Do you know why different animals or insects have their special colors? Colors are used mainly to protect themselves.
Why can’t some birds easily catch locusts(蝗虫)? It is because locusts change their colors together with the change of the colors of crops. When crops are green, locusts look green. But as autumn comes, locusts change to the same brown color as crops have. Some other insects with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives in the day and appear only at night.
If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals can’t be easily seen by hunters. This is because they have the colors much like the trees.
Have you ever noticed an even more strange thing? A kind of fish in the sea can send out black liquid when it faces danger. While the liquid spreads over, its enemies can’t find it. And it quickly swims away. So it has lived up to now though it is not strong at all.

As many as 10 of the 17 kinds of penguins(企鹅)may be in danger of disappearing. The number of penguins have decreased(减少) by 30% since 1987.
  Penguins are black and white birds that live in the southern part of the world. They are common in South America,New Zealand,Australia and South Africa. Many live near cold waters. But some live near warm waters in Galapagos Islands. Penguins cannot fly,but they are fine swimmers. Penguins eat fish and krill(磷虾).
  The warming of the earth is the decrease in penguin populations. The heating of the air has caused ocean waters to become warmer. Higher water temperatures have reduced the supply of fish and krill. Some years later these birds are completely unable to reproduce(繁殖).  Besides,many adult penguins die of hunger.
  Widespread(广泛的) fishing,exploration for oil and oil leaks(漏) also make penguins be in danger. Poisonous organisms(生物) in ocean water are another danger. Penguins also have their enemies,including wild dogs,sharks,seals and sea lions.
  News about penguins is not all bad,however. Several years ago,oil leaking from a ship hurt 40% of the penguins in South Africa. The penguins became covered with oil. But thousands of people helped clean and treat the birds well. Then they returned the penguins to the wild.  Now these South African penguins are reproducing in higher numbers than before the oil leaking.
【小题1】Penguins ___________.

A.can swim better than flyB.can be found near Oceania (大洋洲)
C.eat fish only冬腊月D.live only in cold waters.
【小题2】Which of the following is NOT the cause of penguin's decrease in numbers?
A.Oil searching.B.Widespread fishing.
C.Human's killing.D.Warming of the oceans.
【小题3】 Why are the penguins in South Africa reproducing in higher numbers than before the oil leaking?
A.Because people removed the ship.
B.Because people sent a lot of penguins to the wild.
C.Because people helped the penguins.
D.Because people treated the penguins well.
