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 both. For some years, the role of 1.______
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 digestion 2.______
can lead to high blood pressure in man and animals. Some individuals,
however, and some rats consuming large amounts of salt without 3.______
developing high blood pressure. No matter how strictly all environmental
factors were controlled in these experiments, some salt-feeding animals 4.______
never developed hypertension although a few rapidly developed very 5.______
severe hypertension followed by early death. These marked variations were
interpreted to result from differences in genetic constitution.
By mating in successive generations only those animals that succeeded 6.______
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 found. 7.______
The availability of these tow strains permits investigations not
heretofore possible. They provide a feasible laboratory model which to 8.______
investigate some clinical aspects of the human prototypes of hypertension.
More important, there might be the possibility of developing methods by 9.______
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 for the characteristics of the sodium chloride. 10.______ [br]
选项
答案
although——whereas/while
解析
本题为连词误用。本句已经有no matter how引导的让步状语从句,表示在环境因素严格控制下的两种不同情况,此处强调两者的对比,宜用whereas或while,而不是再次采用让步从句。
