Who________ for the pollution of our earth?A.should blameB.is to blameC.is blameD.is to be blame

B解析试题分析：blame用作及物动词时,通常用于下面三个句型:（1）. blame sb. for sth. /doing sth. 为某事责备某人/责备某人做了某事。如:Many children are afraid of being blamed for making mistakes in speaking English. 许多孩子害怕讲英语时犯错误而受责备。（2）. blame sth. on sb. 把某事归咎于某人。如:The police blamed the traffic accident on Jack's careless driving. 警察把那起交通事故归咎于杰克的粗心驾驶。（3）. be to blame (for)应(为……)承担责任;该(为……)受责备。[注意]此处不能用被动语态。如:The children were not to blame for the accident. 那次事故怪不着孩子们。He is more to blame than you. 是他更应受责备,而不是你。Who is to blame for starting the fire? 这场火灾该由谁负责?I am in no way to blame. 决不该责备我。故选B。考点：考查固定短语的用法。点评：本题难度适中。对于be to blame的用法考生要牢记，同时分清blame的另外的两种用法，需放在一定的语境里去理解。即学即练：Judging from the evidence on spot, the truck driver______for the accident. A. is to blame; B. is blamed; C. blames; D. will be blamed解析：A 句意：从现场的证据来看，卡车司机是这次交通事故的责任人。
