Answer 1

【答案】has后加上never/not；had→have；for→with；are→is；certain→certainly；and→than；considered后的it去掉；site→sites；a→an；you→they
【解析】本文讲述的是黑龙江省挠力河自然公园发现东方白鹳的情况。
①has后加上never/not 考查否定形式。根据上下文应该是还没有被发现，故加上never/not。
②had→have 考查时态。根据上下文应用现在完成时，故将have改为has。
③for→with 考查介词。此处是birds本身带有，应用with。
④are→is 考查主谓一致。该句的主语是the population，故are改为is。
⑤certain→certainly 考查副词。根据certainly后的系动词is判断应用副词形式。故改为certainly。
⑥and→than 考查比较句型。根据前文的better和下文的before判断修改，故and改为than
⑦considered后的it去掉 考查代词。此句是被动语态，it与主语重复，故去掉。
⑧site→sites 考查名词。根据前文的one of判断应该用名词的复数形式。故site改为sites。
⑨a→an 考查冠词。根据词组keep an eye on判断。故a改为an。
⑩you→they 考查代词。根据前文birds判断应用they。
