英语四级考试备考复习资料大全1:阅读训练题

There is evidence that the usual variety of high blood pressure is, inpart, a familial disease. Since families have similar genes as well as similarenvironments, familial diseases could be due to shared genetic influences, toshared environmental factors, or to both. For some years, the role of one

environment factor commonly shared by families, namely dietary salt , has been studied at Brookhaven National Laboratory. Thesestudies suggest that long excess salt intake can lead to high blood pressure inman and animals. Some inpiduals, however, and some rats consume large amountsof salt without developing high blood pressure. No matter how strictly allenvironmental factors were controlled in these experiments, some salt-fedanimals never developed hypertension whereas a few rapidly developed very severehypertension followed by early death. These marked variations were interpretedto result from differences in genetic constitution.

By mating long successive generations of those animals that failed todevelop hypertension from salt intake, a resistant strain hasbeen evolved in which consumption of large quantities of salt fails to influencethe blood pressure significantly. In contrast, by mating only animals thatquickly develop hypertension from salt, sensitive strain hasalso been developed.

The availability of these two strains permits investigations possible. Theyprovide a plausible laboratory model on which to investigate some clinicalaspects of the human hypertension. More important, there might be thepossibility of developing methods by which genetic susceptibility of humanbeings to high blood pressure can be defined without waiting for its appearance.Radioactive sodium 22 was an important tool in working out the characteristicsof the sodium chloride metabolism.

21. The study of the effects of salt on high blood pressure was carriedout_______.

A. as members of the same family tend to use similar amounts of salt

B. to explore the long-term use of a sodium based substance

C. because it was proven that salt caused high blood pressure

D. because of the availability of chemically pure salt and itsderivatives

22. The main difference between S and R rats is their_______.

A. need for sodium 22 B. rate of mating

C. reaction to salt D. type of blood

23. We can infer from the article that sodium 22 can be used to_______.

A. control high blood pressure

B. cure high blood pressure caused by salt

C. tell the S rats from the R rats

D. determine what a sodium chloride metabolism is like

24. The most beneficial results of the research might be_______.

A. development of diets free of salt

B. an early cure for high blood pressure

C. control of genetic agents that cause high blood pressure

D. the early identification of potential high blood pressure victims

25. 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.

21. A 22. C 23. D 24. D 25. D
