Sea horses are unusual parents. The female sea horses lay the eggs, but unlike other creatures, it'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'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't stay long, nor does she take part in the birth.
It takes from two to six weeks for the eggs in the male'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's pouch. When the babies begin moving around, the male sea horse knows it'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'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?
A.Receiving eggs.
B.Laying eggs.
C.Hatching eggs.
D.Protecting eggs.

A new kind of machine【21】to take the place of humans. These machines can do jobs that are too dangerous for humans.【22】, they are being developed to work in nuclear power centers, deep waters and outer space.
This is how the new machines work. A machine is placed in an area far away from the person who controls it. The person wears a special hard hat with tiny television screens. The screens【23】the person see and hear exactly what the machine is seeing and hearing. This gives the person the feeling of being in the same place【24】the machine. The person controls the machine. The machine follows the person's movements exactly. If the person raises his right arm, the machine raises the right arm, too. This means an【25】worker can do a dangerous job while【26】in a safe place. For example, a person can direct the machine【27】a bomb【28】gooing near the bomb himself.
The new machines are not exactly【29】robots. Robots are controlled by a computer. The new machines are controlled by a person. The new machines are called teleoperators. The nuclear power industry is especially interested in teleoperators. The machines could solve the problem of【30】radioactive materials.

Human beings are animals. We breathe, eat and digest, and reproduce the same life【B1】common to all animals. In a biological laboratory, rats, monkeys, and humans seem very much the same.
However, biological understanding is not enough:【B2】itself, it can never tell us what human beings are.【B3】to our physical equipment—the naked human body—we are not an【B4】animal. We are tropical creatures,【B5】hairless and sensitive to cold. We are not fast and have neither claws nor sharp teeth to defend ourselves. We need a lot of food but have almost no physical equipment to help us get it. In the purely physical【B6】, our species seems a poor【B7】for survival.
But we have survived—survived and multiplied and【B8】the earth. Some day we will have a【B9】living on the moon, a place with neither air nor water and with temperatures that turn gases into solids. How can we have done all these things? Part of the answer is physical.【B10】its limitations, our physical equipment has some important potentials.
Inhabitants of our eventual moon colony will bring their own food and oxygen and then create an artificial earth environment to supply necessities.
