The amazing image shows the world’s largest ever cruise ship, complete with beach pool, shopping mall, rock-climbing walls, outdoor amphitheater（圆形剧场）and New York-style loft suites（套间）．The “traveling city” is being built on dry-docks in Finland by Royal Caribbean International, and she is named Oasis of the Seas．
Almost 1,200 feet long, 154 feet wide and rising 213 feet above the water line, the Oasis of the Seas will be able to host 3,000 crew to service every passenger’s need．In addition to the size, the Oasis of the Seas will also be the first ship that attracts people by the cruise line’s new neighborhood concept: 7 distinct themed areas, including Central Park, Boardwalk, the Royal Promenade, the Pool and Sports Zone, Vitality at Sea Spa and Fitness Center, Entertainment Place and Youth Zone．Of all these areas, the excellent zone will be “Central Park”．
Protected from the weather by a clear screen to let in the light, the Central Park area will be themed on Caribbean plants and leaves reflecting the area which the ship will eventually cruise in．And the park zone will have different restaurants, bars and boutique shops, bringing the idea of “floating city” to reality．
In addition, Oasis of the Seas will also include a rock wall, over 15 restaurants and bars, a casino(娱乐场), a theatre, two night-clubs and the largest freshwater pool on any cruise liner．

A breathtaking trick potentially left over from our ancestors might be found in us — the ability to sense oxygen through our skin.
Amphibians, animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo.
Now the same oxygen sensors found in frog skins and in the lungs of mammals (哺乳动物) have unexpectedly been discovered in the skin of mice.
“No one had ever looked,” explained Randall Johnson, a biologist researcher.
Mice and frogs are quite distant relatives, so the fact they have these molecules (分子) in common in their skin suggests they might well be found in the skin of other mammals, such as humans.
“We have no reason to think that they are not in the skin of people too,” Johnson said.
These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen—a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1a genetically removed from their skin failed to produce this hormone (荷尔蒙) even after hours of such low oxygen.
These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia (贫血症) without injecting drugs, which make up a multibillion-dollar market, Johnson said.
Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. “It’s hard to say what exactly might be done, however—there’s a lot we don’t know yet,” Johnson explained.
The scientists detailed their findings in the April 18 issue of the journal Cell.Which of the following statements is TRUE according to the passage?
| A．It has long been expected oxygen sensors exist in mice’s skin. |
| B．People have to surf the Internet to read detailed findings. |
| C．It has been proved that these findings help treat lung diseases. |
| D．Johnson believes that Oxygen sensors also exist in human skin. |
One of the functions of the molecules mentioned above is _______.
| A． increasing level of oxygen | B．improving athletes’ performance |
| C．detecting oxygen | D．carrying oxygen around the body |
What is Johnson’s attitude to the application of the findings to the athletes’ training?
| A． Hesitating | B．Doubting | C．Positive | D．Negative |
The best title of the passage may be _______.
| A． Humans Might Sense Oxygen Through Skin |
| B．Frogs And Mice Are Distant Relatives |
| C．First Known Animal Breathes Through Skin |
| D．Great Findings Benefits Athletes A Lot |
Bad teeth can be painful -- and worse. They can even be deadly. Infections (感染) of the gums (牙龈) and the teeth can cause bacteria (细菌) to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk.
For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齿保健) he needed. He was twelve years old.
Experts at the National Institutes of Health say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow the growth of bacteria and acid production in the mouth.
But dentists say a baby's gums and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, only give the child water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently.
The use of fluoride (氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel (珐琅质) , the hard surface on teeth, to help prevent holes from forming.Which of the following can be used as the title of the passage?
| A．Concerns for Healthy Teeth of the Young |
| B．Causes of Teeth Problem |
| C．Importance of Healthy Teeth of All |
| D．Solutions to Teeth Problem |
What's the main idea of paragraph 4 and 5?
| A．How to develop babies' teeth. | B．How to keep babies' teeth clean |
| C．Why to protect babies' teeth | D．Why to keep babies' teeth clean |
The passage indicates that ______.
| A．Enamel is most widely used to protect teeth in the world |
| B．Breast milk can cure babies' bad teeth |
| C．Bad teeth may affect the health of adults and the young |
| D．Babies' teeth should be brushed once per day |
The writer uses the boy's death as an example to show that ______.
| A．not only adults but the young may suffer from teeth problem |
| B．the doctors should be responsible for the case |
| C．babies with bad teeth can easily die |
| D．the boy was not fed with his breast milk |
The long, lonely voyage of the Japanese ghost ship is over.
A US Coast Guard cutter poured cannon fire into an abandoned Japanese ghost ship that had been drifting since last year’s tsunami (海啸), sinking the vessel into waters more than 305 meters deep in the Gulf of Alaska and removing the danger it posed 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 is 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 vessel, a Canadian fishing vessel, 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 vessel, the Coast Guard began to fire, first with 25 mm shells, then a few hours later with ammunition (弹药)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.The plan to fire on the Japanese ghost ship was paused because ____________.
| A．the ghost ship was beyond the reach of the Coast Guard’s guns |
| B．state officials worried the ghost ship might give out radiation |
| C．the shells were not powerful enough to sink the ghost ship |
| D．a Canadian fishing boat wanted to save the ghost ship |
What’s the right order of the events related to the ship of Ryou-Un Maru?
a. Its long, lonely voyage came to an end.
b. The US Coast Guard sank it into the sea.
c. The ship began to float across the Pacific Ocean.
d. A big tsunami was caused by great earthquakes.
e. Bernice C claimed rights to save the ghost ship.
| A．d, c, e, b, a | B．a, b, d, c, e | C．c, e, d, a, b | D．b, a, d, c, e |
Which of the following could be the best title for the passage?
| A．Japanese ghost ship arriving at US |
| B．Tsunami garbage heading to US |
| C．Japanese ghost ship polluting the Pacific |
| D．Cannon fire sinking Japanese ghost ship |
