答案以及解析
一、单选题
1.答案：D
解析：考查数词的用法。句意：这里的环境变得越来越好。成千上万的鸟儿正在回来。当 hundred、 thousand前有具体的数字时，表示确数， hundred、 thousand后不加-s，其后也不用of；当 hundred、 thousand前没有具体数字时，表示概数， hundred、 thousand后既要加-s，也要加of。故选D。
2.答案：A
解析：句意：污染的空气和水可以杀死植物、动物甚至人。can能，可以；can't不能，不会，不可能；should应该；shouldn't不应该；根据预测句意"污染的空气和水可以杀死植物、动物甚至人"和语法可知，要填"可以"，其它选项语意不通，也不符合语法。故选：A。
