本周PTE国内考场SWT原题解析 - 非洲黑土地,IPENGLISH黄老师微信公众号文章

各位学霸们好，黄老师来分享一道本周国内考场出现过的一道PTE写作SWT真题 - African Dark Earths 非洲黑土地（来源：雅培PTE高频机经满分答案 SWT#43）

思路分析

该篇文章围绕着African Dark Earths非洲黑土地展开，且信息较为杂乱，同学们如果想得到一个高分的内容分需要把文章不同句子里的信息碎片合并到答案中，而不是像简单题目那样文章找3-4个完整的句子，然后用从句合并。

另外，黄老师想再强调一下，千万不要在SWT中无脑用while / and合并文章答案，因为答案必须符合原文逻辑关系才能得分，所以无脑while / and模版只能表示并列关系，这就是在碰运气了：碰考试的信息是并列关系，370刀去碰一次运气，划不来啊！

那么，带着上面的思路，同学们可以参考黄老师的答案哦：

43. African Dark Earths

A global study by researchers has for the first-time identified and analyzed rich fertile soils found in Liberia and Ghana. They discovered that the ancient West African method of adding charcoal and kitchen waste to highly weathered, nutrient poor tropical soils can transform the land into enduringly fertile, carbon-rich black soils which the researchers dub 'African Dark Earths'.

Similar soils created by Amazonian people in pre-Columbian eras have recently been discovered in South America, but the techniques people used to create these soils are unknown. Moreover, the activities which led to the creation of these anthropogenic soils were largely disrupted after the European conquest.

Encouragingly researchers in the West Africa study were able to live within communities as they created their fertile soils. This enabled them to learn the techniques used by the women from the indigenous communities who disposed of ash, bones and other organic waste to create the African Dark Earths.

参考答案：

A farming technique practiced for centuries by villagers in West Africa, which converts nutrient-poor rainforest soil into fertile farmland, could be the answer to mitigating climate change and revolutionizing farming across Africa, andafter researchers had found and named rich fertile soils found in Africa ‘the African Dark Earths’ , they tried to learn the unknown techniques used by the indigenous communities to create the African Dark Earths.

秒懂逻辑：（该题信息点较为杂乱，请注意整合）

非洲有一种农业技术，能够把贫瘠土地转化为富饶的土壤，研究发现且命名这些土地为‘非洲黑土地’，而且正在研究这种未知的创造黑土地的技术。
