What do you do if you're served a food that you don't like or cannot eat? If your host doesn'tsay anything about what you aren't eating, then you shouldn't, either．Simply eat what you can andhope that no one sees what you left．If you are questioned, you may have to admit (承认) that youdon't eat meat (or whatever), but you can also say that you've enjoyed the other foods and havehad "more than enough" to eat．
