A cleaner stole an empty commuter train from a station and drove it to a suburb of Stockholm where it suddenly left its tracks and ran into an apartment building, officials have said.

The woman was seriously injured in the early－morning crash and was flown to a Stockholm hospital ，police spokesman Lars Bystrom said. No one else was injured.

He said the woman was arrested as a result of endangering the public.

Tomas Hedenius, a spokesman for the trainoperator Arriva，said the woman，who was born in 1990，stole the four－car train at a station outside Stockholm. She then drove it about a mile (1.6 km) to the end station on the railway line，where it jumped off the tracks, rushing for about 25 metres and crashed into a three－storey building. Photographs from the scene showed that the front car of the train buried deep into the structure.

“There were three families inside the apartment building, but no one was injured. At least not physically，” Hedenius said.

The aims of the woman, who worked for a company contracted to carry out cleaning for the train operator, were not immediately clear.

“We have only heard good things about her. We're looking into how this could happen, and why she did what she did，” Hedenius said. He said it was not clear how she got the keys to the train，but added that driving it was not that difficult.

“Generally speaking, that's possible even if you're not a train operator，” he said. “You can read about it on the Internet, or observe how others do it.”

文章大意：本文是一篇新闻报道。在斯德哥尔摩，一名清洁工人驾驶偷窃的火车冲入民宅，身受重伤。除此以外，没有人在此次事故中受伤。她这么做的具体原因正在调查中。

33．Why was the woman arrested by the police?

A．Because she stole a train and put the public in danger. B．Because she was not fit for cleaning and did some wrong. C．Because she wanted to hide the train in the apartment building. D．Because she didn't want to work for the train operator any longer. 答案：A 细节理解题。根据前两段可知，她是一名清洁工，偷开火车并造成事故，所以因妨碍公共安全被逮捕。其他三个选项都与文章内容不相符。

34．According to the passage，the woman cleaner ________. A．drove the train into the apartment building on purpose B．aimed at becoming a train operator by doing so

C．might learn to drive a train by observing train operators D．borrowed the keys to the train from the train operator

答案：C 推理判断题。根据第五段中的．.. carry out cleaning for the train operator...和最后一段可推断出，这位清洁工是为火车司机服务的，所以她学会开火车很可能是靠观察。A项“故意把火车开进公寓大楼”，B项“她这样做的目的是当火车司机”，文中均没有依据；D项文章中没有依据表明钥匙是从火车司机那里借的。
