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. 答案　21. A 22. C 23. D 24. D 25.

He was so pleased to eat its meat easily that he thought, "What a wonderful thing to have this all the time!" From then on, he stopped working and waited by the tree for more hares that would crash. He waited and waited one day after another, in vain,only to have a desert-ed field.

2020年7月英语四六级考试即将进行，各位小伙伴准备好了么？大家在备考时一定要多做真题，这样才能更好地把握题目难度和重点词汇等等。今天小编为大家带来2019年6月英语四级听力原文：试卷一听力篇章2（沪江网校），希望对你有所帮助~ My research focus is on what happens to our immune system as we age. So the job of the immune system is to fight infections. It also protects us from viruses and from autoimmune diseases. We know that as we get older, it's easier for us to get infections. So older adults have more chances of falling ill. This is evidence that our immune system really doesn't function so well when we age. In most of our work, when we were looking at older adults who've got an illness, we always have to have health controls. So we work very closely with a great group of volunteers called the One Thousand Elders, these volunteers are all 65 or over but in good health. They come to the university to provide us with blood samples to be interviewed and to help us to carry out a whole range of research. The real impact of our research is going to be on health in old age. At the moment, we are living much longer. Life expectancy is increasing at 2 years for every decade, that means an extra 5 hours a day. I want to make sure that older adults are still able to enjoy their old age, and that they are not spending time in hospital with infections, feeling unwell and being generally weak. We want people to be healthy even when they are old. 我的研究重点是我们的免疫系统在随着年龄的增长会发生什么变化。免疫系统负责对抗感染。它2020年7月英语四六级还能保护我们免受病毒和自身免疫性疾病的侵害。我们知道，随着年龄的增长，我们更容易感染。所以老年人有更容易生病。这证明当我们变老时，我们的免疫系统确实不能很好地发挥作用。在我们的大部分工作中，当我们看到患有疾病的老年人时，我们总是必须对他们进行健康管理。因此，我们与一大群人组成的志愿者团体紧密合作，这个团体叫“千个老人”，这些志愿者都是65岁或65岁以上，但健康状况良好。他们来这所大学是为了给我们提供接受预检的血样并帮助我们进行一系列的研究。我们研究的真正影响在于关注老年人的健康。目前，我们的寿命要比过去长得多。预期寿命是每10年就增加2年，这意味着每天增加5个小时。我想确保老年人仍然能够享受他们的老年生活，并且他们不会因为感染、身体不适和普遍虚弱而在医院呆上一段时间。我们希望人们即使在年老的时候也保持健康。 Questions 19—21 are based on the passage you have just heard. 请根据刚才所听的短文回答19-21题。 Question 19 What is the focus of the speaker's research? 问题19：这位男士研究的重点是什么？ Question 20 What are the volunteers asked to do in the research? 问题20：志愿者们在研究中被要求做什么？ Question 21 What does the speaker say will be the impact of his research? 问题21：这位男士说他的研究将会产生什么影响？ 以上就是今天为大家分享的内容啦，各位小伙伴利用好最后的时间认真备考。小编祝大家顺利通过6月英语四级听力原文：试卷一听力篇章2（沪江网校），希望对你有所帮助~ My research focus is on what happens to our immune system as we age.
