An explosion on Thursday killed one and injured 21 in a busy street in Tongren, Southwest China’s Guizhou Province.
The bomb was hidden in a rubbish bin in the city’s commercial hub（商业中心），where lots of shops and restaurants are concentrated.
The ear-splitting blast was heard around 12∶50 p.m.，said a local newspaper, citing witnesses. The power of the blast shattered（使粉碎）nearby shop windows and ripped the stainless（不生锈的）steel rubbish can to pieces.
One passer-by，identified（确认）only as Zhang，said she was shocked by the noise and saw a lot of pedestrians lying on the ground when she got to the scene.
Thirteen of the injured were taken to a local hospital after the explosion. A doctor there said five were in serious condition but already out of danger after emergency treatment. The others were just slightly hurt.
“The cause of the explosion is still unknown”, said an officer with the Tongren police, but refused to speculate as to the cause.

解析：说明本文讲述的是在贵州发生的爆炸事件，以及受伤处理等的处理情况。
【小题1】A 推理题。根据第四段最后2行A doctor there said five were in serious condition but already out of danger after emergency treatment. The others were just slightly hurt.说明不是所有的受伤的人都被送到了医院，有一些受轻伤的没有接受治疗。故A正确。
【小题2】C 推理题。根据文章第四段One passer-by，identified（确认）only as Zhang，said she was shocked by the noise and saw a lot of pedestrians lying on the ground when she got to the scene.说明本文的作者并不是亲身到现场的，只是采访别的一些在现场的人。故C正确。
【小题3】B 推理题。根据“The cause of the explosion is still unknown”, said an officer with the Tongren police, but refused to speculate as to the cause.说明爆炸的原因还不清楚，并且他拒绝猜测原因。故B正确。
【小题4】D 主旨大意题。根据文章第一段说明本文讲述的是在贵州发生的爆炸事件，故D正确。
