论文部分内容阅读
人教社新编高中《生物》（选修）课本第193页有如下叙述:“特异性免疫是指人出生后,在生活过程中通过感染或预防接种等,受到有关病原体的刺激而产生的一种专门对这种病原体起作用的防御功能。”、“人在患过传染病后获得的免疫叫做自然免疫。”那么,“自然免疫”一词是否专用于特异性免疫?非特异性免疫也称自然免疫,两者如何区分?特异性免疫是否都是在人出生后通过感染或预防接种获得的?对这类问题,在教学中极易造成误解。下面就如何理解有关概念,谈谈笔者的学习体会,供参考。
The following is the description on page 193 of the textbook “Biology” (Electives) of the Senior People’s Education College. “Specific immunity is a disease that is caused by the stimulation of pathogens through infection or vaccination after birth. A defense function that works specifically for this pathogen.” “The immunity that people get after having an infectious disease is called natural immunity.” Then, is the term “natural immunity” specific to specific immunity? Nonspecific immunity is also known as How does the natural immune system differentiate between the two? Is specific immunity obtained through infection or vaccination after birth? This type of problem can easily be misunderstood in teaching. Here’s how to understand the concept, talk about the author’s learning experience for reference.
