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.

Ms Pethrick was standing on a river bank Wednesday afternoon when the saltwater crocodile lunged (扑), locking its jaws on both her legs as it tried to drag her underwater.
Norm Pethrick, who with his wife had been collecting water, immediately went to help her. He jumped onto the back, poked (戳) the eyes of the crocodile and finally got his wife free.
Ms Pethrick was later taken to Royal Darwin Hospital for a medical treatment. The doctors said she was suffering eight puncture wounds (伤口) in her right leg, a puncture wound in her left leg and a serious cut to one of her fingers.
“This could have been a fatal and tragic situation,” said the general manager of Royal Darwin Hospital (RDH), Dr Len Notaras, according to a local report.
He said Ms Pethrick was saved by her husband’s “quick and diligent actions”.
Dr Notaras also said she would remain in hospital for three to four days and have an operation to clean the wounds, which are easy to get infected because of bacteria (细菌) on the teeth of the crocodile.

Nuclear power plants create energy using a chemical reaction that produces large amounts of heat. Reactors(反应堆)in Japan have many long, thin rods, called fuel rods(棒), which must be kept cool.
If the reactor’s fuel rods aren’t cooled, the reaction can burn out of control. That’s what happened at the two Japanese plants after the quake caused a power failure and the cooling systems malfunctioned(发生故障). This overheating could cause radiation to escape and sicken many people.
Japan’s 54 nuclear reactors are built to withstand the many small or moderate earthquakes the country faces each year. But Friday’s earthquake was one of the most severe earthquakes ever recorded.
People exposed to unsafe levels of radiation have a higher than normal risk of getting cancer. The Japanese government has been distributing potassium iodide(碘化钾)pills to people in the surrounding areas to protect those who may have come in contact with radiation from the power plant. The pills flood the body with healthy potassium iodide. The potassium iodide works to crowd out “bad” iodine in the body that may have been poisoned by radiation.
On Tuesday morning, 750 workers left the Fukushima Daiichi plant. However, 50 workers stayed behind to use sweater to cool the fuel rods. These dedicated employees are risking their own lives to save many others.
On Thursday, officials used helicopters, fire trucks, and water cannons to spray water on the reactors to cool the fuel rods. But it’s not clear whether these efforts were successful. Officials are now working on a power line to restore electricity to the plant. They hope this will help restart the plant’s cooling system and stop the fuel rods from leaking radiation.
小题1:The underlined word “evacuate” in Paragraph 1 probably means .
A.help | B.rest | C.stop | D.leave |
A.The local people are scared and ready to run away. |
B.The earthquake led to many deaths and caused damage to roads. |
C.The Japanese government has found a kind of pill that can treat cancer. |
D.The two stations were damaged because their cooling systems didn’t work. |
A.lack of help |
B.international aids |
C.the government’s efforts |
D.the result of the disaster |
A.a research paper |
B.a newspaper report |
C.a class presentation |
D.a chemistry textbook |
In a recent press release, the Brazilian government confirmed the existence of another isolated tribe of about 200 people living in the Vale do Javari reservation. The 200 people living in the Vale do Javari reservation. The reservation, located near the Peruvian border, is about the size of Portugal. At least another 14 isolated tribes, with a total population of about 2000, call the area home.
The newly observed group lives on four large straw-roofed buildings and grows corn, peanut and other crops.
Brazil’s National Indian Foundation (BNTF) first noticed the reservation in the forest using satellite maps, but it wasn’t until April that an airplane expedition was able to confirm the tribe’s existence. “The work of finding and protecting isolated groups is part of Brazilian public policy,” said the BNIF officer for Vale do Javari, Fabricio Amorim. “To confirm something like this takes years of hard work.”
BNIF estimates there are 68 isolated tribes living in the Amazon. The organization uses airplanes to avoid disturbing the tribes through personal contact, but that doesn’t mean others are so respectful of their right to privacy.
Illegal fishing, woodcutting and hunting bring people into the protected area. Oil exploration on the Peruvian side of the border is another threat. All kinds of criminals also invade the lands of the local groups, said Amorim. The outsiders can damage the land and influence the cultures of indigenous(土著的)peoples. They can also bring diseases which can wipe out the whole population that still lack even basic antibiotics(抗生素).
Brazil’s indigenous peoples won the legal right to their traditional lands in Brazil’s 1988 Constitution, which stated that all indigenous lands shall be divided and turned over to tribes within five years. Indigenous groups now control 11 percent of Brazil’s territory, including 22 percent of the Amazon.
Allowing indigenous groups the right homelands is not just a matter of human rights. The rest of the world can benefit from their knowledge. Mark Plotkin has spent years living with the people of the Amazon and learning from their traditional healers. In his lecture, he pointed out that many useful materials and knowledge, including numerous drugs, can be gained from listening to the indigenous groups of the Amazon. Besides this, they are also more effective at protecting the land, and less expensive, than hired rangers(护林人).
小题1:The underlined word in the first paragraph probably means “a state of ”.
A.separation | B.interaction |
C.satisfaction | D.excitement |
A.only live on a reservation designated for them |
B.prefer straw-roofed buildings to wooden ones |
C.keep contact with the outside world through airplanes |
D.have the legal right to the land they live on |
A.Privacy violation is common among the Amazon tribes. |
B.The laws dividing the lands of the tribes are far from enough. |
C.Modern civilization endangers the tribes and their cultures. |
D.It is hard to make public policy to protect primitive tribes. |
A.the lost human rights of the indigenous peoples |
B.the benefits of protecting the primitive tribes |
C.the value of traditional healing |
D.the indigenous peoples as guardians of the Amazon forest |
