     James is an American boy. He's going to be a student in a middle school in Shanghai. He wants to know
much about China, because his parents tell him there are many festivals in China. So now he's trying to find
something about Mid-Autumn Festival (中秋节). Here's what his computer tells him.
     Mid-Autumn Festival usually comes in September or October. On that day many families will have a big
dinner. They will send moon cakes to their friends as presents (礼物). Then in the evening people will go out
to celebrate (庆祝) the round moon. It seems bigger and brighter. They also tell the story of Chang'e flies to
the moon. It's the time for all the family members to get together.
     James thinks of Thanksgiving Day in his country. It's almost the same as Mid-Autumn Festival in China.
So he thinks he's going to talk about that to his Chinese friends. Here's what he's going to say:
     The American people celebrate Thanksgiving Day on the forth Thursday of November. On that day people
give thanks to God for giving them a good harvest (丰收). It's usually a family day. People get together to
celebrate the harvest. A big turkey (火鸡) and some pumpkin pies (南瓜派) are their special food for the
festival. They always have a lot of eat.
