Life Is Full of the Unexpected
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 never 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.

课堂小结
达标训练
1. —Why do you look so tired？
—Oh, I prepared for my math test ______ 12 o’clock last night.
A. when B. while C. till D. as
【解析】选C。考查介词的用法。空后是个名词词组，故应用介词，till意为“直到”，as意为“作为”，由答语句意 “我昨晚准备数学考试直到十二点。”可知选C。
2.— James said he would come to my party, but he didn’t 　　　　.
— Really He didn’t keep his word again.
A. show up B. get up
C. set up D. give up
【解析】选A。考查动词短语辨析。show up 出现，露面；get up起床；set up建立；give up放弃。由句意“——詹姆斯说他要来参加我的聚会，但他没有来。——真的吗？他又没遵守诺言。”可知选A。
1. She has gone to Shanghai. (用by the time改写句子)
