¡¾1¡¿ Thirty years ago£¬ Lake Ponkapog was full of life. Many birds and animals lived beside the water£¬ which was full of fish. Now there are few birds£¬ animals and fish. The lake water is polluted. It is filled with strange plants.
¡¾2¡¿ How did this happen? First£¬ we must think about how water gets into Lake Ponkapog. When it rains£¬ water comes into the lake from all around. In the past£¬ there were forests all round Lake Ponkapog£¬ so the rainwater was clean.
¡¾3¡¿ Now there are many homes around the lake. People often use chemicals in their gardens. They use other chemicals for cleaning or killing insects. There are many factories using chemicals in their machines. When it rains£¬ the rainwater picks up all the chemicals from homes and factories and then carries them into the lake. They pollute the water and kill the animals.
¡¾4¡¿ Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats. But oil and gas£¨ÆûÓÍ£©often get into the lake£¬ so more bad chemicals go into the water in this way.
¡¾5¡¿ People around the lake love their lake and want to save it. A clean lake must have clean rainwater going into it. Clean rainwater is possible £¬only if people are careful about chemicals at home and at work. They must also be more careful about gas and

In the deserts(ɳĮ)of North Africa and Saudi Arabia lives the smallest fox with the largest ears. This animal is the fennec fox.
Fennec foxes have ears that are 5 to 6 inches long. That¡¯s big for an animal that weighs less than four pounds. Their ears help shed (È¥³ý) body heat. And, as you may have guessed, they also provide great hearing.
It¡¯s also interesting to think about the hair of fennec foxes. Why would a fox that lives in the desert need a thick, fur coat? Actually, the desert isn¡¯t always warm. During the nighttime, a desert can be terribly cold! A fennec fox¡¯s fur keeps them warm during those desert nights. They also have long bushy tails that they use as a blanket. And the hair on their feet protects them from the hot sand in the daytime.
Fennec foxes live in small communities of dens (ÊÞѨ).They spend most of the day sleeping in their dens, out of the hot sun. Then, when night comes, they come out in search of food. In addition to(³ý¡¡Ö®Íâ) their great hearing, fennecs also use their great sense of smell and big eyes to track down dinner.
Fennecs eat both meat and plants. They like eating birds, eggs, insects, snails, fruit and leaves best. Fennec fox mothers have one to five babies at a time. Sometimes they are in danger. They have to be careful with predators (²¶Ê³ÐÔ¶¯Îï), such as caracals (a type of wild cat) , jackals, eagle owls, hyenas and humans. Humans catch them for their fur and/span> to sell as pets.
