Sharks have lived in the oceans for over 450 million years, long before dinosaurs appeared. There are now about 360 of sharks, whose size, behavior, and other characteristics differ widely.
Every year, we catch and kill over 100 million sharks, for food and for their fins. Dried shark fins are used to make shark fin soup, which sells for as much as $50 a bowl in fine Hong Kong . Other sharks are killed for sport and out of fear. Sharks are vulnerable(脆弱的) to overfishing because it most species 10 to 15 years to begin reproducing and they produce only a few offspring.
by movies and popular novels, most people see sharks as people-eating monsters. This is far from the . Every year, a few types of shark injure about 100 people worldwide and kill about 25. Most are by great white sharks, which often feed on sea lions and other marine mammals. They sometimes mistake human swimmers for their normal prey, if they are wearing black wet suits.
If you are a typical ocean-goer, your of being killed by an unprovoked （无缘无故的）attack by a shark are about 1 in 100 million. You are more to be killed by a pig than a shark and thousands of times more likely to get killed when you drive a car.
Sharks help human lives. In addition to providing people with food, they are helping us learn how to cancer, bacteria, and viruses. Sharks are very healthy and have aging processes similar to ours. Their highly effective immune system wounds to heal quickly without becoming infected, and their blood is being studied in connection with AIDS research.
Sharks are among the few animals in the world that almost get cancer and eye cataracts. Understanding why can help us improve human . Chemicals extracted from shark cartilage have killed cancerous tumors in laboratory animals.

It’s a question anyone might ask in the future: Should your household robot be cool? Or practical?
For Sony Corporation, robots ought to be entertaining. The company’s 41 robot, SDR—4 X, can sing and dance.

“It is in the end a machine, a 44 ,” said Masato Hirose, Honda’s chief engineer.
Sony’s chief researcher Toshi Doi said robots performing such tasks as 45for ill or disabled people would not necessarily need a human 46 .
“The attractiveness of the SDR—4 X is its 47”, he said.
“It has feelings. It has instincts(直觉).”

It also 52 off its ability to walk on uneven(不平的)floors, and come to its owner when it’s 53.
While Honda’s robot is 54 used mainly for entertainment, 
it is 55 that one day it will be a useful companion.
So its robot have been 56to be 120cm tall – more than twice the height of the SDR—4 X. Hirose said 120cm is the 5
7a robot that moves around a home should be.
“If you are going to have something that can move with 58 in a human surroundings(环境), then it is better to 59 the robot like a human,” he said.
Hirose said that he hopes the robot will be 60 enough so that he can buy one for himself and let it get him a beer.

Ausubel of Rockefeller University in New York, US. says the key renewable energy sources, including sun, wind and biofuels, would all require vast 1 of land if developed up to large scale production1 – unlike nuclear power. That land would be far better left alone2, he says. Renewables look attractive when they are quite 2 . But if we start producing renewable energy on a large scale, the fallout is going to be horrible. Instead, Ausubel argues 3 renewed development of nuclear.
Ausubel draws his conclusions by analysing the amount of energy renewables, natural gas and nuclear can produce in terms of power per square metre of land used3. Moreover, he claims that as renewable energy use increases, this measure of efficiency4 will 4 as the best land for wind, biofuels, and solar power gets used up.
Using biofuels to obtain the 5 amount of energy as a 1000 megawatt nuclear power plant would require 2500 square kilometres of farm 6 , Ausubel says. "We should be sparing land for nature5, not using it as pasture for cars and trucks," he adds.
Solar power is much more efficient than biofuel in terms of the area of land 7 , but it would still require 150 square kilometres of photovoltaic cells to 8 the energy production of the 1000 MW nuclear plant. In another example, he says meeting the 2005 US electricity demand via wind power alone would need 780,000 square kilometres, an area the size of Texas.
However, several experts are highly critical 9 Ausubel’s conclusions. John Turner of the US government’s National Renewable Energy Laboratory says that 10 the US got all of its power from solar energy, it would still need less than half the amount of land that has been paved over for highways. Further, it need not 11 additional land. The US could get a quarter of its energy just from covering rooftops of 12 buildings, he says.
According to Turner, the same "dual use" also applies to wind power6. "The footprint for wind7 is only 5% of the land that it 13 . Farmers can still farm the land that the turbines are on8. Turner says looking solely at land use is an oversimplification of the 14 . "I’m not sure I’d want to build one of these nuclear plants in Afghanistan9, but we could 15 put in wind and solar power," he adds.

