Titanic Introduction
The Titanic was a British luxury ship. It sank in the North Atlantic Ocean after hitting an iceberg on its first voyage in 1912. Over 1,500 people died because there were not enough lifeboats. This disaster led to new international safety rules for ships.
“泰坦尼克号”是一艘英国的豪华客轮。1912年首次航行时，它在北大西洋撞上冰山后沉没。由于救生艇不足，超过1500人遇难。这场灾难促使各国制定了新的国际船舶安全规定。
