根据短文内容,回答下列问题。

     Most people like to eat sweets and ice-cream better than meat and rice. If we eat them after a meal,

they're not bad for us. But if we eat them before a meal, they may take away our appetite (食欲). It is

important for us to eat our meal regularly (有规律地) each day. When we feel worried or excited, we

may not want to eat.

    When a man is worrying about something, it is difficult for him to swallow (香) anything dry because

he has little appetite. Many years ago, some judges (法官) in England often gave a man some dry bread

to judge (判断) whether he was telling the truth. If the man could not swallow the bread, they thought he

was telling lies.
