英语四级选词填空练习题及答案英语四级选词填空练习题及答案：There is evidence that the usual variety of high blood pressure is,in part,a familiar disease.Since families have similar genes as well as similar environments,familiar diseases could be due to shared genetic influences,to shared environmental factors,or to both.For some years,the role of one environmental factor commonly shared by families,namely dietary salt(i.e.,sodium chloride),has been studied at Brookhaven National Laboratory.These studies suggest that chromic excess salt ingestion can lead to high blood pressure in man and animals.Some individuals,however,and some rats consume large amounts of salt without developing high blood pressure.No matter how strictly all environmental factors were controlled in these experiments,some salt-fed animals never developed hypertension whereas a few rapidly developed very severe hypertension followed by early death.These marked variations were interpreted to result from differences in genetic constitution.By mating is 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 tow strains permits investgations not heretofore possible.They provide a plausible laboratory model on which to investigate some clinical aspects of the human prototypes 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.Radioactive sodium 22 was an important "tool" in working out the characteristics of the sodium chloride metabolism.1.The study of the effects of salt on high blood pressure was carried out ______.a.as members of the same family tend to use similar amounts of saltb.to explore the long-term use of a sodium based substancec.because it was proven that salt caused high blood pressured.because of the availability of chemically pure salt and its derivatives2.The main difference between "S" and "R" rats is their ______.a.need for sodium 22b.rate of matingc.reaction to saltd.type of blood3.We can infer from the article that sodium 22 can de used to ______.a.control high blood pressureb.cure high blood pressure caused by saltc.tell the "S" rats from the "R" ratsd.determine what a sodium chloride metabolism is like4.The most beneficial results of the research might be ______.a.development of diets free of saltb.an early cure for high blood pressurec.control of genetic agents that cause high blood pressured.the early identification of potential high blood pressure victims5.Which of the statements best relates the main idea of this article?a.When salt is added rats and human beings react similarly.b.The near future will see a cure for high blood pressure.c.The medical field is desperately in need of research.d.A tendency toward high blood pressure may be a hereditary factor.答案：acddd英语四级选词填空练习题及答案：Directions: In this section, there is apassage with ten blanks.

In 1989 and 1990, Telefónica had the opportunity to enter Chile and Argentina, countries that shared many institutional and cultural characteristics with its home country but that were ___32___ more rapid market reform. Throughout the 1990s, Telefónica took what it learned in Chile and Argentina about reconstructing former state-owned telecoms to other Latin American countries that were privatizing their state telecoms and deregulating their telecom markets.These examples might lead the reader to believe that creating a global advantage is an easy task.
