请问911事件的英文怎么说?如果卸载文章里面,需要加冠词吗?

nine eleven用这个,没有 the The September 11,2001 attacks (often referred to as 9/11—pronounced "nine eleven") consisted of a series of coordinated terrorist[1] suicide attacks by Islamic extremists on the United States on September 11,2001。The victims were predominantly civilians。On the morning of September 11,2001,nineteen terrorists[2] affiliated with al-Qaeda[3] hijacked four commercial passenger jet airliners。Each team of hijackers included a trained pilot。The hijackers crashed two of the airliners (United Airlines Flight 175 and American Airlines Flight 11) into the World Trade Center in New York City,one plane into each tower (1 WTC and 2 WTC),resulting in the collapse of both buildings soon afterward。A nearby church and the rest of the World Trade Center complex's 7 buildings were also destroyed or damaged beyond repair。A third airliner (American Airlines Flight 77) was crashed into the Pentagon in Arlington County,Virginia。Passengers and members of the flight crew on the fourth aircraft (United Airlines Flight 93) attempted to retake control of their plane from the hijackers; that plane crashed into a field near the town of Shanksville in rural Somerset County,Pennsylvania。In addition to the 19 hijackers,2,973 people died; another 24 are missing and presumed dead。
