Sometimes fishing ships disappear: Captains turn off the radios that broadcast their locations, leaving regulators wondering whether the ships are fishing illegally. Now, researchers have shown that albatrosses(信天翁)bearing small detectors can find these doubtful ships, even in the middle of the open ocean. After a 6-month study with the large seabirds, the researchers say that more than one-third of ships in the southern Indian Ocean are fishing illegally.
“These are animal police,” says Boris Worm of Dalhousie University. “You’re empowering animals to survey their own environment, ”Worm says. “That’s pretty cool.” The method could also help albatrosses themselves, which can be killed when they get caught or accidentally eat fishing hooks. The researchers will be there on time.
Illegal fishing is a major concern for environment biologists, especially in remote areas. Over the past decade, scientists have studied the problem with data from automatic identification systems (AISs) on ships, which send their identity, location, speed, and direction to satellites. But AlSs can be turned off. Researchers suspect that fishing ships turn off AISs when they are fishing illegally or want to prevent competitors from knowing where they are getting a good catch.
Albatrosses make good spies. The birds, which live on fish, can spot a fishing ship from as far away as 30 kilometers. Some species fly hundreds or thousands of kilometers while hunting. Between December 2018 and June 2019, the birds met 353 ships. Those locations were sent to the lab in less than 2 hours. If they did not match the locations of ships with an active AIS, the team knew the ships had switched it off. In international waters, 37% of detected ships had their AlS switched off and fished illegally.
Although the albatrosses can detect ships, they cannot track them over longer distances, one scientist says. He says, “What you need to do is to look for patterns to take pictures as evidence.” More albatrosses will be arranged in March and April around the Prince Edward Islands in the southern Indian Ocean to reveal the illegal fishing.

Somali pirates(海盗) robbed three Thai fishing ships with 77 sailors on board nearly l, 200 Miles off the Somali coast, the farthest-off-shore attack to date, an officer said Tuesday.
Pirates have gone farther south and east in answer to increased patrols(巡逻)by warships off the Somali shore. The robbing of the three ships Sunday was about 600 miles outside the normal operation area for the international force, said a spokesman.
The spokesman said the attack so far out at sea was a clear sign that the international patrols against pirates were having a “marked effect on pirate activity in the area”.
“Once they start attacking that far out, you’re not even really talking about the Somali basin or areas of water that have any connection with Somalia,” said an officer, Roger Middleton. “Once you’re that far out, it's just the Indian Ocean, and it means you’re looking at trade going from the Gulf to Asia, from Asia to South Africa. ”
“This is the farthest robbing to date. They are now operating near the Maldives and India,” said another officer.
The three ships--the MV Prantalay 11, 12, and l 4—had 77 members on board in total. All of them are Thai, the spokesman said. Before the Sunday robbing, pirates held l l ships and 228 sailors.
Pirates have increased attacks over the past year in hopes. of catching more dollar payments. Because of increased patrols and defenses on board ships, the success rate(率)has gone down, though the number of successful attacks has stayed the same year over year.
1.The pirate attack reported in the text happened __________.
| A．far out in the Indian Ocean |
| B．in the normal patrol area |

| A．More goods on board are lost. |
| B．Pirate attacks happen in a larger area now. |
| C．The number of attacks has stayed the same these years. |
| D．Pirate attacks are as serious as before along the Somali coast. |
3.Which is true about the warship patrols according to the text?
| A．The patrols are of little effect. |
| B．The patrols are more difficult. |
| C．More patrols are quite necessary even in Asia. |
| D．The patrols only drive the pirates to other areas. |
4.How many sailors were held by the pirates up to the time of the report?

