听力原文: Today we are going to talk about a species of fish that is rather unique: Today's lecture is about sea horses, if you've seen a sea horse, you may have noted that it has a horse-like head attached to its body. The sea horse has a long snout that is good for sucking. Instead of scales like most fish, sea horses have skin that is stretched over bony plates. The body extends to a prehensile tail, meaning that the tail can be used to grasp. The sea horse may grasp sea grass or coral to keep it stable in a moving current.
The sea horse has fins on its back that it can use to propel it through the water. However, sea horses aren't very good swimmers. They do not move quickly over great distances. The sea horse also has chest fins that it uses for stabilization. The chest fins help the sea horse float in an upright position.
One particularly unique feature of sea horse is that only the male becomes pregnant. The female inserts ripe eggs into the male' pouch, where they are fertilized. The eggs become embedded in the pouch wall.
What is this lecture mainly about?
A.Usual Species of fish.
B.Characteristics of a unique sea animal.
C.The harvest of fish eggs.
D.Unusual species of horses.

Sea Horses
Sea horses are unusual parents. The female sea horses lay the eggs, but unlike other creatures,it&39;s the males that give birth to the young.
Male sea horses have a fold of skin on their bellies that forms pocket, called a brood pouch.
During the breeding season, the sea horse&39;s pouch swells to receive eggs. A female sea horse lays up to 200 eggs at a time in the pouch. Then she swims off, leaving her male partner to care for the developing eggs and give birth to young sea horses. The female will return everyday to check on her mate and the eggs, but she doesn&39;t stay long, nor does she take part in the birth.
It takes from two to six weeks for the eggs in the male&39;s pouch to develop. During this time the male avoids open water and hides in sea grass. His big pouch makes it difficult for him to swim,so the male often uses his tail to grasp a piece of sea grass. Firmly gripping the grass, he will stay perfectly still for hours or even days. The male sea horse will change his color to blend with his surroundings and avoid being seen by predators who will try to eat him or poke holes in his pouch to get the eggs.
The eggs hatch inside the male&39;s pouch. When the babies begin moving around, the male sea horse knows it&39;s time for them to be born. He grabs a sea grass stem with his tail and begins rocking, bending, and stretching his body so that the rest of the babies can be born. Sometimes he has to press his pouch against a rock or some stiff seaweed to force the young out.
Sea horse babies are born in groups of five or more. Sometimes it takes two days for the father sea horse to give birth to all his young. He is very tired when it&39;s over.
Soon after giving birth to one brood, the male will approach his mate and show her his empty pouch. This tells her he is ready to receive eggs again.
What part does the female sea horse play in having babies? 查看材料
A.Receiving eggs
B.Laying eggs
C.Hatching eggs
D.Protecting eggs

听力原文: There are many anecdotes about George Washington, the first president of the United States. Among them, there is the following:
Once a neighbor stole one of Washington's horses. Washington went with a police officer to the neighbor's farm to get the horse, but the neighbor refused to give the horse up; he claimed that it was his horse.
Washington placed both of his hands over the eyes of the horse and said to the neighbor, "If this is your horse, then you must tell us in which eye he is blind."
"In the right eye!" the neighbor said.
Washington took his hand from the right eye of the horse and showed the police officer that the horse was not blind in the right eye.
"Oh, I have made a mistake," said the neighbor. "He is blind in the left eye." Washington then showed that the horse was not blind in the left eye either.
"I have made another mistake," said the neighbor.
"Yes," said the police officer, "and you have also proven that the horse does not belong to you. You must return it to Mr Washington."
