PERTH—Search crews will send a submarine(潜航器)deep into the Indian Ocean on Monday for the first time to try to determine whether signals detected by sound-locating equipment are from the missing Malaysian plane's black boxes, the Australian head of the search said.
Angus Houst on said the crew on board the Ocean Shield will send the underwater vehicle sometime Monday evening. The Bluefin 21 submarine can create a sonar(声呐)map of the area to chartany wreckage(残骸)on the seafloor.
The move comes after crews picked up a series of underwater sounds over the past two weeks that were consistent with an aircraft's black boxes.
“We haven’t had a single detection in six days, and l guess it’s time to go under water,” said Houston.
“Analysis of the four signals has reduced the search area on the ocean floor. The experts have therefore determined that the Australian Defense Vessel Ocean Shield will stop searching with the Towed Pinger Locator(拖曳声波定位仪)later today and use the underwater vehicle Bluefin 21 as soon
as possible," he said at a news conference in Perth.
But Houston warned the switch to the submarine will not automatically "result in the detection of the aircraft wreckage. It may not.”
He said the submarine will take 24 hours to do each task, including two hours to dive, 16 hours to search the bottom, then two more hours hack up and four hours to download data.
Recovering the plane's flight data and cockpit(飞行员座舱)voice recorders is necessary For investigators to try to figure out what happened to Flight 370, which disappeared on March 8.
Houston said the search using the submarine will be a slaw and painstaking process.
The submarine takes six times longer to cover the same area as the pinger locator,and will need about six weeks to two months to examine the present underwater zone. The signals are also coming from 4,500 meters (15,000 feet) below the surface, which is the deepest the submarine can dive.
1.The submarine will be sent deep into the Indian Ocean on Monday to _____ .
A. create a sonar trap of the area

Different Kinds of Birds
Avocets
There are 4 different species of Avocet found around the world-Pied Avocet , Red-necked Avocet, Andean Avocet, and American Avocet. This bird is found in North and South America, Europe, and even Australia. This long-legged bird has webbed feet and an upturned, thin bill.
Bald Eagles
The bald eagle is found in wetlands and near coastlines. They have very large and broad wings, with a broad tail. The head and tail are white in color, which is the major distinguishable factor of the bald eagle. The long, hooked bill is yellow in color. They feed on fish, ducks, rabbits, geese, etc.
Eastern Bluebirds
These are around 61／2 inches in length .Such birds are found mainly in gardens woodlands, and orchards with the arrival of spring. Male Eastern Bluebirds are bright blue on the upper half and have a white belly. Female Eastern Bluebirds have a grayish head with shades of blue as well. New York and Missouri have named this creature as their state bird.
Flamingos
These pink-bodied birds with a unique beak, are generally found in large groups. The beaks are capable of removing mud before they can eat their food. Flamingos can be found in many African countries, areas of Florida, and one particular type of species is found only in the Andean highlands.
Kingfishers
There are over 90 various species of Kingfishers found in the woodland areas as well as wetlands across the world. They are excellent divers when it comes to catching fish in the rivers. Their pointed bills are what help them bag the catch. Kingfishers have good eyesight whether they are in air or underwater.

The sound of a mosquito can mean trouble in many parts of the world. The bite of the mosquito can be deadly. The insects carry serious diseases like malaria. It is estimated that almost 630,000 people died from malaria and malaria-related causes in 2012, and most of these cases were in African countries.
In the United States, a group of California scientists is working to develop a more effective and less costly substance(物质)to protect people from mosquitoes. The researchers are investigating the sense of smell in mosquitoes. They found the insects use the same receptor(感受器)for identifying carbon dioxide in human breath as they do for the smell of our skin. Anandasankar Ray, who is leading the investigation, says scientists tested more than a million chemical compounds(化合物)until they found a substance called Ethyl pyruvate. He says Ethyl pyruvate makes the mosquitoes' receptor inactive. ”When we apply Ethyl pyruvate to a human arm and offer it to hungry mosquitoes in a cage, very few of the mosquitoes are attracted to the human arm because only a few of them are able to smell it out,” said Ray.
Genevieve Tauxe, a member of the research team, says it was not easy to find the neurons (神经元)of nose cells that recognise both the smell of human breath and skin. "With the device used to examine mosquitoes, we are able to insert a very small electrode(电极)into the part of the mosquitoes' nose, where its smelling neurons are and where the smell is happening," said Tauxe.
Anandasankar Ray says a product based on Ethyl pyruvate may cost less to produce than DEFT，the most effective chemical treatment now in use. He says DEFT is too costly for most people who live in areas affected by malaria.
“Perhaps by finding smells that can attack other target receptors, we will be able to improve upon DEFT and finally have the next generation of insect behavior control products," said Ray.
1.The best title for the passage is most probably _______________________________.
A. Scientists Find New Substance to Fight Mosquitoes
B. A New Generation of DEET Has Been Developed to Kill Mosquitoes
C. Malaria一a Serious Disease Causing 630,000 Deaths

JANE AUSTEN(1775—1817)is often regarded as the greatest of English women novelists on the strength of her six completed novels．Known particularly for their social comedy and accurate description of human relationships，they are still as widely read today as they have ever been．
The seventh child of a country priest(牧师)，Jane Austen was born on 16 December 1775 at Steventon in Hampshire．Her father ,the Reverend George Austen，was an intelligent and sensitive man who encouraged Jane in her love of reading．From an early age she was familiar with the works of Henry Fielding，Sir Walter Scott，Richardson，Frances Burney and the poet George Crabbe．Her early attempts at writing include burlesques(滑稽作品)of popular romances．When her father retired in 1801 the family moved to Bath，which was later to feature in her novel Northanger Abbey(published in 1818)．After his death in 1805 the family moved first to Southampton and then in 1809 to Chawton in Hampshire．where Jane Austen is known to have written her last three novels：Mansfield Park(1814)，Emma(1816)and Persuasion(also published in 1818)．Although her other novels were written much earlier ,it was not until 1811 that Sense and Sensibility was first published．Pride and Prejudice，which followed in1813,features Jane Austen’own favourite hero，Elizabeth Bennet．
Surrounded by her lively and warm family and wholly buried herself in her writing and housework，Jane Austen led a life often known for its lack of events．She did，however ,attract several admirers and even accepted a proposal of marriage from one admirer-only to change her mind the following morning．Jane Austen’s independent life often seems reflected in her novels，which seem to display the world in miniature(缩影)．Sir Walter Scott praised Jane Austen for‘that unique touch which makes ordinary commonplace things and characters interesting’，while Somerset Maugham claimed that she had at her command ‘the most precious gift a novelist can possess’s that of keeping the reader’s interest．Jane Austen died in 1817．