Sea urchins (海胆) are small creatures, but what’s really remarkable about them is that they eat anything that happens to float by. They have really sharp teeth they use to rid rocks of algae (海澡), which makes them pretty valuable especially in places like Hawaii where algae are threatening the coral reefs. In the summer of 2019, 500,000 of them were used to deal with the algae.
The problem started when non-native algae were introduced to the ecosystem of Kane’ohe Bay in the 1970s. Because they had no enemies, they ended up taking over the bay, according to the National Marine Fisheries Service (NMFS). The algae blocked sunlight from reaching the coral, which in turn affected the local fish because they changed the chemistry of the water.
That's when the NMFS turned to sea urchins that loved to devour the algae. But they had to grow to the size of a cherry tomato before they could be used. Since 2011, sea urchins have been grown and used to handle the algae problem. Some of the funds are available due to an unfortunate incident.
In 2005, a ship was grounded on a shallow reef near Kane’ohe Bay. When the ship was removed, 20 acres of reefs have been damaged. When there is environmental damage, the NMFS and other agencies receive funds from the wrongdoers and the funds are used to restore the damage. Some funds were spent on other projects like the sea urchins.When they are large enough, divers carefully place them on the reef.
Algae isn’t the only thing that threatens the coral reefs. Climate change and the effects of fishing and tourism in the area also endanger the coral reefs. But turning to sea urchins instead of man-made solutions seems like the best way to go.
1.Why are sea urchins regarded as outstanding creatures?
A.They are tiny but have teeth. B.They can keep the ocean clean.
C.They are useful in removing algae. D.They grow on coral reefs with algae.
2.What happened after non-native algae arrived at Kane’ohe Bay?
A.They helped the coral reefs to survive. B.They spread to every corner of the bay.
C.They didn’t fit in with the new surroundings. D.They fought against other species to get food.
3.What does the underlined word “devour” in paragraph 3 mean?
A.Eat. B.Block. C.Tease. D.Attract.
4.What does the author suggest doing to save coral reefs?
A.Relying on humans’ solutions. B.Banning fishing and tourism.
C.Employing divers to handle algae. D.Letting nature take care of nature.

A ship that sank off the coast of California decades ago was recently reconstructed in detail. The 3D digital model even included hundreds of sponges (海绵动物) that have gathered on the ship’s surface since it sank.
Named American Heritage, the supply ship sank in Santa Monica Bay on May 4, 1995, and for decades its exact location was unknown. Researchers with the Monterey Bay Aquarium Research Institute (MBARI) spotted a strange shape in that area in 2008. But it wasn’t until May 2018 that MBARI scientists identified its exact location and mapped the site in detail, showing what appeared to be a shipwreck (失事船只).
Even then, the identity of the shipwreck was uncertain. Yet another MBARI team revisited the location to do further exploration. They sent remotely operated vehicles (ROVs) and took photos of the damaged ship. Though it was covered with deep-sea sponges and other animals, the scientists were able to spot letters spelling out its name, confirming that the shipwreck was American Heritage.
As one of the MBARI scientists who found American Heritage, chief ROV pilot Knute Brekke had worked on the ship before. And he was on duty with the diving company American Pacific Marine — the owner of American Heritage — the night the ship began taking in water and eventually sank.
MBARI spokesperson Kim Fulton -Bennett said to Live Science about the discovery, “The model is not complete, as floating ropes and poor visibility kept the pilots from getting too close to the wreck. But the 3D reconstruction is detailed enough to show that American Heritage is now home to thousands of sponges. Shipwrecks often turn into the shelter for diverse communities of ocean life.”
1.What is the main idea of the text?
A.A valuable treasure was discovered.
B.Special sponges were found under sea.
C.3D model reconstructed a sunken ship.
D.A sunken ship was gotten out of water.
2.Which is the right order of the following events?
① Something strange was found in the area.
② ROVs were sent under sea to take photos.
③ A ship sank in Santa Monica Bay.
④ The identity of the ship was confirmed.
⑤ Scientists tried to locate the shipwreck.
A.②③⑤④① B.③①⑤②④
C.⑤③①④② D.④③①②⑤
3.What can we learn about Knute Brekke?
A.He was familiar with the sunken ship.
B.He was in charge of a diving company.
C.He was responsible for the rescue work.
D.He was the first one to witness the accident.
4.What’s Kim Fulton-Bennett’s attitude towards the 3D model?
A.Critical. B.Doubtful. C.Amazed. D.Objective.

