A、The Paris of the West. B、The heroism of the survivors. C、100th anniversary of the Great Earthquake. D、The immense destruction.

Thousands will gather in the city center just after 5:00 am on Tuesday, April 18, to remember victims of the Great Earthquake. Organizers say they will also celebrate the heroism of the survivors. One hundred years ago, the first small shock struck at 5:12 in the morning, and the region shook violently for one minute. A center of culture and commerce, San Francisco was then known as the Paris of the West. Just hours earlier, Italian tenor Enrico Caruso had appeared in the opera Carmen at the city’s opera house. The singer later recalled trembling with fear as he looked out of the window of his room at the Palace Hotel. He saw buildings collapse,  and heard the screams of men, women and children. Historian Eileen Keremitsis is a volunteer guide who describes the tragic story for visitors. The quake was massive and it was centered just off the coast close to the city. The shaking damaged or destroyed thousands of buildings over a wide area, but Keremitsis says most of the severe destruction was caused by fires that burned uncontrolled for three days.
