Question

3．There is a change in the air at the tea factory in Thika，Kenya．It is free of the dark smoke that rises from the boilers（锅炉） of Kenya's other tea factories．
Makomboki Company has begun to use a less costly and more environmentally friendly fuel．Instead of burning wood，the tea maker is burning briquettes（煤球） made of animal material waste and something else，The Kenya Tea Development Authority supervises（治理） Kenya's 66 tea factories．Makomboki is the only one that does not use firewood in tea production．The factory is deep in central Kenya's hilly and fertile tea-growing Muranga County．The employees feed the factory's boilers with briquettes of plants and rice husks-the dry outer covering of the seeds
-mixed with sawdust（锯屑）．John Gitau，manager at the factory，expressed excitement about their change in fuels．They haven't used a single cubic meter of firewood in the last six months．
In 2010，the International Trade Center started a training project．It aimed to teach Kenyan tea makers new production methods to help limit the release of climate change gases．Since then，Makomboki Company has increased its use of optional fuels and stopped depending on firewood．Taylors of Harrogate is a Makomboki customer．The British tea and coffee company helped the Kenyan factory change fuels．It connected Makomboki with the Living Earth Foundation．The non-governmental group donated the machines to make the briquettes．The husks for the briquettes come from otherfactories within Muranga and Kiambu counties．The sawdust comes from factories near the tea factory．
John Gitau said it takes the factory six months to produce about 2.5 million kilograms of tea．During that time，their boilers would use up to 10，000 cubic meters of wood-or about 30，000 trees worth．Furthermore，the factory used to spend 542，000ayearonfirewood．Now，theintroductionofbriquetteshascuttheenergybillto295，600．
John Gitau said representatives from other factories have visited Malomboli to learn more about the optional fuel．He hopes more factories will follow his company's lead in 2016．

Answer 1

分析 文章介绍了在in Thika，Kenya的一些茶厂改变了用燃料的方式，从原来的烧木材到现在的煤炭，节约了成本也保护了环境．

解答 D D A A
28．D 细节题．在第二段的第一句话Makomboki Company has begun to use a less costly and more environmentally friendly fuel告诉我们开始使用一种更加低成本但更环保的燃料，所以目的是为了保护环境．
29．D 细节题．The factory is deep in central Kenya's hilly and fertile tea-growing Muranga County该公司是唯一一家地处Muranga county中心的茶厂，所以其地理位置决定了它使用新型燃料的必要性．
30．A推理题．在第三段提到其他工厂提供煤球，还有sawdust都是对新型燃料提供加工过程．
31．A细节题．文章并没有提到在该地区只有66 tea factories 所以A是错误的；根据文章最后一段During that time，their boilers would use up to 10，000 cubic meters of wood-or about 30，000 trees worth．Furthermore，the factory used to spend 542，000ayearonfirewood．Now，theintroductionofbriquetteshascuttheenergybillto295，600．
可知，John Gitau 高度赞扬了新型燃料，所以BC是正确的．