China may send naval ships to the seas off Somalia to help the fight against piracy（海盗行为） there, Chinese media on Wednesday quoted a Vice Foreign Minister as saying at the United Nations, Reuters reported.
"China is seriously considering sending naval ships to the Gulf of Aden and waters off the Somali coast for escorting operations in the near future," the Xinhua news agency quoted He Yafei as saying. He Yafei, speaking at a Security Council ministerial meeting, said that China welcomed global cooperation in the fight against Somali piracy, and supported efforts by other countries to send ships to the region, Xinhua reported.
Earlier this month a leading Chinese military strategist, Major-General Jin Yinan, urged the government to send ships, in comments generating debate about combating piracy in a country which has generally confined its navy to waters near home. Jin told a Chinese radio interviewer that "nobody should be shocked" if his government one day decided to send navy ships to deal with the pirates, whose recent victims have included ships from Chinese mainland and Hong Kong. Jin is the head of a strategy institute at China's National Defense University.
While the military strategist is urging an active part, other scholars think the government should be cautious before a decision is made. The Chinese military ships should go there "only within the UN framework," said Pang Zhongying, a professor of international relations with Renmin University of China. Pang added that he also had some concerns over the Chinese navy's capability. "I don't think the Chinese navy has the capability to fight against unconventional threats far in the ocean," he said, adding supplying and refueling in the Indian Ocean are key challenges.
A sharp increase in attacks at sea this year in the busy Gulf of Aden and Indian Ocean off Somalia has pushed up insurance costs, brought the Somali pirates tens of millions of dollars in ransom（赎金） and prompted foreign warships to the area. Among the captured ships are a Saudi supertanker loaded with $100 million of crude oil, the Sirius Star, and a Ukrainian cargo ship carrying some 30 Soviet-era tanks. The victims have also included a Hong Kong-flagged ship with 25 crew aboard and a Chinese mainland fishing boat reported seized off Kenya. NATO ships began anti-piracy operations off the Somali coast in late October, but they have failed to stop the attacks.
56. This year, many ships from different countries have been captured by the Somali pirates except _______.
A. a Saudi supertanker B. a Ukrainian cargo C.NATO ships D. the Sirius Star
57. The underlined word "confined" in the third paragraph most probably means ________.
A. involved B. restricted C. confirmed D. contract
58. From the passage, we learn that _______.
A. China has sent its navy to fight the Somalia pirates
B. some countries have launched their anti-piracy operations
C. the Somalia pirates often attacked foreign warships for ransom
D. The Chinese navy hasn’t the capability to travel far to combat pirates
59. When the Major-General Jin Yinan said "nobody should be shocked", he actually indicated that ________.
A. the Chinese people should keep calm about the government's decision
B. no one should be frightened by the pirates' attack as the Chinese navy will defend them
C. it is reasonable for China to send its navy to fight against the Somalia pirates
D. if China had dealt with the pirates earlier, nobody would have been shocked
60. Professor Pang Zhongying’s main concern about the Chinese naval ships is that _______.
A. adding supplying and refueling far in the ocean is really a challenge
B. the Chinese navy has never fought against such unconventional threats
C. the fighting against pirates is not within the UN framework
D. the attacks in the Gulf of Aden and Indian Ocean off Somalia has increased sharply

Nearly a quarter-century after a German boy threw a message in a bottle off a ship in the Baltic Sea, he’s received an answer.
A 13-year-old Russian, Daniil Korotkikh, was walking with his parents on a beach when he saw something lying in the sand.
“I saw that bottle and it looked interesting,” Korotkikh told The Associated Press on Tuesday. “it looked like a German beer bottle and there was a message inside. ”
It said, “My name is Frank, and I’m five years old. My dad and I are traveling on a ship to Denmark. If you find this letter, please write back to me, and I will write back to you.” The letter, dated 1987, included an address in the town of Coesfeld.
The boy in the letter, Frank Uesbeck, is now 29. His parents still live at the letter’s address.
The Russian boy and the German man met each other earlier this month through an internet video link. The Russian boy said he did not believe that the bottle actually spent 24 years in the sea. He believed it had been hidden under the sand where he found it for a long time.
Uesbeck was especially happy that he was able to have a positive effect on a life of a young person far away from Germany. “It‘s really a wonderful story,” he said. “And who knows? Perhaps one day we will actually be able to arrange a meeting in person. ”
