Researchers led by New York University neuroscientist Joseph LeDoux recently claimed to be the first scientists to erase a single memory. Working with rats, LeDoux’s team first【B1】______the animals to fear both a beep and a siren【B2】______giving them an electric shock every time either of the tones sounded. Then LeDoux gave half the rats the drug U0126, which is known to【B3】______with memory storage, and replayed the beep【B4】______electric shocks.
A day later, when LeDoux【B5】______back both tones to the rats, the animals that hadn’t been given the drug were still fearful of both sounds.【B6】______the rats that had been given the memory-blocking drug weren’t【B7】______of the beep, which they had last heard while【B8】______the influence of U0126.
【B9】______how U0126 exerts its amnesiac effect is【B10】______, but it may block the synthesis of proteins that help strengthen【B11】______between neurons and establish memories. The opportunity for erasure【B12】______during the act of retrieving a memory, because that’s【B13】______the memory is being updated and【B14】______again for long-term storage. " Only those memories that are activated are【B15】______," LeDoux says.
Drugs like U0126 may someday【B16】______sufferers of traumatic memories. A small group of human studies have been done on a drug called propranolol, which blocks the action of stress neurotransmitters that help【B17】______memories in the brain, but LeDoux’s work shows the【B18】______for greater precision. " You might be able to【B19】______the traumatic impact of memories in people," says LeDoux. " The good news is you wouldn’t be【B20】______off their memory bank. "
【B16】
选项
A、inspire
B、examine
C、analyze
D、benefit
答案
D
解析
动词辨析题。本段开始讨论U0126这样的记忆阻隔药物的社会价值和意义。后文还提到已有的记忆阻隔药物帮助医治创伤性记忆。由此可见,本句的意思是这类药物总有一天会帮助或惠及受创伤性记忆困扰的人们,故[D]benefit“使……受益”为正确答案。本段已经开始讨论药物的社会意义,不会再谈到对患者进行测试或分析等研究环节,故[B]examine和[C]analyze与本段主旨偏离,应排除。而[A]inspire“激励”主要涉及精神层面,而本段则主要陈述客观的科学实际,因此[A]也不符合文意,应排除。
