But spending money on the city's basic transport system is perfectly possible, and indeed essential. That kind of preventive investment always seems too expensive at first, but only until you're suddenly faced with the much higher repair bills New York is dealing with today. And as oceans continue to warm and sea levels continue to rise, the problem is only getting worse. In the past 20 years, Hurricanes Andrew, Floyd, Katrina, Rita, Dean, Irene, Isaac and others have tried to remind us of that simple truth. Now Hurricane Sandy is adding her voice. One of these days, we might actually listen.

　　1．What can we infer from Paragraph 1?

　　A．The subway system may start running soon.

　　B．The whole subway system is flooded with corrosive salt water.

　　C．It is difficult to repair the New York subway system.

　　D．The MTA doesn't know how to clean the subway system.

　　解析：选C　推理判断题。根据第一段中的“The Metropolitan Transit Authority (MTA) ...Charles Seaton.”可知，纽约交通运输管理局也不知道地铁何时能恢复运营。Seaton的言外之意是，他不知道地铁系统何时恢复正常，由此可推断，地铁系统的修复工作难度很大。C项正确。

　　2．Before Hurricane Sandy, New York's subway has long been troubled by ________.

　　A．corrosive salt water

　　B．water seepage
