On April 10, 1912, the Titanic started her first trip from Southampton, England, to New York City, US. The ship was the world’s largest and most luxurious（豪华的）one at that time.
　 High-class facilities（设备）for passengers including restaurants, a library and a swimming pool made the ship like a floating hotel. More importantly, its owners and builders said it was unsinkable（不会下沉的）.

　 However, on April 15, the ship sank to the bottom of the Atlantic Ocean and killed over 1,500 people.　

This April 15, on the 100th anniversary（周年纪念）of the sinking of the Titanic, people in the UK and US will hold activities to remember the event. James Cameron’s 1997 film, Titanic, was a huge hit all around the world. Now the 3-D film will come to Chinese theaters on April 10. It is a love story between a poor young man named Jack and a rich young woman named Rose on the unlucky ship. In Belfast, UK, the port of the Titanic’s birth, a museum called Titanic Belfast will open to the public.
　Today, the sinking of the Titanic is not just an accident. It has become a popular expression to mean a large disaster or mistake, usually because of too much confidence.
　In the UK, if somebody says that his or her mobile phone is really great and could never break, others might say, “Yeah, and people said the Titanic was unsinkable.” In other words, no matter how confident or proud people are about something, anything can go wrong.
