13、ting the environment)。B 符合新闻内容。回收电子垃圾并不只是为了获取利润，故 A错误。C“提高电子技术”和 D“出口丢弃的电子产品”均是利用新闻原词作干扰，不是该中心的目的。A.They pose great threat to peoples health. B.They are bad for economic development.C.They insert negative effects on the environment.D.They seldom get recycled in developing countries.解析：解析：新闻末尾部分提到，联合

14、国报告称全世界数百万吨的电子垃圾最终流往发展中国家，有毒材料如铅和汞等对这些国家构成了严重的健康威胁。这种行为无视禁止出口这些废弃电子产品的国际协议。可推测国际协议禁止出口废弃电子产品的原因是电子垃圾严重威胁人类健康，A 正确。B“对经济发展有负面影响”完全没有在新闻中提到。C“电子垃圾对环境有负面影响”这一说法是正确的，但答非所问，并非新闻中提到的原因。D“在发展中国家很少得到回收”无法从新闻内容推断出来。A.Over 3,700.

16、Vandoornick表示很难找到幸存的家庭，A“可以找到更多幸存的家庭”错误。B“新中心能够帮助越来越多的孤儿”是 Doris的希望。新闻随后提到 Doris对孤儿的未来充满担心，故 C不对。A.The African green revolution forum.B.The speed and severity of climate change.

17、and severity of climate change)可能会对非洲小农户造成重大破坏，B 完全复现原文，为答案。C“大多数牲畜死亡”出现在新闻最后部分，是气候变化对非洲农户造成的后果。A、D 都有在新闻中提到，但这两项答非所问，与问题无关。A.Small-scale farmers are the major support for African agriculture.