Once in a blue moon there is one on New Year's Eve. Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't 1 it to be blue - the name has nothing to 2 the color of our closest celestial（天体） neighbor.
A full moon 3 on December 2. It will appear again on Thursday in time for the New Year's countdown.
"If you're in Times Square, you'll see the 4 moon right above you. It's going to be that brilliant," said Jack Horkheimer, director emeritus of the Miami Space Transit Planetarium and host of a weekly astronomy TV show.
The New Year's Eve blue moon will be 5 in the United States, Canada, Europe, South America and Africa. For partygoers in Australia and Asia, the full moon does not show up 6 New Year's Day, making January a blue moon month for them.
However, the Eastern Hemisphere can celebrate with a partial lunar eclipse（月蚀） on New Year's Eve when 7 of the moon enters the Earth's shadow. The 8 will not be visible in the Americas.
A full moon occurs 9 29.5 days, and most years have 12. 10 , an extra full moon in a month - a blue moon - occurs every 2.5 years. The 11 time there was a lunar double take was in May 2007. New Year's Eve blue moons are rarer, occurring every 19 years. The last time was in 1990; the next one won't 12 again until 2028.
Blue moons have no astronomical 13 , said Greg Laughlin, an astronomer at the University of California, Santa Cruz.
"`Blue moon' is just a 14 in the same sense as a `hunter's moon' or a `harvest moon,'" Laughlin said in an e-mail.
The popular definition of blue moon 15 after a writer for Sky & Telescope magazine in 1946 misunderstood the Maine Farmer's Calendar and marked a blue moon as the second full moon in a month. In fact, the calendar 16 a blue moon as the third full moon in a season with four full moons, not the usual three.
Though Sky & Telescope corrected the 17 decades later, the definition caught on. For purists（语言纯正癖者）, however, this New Year's Eve full moon doesn't even qualify as a 18 moon. It's just the first full moon of the winter season.
In a tongue-in-cheek essay 19 on the magazine's Web site this week, senior contributing editor Kelly Beatty wrote: "If skies are clear when I'm 20 celebrating, I'll take a peek（眯着眼睛看） at that brilliant orb（天体） as it rises over the Boston skyline to see if it's an icy shade of blue. Or maybe I'll just howl."

At the beginning of this century, medical scientists made an interesting discovery; we are built not just of flesh and blood but also of time. They were 36 to show that we all have “a body clock” 37 us, which controls the 38 and fall of our body energies, 39 us different from one day one to the next.
The 40 of “a body clock” should not be too 41 since the lives of most living things are controlled 42 the 24 hour night-and-day cycle. We feel 43 and fall asleep at night and become 44 and energetic during the day. If the 24 hour-cycle is 45 , most people experience unpleasant 46 . For example, people who are not 47 to working at night can find that 48 of sleep causes them to 49 badly at work.
50 the daily cycle of sleeping and 51 , we also have other cycles which 52 longer than one day. Most of us would 53 that we feel good on some days and not so good on 54 ; sometimes our ideas seem to flow and at other times, they 55 do not exist.

Don't blame genes for aging facial skin. A new study of twins suggests you can 1 those coarse(粗糙的) wrinkles, brown or pink spots, and dilated(膨胀的) blood vessels on too much time in the sun, smoking, and being overweight.
Because twins share genes, but may have 2 exposures to environmental factors, studying twins allows an, "opportunity to control for genetic susceptibility(敏感性)," Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and colleagues 3 in the latest issue of Archives of Dermatology.
Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is 4 more to environment and lifestyle than 5 factors.
But when it 6 skin cancer, the researchers say their findings support previous reports that 7 environment and genes affect skin cancer risk.
Baron's team 8 facial skin of 130 twins, 18 to 77 years old, who lived 9 in the northern Midwest and Eastern regions of the U.S. who were 10 the Twins Days Festival in Ohio in August 2002.
At this time, each of the twins also 11 reported how their skin burned or tanned 12 sunscreen(防晒霜), their weight, and their history of skin cancer, smoking, and alcohol drinking.
The study group 13 of 52 fraternal and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status. Identical(同卵的) twins share all of their genes and fraternal twins share only about half.
From these data, the researchers 14 strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental 15
16 contrast, sunscreen use and drinking alcohol appeared correlated with 17 skin damage.
Baron and colleagues say the current findings, which highlight ties between facial 18 and potentially avoidable 19 factors -- such as smoking, being overweight, and 20 overexposure to the sun's damaging rays -- may help motivate people to minimize these risky behaviors.

Most waste materials are dealr38simply by placing them39.But nuclear waste40be dealt with very carefully. It gives41dangerous radiation and it will continue to be 42for hundreds, thousands, even mil-lions of years.
How should we get rid of such waste material in a43that it will not harm the environment? Where can we safely44it? One idea is to put this45waste inside a 46 container ,47is then dropped to the deep bottom of the ocean. But some scientists believe that this way of dealing with nuclear waste could kill fish and other living things in the oceans48interfere(干扰)with their growth.. Another way49nuclear waste is to send it into space, to the sun, 50 it would be burned. Some scientists suggests suggest that this polluting material51buried thousands of meters under the52surface. Such under-ground areas must be lree53possible earthquakes. Advance id being54,But it may still be many years55this problem could be finally settled.
