“9·11事件”又称“911恐怖袭击事件”、“美国911事件”等，指的是美国东部时间2001年9月11日上午（北京时间9月11日晚上）恐怖分子劫持的4架民航客机撞击美国纽约世界贸易中心World Trade Center和华盛顿五角大楼The Pentagon的历史事件。包括美国纽约地标性建筑世界贸易中心双塔在内的6座建筑被完全摧毁，其它23座高层建筑遭到破坏，美国国防部总部所在地五角大楼也遭到袭击。“911”事件是发生在美国本土的最为严重的恐怖攻击行动，遇难者总数高达2996人。
In May 2001, I found a job in New York at the World Trade Center. On September 11, 2001, I arrived at my building at around 8:30 a.m.I was about to go up when I decided to get a coffee first. I went to my favorite coffee place even though it was two blocks east from my office. As I was waiting in line with other office workers, I heard a loud sound. Before I could join the others outside to see what was going on, the first plane had already hit my office building. We stared in disbelief at the black smoke rising above the burning building. I felt lucky to be alive.
Almost 10 years later, I woke up at 10:00 a.m. on February 21, 2011 and realized that my alarm had gone off. I jumped out of bed and went straight to the airport. But by the time I got to the airport, my plane to New Zealand had already taken off. “This is the first holiday I’ve taken in a year, and now I’ve missed my plane. What bad luck!” I thought to myself. The other planes were full so I had to wait till the next day. The next morning, I heard about the earthquake in New Zealand the day before. My bad luck had unexpectedly turned into a good thing.

1.What time did the writer arrive at World Trade Center on September 11, 2001

Grammar Focus
过去完成时
1、过去完成时的意义
过去完成时表示在过去某个时间或某个动作之前发生的动作或存在的状态，它表示动作发生的时间是“过去的过去”，它是一种相对于一般过去时的时态，没有一般过去时就没有过去完成时
2、过去完成时的句式变化
肯定句:主语+had+过去分词+其他
否定句:主语+had+not+过去分词+其他
般疑问句: Had+主语+过去分词+其他
肯定回答Yes，主语+had.
否定回答 No，主语+hadn't.
3、过去完成时的用法
(1)表示一个动作或状态在过去某一时间或动作之前已经完成，即发生在“过去的过去”。这个过去的时间可以用 by， before 等介词短语或者一个时间状语从句来表示。
例: When I woke up, it had stopped raining.我醒来时，雨已经停了
(2)表示某一动作或状态在过去某时之前已经开始，一直延续到这一过去的时间常与表示延续的时间状语连用，如"by the end of+过去的时间点"，"by the time+从句(一般过去时)"等
例: By the end of last term, we had learned 5，000 new words
到上个学期为止，我们已经学了 5000个新单词
The bus had already left by the time I got there.
到我到那儿时，公共汽车已经离开了
4、过去完成时的判断依据
(1)由时间状语来判定
一般来说，各种时态都有特定的时间状语。与过去完成时连用的时间状语有by+过去的时间点
例: He had finished reading the book by 10 o'clock yesterday.
到昨天10点钟时，他已经读完了这本书。
by the end of+过去的时间点
例: By the end of last year, she had worked in the factory for twenty years
到去年年底，她已经在这家工厂工作20年了
知识拓展
在含有 before，after引导的时间状语从句的复合句中，由于 before和 after本身已表达了动作的先后关系，若主、从句表示的动作紧密相连，则主、从句都可用一般过去时
例:After she closed the door she left the class-room.她关好门后，离开了教室。
表示意向的动词，如hope，wish，expect，think，intend，mean，suppose等，用过去完成时表示“原本......，但未能...... ”
例: We had hoped that you would come, but you didn't.
我们本希望你能来，但你没来。
(3)根据上下文来判定
例: I met Tom in the street yesterday. We hadn't seen each other since he went to shanghai.我昨天在街上碰见了汤姆。自从他去上海后，我们还没有见过面。
