The long, lonely voyage of the Japanese ghost ship is over.
A US Coast Guard cutter poured cannon fire(开炮) into an abandoned Japanese ghost ship that had been floating since last year’s tsunami, sinking the ship into waters more than 305 meters deep in the Gulf of Alaska and removing the danger it created to shipping and the coastline on Thursday.
The cutter’s guns tore holes in the 164-foot Ryou-Un Maru, and then it began to take on water and lean to one side. In about four hours, the ship disappeared into the sea, said Chief Petty Officer Kip Wadlow.
The ship had no lights or communications system, and its tank was able to carry more than 7,570 liters of diesel fuel. Officials, however, didn’t know exactly how much fuel was aboard.
“It’s less risky than it would be running into shore or running into other ships,” coast guard spokesman Paul Webb said.
The US National Oceanic and Atmospheric Administration and the Environmental Protection Agency studied the problem and decided it was safer to sink the ship than let the fuel evaporate and pollute the sea environment.
Ryou-Un Maru was probably among the first wave of the 1.5 million tons of garbage of refrigerators, washing machines, televisions, roofs and fishing nets heading toward North America since last March when a magnitude 9.0 earthquake struck Japan.
As the coast guard was ready to fire on the ship, a Canadian fishing ship, the 19-meter Bernice C, claimed the rights to save the ghost ship in international waters.
Plans to sink it were paused so the Canadian crew could have a chance to take the stricken ship. A Canadian official with knowledge of the situation told the Associated Press that the Bernice C was unable to drag it.
Then the Canadian boat left, and once it was about 10 kilometers from the Japanese ship, the Coast Guard began to fire, first with 25 mm shells, then a few hours later with ammunition twice that size.
State officials have been working to test the danger of garbage including materials affected by a damaged nuclear power plant, to see if Alaska residents, seafood or wild animals could be affected.

How do you feel after you've stayed up late to finish schoolwork? Or the day after a slumber party? Scientists now say that your answers to these questions may depend on your genes.
Genes are stretches of DNA that work like an instruction manual for our cells. Genes tell our bodies and brains what to do. People have about 40,000 genes, and each gene can have different forms. So, for example, certain forms of some genes make your eyes blue. Other versions of those genes make your eyes brown.
In a similar way, new research suggests that a gene called period3 affects how well you function without sleep. The discovery adds to older evidence that period3 helps determine whether you like to stay up late or get up early.
The period3 gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you.
Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of period3. Study participants had to stay awake for 40 hours straight. Then, they took tests that measured how quickly they pushed a button when numbers flashed on a screen and how well they could remember lists of numbers.
Results showed that the people with the short form of period3 performed much better on these tests than the people with the long form did. In both groups, people performed worst in the early morning. That's the time when truck drivers and other night-shift workers say they have the most trouble concentrating.
After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests took about 18 minutes to nod off.
People with the long period3 gene, by contrast, fell asleep in just 8 minutes. They also spent more time in deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working at top form.

D.Your parents determine what particular combination you have. |
3. People with the short form of period3__________.
A.need to go to bed early and get up early |
B.can work better than the people with long form of period3 without sleep |
C.take less time to fall asleep after they stay up late |
|
D.need more and deeper sleep to keep their brains working at top form |
4.What’s the best title of the passage?
A.The Period3 Gene |
B.The Function of Genes |
C.Wake up, Sleepy Gene |
D.Stay up Late or Get up Early? |
