问题     Smallholder farmers resettled to rainforests by the Brazilian government have played an unrecognised role in deforestation there—something researchers worry is continuing unabated.
    Brazilian president Dilma Rousseff boasted last month that her government had reduced annual forest loss by two-thirds in the past decade, and would end it altogether by 2030. Yet while overall deforestation has fallen, Brazilian researchers reveal that the country’s officials are still organising the large-scale migration of poor farmers who have been wrecking the rainforest. While the government has clamped down on illegal forest clearance by big landowners running cattle ranches and soya farms, its social resettlement schemes to allocate land to the rural poor are doing more damage than previously estimated.
    The researchers looked at four decades of satellite images of forest cover around the homes of more than a million migrants in some 1900 Amazon settlements established by the government’s National Institute for Colonization and Agrarian Reform(INCRA)since 1970. They found "irrefutable evidence of rapid deforestation" after the settlers arrived. Within the settlement areas, which cover roughly the size of the UK, half the trees have been lost, says a Brazilian researcher.
    The resettlement areas cover 5. 3 percent of the Brazilian Amazon, but have been responsible for 13.5 percent of deforestation since 1970. "Agrarian settlements have been widely hailed as a socially responsible strategy to allocate land to the rural poor," says Schneider. "But INCRA’s policy of giving settlers just a few hectares forces them to convert every inch of land to agriculture. Our research shows that the result is severe deforestation at the taxpayer’s expense. "
    INCRA officials, who were unavailable for comment ahead of the paper’s publication, have often argued that deforestation occurs before settlers arrive. But Schneider says the findings refute this. Charles Clement of Brazil’s National Institute of Amazonian Research in Manaus, says: " INCRA abandons the settlers as soon as they arrive. They seldom get guidance about how to manage Amazonian forests , so they try to practise the farming methods they grew up with. But they soon discover that the soils cannot sustain these methods, which leads them to carry out more deforestation. "
    Overall, Amazon deforestation is much reduced from a decade ago, says Schneider. But he worries that the deforestation from resettled smallholder farmers will go on unabated. Even though INCRA launched a green settlement programme aimed at curbing illegal deforestation by settlers in 2012, its effectiveness is yet to be assessed, Schneider says. To really address the problem, he adds, the government should stop moving people into forested areas. One solution would be to switch settlement schemes from existing forests to former forests that are now degraded pastures.
According to the author, deforestation would end if the government of Brazil______.
选项 A、stops relocating small holder farmers to the Amazon rainforests
B、offers straining of scientific farming methods to the resettled farmers
C、permits settlers to turn rainforest into farmland in their own way
D、relocates the settlers to degraded pastures instead of forests
答案D
解析 推断题。根据题干定位到最后一段。问题为“作者认为巴西政府通过何种方式可以结束滥伐森林的现象”。由该段最后一句One solution would be to switch settlement schemesfrom existing forests to former forests that are now degraded pastures可知“将移居者安置在退化的草场而不是森林地区，是一种解决办法”，所以[D]选项正确。[A]选项中的Amazon rainfore—sts将原文中“森林”的范围缩小了，可排除。[B]选项原文并未提及，可排除，同理可排除[C]选项。
