英语四级考试备考复习资料汇总1:阅读练习题

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

environment factor commonly shared by families, namely dietary salt (i.e.,
sodium chloride), has been studied at Brookhaven National Laboratory. These
studies suggest that long excess salt intake 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 long successive generations of those animals that failed to
develop hypertension from salt intake, 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, sensitive strain (the "S" strain) has
also been developed.

The availability of these two strains permits investigations possible. They
provide a plausible laboratory model on which to investigate some clinical
aspects of the human hypertension. More important, there might be the
possibility of developing methods by which genetic susceptibility (敏感性) 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.

21. 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 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 its
derivatives

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
