will depend on the audience and what you'll be talking about.

　　W：I understand.

　　M：And then, before you start the speech, thank your audience for being there.

　　W：Thank you very much. I have learned a lot from you.

　　W：May I help you?

　　M：Yes, madam. I'd like to buy some flowers.

　　W：Do you want to give them to your girlfriend?

　　M：No, to my wife. God knows that ladies like flowers.

　　W：Today is Valentine's Day. That must be why you want them. Just one day of the year.

　　M：Not exactly. I get them for her birthday, and for all kinds of weird anniversaries.

　　W：But not on April Fool's Day, right?

　　M：Ha ha, right. Oh, and by the way, I want some more for my mother. Tomorrow is her birthday.

　　W：How about these? Purple seems popular with mothers.

　　M：Not with mine. Do you have any other color?

　　W：How about blue or these green ones? They are fresh and bright.

　　M：All right! I will take these green ones and go to the supermarket for some chocolate.

　　W：There is one just across from the bookstore. Here you are! Please come again.

　　M：Thanks! Bye!

　　W：Have you all heard about the White House? Today we're going to talk about the building that symbolizes the USA. Mr. Green, please.

M：The White House is one of the most recognizable structures in the world. You can't say you've been to Washington D. C. if you haven't seen the White House. Not every American president lives there. Though the Executive Mansion was begun in 1792 under the direction of George Washington, the structure was not completed until 1800, so ironically Washington never called it home. The White House is open to the public on weekdays from 10 am until noon. The building was torched by British troops in 1814, during the War of 1812, and the structural damage caused by the fire was repaired, but the sandstone walls outside were still black from the fire. The walls were then painted white, giving birth to the name the building now goes by. An act of Congress made it the official name in 1920. Every President has left his mark upon the White House, with Thomas Jefferson adding grass to the east and west wings, Andrew Jackson installing running water, and Harry Truman adding a porch. Bill Clinton's addition to the White House was an indoor track.
