  If you go out sometimes at night, you'll see the moon high up in the sky. The moon is far away from the earth.

  But it is our nearest neighbour in space. In 1969 two Americans visited it by spaceship. It was one of the most exciting moments of that year.

  The sky looks black from the moon and you'll see the earth up in the sky. You will also see many, many stars.

  You can't find any living things there. It's too hot in the day and too cold at night. And there's no air or water there. Nothing can live on it.

  It is difficult for men to walk on the moon. Everything becomes much lighter. You can jump much higher on the moon than on the earth. If you throw a ball, it would fly very far. It's very interesting to walk on the moon!

  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 (系统) of numbers. They used symbols (符号) 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.

1

5

10

50

100

500

1,000

L

C

D

M

  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 (减去) 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..

   I used to watch a little girl playing basketball every day from my kitchen window. One day I asked her why she practiced so   1  . She said, “I want to go to college. The only way I can go is   2   a scholarship(奖学金). I like basketball and I want to be the   3  player in college. My dad told me, “If the dream is big enough, the facts don’t count.”

She never changed her mind. I watched her through those high years and into senior high school. One day before she graduated from high school, I saw her sitting on the grass

  4  . I asked her what was wrong. She told me that her coach said she was too short to be a good basketball player, so she should stop  5  about going to college. She was heartbroken and it made me feel bad,   6  . Then she smiled and told me her father said that coach was wrong. He did not understand the power of dream.. Her father said to her, “If you   7  want to play for the scholarship of a good college, nothing but you   8  can stop your dream.” He told her again: “If the dream is big enough, the facts don’t count.”

The next year, she and her team went to a big game. She   9  by a coach of a famous college team and was offered a scholarship to the   10  basketball team of their college. She was to get the college education that she had dreamed of and worked toward for all those years.

“If the dream is big enough, the facts don’t count.” It is true.
