    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.

    Water can be a liquid, a solid or a gas. When it is a solid, it can be as hard as stone. When it is a liquid, it can run through your fingers. When it is a gas, you may not see or feel it.
    Water can change from a solid to a liquid or to a gas easily. This is why we always have fresh water. Now let us find out how it does. The heat of the sun turns liquid water into gas from the oceans, seas, rivers and lakes. The heat also turns liquid water into gas from the ground, the plants and the animals. Water in the gas rises and turns into clouds in the air.
    When the clouds come near a mountain, they rise high. As the clouds rise, they get cooler. The higher they rise, the cooler they become. Then more and more water gas turn into water drops. In this way, the drops of water in the clouds get bigger and bigger. Then they fall to the earth as rain.
