7 . What killed King Tut? Historians and scientists have long believed that ancient Egypt’s most famous king was probably murdered. But a recent scientific study claims to have found a different answer to this more than 3,300-year-old mystery. A team of researchers now say that King Tut, the boy ruler, died of complications (并发症) from a broken leg.

Tut’s full name was Tutankhamun. He was just 9 years old when he became the ruler of Egypt. His treasure-filled tomb was discovered almost a century ago. It was filled with royal riches, including a solid-gold coffin, a gold mask, and piles of jewelry.

Unfortunately Tut died at the age of 19. Many experts have thought that Tut was killed by one of his advisers, named Ay, who wanted to be king. But thanks to a major modern science project, it seems Ay is innocent.

Researchers set out to solve the mystery of King Tut’s death by using the tools of science, including DNA tests and electronic scans of his mummy (木乃伊). Scientist Carsten Pusch conducted the tests on Tut for the new study. He thinks a broken leg contributed to the young king’s death.

More than 100 walking sticks were found in King Tut’s tomb. This supports the team’s findings. But how could a person die from a simple broken leg?

Pusch also found DNA evidence in Tut’s body that indicates he had malaria (疟疾), a disease carried by mosquitoes. Malaria severely weakens the immune system.

Pusch and his fellow researchers believe the malaria and the bone disease together caused the king’s fracture (骨折) to become deadly. Finally, the young king was just too weak to recover. So effects of the disease combined with the bad luck of a broken bone — not a jealous adviser — are likely the real causes of King Tut’s death.

Pompeii was a typical Roman city but was buried by the ashes and rocks     7     (leave) by the eruption of the volcano. Nearly seventeen centuries had rolled away    8     the city of Pompeii was dug     9     its silent resting place. The remains of Pompeii survive     10     (remind) us that human lives burn bright and short.
