     Michael Jackson, the American pop legend, died of a cardiac arrest (心脏骤停) in a Los Angeles

hospital, just weeks before he hoped to resurrect (复活) his four-decade long career with a series of

sold-out shows in London. The pop superstar was taken to the University of California at Los Angeles

medical centre last night, and doctors tried resuscitation (使苏醒,使复活) in the ambulance. He did not

regain consciousness and was reported dead about three hours later.

    "My brother, the legendary King of Pop, passed away on Thursday 25 June at 2:26pm," his brother

Jermaine said, "We believe he suffered a cardiac arrest at his home, however the cause of his death is

unknown until the results of the autopsy (验尸) are known. The personal physician who was with him

at the time attempted to resuscitated him."

    A spokesman for the UCLA medical centre said, "When he arrived at hospital at approximately

l:14pm, a team of doctors attempted to resuscitate him for a period of more than one hour, but they

were unsuccessful." Police said they were investigating, which is the standard procedure in such cases.

    Jackson's death brought a tragic end to a long decline from his peak in the 1980s when he was music's

greatest all-around performer, a uniter of black and white music who shattered the race barrier on MTV. His 1982 album Thriller, which included the blockbuster hits Beat It, Billie Jean and Thriller is still the

best-selling album of all time, with over 50m copies sold worldwide.

     The world famous entertainer had planned a series of 50 concerts in London from 12 July. Although

in the last two decades his reputation was destroyed by charges of child molestation (骚扰) and his

fantastic public behavior, all tickets were sold within hours, proving the King of Pop had enduring appeal.
