【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。
