限界门两支柱中心连线应尽量（）公路。

Now more and more people in the world are getting fatter. This troubles them a lot. Experts(专家) say that it has a lot to do with  our eating habits.

Our eating habits are very important for good health and a strong body. Most of us like eating sweets and ice cream better than vegetables 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 in the same period  each day. When we feel worried or excited, we may not want to eat. A long time ago, in England, some judges(法官) often decided whether a man was telling the 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. Because when a man is worried about something, he will have trouble in swallowing anything dry, because he loses his appetite.
