为什么狂犬病的致死率高

【参考答案】

狂犬病是一种非常严重的病毒感染,其致死率高的原因主要有以下几个方面:

1. 病毒的快速传播:狂犬病病毒通过伤口进入人体后,会迅速进入神经组织,并在其中大量繁殖。由于病毒的快速传播,患者往往在出现症状前就已经感染了大量病毒。

2. 病毒对神经组织的破坏:狂犬病病毒主要感染神经组织,并破坏神经细胞的功能。这会导致患者出现严重的神经系统症状,如肌肉痉挛、瘫痪、呼吸困难等,最终导致死亡。

3. 缺乏有效的治疗方法:目前还没有针对狂犬病的特效治疗方法。患者只能通过支持治疗和对症治疗来缓解症状,但无法清除病毒。

由于狂犬病病毒的快速传播和对神经组织的破坏作用,患者往往在出现症状后很快死亡,致死率非常高。因此,预防狂犬病的发生非常重要,例如及时接种狂犬病疫苗、避免接触野生动物等。

问答题
The 21st century learner has many educational traits that older educators may not be familiar or comfortable with. How does all of this impact the field of education? At the bottom of all this is the simple fact that the amount of information is growing almost as quickly as new technologies develop. We now process more information in 24 hours than what the average persons 500 years ago would process in a lifetime. By the time today's kindergartners graduate from grade 12, information will have doubled at least seven times while technological power will have doubled itself nearly nine times! And to think that the general structure of today’s university was solidly established by AD 1500! With the rate of information growth continuously accelerating, higher education today must place less emphasis on the amount of material memorized and more weight on making connections , thinking through issues, and solving problems. We must discard the notion that schools can teach everything, and every student will need to know how to be successful in their fields of choice. We must move beyond the old university model where the primary challenge of learning was to absorb a vast array of specific information. Learning is now a lifelong process of coping with change. The content of a particular lesson is less important than manipulating content resources. Learning how to learn is the basis of education today. The learning preference of the 21st century learners is to work in teams in peer-to-peer situations within a structured environment that affords a fair amount of flexibility. They look to he engaged in their learning and to be able to experience learning firsthand-to learn through exploration. They also tend to prefer visual and kinesthetic (运动感觉的) activities to reading and listening activities. Finally they want to learn things that matter. Students want to be challenged to reach their own conclusions, and to find their own results. The new technologies that are available in the field of education can help create a learning culture in which the learners enjoy enhanced interactivity and connections with others. The central issues now are: How can technologies be organized around student’s learning? How can we use these tools to help students think and communicate effectively? Higher education should place more emphasis on the amount of material memorized. The main challenge of learning for the students within the old university model was to absorb a vast array of specific information. The previous learners prefer to work in teams and through exploration. Using the new technologies can help create a learning culture in which the learners enjoy enhanced interactivity and connections with others. The central issues of the application of the new technologies are how technologies can be organized around students’ learning and how to use these new technologies to help students think and communicate effectively.
