关于海豚的英文演讲稿1
One day Mr. Green, the science teacher, asked his class, "What do you want to be when you grow up?"
"I want to be a dolphin trainer like my uncle," Mike answered.
"Why do you want to be a dolphin trainer?" asked Mr. Green.
"Because I'm interested in dolphin language."
"Dolphin language? Tell us more."
"All right," answered Mike, "My uncle tells me that dolphins are very clever. One day my uncle saw a sick dolphin in the pool. It couldn't come up for air. So it whistled to the other dolphins for help. They came to their friend and made some strange sounds. They looked sad. Then together they pushed the sick dolphin's head up above the water. Soon it got well."
"Some scientists once said to my uncle, 'If you live with a dolphin and talk to it all day, maybe you can teach it some words.' My uncle decided to do that. He lived with a dolphin. The dolphin loved to play ball so he decided to teach the word 'ball' first. He threw a ball to the dolphin and said the word 'ball' many times. Soon the dolphin started to say the word."
Kate asked, "How do they make sounds?"
Mike didn't know.
"They make sounds through blowholes in their heads," said Mr. Green. "Scientists know a little about dolphin language, but they have a lot more to learn."
"That's why I want to be a dolphin trainer," said Mike.

Hopefully you already know that dolphins are not fish. Dolphins are warm blooded mammals like us. They breath air through a nostril on the top of their heads called a blowhole. Because dolphins breath air, they must surface periodically. Fish, however, breath by using gills underwater, and therefore do not need to surface. Many fish also have scales, which dolphins do not have. Instead, the skin of a dolphin feels rubbery. A layer of fat, called blubber, under their skin keeps them warm. The locomotion of fish and dolphins is also different. Fish swim by moving their tails from side to side (horizontally). However, dolphins swim by moving their tails up and down (vertically).
How many kinds of dolphins are there?
This question will probably never be answered correctly. As humans, we want to put everything we know of into a group. Some people like large groups with some variation and others like small, precise groups. Not everyone agrees about what marine dolphins deserve their own species name and what ones do not. I currently have 32 species of marine dolphins listed. I am pretty sure that this covers all the species accurately. Most people agree that there are six species of porpoises and five species of river dolphins
Dolphins can understand and interpret some words and actions, they cannot understand us word for word like in the TV show. Even though dolphins may not understand us completely, they might have their own languages. In fact, many people believe that dolphins communicate with languages.

over the years, bill clinton showed himself to be much more than a good politician. his home state elected him governor in the 1970s, the 1980s, and the 1990s, because he was an innovator, a serious student of policy, and a man of great compassion. in the white house, the whole nation witnessed his brilliance and mastery of detail, his persuasive power, and his persistence. the president is not the kind to give up a fight. his staffers were known to say, "if clinton were the titanic, the iceberg would sink."
during his presidency, bill clinton seized important opportunities on issues from welfare to free trade. he was a tireless champion of peace in the middle east. he used american power in the balkans to confront aggression and halt ethnic cleansing. and in all his actions and decisions, the american people sensed a deep empathy for the poor and the powerless. shortly before leaving office, president clinton said, "christ admonished us that our lives will be judged by how we do unto the least of our neighbors." throughout his career, bill clinton has done his best to live up to that standard. and americans respect him for it. at every stage of his remarkable life, president clinton has made and kept countless friends, who share in the joy of this day. and three people in particular have the largest part in this remarkable story. one day more than 30 years ago, inside the yale law library, a fellow student walked over to bill clinton and said, "if you're going to keep staring at me, and i'm going to keep staring back, we ought to at least know each other's name. mine's hillary rodham. what is yours?"that was a good day for both of them, and the beginning of a partnership unique in american history. so today, we honor the former first lady of arkansas, the former first lady of america, the united states senator from new york, senator hillary rodham clinton.
perhaps the clintons' greatest achievement is their daughter, who moved into the white house as a young girl, and left as an accomplished young lady. it's not easy to be a teenager in the white house, but it's a lot easier when you have a loving mother and a loving father that chelsea clinton had.

What is nature
What is nature? It's everything that exists in the world independently of people, such as pants and animals, earth and rocks, and the weather.
Now more and more people are focusing on the nature. It is no doubt that the nature is important to every human being. No nature, no life. Because of the supplies of the nature, we have lived happily for a long time. And we started to gain every thing available from the nature. And this lasted so long a time. Today, people have discovered that the nature around is getting worse and worse.
What is threatening the nature? Air and water pollution, overharvesting of plant and animal species, overpopulation and so on. Overpopulation is the biggest source of pollution. Let's take overpopulation as an example.
What does overpopulation feel like? When we move slowly through the city in a tazi. When we enter a crowded slum district. When the temperature is high and when the air is thick with dust and smoke. The streets are crowded with people. The streets seem alive with people. People eating. People washing. People talking. People sleeping. People visiting each other, arguing and screaming. People relieving themselves. People pushing their hands through the taxi windows, begging. People leading animals. People, people, people, people. As we drive slowly through the crowd, sounding the taxi's horn, the dust, heat, noise and cooking fires made it like a scene from hell! I admit, frightening.
To the nature, overpopulation is a big problem. More people, more pollution. And the big population is threatening the nature every second.
The rapid rise in world population is not creating problems only for the developing countries. The whole world faces the problem that raw materials are being used up at an increasing rate and food production can not keep up with the population increase. People in rich countries make the heaviest demands on the world's resources, its food, fuel and land, and cause the most pollution. A baby born in the United States will use in his lifetime 30 times more of the world's resources than a baby born in India. Unless all the countries of the world take united action to deal with the population explosion there will be more and more people fighting for a share of less and less land, food and fuel, and the future will bring poverty, misery and war to us all.
