体裁：说明文 题材：农业科技 主题：用海水种植水稻
【语篇解读】 中国的研究人员在迪拜已成功种植并收获了一种用海水种植的水稻。
1．答案与解析：successfully 考查副词。修饰动词用副词，根据空后的“grown and harvested”可知，此处应用副词successfully。
2．答案与解析：allows 考查时态和主谓一致。根据语境可知，此处叙述一般的情况，故应用一般现在时；空前的“which”引导的是定语从句，which在从句中作主语，指代先行词a strain，为第三人称单数，故填allows。
3．答案与解析：led 考查非谓语动词。分析句子结构可知，动词lead和其逻辑主语A team of scientists之间为动宾关系，故此处应用过去分词短语作后置定语。
4．答案与解析：global 考查形容词。根据空前的“the”和空后的“average”可知，此处应用形容词global作名词average的定语。
5．答案与解析：planned 考查动词的时态。根据本句中的“later last year”可知，此处应用一般过去时，表示发生在过去的动作。
6．答案与解析：agreement 考查词形转换。根据语境以及空前的“an”可知，此处应用agree的名词形式agreement。
7．答案与解析：where 考查定语从句。分析句子结构可知，空处引导定语从句，修饰先行词countries，关系词在从句中作地点状语，所以此处应用where来引导该从句。
8．答案与解析：to develop 考查非谓语动词。根据语境可知，过去四十年，中国一直致力于开发抗盐的水稻，此处表示目的，故填to develop。
9．答案与解析：it 考查代词。分析句子结构可知，此处应用it作形式主语，how引导的从句作真正的主语。
10．答案与解析：for 考查介词。根据语境可知，此处表示稀释海水是为了大规模种植水稻，故用介词for“为了”。
