en i first saw them, i even thought maybe they’re souvenir coins(纪念币), but when i watched them carefully, i found that they are coins.

　　    coins can be made of different kinds of metal. some are made of nickel（镍）, and some are made of different metal mixture.

　　    now i have a lot of coins from different countries: u.s. dollar, german mark, singapore dollar, thai baht(泰铢) and so on. i think i will go on collecting foreign coins, because it makes me happy every day.

　　教师评语：

　　    it is great that you are interested in the coins of other countries. it is so important to understand the cultures and lifestyles of other countries that all countries can learn from one another and make the world better. well done!
