Free use of languages was something he had a personal interest in addressing: he grew up in Guatemala, where he was surrounded by people all trying to learn English, half of whom were failing to do so and a lot of whom could not afford it.”可知Von Ahn说,他创建DuoLingo是因为他想为人们找到一种免费学习语言的方法。他想让人们能自由地使用语言。他在危地马拉长大,周围都是想学英语的人,其中一半人没能做到,还有很多人负担不起。由此可推知,作者在第三段提到Von Ahn是为了解释他开发这个软件的原因。故选B。 3.C　推理判断题。根据第四段“One of the big changes caused by tech is the change in language learners. Languages have long been connected with the rich people, but now people from less rich backgrounds are finding affordable ways to learn.”可知,家境不太富裕的人正在找负担得起的学习方式,DuoLingo 恰恰提供了这种方式。由此可推知,学习者可以以低成本的方式学习。故选C。 4.D　主旨大意题。通读全文并根据文章第一句话“‘There are more people actively learning a language through DuoLingo than in the entire US public school system,’ says Luis von Ahn, the founder of the free language learning app.”可知,本文主要讲述了Luis von Ahn开发了DuoLingo 来帮助人们学习语言。因此,D项“用DuoLingo 掌握一门语言”适合做本文标题。故选D。 Ⅵ.【文章大意】 本文是一篇说明文。文章介绍了如何将绿色科技添加到家中。 1.G　根据前文“Green tech involves combining technology and science to create environmentally-friendly products. The idea is that by using products and services in the home to reduce energy consumption, waste, o ... ...
