Butterflies（蝴蝶）are common all over the world but the ones in hot countries are usually bigger and more brightly colored than those in cooler countries, and there are more different kinds.

　　Usually the male（雄性）butterfly is more brightly colored than the female （雌性）. The females have bigger and heavier bodies, since they carry the eggs. The gay colors of the male help to attract the female and the duller（暗淡的）colors of the female make them less likely to be caught by enemies before they have laid their eggs.

　　Some butterflies have a bright pattern of colors on the upper Surface of their wings which show when they fly, but when they rest on a tree or leaf, they close their wings. On the undersides of their wings there are green and brown markings which look like the trees or leaves. They are then difficult to be seen. The best example of this is the Dead leaf Butterfly. When its wings are closed, it looks exactly like a dead leaf. There are even marks that look like the holes in a dead leaf. When a bird is chasing（追逐）a butterfly, and the butterfly closes its wings, it cannot be seen. When a bird sees one, and begins to attack it, the butterfly opens its wings. The bird thinks that it sees two eyes staring at it, and, frightened, it flies away.

There were once three little butterfly（蝴蝶）brothers, one white, one red, and one yellow. They played among the flowers in the garden, but never grew tired because they were so happy. One day there came a 1rain, and it wet their wings. They 2 home, but when they got there they found the door3and the key gone. So they had to stay outdoors in the 4 .
Soon they flew to the 5 and yellow tulip（郁金香）, and said, “Friend Tulip, will you open your flower and let us 6 till the storm is over?” The tulip 7 , “The red and yellow butterflies may enter, because they are 8 me, but the white one may not come in.” 9 the red and yellow butterflies said, “If our white brother may not find shelter in your flower, we’ll stay 10  in the rain with him.”
It fained harder and harder, and the 11 little butterflies flew to the white lily and said, “Good Lily, will you 12 your bud（花蕾）a little so we may fly in out of the rain?” The lily answered, “The white butterfly may 13 , because he is like me , but the red and yellow ones must stay outside in the storm..” Then the little white butterfly said, “If you won’t 14 my red and yellow brothers, I’ll stay out in the rain with them. We would rather be 15 than be separated.”
So the three little butterflies flew away. But the 16 , who was behind a cloud, 17 it all, and he knew what good little 18 the butterflies were.
