Hi you would need to introduce your talk, eg Ladies and gentlemen, tonight I am here to tell you about food around the world.All countries have their national dishes to celebrate special occasions. such as the New Year.. In China people eat eight, ten or twelve dishes of food at New Year. This is because an even number means double the luck. A lot of the food at New Year has a special meaning. Seaweed means good luck and long noodles mean long life. They eat whole vegetables and don’t use knives to cut things, because this means the end of your good luck. In Russia there is lots of food on the table so the next year will be happy and plentiful. At 11.59 people open champagne and wait for the clock to strike twelve. Then they make a toast for the New Year. They wish everybody good luck and happiness. In Spain people eat twelve grapes – one with each chime of the clock at midnight. This brings good luck for the next twelve months. But it is difficult to eat twelve grapes in twelve seconds, so people usually have a mouth full of grapes at the end!
