1、Singing Alarms Could Save the BlindIf you cannot see, you may not be able to find your way out of a burning building ａｎｄ　that could be fatal. A company in Leeds could change all that with directional sound alarms capable of guiding you to the exit. Sound Alert, a company run by the University of Leeds, is installing the alarms in a residential home fｏｒblind people in Sommerｓｅｔａｎｄ　a resource centre fｏｒthe blind in Columbia. The alarms produce a wide range of frequencies that enable the brain to determine where the sound is coming from. Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be heard by humans. "It\'s a burst of white noise that people say sounds like static on the radio," she says. "Its life-saving potential is great."She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large smoke-filled room. It took them nearly four minutes to find the doｏｒwithout a sound alarm, but only 15 seconds with one. Withington studies how the brain ______ sounds at the university. She says that the source of a wide bａｎｄ　of frequencies can be pinpointed more easily than the source of a narrow band. Alarms basedon the same concept have already been installed on emergency vehicles. The alarms will also include rising ｏｒfalling frequencies to indicate whether people should go up ｏｒdown stairs. They were developed with the aid of a large grant from British Nuclear Fuels. 【单选题】

A.processes

B.produces

C.possesses

D.proceeds

正确答案:A

答案解析:句子主语是the brain，应和“处理”构成主谓关系，其他动词均不合适。所以选择A。

2、Breastfeeding Can Cut Cardiovascular RiskBreastfeeding can reduce the risk of a heart attack ｏｒstroke later in life ａｎｄ　could prevent hundreds of thousands of deaths each year, researchers said on Friday. Babies who are breastfed have fewer childhood infections ａｎｄ　allergies ａｎｄ　are less prone to obesity. British scientists have now shown that breastfeeding ａｎｄ　slow growth in the first weeks ａｎｄ　months of life has a protective effect against cardiovascular disease. "Diets that promote more rapid growth put babies at risk many years later in terms of raising their blood pressure, raising their cholesterol ａｎｄ　increasing their tendency to diabetes ａｎｄ　obesity-the four main risk factors fｏｒstroke ａｎｄ　heart attack." said ProfessｏｒAlan Lucas of the Institute of Child Health in London. "Our evidence suggests that the reason why breast-fed babies do better is because they grow more slowly in the early weeks."Lucas said the effects of breastfeeding on blood pressure ａｎｄ　cholesterol later in life are greater than anything adults can do to control the risk factors fｏｒcardiovascular disease, other than taking drugs. An estimated 17 million people die of cardiovascular disease, particularly heart attack ａｎｄ　strokes, each year, according to the World Health Organization. Lucas ａｎｄ　his colleagues compared the health of 216 teenagers who as babies had either been breastfed ｏｒgiven different nutritional baby formulas\' They reported their findings in The Lancet medical journal. The teenagers who had been breastfed had a 14 percent lower ratio of bad to good cholesterol ａｎｄ　lower concentrations of a protein that is a marker fｏｒcardiovascular disease risk. The researchers also found that regardless of the child\'s weight at birth, the faster the infants grew in the early weeks ａｎｄ　months of life, the greater was their later risk of heart disease ａｎｄ　stroke. The effect was the ______ fｏｒboth boys ａｎｄ　girls. "The more human milk you have in the newborn period, the lower your cholesterol level is, the lower your blood pressure is 16 years later, "Lucas said. 【单选题】

A.True

B.right

C.proper

D.same

正确答案:D

答案解析:句意应该是“该影响对男孩女孩都一样”，所以答案是D。

3、Better Control of TB Seen if a Faster Cure is FoundThe World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis. Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS ａｎｄ　drug-resistant forms of tuberculosis. Current treatments take at least six months. Patients have to ______ a combination of several antibiotic drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure fｏｒtuberculosis would be more effective. Now a study estimates just how effective it might be. A professｏｒof international health at Harvard University led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others. The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They tested the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. ａｎｄ　it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousａｎｄ　twelve ａｎｄ　two thousａｎｄ　thirty. That is, if a faster cure is developed ａｎｄ　in wide use by two thousａｎｄ　twelve. The World Health Organization developed the DOTS program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment. Earlier this year, an international partnership of organizations announced a plan to expａｎｄ　the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance fｏｒTB Drug Development says its long-term goal is a treatment that could work in as few as ten doses.【单选题】

A.make

B.take

C.try

D.test

正确答案:B

答案解析:从本句的前后句可以推测到本句想说的是“病人每天必须服用几种抗生素药物”，而服药只能选择take，其他几个动词都不合适。

4、Animal\'s "Sixth Sense"A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia ａｎｄ　East Africa, Wild animals, however, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" fｏｒdisasters, experts said.Sri Lankan Wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island\'s coast clearly missed wild beasts, with no dead animals found."No elephants are dead, not even a dead rabbit. I think animals can sense disaster. They have a sixth sense. They know when things are happening" H. D. Ratnayake, deputy directｏｒof Sri Lanka\'s Wildlife Department, said about one month after the tsunami attack. The waves washed floodwaters up to 2 miles inlａｎｄ　at Yala National Park in the ravaged southeast, Sri Lanka\'s biggest wildlife reserve ａｎｄ　home to hundreds of wild elephants ａｎｄ　several leopards."There has been a lot of scientific evidence about dogs barking ｏｒbirds migrating before volcanic eruptions ｏｒearthquakes. But it has not been proven," said Matthew van Lierop, an animal behaviｏｒassistant at Johannesburg Zoo. "There have been no ______ studies because you can\'t really test it in a lab ｏｒfield setting," he told Reuters. Other authorities concurred with this assessmetn."Wildlife seem to be able to pick up certain phenmenon, especially birds. There are many reports of birds detecting impending disasters," said Clive Walker, who has written several books on African wildlife.Animals certainly rely on the known senses such as smell ｏｒhearing to avoid danger such as predators. The notion of an animal "sixth sense" -ｏｒsome other mythical power-is an enduring one which the evidence on Sri Lanka\'s ravaged coast is likely to add to. The Romans saw owls as omens of impending disaster ａｎｄ　many ancient cultures viewed elephants as sacred animals endowed with special powers ｏｒattributes.【单选题】

A.additional

B.specific

C.especial

D.exceptional

正确答案:B

答案解析:本段的第一句是说明为什么这些迹象(evidence)没有得到科学验证。原因是科学家无法在实验室或野外进行特定的实验，以验证动物预见灾难的第六感觉。理解了上下文的意思，就知道选specific是最合适的。其他的三个选项的词义与上下文不符合，additional，especial和exceptional分别是“额外的”、“特别的”和“例外的”的意思。
