16、是介绍太空种植植物的好处, 即宇航员也喜欢在他们的干粮中有新鲜的果蔬食物。故F项正确。上文介绍了太空种植的好处, 结合下文可知, 太空种植有一定的困难, 据此可知, 空处承上启下, 与上文形成转折关系。故B项正确。根据上文可知, 在失重的情况下, 植物的根和叶不知道如何生长, 水分也不容易从根部传到叶子上, 而空后一句介绍了关于土壤的解决方法, 据此可推知, 空处应是介绍解决上述问题的方法, 故E项正在研制专门的容器去帮助植物正确地生长 符合语境。根据空前一句可知, 科学家们正在寻找各种让植物少使用水和光, 在太空快速生长, 而且可以抵抗病害的方法, 且下文又提到改良后的植物对地球的影响, 据
17、此可推知, 空处应是说这些方法可以在地球上运用以带来改善。故C项正确。 四、答案：ability which made a but is based to encourage It especially largest解析：考查名词。分析句子结构并由空前的its可知, 空处作宾语, 应用名词形式, 所以填ability。 考查定语从句。_ has improved the quality of peoples lives作定语, 修饰Chinas high-tech innovation, 因空前有逗号隔开, 所以空处引导非限制性定语从句, 并在从句中作主语, 故填which。考查非谓语动词。
18、make与其逻辑主语a survey之间是被动关系, 所以用动词-ed形式作定语, 故填made。考查冠词。此处泛指一名大学生, 且university的发音以半元音音素开头, 所以填不定冠词a。考查连词。由语境可知, 空处前后为转折关系, 将自行车本身与共享单车的运行模式进行比较, 故应填but。考查主谓一致、时态和语态。主语为the operating mode of bike-sharing, 表示单数概念, 且此处表示客观事实, 所以用一般现在时; 因the operating mode of bike-sharing与base on之间是被动关系, 应用被动语态, 故填is based。考查动词不定式。分析句子结构可知, 此处应用动词不定式作目的状语, 所以填to encourage。考查形式主语。that China is innovating and no longer copying Western ideas是句子真正的主语, 句子主语较长, 为避免句子头重脚轻, 这里需要一个形式主语, 所以填It。考查副词。空处作状语, 应用副词, 所以填especially。考查形容词的最高级。由空前的the以及空后的in the world可知, 空处应用最高级形式, 所以填largest。
