           B

All animals are part of the food chain: they are listed on someone else’s menu and always run the risk of ending up as someone else’s lunch, dinner or snack.

  To protect themselves from being eaten and to survive in the wild, many animals have developed clever ways to escape from or avoid danger.

Like human beings, animals often try to hide or run away when they are being attacked. Many animals have adapted to their environment in such a way that they can hide better. Having the right colour can make a difference. Many animals have the same or similar colour as their environment, making it more difficult for other animals to find them. Some can change colour very quickly, even in a few seconds. Other animals and insects have a body shape that helps them hide. Some insects look just like a small stick and can easily hid in a tree or bush.

If it is too late to hide or run away, an animal must use other methods to survive an attack. One type of snake that lives in Texas has developed an interesting way to defend itself. If it is attacked, it first makes itself look bigger and pretends to be a dangerous snake. If that doesn’t work, the snake uses another trick: it rolls over, opens its mouth and acts as if it were dead. The snake is such a good actor that it seems quite dead. If someone picks it up, it hangs like a rope and doesn’t move. However, if you roll it back on its stomach, it will roll over on its back again in order to look dead.

Another way to survive an attack is to have useful body parts. The turtle has a thick shell that protects it from its enemies, and other animals have teeth, claws, and horns that they can use to defend themselves. There are also animals that can use their tails to fight off attackers. A long tail can be used to hit an attacker, and there is even an animal whose tail will break off so that it can run away if someone grabs it.

The best way to stay safe is to develop a way to receive an early warning when danger comes. Many animals stay together in large groups and use sounds and body language to warn each other if they see or hear something suspicious. Some animals even work together with other species to say safe. The birds you often see on the back of a water buffalo have an important job: they help warn the buffalo of danger.

A

When researchers made their first clone of an animal, Dolly the Sheep, in 1997, one doctor said: “The genie (妖怪) is out of the bottle.” But then he tried to actually create the “genie”--- by making a human clone.

Dr. Panayiotis Zavos told the public on October 5 that he could create the first cloned human before the end of the year. He is an expert on human copying and breeding from the University of Kentucky in the United States.

His workers have been stopped from carrying out research in most European Union countries, but Zavos said that fact was not slowing progress.

“It is going well enough so we may try the first production of cloned embryos in the very near future, that is, three or four months from now.” Cypriot-born Zavos said. He moved to the United States over 30 years ago.

Human cloning could, in effect, create a copy of another living or dead person.

But Zavos insisted there was nothing harmful in the project. As an expert on human reproduction, he said he is only interested in helping couples who cannot naturally have babies to have a child.

“We are not interested in cloning people like Bin Laden, Michael Jackson or Michael Jordan,” the doctor added.

“We are only interested in helping a father who does not have the ability to have a biological child of his own.”

Zavos said thousands of childless people from all over the world are helping in their research.

He would not say where the research is under way, but indicated that it is in more than one country.
