Lion is a special animal to Chinese people. A couple of stone lions, a male (雄性) and a female (雌性), can often be seen in front of the gates of old buildings. The male lion is on the left with his right paw (手掌) on a ball, and the female on the right. And her left paw is touching a baby animal.
The lion is the king in the animal world because he is powerful. The ball shows the country or the family will be together forever, and the baby animal with the female shows that you will have many children.
The stone lions were also used to show the families were powerful. If you had no money or power, you couldn’t put the stone lions in front of your houses.
It was also popular to make bridges with stone lions. The best known of this is the Lugou Bridge (also as Marco Polo Bridge), built from 1189 to 1192. The stone lions on the bridge are most famous. Maybe there are 485 lions in all, maybe there are 498 or 501. A famous saying is that “the lions on the Lugou Bridge are uncountable(不可数的).”

小博士：细心的同学们肯定发现了有些名词有单数(singular)和复数(plural)两种形式，而有些名词只有单数形式，这是怎么回事呢？让我来告诉你吧。英语中，名词按其所表示的事物的性质，可分为可数名词(countable noun)和不可数名词(uncountable noun)，可数名词有复数形式，不可数名词一般没有复数形式。名词单数变复数的变化规则见下表。
