which word? 词语辨析

• A bitter taste is usually unpleasant, but some people enjoy the bitter flavour of coffee or chocolate. No other word can describe this flavour. A sharp or pungent flavour is more strong than unpleasant, especially when describing cheese. Sharp, sour and acid all describe the taste of a lemon or a fruit that is not ripe. An acrid smell is strong and unpleasant, especially the smell of smoke or burning, but not the smell of food. * bitter 指味道通常为苦的、令人不快的，有人却喜欢咖啡或巧克力的苦味。没有其他词可用来形容这种味道。sharp 或 pungent 主要强调味道强烈而非令人不快，在描述奶酪的味道时尤其如此。sharp、sour 和 acid 均形容柠檬或未熟水果的酸味。acrid 指气味强烈而令人不快，尤指烟味或燃烧产生的气味，但不用来形容食物的气味。
