It is reported that in our country cities ________ heavy air pollution that is 30 percent above the national standard or higher should try to meet standards by 2030. A．suffering B．suffer C．suffered D．are suffering

Answer 1

A

试题分析：考查现在分词做定语：句意：据报道我们国家遭遇严重的空气污染在国家标准以上30%的城市到2030年要努力达到标准。这里是定语修饰cities，cities和suffer heavy air pollution是主动关系，用现在分词做定语，选A。 点评：当分词做定语的时候，如果构成分词的动词与名词构成主动关系，就使用现在分词做定语；当二者构成被动关系，使用过去分词做定语。单独的一个分词做定语要放在名词的前面，分词短语做定语要放在分词的后面。
