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.

Today was not a good day. Everything went wrong. First, I slept late and Mom shouted at me to wake up. When I went to the kitchen for breakfast, there was no cereal. I decided to have some toast instead, but I burned it. I had to eat it anyway because there was no more bread. The juice bottle was empty, so I had a glass of cold water.

When I was getting on a bus, I realized that I had forgotten my wallet, so I had to go back home to get it.

Of course, I missed the bus and had to wait for the next.

I was late for school and the teacher told me to stay in the classroom at lunchtime to catch up on(弥补) the school work I had missed. After lunch, it was time to give the teacher our homework. I reached into my bag to get it, but it wasn’t there. I had left it at home. I was in trouble again.

When I got home, I went straight to my room to catch up on my homework. Mom cooked fish for dinner. She knows I don’t like fish, but she thinks it is good for her son. How terrible! I hope tomorrow will be better.
