One day in a Chinese zoo, two baby pandas were born. But the mother panda didn’t have enough milk for these two babies, so she fed only one baby and left the other one to die. This is what animals do instinctively when there isn’t enough milk.
Poor baby panda! Do you think he would die? No! The zookeeper had an idea: get a dog to help. Dog’s milk is just like panda’s milk. It can save the baby panda. So the zookeeper put an advertisement in the newspaper: ‘Baby Panda Needs Mama Dog’s Milk.’ By the next day, millions of Chinese saw the advertisement and lots of dog owners called to help. The happy zookeeper picked a healthy dog for the baby panda. Thanks to the kind mama dog, the baby panda grew up healthily.

Where does rain come from?
Rain always comes from clouds. But where do clouds come from? How does all that water get into the sky?
Think about your bathroom. There is hot water in your bath. Steam goes up from the hot water. The stream makes small clouds in the bathroom. These warm clouds meet the cold walls and windows, and then we see small drops of water on the walls and windows.
The world is like your bathroom. The water in the oceans is warm when the sun shines on it. Some of this water goes up into the sky and makes clouds. The wind carries the clouds for hundreds of kilometers. Then the clouds meet cold air in the sky, and we see drops of water. The drops of water are rain.
The rain falls and runs into rivers. Rivers run into oceans. And the water from oceans makes clouds and more rain. So water is always moving from oceans to clouds to rain to rivers to oceans. So the rain on your head was on other heads before! The water in your garden was in other countries.
( ) 1 Rain _______ comes from a blue sky.
A) always B) sometimes C) never D) usually
( ) 2 Hot water makes _______ in the bathroom.

One summer holiday I was in the forest by myself. I went down to fish in the river. Soon I got a big fish. Then I heard a great noise. There, right behind me, sat a big black bear! Wild animals are afraid of any quick move. So I moved very slowly. The bear watched me. But he sat still. I took the fish and threw it to him. He ate it at once.
Now that was I going to do? I’d better go on fishing, I thought. The bear thought so, too. Soon I got another fish. I went over to him and put the fish into his big red mouth. I fished and fished – all for him. At first I was afraid to stop. Then I began to like doing it. He was very friendly.
When evening came, he stood up and turned away from me.
