But for those who experiencesevere trauma (创伤), such painful memories can leave people with life-changing mental conditions. So, what if traumatic memories did not have to cause so much ____207____ ? For now, the work is happening in mice.Neuroscientists usually define a singular memory as an engram--a physical change in brain tissue ____208____ a particular recollection. While at MIT in 2013, Steve Ramirez of Boston University and his research partner Xu Liu had a breakthrough: They were able to target the cells that ____209____ one engram in a mouse's brain and then implant a false memory. In their work, mice ____210____ in fear to a particular stimulus even when they had not been conditioned in advance.In their current work, Ramirez and his colleagues are investigating whether____211____ memories can be “overwritten" by positive ones. In their experiments, positive memories are created by putting male mice in cages with female ones for an hour, and negative memories are created by putting the mice in cages that deliver brief foot shocks. After a surgical operation on the mice, the researchers find that ____212____ positive memories while mouse is in a cage makes it less fearful. They think that this memory "retraining" may be helping to ____213____ some of the mouse's trauma. ____214____ , it is unclear whether those original fear memories are completely lost or just suppressed (抑制)._____215_____ Ramirez's team stresses that their work in mice is preliminary (初步的), they see treatment potential for humans down the road. Those suffering from PTSD or depression could have their memories _____216_____ , for instance, so that they don't have a strong _____217_____ response to painful recollections.If it's one day possible to alter human memory, who should be allowed to receive that treatment? And would the _____218_____ system be at a disadvantage if key witnesses and victims cannot remember a crime? These are questions New York University bioethicist (生物伦理学家) Arthur Caplan says are worth thinking about before the technology is ready for human clinical settings.As neuroscientists progress with their research, they say these _____219_____ issues are being taken into account. Ramirez sees the idea of _____220_____ memories as neither good nor bad. Like water, it just depends on how you use it.206．A．Forgettable B．Memorable C．SustainableD．Believable207．A．dignity B．struggle C．pain。
