辛达雅思代报小编今天分享的内容含很多自然科学类阅览高频词，别的标示了一些初级生理学词汇最好看到要认识，这些词汇属于曾经雅思不要求但在近两年变革趋势中加剧的单词，同时也是托福高频单词。

 Using a standard lab test of memory, a mouse was placed in a box and given a small electrical shock to its feet. Normal mice remember this and freeze in fear if put back in the box the following day, but mice with Alzheimer’s scamper about unfazed. Yet when the researchers stimulated the dentate gyrus of these mice with blue light, they also froze, suggesting that they were now able to recall the original shock.

用一个规范的试验室回忆测试，一只老鼠被放在盒子里面并对它的脚给予微小电击。如果接下来几天把它放进盒子里，正常老鼠会记住而且因为惧怕而呆住不动，阿尔茨海默症老鼠则不受影响活蹦乱跳。但当研讨人员用蓝光刺激这些老鼠的齿状回时，它们一样会呆住不动，这标明它们能回忆起最初的电击感触。

【经典句式】

standard 规范的

electrical shock电击

Alzheimer’s阿尔茨海默症

stimulate刺激

recall回忆

original最初的

Holdingon to a fearful memory in the long term,however, requires the brain to strengthen the nerve connections (synapses) that link memory of the box to experience of the shock. This process, known as long-term potentiation, goes awry in the brains of Alzheimer’s patients. Consistent with this idea,the Alzheimer’s mice did not freeze when placed in the box but only when their neurons were illuminated.

可是要长时间坚持住惧怕回忆，要求大脑加强神经联络(突触)来连接盒子里的电击试验的回忆。这个进程，叫做长时程增强，没能在阿尔茨海默症老鼠大脑里顺利进行。和这共同的是，把阿尔茨海默症老鼠放在盒子里，只是照耀神经元，老鼠并没有呆住不动。

【经典句式】

hold on to sth坚持住

fearful惧怕的

in the long term 长时间地

require要求

strengthen加强

nerve connection 神经联络

process进程

consistent with … 跟……共同
