Read the following passage and blacken the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
The history of clinical nutrition, or the study of the relationship between health and how the body takes in and utilizes food substances, can be divided into four distinct eras: the first began in the nineteenth century and extended into the early twentieth century when it was recognized for the first time that food contained constituents that were essential for human function and that different foods provided different amounts of these essential agents. Near the end of this era, research studies demonstrated that rapid weight loss was associated with nitrogen imbalance and could only be rectified by providing adequate dietary protein associated with certain foods.
The second era was initiated in the early decades of the twentieth century and might be called “the vitamin period.” Vitamins came to be recognized in foods, and deficiency syndromes were described. As vitamins became recognized as essential food constituents necessary for health, it became tempting to suggest that every disease and condition for which there had been no previous effective treatment might be responsive to vitamin therapy. At that point in time, medical schools started to become more interested in having their curricula integrate nutritional concepts into the basic sciences. Much of the focus of this education was on the recognition of deficiency symptoms. Herein lay the beginning of what ultimately turned from ignorance to denial of the value of nutritional therapies in medicine. Reckless claims were made for effects of vitamins that went far beyond what could actually be achieved from the use of them.
In the third era of nutritional history in the early 1950's to mid-1960's, vitamin therapy began to fall into disrepute. Concomitant with this, nutrition education in medical schools also became less popular. It was just a decade before this that many drug companies had found their vitamin sales skyrocketing and were quick to supply practicing physicians with generous samples of vitamins and literature extolling the virtue of supplementation for a variety of health-related conditions. Expectations as to the success of vitamins in disease control were exaggerated. As is known in retrospect, vitamin and mineral therapies are much less effective when applied to health-crisis conditions than when applied to long-term problems of under nutrition that lead to chronic health problems.
It can be inferred from the passage that medical schools began to teach concepts of nutrition in order to
A. convince medical doctors to participate in research studies on nutrition
B. encourage medical doctors to apply concepts of nutrition in the treatment of disease
C. convince doctors to conduct experimental vitamin therapies on their patients
D. support the creation of artificial vitamins
Đáp án B.
Key words: medical schools, teach, concepts of nutrition, in order to
Clue: “As vitamins became recognized as essential food constituents necessary for health, it became tempting to suggest that every disease and condition for which there had been no previous effective treatment might be responsive to vitamin therapy. At that point in time, medical schools started to become more interested in having their curricula integrate nutritional concepts into the basic sciences”: Khi vitamin bắt đầu được nhìn nhận là thành phần thực phẩm thiết yếu cần thiết cho sức khỏe, có đề nghị được đưa ra là mọi bệnh tật mà trước đó không có cách điều trị hiệu quả có thể sẽ phản ứng với phương pháp điều trị bằng vitamin. Vào thời điểm đó, trường y khoa bắt đầu trở nên hứng thú hơn với việc đưa các khái niệm về dinh dưỡng vào chương trình giảng dạy thành bộ môn khoa học cơ bản.
A. convince medical doctors to participate in research studies on nutrition: thuyết phục bác sỹ y khoa tham gia vào những nghiên cứu về dinh dưỡng.
B. encourage medical doctors to apply concepts of nutrition in the treatment of disease: khuyến khích bác sỹ y khoa áp dụng các khái niệm về dinh dưỡng vào việc điều trị bệnh.
C. convince doctors to conduct experimental vitamin therapies on their patients: thuyết phục bác sỹ thử nghiệm phương pháp chữa bệnh bằng vitamin lên bệnh nhân.
D. support the creation of artificial vitamins: ủng hộ việc điều chế vitamin nhân tạo.
Vì có đề nghị là liệu pháp vitamin có thể chữa trị được những bệnh mà trước đó không có cách điều trị hiệu quả nên trường y khoa đưa các khái niệm về dinh dưỡng vào chương trình học để khuyến khích bác sỹ áp dụng các khái niệm này để chữa bệnh.
Vậy đáp án chính xác là B.
