars won’t be ready in time. This is unsurprising, given that Tesla already has an allelectric model, most manufacturers have at least one hybrid (混動汽車 )on sale. The voices of disagreement offer three main arguments: electric vehicles don’t reduce greenhouse gas emissions。 21.
