Scientists Develop Ways of Detecting Heart Attack

German researchers have (1) a new generation of defibrillators and early warning software aimed at offering heart patients greater protection (2) sudden death from cardiac arrest.

In Germany alone around 100,000 people die annually as a result of cardiac arrest and many of these cases (3) by disruption to the heart's rhythm. Those most at risk are Patients who have (4) suffered a heart attack and for years the use of defibrillators has proved useful in diagnosing (5) disruptions to heart rhythms and correcting them automatically by intervening within seconds. These devices (6) a range of functions such as that of pacemaker.

Heart specialists at Freiburg's University Clinic have now achieved a breakthrough with all implanted defibrillator (7) of generating a six-channel electrocardiogram(ECG) within the body. This integrated system allows early diagnosis of (8) blood-flow problems and a pending heart attack. It will be implanted in patients for the first time this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautern have developed new computer software that renders the evaluation of ECG data (9) .

The overwhelming (10) of patients at risk will not have an implanted defibrillator and must for this reason undergo regular ECGs. "Many of the current programs only (11) into account a linear correlation of the data. We are, however, making use (12) a non-linear process that reveals the chaotic patterns of heart beats as an open and complex system." Hagen Knaf says." (13) changes in the heart beats over time can be monitored and individual variations in patients taken into account." An old study of ECG data, based (14) 600 Patients who had suffered a subsequent heart attack, enabled the researchers to compare risks and to show (15) the new software evaluates the data considerably better.

听力原文：W: In the past 10 years, many scientists have studied the differences between men

and women. And they all got the same answer: The sexes are different, because their brains are different. And this, the scientists say, makes men and women see the world in different ways.

Boys, for example, generally are better than gifts at mathematical ideas involving objects and their relationships. Boys are also generally better than girls at the kind of hand and eye movements necessary for bail sports. Girls, on the other hand, generally start speaking earlier than boys. And they generally see better in the dark than boys and are better at learning foreign languages.

What makes men and women better at one thing or another？ The answer is the brain. The brain has two sides connected by nerve tracks. The left side is generally used for mathematics, speech and reading. The right side is used for artistic creation and the expression of emotions. In men and women, different areas in each side of the brain develop differently. In boys, for example, it's the area used for mathematics. In girls, it is the area used for language skills. Another interesting difference is that the two sides of a man's brain are connected by a smaller number of nerves than the two sides of a woman's brain are. So the flow of information between the halves of a man's brain is more restricted than that between the halves of a woman's brain. Some scientists say this influences some of our abilities.

According to the speaker, what is one of the advantages of girls？

A．They have better ideas about objects and their relationships.

B．They have more flexible hands and eyes.

C．They can see better than boys at night.

D．They can express their emotions better than boys.

第11题

听力原文： American scientists are developing maps that can identify areas of future floodi

ng. The maps also may help scientists estimate the possibility of extremely dry weather and severe storms.

Tom Jackson of the United States Department of Agriculture prepared the map after the April flood. He used in-formation provided by satellites in Earth orbit.

The maps are produced from dish receivers on the satellites. Each dish receiver measures the wetness of the soil by capturing the natural release of microwave radiation from the soil. The receivers turn rapidly. This provides complete coverage of each area the satellite passes over.

Mr. Jackson and other scientists have tested Aqua's equipment in airplanes and satellites flying over several states. Tile scientists used the tests to develop ways to change the information gathered into maps.

Mr. Jackson now plans to compare the microwave dish receiver findings with information from tests on Earth's soil. He will use instruments at Agricultural Research Service centers in four states. He also will study information provided by forty ground observation centers across the country

Why American scientists are developing these maps7

A．To estimate the extreme weather.

B．To develop the satellite technology.

C．To improve agricultural output.

D．To learn how to change information to maps more efficiently.
