Do you know how to keep fish at home?
The fish need room. They must not be crowded（拥挤）. Fish need oxygen(氧气). Fish get it from water in the tank. There must be enough water for all fish in the tank. So the size of the tank is important..
In the tank many people put small plants(植物). They give oxygen to the water. Plants help in other ways, too. Fish can nibble(轻咬)on the plants. They hide in the plants and sleep, lay eggs there.
Both the plants and fish need light. You can put near a window. It will get light there. But remember: a window may let cold air in. The cold can kill(杀死) your fish. Too hot water can kill your fish, too.
The fish need food and you should feed them every day. Giving them too much food is bad. It will make the water dirty. However, the fish should get just enough food. They should finish the food in 10 minutes. No extra(多余) is left. When this happens, the amount(数量)of food is right.

An old farmer lived with his grandson. Each morning, the   16  got up early and read his Bhagavad Gita(薄迦梵歌).
One day the grandson asked, “Grandpa! I try to read the book like you   17  I can’t understand it, and I forget it easily. What’s the   18  of reading it?”
The grandfather said, “Take this coal(煤炭) basket down to the   19  and bring me back a basket of water.”
The boy did as his grandfather   20  ,but all the water ran   21  he got home. The grandfather laughed, “You’ll have to move faster next time.”
This time the boy   22  faster, but again the basket was empty. He told his grandfather that is was   23  to carry water in a basket. He wanted to use a bottle instead, but the old man said, “I just want a basket of water. You’re not   24  hard enough.”
The boy wanted to show his grandfather that the water would surely run. He again put the   25  into the river and ran hard. But there wasn’t anything in it again. He said   26  ,“Look, grandpa, it’s useless!”
“Watch the basket.” said the grandfather.

“Boy, you might not understand or remember   29  when you read the book, but when you read it, you will be   30  ,inside and out. That’s what you got from it.”

When I was 16 years old, a boy gave me an important gift. It was a smile.
It was the early autumn of my first year at a junior high school, and my old school was far away. As a result, no one knew who I was. I was very lonely, and afraid to make friends with anyone.
Every time I heard the other students talking and laughing, I felt my heart break. I couldn't talk about anyone with my problems. And I didn't want my parents to worry about me.
Then one day, my classmates talked happily with their friends, but I sat at my desk unhappily as usual. At that moment, a boy came into the classroom. I didn't know who he was. He passed me and then turned back. He looked at me, without a word, only a smile.
Suddenly, I felt the touch of something bright and friendly. It made me feel happy, lively and warm.
That smile changed my life. I started to talk with other students and made friends. Day by day, I became closer to everyone in my class. The boy with the lucky smile has become my best friend now.
One day I asked him why he smiled, but he couldn't remember smiling at me!
It doesn't matter because all the dark days have gone. I believe that the world is what you think it is. If you think it lonely, you might always be alone. So smile at the world and it will smile back.
