B

In 1605 some Englishmen planned to kill their king, James I, because they thought he was a bad man. They knew that on November 5th the King would go to the House of Lords(上议院)to talk with his nobles.

The men rented(租赁)a building next to the House of Lords. They dug through a wall and put many barrels of gunpowder in a cellar(地下室) of the House of Lords. They chose a man called Guy Fawkes to set fire to the gunpowder but something went wrong with their plan. One of the men had a relative who was coming to the House of Lords to meet the King. He warned his relative to stay at home. The relative spoke to other nobles and soon the King heard about the danger. Soldiers searched the cellars and found the gunpowder on November 4th ,Guy Fawkes was caught and killed.

Every year, on November 5th, English children remember Guy Fawkes. They collect old boxes, newspapers and rubbish so that they can make a big fire, which they call a bonfire. They put a pole in the middle of the fire and tie a “guy” to it. “The guy” is the figure of Guy Fawkes and is made of old clothes and paper. Sometimes they push their “guy” round the streets in a cart and ask for money so that they can buy fireworks.

In the evening they light the bonfire and let off many fireworks: crackers, rockets, bangers and many other kinds. November 5th is an exciting day for children in England. It is always a busy day for firemen and for hospitals. Sparks from the bonfires sometimes set fire to fences,  trees or houses. Every year children are injured when fireworks exploded unexpectedly.
