People have different ways to express love. Once, our teacher asked us to talk about it. There were all kinds of answers. Someone said we could use flowers to express love; someone said we could use languages;（1）someone said we could _____ troubles and happiness _____ each other. A girl told us a true story.
A young man and his wife were both biology scientists. They often did some research（研究） on wild plants in the forest. They had a clever girl and they loved each other.
One day, they went to the forest as usual. But when they climbed up the hill, they were afraid. A lion was watching them. They didn’t bring a gun（槍）with them. It was impossible to run away. Their faces got pale and they stood there without moving. The lion stood there, too. （2） After a few minutes it came up to them slowly, and then it ran faster and faster. It came in front of his wife. Just at that time, the man shouted in a loud voice and began to run away. The lion turned around and began to run after the man. Lions prefer to attack（攻擊）the running person. It is the lion’s character. After a while, the man was killed by the lion. The woman came back safely.
The girl asked us if we knew what the man had said. All the students gave one of these two answers. One was, “Honey, sorry.” And the other was “Hurry, run”. But the girl said we were all wrong. The man shouted to his wife loudly, “Take care of Lily. Live happily.”
At last, the girl said, “At the most dangerous moment, my dad ran away alone. He used the special way to show his love.”

　 The Indians invented and developed the system of numbers from 1 to 9 and 0. We can use the ten numbers to make any number from the biggest to the smallest.

　 However, the ancient Romans invented a different system (系統(tǒng)) of numbers. They used symbols (符號(hào)) and replaced them. 1 is “Ⅰ” and 2 is “Ⅱ”. For larger numbers, they invented new symbols—5 is “Ⅴ”, 10 is “Ⅹ”, and so on. But they didn’t have a symbol for zero.

　 Here’s a table of the Roman numbers.

　 The Romans combined their symbols. In this way, “Ⅶ” means “5+1+1”, or 7. However, they found that “ⅡⅡ” (for 4) and “ⅤⅡⅡ” (for 9) were too confusing, so they thought out another idea.

　 If the “Ⅰ” comes after the “Ⅴ”, then you add it (Ⅵ is 6); if the “Ⅰ” comes before the “Ⅴ”, then you subtract (減去) it (Ⅳ is 4). The rule is that you are allowed to add up to three (e.g. Ⅷ is 8), but only subtract one (e.g. XL is 40).

　 How to remember the symbols?

　 Ⅰis like a finger. In a whole hand, the thumb (拇指) and the little finger make a V. Ten fingers are both hands, so the two Vs make an X..
