　　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.

Not many years ago, a wealthy and rather strange old man named Johnson lived alone in a village in the south of England. He had made a lot of money in trading with foreign countries. When he was 75, he gave £12,000 to the village school to buy land and equipment for a children’s playground.
As a result of his kindness, many people came to visit him. Among them was a newspaperman. During their talk, Johnson remarked that he was 75 and expected to live to be 100, and the newspaperman asked him how he managed to be healthy at 75. Johnson had a sense of humor. He liked whisky and drank some each day. “I have an injection(注射)in my neck each evening”, he told the newspaperman, thinking of his evening glass of whisky.
The newspaperman did not understand what Johnson meant. In his newspaper he reported that Johnson was 75 and had a daily injection in his neck. Within a week Johnson received thousands of letters from all over Britain, asking him for the secret of his daily injection.

Heavy downpours last month in Rhode Island led to widespread flooding, causing millions of dollars in property damage and leaving thousands homeless. The flood waters also poured vast amounts of raw sewage(未经净化的污水) into the rivers and streams that flow into Narragansett Bay.
It sounds like the makings of an environmental nightmare. But in fact it’s just the opposite. To scientists’ delight. The sewage-loaded floodwaters have caused a well-timed growth of phytoplankton. The microscopic creatures that form the foundation of marine(海洋的) food chains. With more food available for fish. Clams and other sea creatures. The bay’s fisheries industry is expected to benefit.
In decades past. Narragansett Bay typically experienced a late winter early spring algal(海藻) bloom that fed creatures up and down the water column. But in recent years, the waters of Narragansen Bay warmed greatly, meriting this seasonal event.
Mark Berman, an oceanographer with the Nationa. Marine Fishertes Service. Said the flood seemed to have sent the bay back in its normal state.
However, local, mutate and federal officials in Rhode Island leave been batting other algal blooms that, by contrast, are causing widespread harm to the Narragansett Bay ecosystem. During summer months, sewage and agricultural runnel flows into the bay. Causing large blooms. But inseam of becoming food for sea creatures, much of the phytoplankton is consumed by bacteria, which grow last in the warmer waters. The rapid bacteria growth leads to hypoxia decrease of oxygen in the water that can cause large fish tools. One such die-off occurred in 2003. when millions of oxygen-starved fish washed up on the belches of Narragansett Bay.
The flood’s positive impact will probably be a one-time event, Mr Berman said. Mcanwhile efforts to curb the harmhl summer honors continue; in 2003. for instance, Providence completed a $359 million sewage tonal under the city designated to reduce the polluted storm overflow into Narragansett Bay.
71．Scientists believe that the row sewage flowing into the bay will .

A．pollute the local natural environment
B．increase the prcducmon of fishery industry
C．cause large fish kills of the bay indirectly
D．provide too much food ior sea creatures
74．It can be inferred that .
A．money spent on the summer blooms has been wasted
B．the government is inverting to promote the local fisheries
C．research of accanology should he encouraged
D．she raw sewage impacts are currently con radiator
75．The underlined word “carb” n the hast postage can be defined as “ ”.

An old problem is getting new attention in the United States—bullying. Recent cases included the tragic case of a fifteen-year-old girl whose family moved from Ireland. She hanged herself in Massachusetts in January following months of bullying. Her parents criticized her school for failing to protect her. Officials have brought criminal charges against several teenagers.
Judy Kuczynski is president of an anti-bullying group called Bully Police USA. Her daughter Tina was the victim of severe bullying starting in middle school in the state of Minnesota. Her said, "Our daughter was a very outgoing child. She was a bubbly personality, very involved in all kinds of things, had lots of friends. And over a period of time her grades fell completely. She started having health issues. She couldn't sleep. She wasn't eating. She had terrible stomach pains. She started clenching her jaw and grinding her teeth at night. Didn't want to go to school."
Bullying is defined as negative behavior repeated over time against the same person. It can involve physical violence. Or it can be verbal — for example, insults or threats. Spreading lies about someone or excluding a person from a group is known as social or relational bullying.
And now there is cyber bullying, which uses the Internet, e-mail or text messages. It has easy appeal for the bully because it does not involve face-to-face contact and it can be done at any time.
The first serious research studies into bullying were done in Norway in the late 1970s. The latest government study in the United States was released last year. It found that about one-third of students age twelve to eighteen were bullied at school.
Susan Sweater is a psychologist at the University of Nebraska-Lincoln and co-director of the Bullying Research Network. She says schools should treat bullying as a mental health problem to get bullies and victims the help they need. She says bullying is connected to depression, anxiety and anti-social behavior, and bullies are often victims themselves.

And, on the basis of a bit of email correspondence and seeing a photo of the sofa belonging to 'A. N. Unknown', would you travel halfway across the world to do the same?
