A20. The following appeared in a budget proposal for the country of Salutopia.
“Over the past 20 years the birth rate in Salutopia has declined. During that same period, however, the number of physicians practicing in Salutopia has steadily increased, and the average number of patients treated by each physician has decreased by 30 percent. Meanwhile, average life expectancy in Salutopia has risen to 71 years, and the mortality rate fell significantly last year. Since such data indicate dramatic improvements in public health and a more than adequate supply of physicians in Salutopia, the national medical college need not expand and can perhaps even reduce its size.”
1The trend over the past 20 years does not indicate the following trend will be the same.
2The very reason for the longer life expectancy may just be the improvement of medical care.
3When the above-mentioned possibilities are considered the author's suggestion is therefore groundless.
还有一点，即使内需真的减少了，不代表外需不可以扩大阿
说不定外国人把这个country的长寿归结到医术呢，所以college可以培养出国的人啊
Perhaps the majority of physicians in the country of Salutopia come from other countries, and money is a major incentive in their occupations. If their economic condition changes, those physicians are more likely to leave Salutopia. Hence, nowadays, the system of medical experts of Salutopia is insatable and unsafe. We have enough reasons to encourage the national medical college to expand and increase its size.
1)agree with LZ-2;
2)the increased average life expectancy require more medical care related to the elders-a large demand for such medical service;
3)a large proportion of current physicians due to retirement in the near future, so more young physicians need to be educated and trained.
