(1)P1lder adults who eniov physical activitiestend to live longer than those who do not engage in such activities
P2:people who enjoy physicalactivities often also engage in social activities
Q:evaluate whether physical activityalone contributes to longevity
单独统计只社交不锻炼的人群的寿命,如果这群人寿命很长,就说明对长寿有贡献;如果没有,则是锻炼身体的原因。
(2)C:these large mammals did not, infact, migrate across a land bridge
P:no evidence of these animals or their remains has been found on Madagascar
Q:strengthen
在 AC 之间纠结。感觉 A 更直接,没有大陆桥哪里还能迁移,但是这是第一个假说里提到的,应该属于前提?如果是前提,A 就是反前提了。那C说了,现有这些生物,也不是大型哺乳动物的后代,既没有遗骸。也没有后代,那加强结论。

(一)引出讨论对象neural information processing is often likened to engineered systems(2B)
(二)新的发现burgeoning evidence suggests that neuronal communication cantranscend direct synaptic interactions./ synaptic transmission remains the most rapid form of neural communication(3A)比作无线信号传播, 解释啥叫volume transmission。
(三)the traditional synaptic transmission model 和volume transmission 的关系:并不否认旧的,但是有所发展:(1)synaptic transmission:immediate tasks (2)volume transmission: influence distant targets. (4B)(5B) |
