第一篇：My Favorite Song

My Favorite Music)What is your favorite kind of music? Do you like jazz, popular music, classical music, folk songs, blues, and so on? In high school I took one course called music appreciation which I greatly enjoyed.This was not to learn how to play a specific instrument but to learn how to read and listen to music as an art form.We read the stories about the lives of many composers and the history of the musical instruments themselves.Sometimes we listened to tapes at the language laboratory, or concerts.Music is sometimes called a universal language.A composer who cannot speak a single word of our language can make us feel joy and pride, exaltation and despair, peace and mystery through his music.With the rapid development of economy and the excessive using of oil and coal, the air is changing.And such changing also constantly influences the weather and the climate.According to the fourth assessment report issued by the Climatic Change Technical Committee of the United Nations, the human activity is the primary cause of the climate warming for nearly 50 years probablely.The human activity emissions, including the carbon dioxide, the methane, the nitrous oxide and so on, cause the global climate warming.Under the background of the global climate warming, extreme climate occured frequently and the ecological enviroment deteriorated.The air pollution become worse, which threaten the human survival and development.To protect the environment, the government must take even more concrete measures.First, the government should let people fully realize the importance of environmental protection through education.Second, the government should encourage the people to use the environment frienfly product.Finally, those who destroy the environment intentionally should be severely punished.We should let them know that destroying environment means destroying mankind themselves.Animal

Animals live everywhere.They roam the land.They burrow in the ground.They swim in the sea.They fly through the air.They creep, they leap, they soar, and they dive.A very few—including corals and barnacles—stay in one place.Animals come in all sizes.The biggest animals are whales, which can be 100 feet(30 meters)long.The smallest animals can only be seen through a microscope.Zoologists(scientists who study animals)have found more than 2 million species(kinds)of animals.They think they have discovered only a small portion of all animals on Earth.Several things make animals different from other living things.Unlike plants, animals cannot make their own food.Animals eat other living things—plants and other animals—to get energy.Animal bodies are made up of more than one cell, unlike bacteria and other life forms with only one cell.Cells are the building blocks of living things.Animals also have senses, such as eyes or ears, that tell them what is going on around them.WHAT KINDS OF ANIMALS ARE THERE?

Zoologists divide animals into about 30 groups.First, they divide them by whether they have a backbone.Animals that have a backbone are called vertebrates.Animals that do not have a backbone are called invertebrates.The biggest and best-known animals are vertebrates.Mammals, birds, reptiles, amphibians, and fish are vertebrates.You are a vertebrate.Your backbone is also called your spine.There are about 40,000 species of vertebrates.There are far more species of invertebrates.Even though you can probably think of many vertebrates, the many kinds of invertebrates greatly outnumber vertebrates.Almost all invertebrates are small animals.Insects, spiders, mollusks, and worms are all invertebrates.The biggest invertebrate is the giant squid.It can be up to 60 feet(18 meters)long.HOW ANIMALS BREATHE

All animals must breathe oxygen to stay alive.They must breathe out a waste gas called carbon dioxide.Some animals breathe through lungs.Lungs take oxygen out of air.Cattle, dogs, cats, whales, people, and other mammals breathe through lungs.Birds and reptiles also breathe air through lungs.Lungs cannot take air from water.Seals, whales, dolphins, and other mammals that live in water breathe through lungs.They can stay underwater a long time because they can hold their breath for a long time.Sharks and other fish breathe through gills.Gills take oxygen out of water.Snails, slugs, clams, squids, octopuses, and other mollusks breathe through gills.Crabs, crayfishes, lobsters, and shrimp have gills.Gills cannot take oxygen out of air.Some animals breathe through their skin.Insects have small holes in their bodies called spiracles.Air comes in through the holes.Oxygen from the air goes through tubes to all parts of an insect’s body.Amphibians, animals that live on land and in water, can also breathe through their skin.Amphibians also may have lungs or gills or both.Lion

What if you could yell to a friend who lived several miles away—and your friend could hear you? That is how loud a lion can roar!No wonder this mighty animal is called the king of beasts.Lions are big cats.Along with tigers, lions are the world’s biggest and strongest cats.There are two kinds of lions, African and Asian lions.Lions live on grassy plains, savannas, and dry woodlands in Africa and India.They do not like to live in jungles and thick forests.MASSIVE BODIES

Lions have huge shoulders, strong front legs, and powerful jaws.Their paws have long, sharp claws.To keep its claws sharp, a lion draws them in when not in use.Male lions are large and powerful.They weigh from 330 to 550 pounds(150 to 250 kilograms)and stand about 4 feet(about 1.2 meters)tall at the shoulder.Female lions are smaller than males.FUR AND MANE

The fur of grown-up lions can be light tan to reddish-brown.Lions have darker fur on the backs of their ears.Their tails have a tuft of darker fur on the end.Male lions grow a kind of fur collar called a mane.The mane grows around their head, neck, and shoulders.The mane becomes darker and fuller as the lion gets older.It makes a lion appear larger and fiercer to opponents.Cubs, or baby lions, have fur dotted with many spots.The spots help them hide from enemies in brush and clumps of grass.The spots fade as the cubs grow up.WHAT IS A PRIDE?

Lions live in groups called prides.There are as many as 35 males, females, and cubs in a pride.All the females in a pride are related.The females in the pride hunt together and care for cubs together.The males in a pride are not always related.Males join a female pride to mate and produce cubs.Males do not help care for cubs.Males patrol their territory.They try to keep rival males away from their pride.When female cubs grow up they stay with the pride.Males must leave the pride.
