Our eating habits are very important for good health and a strong body.There are times when most of us like eating sweets and ice cream better than meat and rice.Sweets and ice cream are not bad for us 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’s important for us to eat our meal at regular(規(guī)律)time each day.When we feel worry or excited, we may not want to eat.A long time ago, in England, some judges often decided whether a man was telling truth by giving him some dry bread.If the man could not swallow(吞)the bread, it meant that he wasn’t telling the truth.Though this seems strange and foolish they thought it was good way of finding out truth.A man who is worrying something has difficulty in swallowing anything dry, because he loses his appetite.()1.Good eating habits make us ________.A.strongerB.happier
