问答题我最大的爱好是沉思默想。我可以一个人长时间地独处而感到愉快。独享欢乐是一种愉快，独自忧伤也是一种愉快。孤独的时候，精神不会是一片纯粹的空白，它仍然是一个丰富多彩的世界。情绪上的大欢乐和大悲痛往往都是在孤独中产生的。孤独中，思维可以不依照逻辑进行。孤独更多地产生人生的诗情——激昂的和伤感的。孤独可以使人的思想向更遥远更深邃的地方伸展，也能使你对自己或环境作更透彻的认识和检讨。

问答题One day in September, 2001 ,a 7-month-old son of an ABC producer in Manhattan spent time at the network offices. He developed a rash, and was hospitalized with an unknown ailment soon after the visit. He was later diagnosed with cutaneous anthrax. This was the beginning of the anthrax scare created by terrorists throughout the USA and the rest of the world. The forced closure of Capitol Hill, the building that is home to both houses of the US Congress, has confirmed perhaps the worst fears of US Congress, has confirmed perhaps the worst fears of US officials; that their country now faces a bioterrorist attack. In all, 44 cases of anthrax attacks have been detected so far, including one death. The majority of cases in the US have surfaced at institutions of influence or prominence. Apart from the mail sent to the senators, letters laced with the bacteria were sent to the offices of the ABC and NBC television networks and The New York Times. Meanwhile, police in Japan, Canada, Europe, Latin America, Africa and Australia have also been investigating suspicious substances either sent through the mail or left at public places -- one case of anthrax contamination has surfaced outside the US, in Kenya.
