[单项选择]
Our eating habits are very important for good health and a strong body. There are times when most of us would rather eat sweets and ice-cream than meat and rice. Sweets and ice-cream are not bad if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite(食欲). It is important for us to eat our meals at the same time each day. When we feel hungry, it is a sign that our body needs food. When we feel angry or excited, we may not want to eat. A long time ago, in England, some judges used to decide whether a man was telling the truth by giving him some dry bread. If the man could not eat the bread, it showed that he was telling lies. Although this seems very strange and rather foolish, it is indeed a very good way of finding out the fact. A man who is worrying about something has difficulty in eating anything dry. Because he is worrying, he loses his appetite and does not want to eat.
A man who is worrying（）
A. has a better appetite
B. likes to tell lies
C. likes to eat ice-cream
D. has a poor appetite
