Both warm-blooded and cold-blooded desert animals have ways to escape the desert heat. Warm- blooded desert animals, such as rats and mice, rest during the day, often staying in cool underground burrows. At night they search for food. Animals that are out during the day, such as cold-blooded lizards and snakes, are active only for short periods. As their body temperature rises, these reptiles（爬行动物） move into the shade in order to cool down. In the early evening, when the sun grows weaker, the reptiles become more active and begin their search for food again.

　　Getting enough water to survive is a major problem for all desert animals. Some desert animals, like desert birds, manage to find water holes. Other desert animals, such as the kangaroo rat and the related jerboa, get water only from the food that they eat. Because these animals eat mainly dry seeds, they must survive on a tiny amount of water.

　　Most deserts have only a small number of frogs and toads because these animals must be near water to survive. Yet even these creatures have adapted(适应) to desert conditions. When small amounts of water collect in temporary streams, the desert-living frogs and toads become active. After a rainfall, they lay their eggs. The eggs grow into tadpoles in a few days and into adults in just four weeks. When the puddles(水坑) dry up, the adult frogs or toads dig into the ground. Their metabolism(新陈代谢) slows, and they stay beneath the ground until the next rain, which may be as good as a year away. Until then, their bodily activities continue at a reduced rate.

　　The camel ― often called the ship of the desert ― is one of the most successful desert animals. Camels can go for long periods without water, but eventually they must drink. When water becomes available to them after a long drought, they may drink 95 liters of water or more. When water is not available, what helps camels survive the desert heat is the fat stored in their humps(驼峰). A camel’s hump contains about 12 kilograms of fat. Fat is rich in hydrogen. As the fat is digested, hydrogen from the fat combines with oxygen in the air that the camel breathes. The result is H2O, or water. Each kilogram of fat that a camel digests produces about a liter of water.

　　Snake dishes have become popular in recent years. Snake meat in various flavors（风味）is often seen in restaurant ads. It seems that eating snake is now in vogue（盛行）, and if you haven’t eaten snake yet, you are considered “out of date”. But I wonder whether all of the trends are worth following.

　　Some people may defend themselves by saying that snake meat is nutritious（有营养的）. But these people don’t realize that mice and worms often comprise a snake’s diet, therefore, there are many parasites（寄生虫）found inside snakes. Thus, they may do harm to our health. Apart from this, I’m sorry to see that more and more snakes are being killed by man’s cruel knife.

　　According to the English newspaper Shanghai Star, about 1, 000 tons of snakes are eaten every year in China. In Shenzhen of Guangdong Province, sometimes as many as 10 tons of snakes are served on dinner tables in a single day.

　　These figures alert us that if we still turn blind eyes to this continuous movement against snakes, a vicious cycle will be created. If more snakes are eaten by people, the number of snakes will drop, which will make an increase in mice and worms population, which will result in a decrease of crop output. This will make more people hungry.

　　Who will see such tragedy happen?

　　So let’s start not to eat snakes any more because “to protect the snake is to protect ourselves”.

　　1．This passage tries to advice people ________.

　　D．Mice will damage the crops.

　　4．The vicious cycle may be like this: ________.

　　A．more snakes→more mice and worms→less crop output

　　B．less snakes→more mice and worms→more crop output

Have you ever heard the story of the four-minute miles? Many years ago, people believed that it was impossible for a human Being to run a mile in less than four minutes until Roger Banister proved it wrong in 1954．
