The first chocolate was eaten by people in South America hundreds of years ago.In those days ,people did not really eat chocolate .They used cocoa bean to make chocolate drink and they enjoyed it very much. Many years later ,the cocoa bean was brought to other countries and people came to love the taste of chocolate . 老師，這是一道用所給詞的適當形式填空題，大字體的brought為什么不用備選項里的taken？而卻用brought.
