Do you remember what you were doing
People often remember what they were doing when they heard the news of important events in history.In the United States,for example,many people remember what they were doing on April 4,1968.This was one of the most important events in modern American history.On this day,Dr Martin Luther King was killed in the city of Memphis in America.Although some people may not remember who murdered him,they remember what they were doing when they heard about the event.
Even the most everyday activities can seem important.Robert Allen is now over 40.He was just a student at that time,but he remembers what he was doing when he heard the news.“It was a bright,sunny day.” Robert remembers.“We were having fun in the playground when the bell rang.Our teacher asked us to stop what we were doing and listen.He told us the news:‘Dr Martin Luther King died just 10 minutes ago!’ We couldn’t believe it!” School closed for the day,and Robert and his friends walked home together in silence.
Dr Martin Luther King’ s murder took place about thirty years ago,before many Americans were born.However,in more recent times,most Americans remember what they were doing when the World Trade Center in New York was destroyed by terrorists.Even the date----September 11,2001----has meaning to most Americans.
Not all events in history are as terrible as this,of course.Many Americana also say they remember what they were doing when man first walked on the moon on July 20,1969.In more recent history,most Chinese remember what they were doing when Yang Liwei became the first Chinese astronaut in space.Yang went into space on October 15,2003.His flight around the Earth lasted about 22 hours.When he returned,he became a national hero in China,and became famous all over the world.
