CNN News:特朗普将于6月对英国进行国事访问

Name the longest reigning monarch in British history — Queen Elizabeth II, Queen Victoria, King George III, or King Henry VIII. Queen Elizabeth II, the nation's current monarch, has reigned more than 67 years. The longest reign in British history.
The Queen is planning to host U.S. President Donald Trump for a state visit this spring. The United States and the United Kingdom, two close allies, both made that announcement yesterday. The event is scheduled for June 3rd through 5th. The White House says it's an opportunity to reaffirm the steadfast relationship between the two countries. British Prime Minister Teresa May said it would also be a chance to strengthen their cooperation in trade, investment, security and defense.

A state visit is a very formal event. In Britain, it typically includes a horse parade and royal banquet. Only two other U.S. presidents have been invited to one since the Queen ascended to the throne in 1952. She first sent the American leader an invitation two years ago. The countries have been trying to work out the date since then.
