I didn't see this problem until 1 1 in the evening. I may have answered a little late. I hope I can still help you. In fact, all the information can be found online, and then you can find the sample drafts of statements, ultimatums and judgments yourself, imitate them and organize the language.

A statement by killer whales

Hello, I'm a killer whale. Everyone knows that I am a well-deserved fish by looking at my vigorous posture in the water and the same shape as a fish. For a long time, someone mistakenly classified me as a mammal, which made me very angry! ! ! I hereby declare that my killer whale will become the king of fish in the ocean and will never be a mammal again!

The ultimatum of sharks

Hello, everyone, I'm a shark that has become a mother. As we all know, the way we sharks reproduce is viviparous just like our distant relatives on the shore-other mammals. But someone just got in the way and classified our species as fish. And we are the characteristics of mammals: our cubs are all breast-fed. Faced with such a serious mistake, today I shark will issue an ultimatum on behalf of our species: being an animal can't be so shameless! ! ! Give us justice within 5 days and restore our true identity-mammals!

Supreme Maritime Court (2006) Min San Zhong Zi No.30

The plaintiff killer whale filed a lawsuit on XX, XX, XX, requesting to leave the mammal.

The plaintiff Shark filed a lawsuit on XX, XX, XX, requesting proof of his mammal identity.

Now the defendant's lawyer provides the following materials:

Sharks Sharks belong to the order Sharks. They are carnivorous marine fish.

Sharks, also known as sharks and sharks, are cartilaginous fish. The body is spindle-shaped, and the eyes are mostly on both sides of the head, without swimming. Living in the deep sea. There are more than 300 kinds of sharks in the world, the gentle shark eat small fish shrimp and shellfish; Fierce sharks will eat marine animals and even attack humans. Most of them are oviparous or viviparous, and a few are viviparous.

Black whales and black whales live in the ocean all their lives. Adapted to the aquatic life, the whale's body has become similar to that of a fish: the head and trunk are directly connected, and the neck is not obvious; Tail is specialized as caudal fin; The forelimbs become fins and the hind limbs have degenerated; The body surface is smooth and hairless. There are significant differences between whales and fish: whales breathe with their lungs; The heart is divided into four chambers; There is a diaphragm in the body cavity; Constant body temperature; Viviparous; Breastfeeding. All these characteristics show that whales are mammals, not fish. Black whales can mate all year round. Females give birth every 3-5 years. The gestation period is 1 year, and each fetus gives birth to 1 offspring. The lactation period also needs about 1 year, and the life span is about 20-35 years. During the period of 1-2 years after birth, when the larvae are hungry or call for females, they can only make a hoarse voice. Later, with the growth of age, they gradually imitated the voices of adults and improved and enriched their calls. However, because the language of killer whales is complex and changeable, it takes at least five years for young whales to fully master the "language" of adults.

At the same time, it also received scientific research support from Mr. Kant, a doctor of zoology. The answer he provided is as follows: sharks are primitive and viviparous, and they can also keep their body temperature constant so that they have enough strength to attack quickly. But it's not a mammal. Shark is a kind of fish, belonging to the fish class; Mammals are all mammalian sharks that breathe through gills, while mammals use lung sharks not to breastfeed their young. And mammals are breast-fed. In addition, regarding the viviparous of mammals, it should be noted that there are exceptions such as platypus. Sharks are also an exception among fish. Usually fish lay eggs, while sharks are viviparous.

In view of sufficient materials and conclusive evidence, the plaintiff's request is rejected.

Make the following judgment: killer whales belong to mammals and sharks belong to fish.

This is the final judgment, and there is no appeal.
