6、rge sb. to do 敦促某人做。 3.creatures考查名词所有格。the creatures environment 指“这种生物的环境”，即 考拉的生存环境。 4.to考查介词。表示“减少到”，为 drop to。 5.biggest考查比较等级。The biggest decrease减少最多的。 6.where考查定语从句。因先行词为 New South Wales，指地点，且从句不缺主语或 宾语，所以用 where 引导定语从句，并在从句中作状语。 7.loss考查词类转换。动词 lose 转换为名词 loss，在句中作主语。 8.were destroyed考查被动语态。因林地是“被破坏”的，用被动语态。句中有具体 的过去时间 2019，用一般过去时。所以填一般过去时被动语态。 9.has考查时态和主谓一致。因主语的中心词是 Land clearing，是单数，所以在现在 完成时中用 has done。句意：房地产开发商和筑路商的土地清理也破坏了考拉的环境。 10.working考查非谓语。keep doing 继续做。
