difference in temperature between one layer of air in the atmosphere and the next.
On a hot day, light rays from the sky. hit the unusually hot air just above pavement or sand.
These rays bend and then continue horizontally along the line of vision, giving the illusion that a body
of water lies ahead.
Sometimes sailors in northern seas observe ships or icebergs seemingly hanging upside down in
the sky. In this case, the warmer air lies above cooler, denser air. The warm air above reflects the
image of the distant ship or iceberg, even when the same object is not seen directly because of
atmospheric density.
Between the coast of Italy and the island of Sicily lies the Strait of Messina.
For centuries sailors have seen there the mirage of a whole city; this mirage is known as the fatal
marriage (命运注定的婚姻).
Scientists believe that some of the flying saucers that have been reported in many parts of the
United States were actually mirages. When light rays are reflected at night by the warm air above
the earth, the mirage of a lighted object appears in the sky.

big. And they can eat small animals. One famous meat-eating plant is the Venus flytrap (捕蝇草).
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are
like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small
hairs. If a fly touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an
hour, the leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.
Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some
places, the ground is very poor. It doesn"t have all these important things, especially nitrogen (氮).

today. Zoos and research centres look after about 160 pandas. Scientists are studying how they live and
more baby pandas are born in the zoos.
Pandas live in the forests and mountains of southwest China. They mainly live on bamboo, and each
panda needs to eat a lot of bamboo everyday. The area of bamboo is becoming smaller for many different reasons, so pandas have less and less land to live on. Pandas don"t have many babies , and baby pandas
often die. The situation is becoming very serious.
Our government is working hard to save pandas. There are more than 30 nature reserves to protect
pandas but these are not enough. The government has made a new plan to help pandas. The nature
reserves will be bigger and the bamboo will grow better. Then the pandas will have enough food to eat
and enough places to live in. Pandas born in the zoos may go back to live in the nature reserves.
Most people love pandas. The panda is one of the best-known animals in the world. It is the symbol
for the World Wide Fund for Nature. The WWF works to protect all animals in danger, so the panda
has become the symbol of all animals in danger. There is still a long way to go to save the panda. Think
of other animals in danger such as tigers, whales, turtles and elephants-we need to save the panda, and
we need to save them, too.
