Eating too much fat can ___________ heart disease and cause high blood pressure.
A) attribute to B) attend to C) contribute to D) devote to
By mating in successive generations only those animals that failed to develop hypertension from salt ingestion, a resistant strain (the" R" strain) has been evolved in which consumption of large quantities of salt fails to influence the blood pressure significantly. In contrast, by mating only animals that quickly develop hypertension from salt, a sensitive strain ("S" strain) has also been developed.
The availability of these two strains permits investigations not heretofore possible. They provide a plausible laboratory model on which to investigate some clinical aspects of the human proto - types of hypertension. More important, there might be the possibility of developing methods by which genetic susceptibility of human beings to high blood pressure can be defined without waiting for its appearance.
Which statement relates the main idea of this passage？
A．When salt is added to their diets, rats and men react in much the same way.
B．The near future will see a cure for high blood pressure.
C．Modem research has shown that high blood pressure is a result of salt in the diet.
D．A tendency toward high blood pressure may be a hereditary factor.
The study also found that the type of alcohol consumed -- beer, wine or liqour -- was unimportant. Any of them, or a combination, was protective, researchers reported in today's Journal of the American Medical Association. "No study has shown benefit in recommending alcohol consumption to those who do not drink", cautioned the authors, led by Dr. Ralph L. Sacco of Columbia University College of Physicians and Surgeons in New York. But the new data support the guidelines of the National Stroke Association, which say moderate drinkers may protect themselves from strokes by continuing to consume alcohol, the authors said.
The protective effect of moderate drinking against heart attacks is well established, but the data has been conflicting about alcohol and strokes, the authors said. The new study helps settle the question and is the first to find blacks and Hispanics benefit as well as whites, according to the authors. Further research is needed among other groups, such as Asian, whom past studies suggest may get no stroke protection from alcohol or may even be put at greater risk.
Among groups where the protective effect exists, its mechanism appears to differ from the protective effect against heart attacks, which occurs through boosts in levels of so-called "good" cholesterol, the authors said. They speculated alcohol may protect against stroke by acting on some other blood trait, such as the tendency of blood platelets to clump, which is key in forming the blood trait, such as the tendency of blood platelets to clump, which is key in forming the blood clots that can cause strikes.
The researchers studied 677 New York residents who lived in the northern part of Manhattan and had strokes between July 1,1993, and June, 1997. After taking into account differences in other factors that could affect stroke risk, such as high blood pressure, the researchers estimated that subjects who consumed up to two alcoholic drinks daily were only half as likely to have suffered clot-type strokes as nondrinkers. Clot-type strokes account for 80 percent of all strokes, a leading cause of US deaths and disability. Stroke risk increased with heavier drinking. At seven drinks per day, risk was almost triple that of moderate drinkers.
An expert spokesman for the American Heart Association, who was not involved in the study, said it was well-done and important information. But it shouldn't be interpreted to mean, "I can have two drinks and therefore not worry about my high blood pressure or worry about my cholesterol," said Dr. Edgar J. Kenton, an associate professor of clinical neurology at Thomas Jefferson University Medical College in Philadelphia. Instead, he said, the study provides good reason to do further research and to add alcohol to the list of modifiable risk factors for stroke.
The new study conducted by Dr. Sacco and his colleagues is unique in that ______.
A．it refutes early studies on the protective effect of moderate drinking against heart attack
B．it confirms early studies of moderate drinking against heart attacks
C．it helps to resolve the disputes over the effect of moderate drinking against stroke
D．it finds that moderate drinking can benefit people of different races equally well
All the parts are dependent on each other and work together for the accomplishment of the total business of the machine.The locomotive must be provided with fuel, such as coal or wood or other combustible(易燃的)substance，the consumption of which provides the force or energy of the machine.The animal body must be provided with fuel, which is called food, which similarly provides the energy of the animal.
Oxygen must be provided for the combustion of the fuel in the locomotive and of the food in the body.The locomotive is composed of special parts，the fire box for the storage and combustion (燃烧)of fuel; the steam pipes for the carriage of steam; the wheels for locomotion (移动); the chimney for throwing off waste.
The animal body is similarly composed of such parts as the stomach for the storage and digestion of food, the organs for the throwing off of waste water, the blood vessels for the carriage of oxygen and food-holding blood, the legs or wings for locomotion.
1.The body of an animal is like a locomotive in that ().
A.it is composed of many parts that work just like different parts of a locomotive
B.it can do some particular kind of work
C.it works like all the machines in the world
D.both the animal and the locomotive need coal or wood as their fuel
2.Every part of the animal body().
A.works independently
B.works dependently on each other
C.looks like the same as that of a machine
D.has the same structure as that of a machine
3.The energy of an animal is provided by().
A.throwing off waste
B.the combustion of fuels such as coal or wood
C.consumption of food
D.the carriage of blood
4.The function of animal s legs is like__of a machine.
A.the wheels
B.chimney
C.steam pipes
D.the firebox
5.The steam pipes of a locomotive work like the()of an animal body.
A.stomach
B.blood vessels
C.legs
D.wings
