题目内容
11.Our planet,Earth,is becoming more and more crowded andpolluted.(pollute )分析 我们的行星--地球,正变得越来越拥挤和遭受污染(肮脏).
解答 答案:polluted
联系语境,根据关键词becoming,可知它是一个系动词,其后应该跟形容词形式;结合给出的提示词为动词pollute,"污染",结合语境,地球应该是被人污染的,含有被动的意味,所以此处应该用pollute的过去分词形式为polluted,意为"被污染的",表被动,相当于形容词的功能.故填写polluted.
点评 此题考查过去分词的特殊用法.做题时结合句意仔细揣摩出所需填入词的意义,联系过去分词的用法作答.
